Are you upgrading your transmission as well I assume or is it already upgraded? Or...does it not need upgrading?

Yeah the crank set me back about 3k and I am upgrading the radiator and clutch to the OS Giken clutch. My car is a manual so no transmission rebuild for now. I actually had a long discussion with vortech about the V7 and it will mount the same way the V3 SCI will but the shell is just a little larger but we measured and everything looks like it will clear pretty easily. But Soho has a full fab shop so if we need to modify a bit we could but from what we are seeing we may just add some bracing to the existing mount to prevent flexing at high RPMs and call it good but we don’t really think it needs that.

Sweet.
So If I ever upgrade to a V7-YSi billet head unit, I know it would fit our vehicles, along with the Stillen Upper Manifold.
I can talk to SOHO about fabricating the parts to have it fit my vehicle is what you're saying? Or did I misunderstand somewhere?

Also, Update on my Stage IV engine from Kyle @IPP:
- I talked to him and he said they would have a pretty accurate timeline on when the engine will be finished / shipped out to me by sometime in the middle of April. I'm super stoked for it and definitely cannot wait until middle of April. Just wanted to let you guys know how the Engine is going :)

Thanks! (:

Yeah it looks like the existing mounting from Stillen will work for the V7 unit. Soho will just watch it closely when they are tunning it to make sure the bracket is solid and doesn’t flex under heavy load. So that is why I said that they might add some reinforcement to the bracket if needed. Not yet for sure if it is necessary at this point. Will follow up with an update soon when we start tunning.

When you say existing mounting from Stillen, are you saying the same bracket that came with the Stillen SC kits with the V3 head units will work for the V7 YSi unit, V7 YSi-B unit or none of the above and that you just meant only the stillen manifold?

I heard you need to make a whole new mounting bracket for the V7 head unit for our vehicles but I could be wrong!

Reinforcement to the bracket if needed which means the existing bracket that came with the stillen kit for the V3 head units, just adding some reinforcement to that object correct?

Sorry haha just trying to make sure I understand :D
Thanks for the reply!

It’s all good...

Yes the same bracket that came with the Stillen Kit yes Vortech said it would fit the V7 head unit and we did some measurements based upon some drawings they shared with us and it looks like it will. The V7 and V7 YSIB are the same size so it will work.

From my understanding the 350Z needed to make a whole new bracket because of clearance issues but the 370Zs have more clearance in that area. I will share my final results with everyone when I am done and the great thing about it is that Nick from Soho will have a solution for us if something has to be done custom to make it fit.

Yes if need be we will reinforce the existing bracket from Stillen if we need the added support but I dont think we will need to based upon what we were told from Vortech.

cupcakez 03-24-2018 04:57 PM

Thank you Ben. I appreciate your responses :)
It helps a lot and helps me make my future decisions on what I will do with my vehicle.
Im really glad to hear that there is clearance in our 370 vehicles, and to hear that the v7 head units both fit on the existing stillen bracket that initially came with the v3 head unit.
I cant wait to hear the final results of what was used and what needed to be used / deleted / added / etc.

The piping for it -- I would assume that it just needs to be a little bigger than the previous piping, since the material can still be the same.

Niceee, Im glad to learn a lot :D

*Update*!!!

So my tuner helped me find out some important information regarding 1700x ID and 1300x ID [vs] 1050x ID. He found out that for my current applications -- because I am not running serious power with the current mods I am about to put into my vehicle, it is best I have 1050x ID's rather than 1300x ID or the 1700x ID.

The reason for this is because it is the physical limitation of the injectors.
The minimum amount of fuel will release too much for what my applications are at the moment even at the smallest pulses. ECUtek tuning cannot compensate and control it in this case, and so it is best I go for the 1050x ID's for now.
Once I upgrade to serious power, then it will be appropriate for me to purchase 1300s / 1700s and I can sell the 1050x ID's for cheap to someone else who may need them! Yay!

I also found out I won't be needing an oil cooler just yet, until I start seeing constant temperatures above 220+ (F).

As for a Transmission cooler, I will be putting that to the side as well because I will be replacing the entire transmission with a new custom built one from Level 10 Transmissions sometime next year.

For now I will be running 91 Octane in the beginning when my car is first repaired / upgraded hopefully in late April / Early May!

After it runs smoothly, I will upgrade the fuel system with the CJM S1-SE fuel return system in conjunction with a twin fuel pump, two hydramats, and twin walbro 450 setup.
My tuner said having two fuel pumps will definitely run the fuel a lot hotter which could be a serious issue, so I will have to find some way to keep it cool when running the twin fuel pump module from CJM -- If anyone has any ideas please let me know :)

Also, my tuner also said the A2A kit will lose some boost pressure being the A2A kit that it is, but that's okay as long as I can run the car safely while still pushing it the furthest it can go,

I spoke to Kyle from IPP regarding upgrading the rev limiter and how to do so with the stage 4, 11.0:1 Compression Ratio engine that I have being built. He suggested I get the ATI stock size pulley if I wanted to do so, and that's what I did -- purchased that pulley yesterday night.

I also found out that the engine harmonics will remain similar to the original stock engine -- so the knock sensitivity does not need to be recalibrated. And I know that our stock 370z engines use I beam rods which is good for higher RPMs, whereas Kyle from IPP uses H beam rods -- so I asked him if it would affect the rev limiter at all and if I should lower it or if it was safe to keep it the same. He said it could stay the same, so that's good. :)

Hopefully this information is able to help others out there who may be wondering similar / same things either now or in the future!

Thank you for reading!

Well I am interested how the 11.0 CR goes with the boosted application. I like the idea but am glad you will be leading the example. You mention going RFS with twin pumps etc, but needing smaller injectors because you will be going overkill at the moment? So you will be starting with single pump, returnless fuel system on 1050x and then will switch to twin pump RFS and bigger injectors later on?

That's correct.
My tuner recommends that I start off small and then upgrade as each step we take is proven safe & reliable in terms of drive-ability.

I will be starting with the single stock modified stillen supercharger kit pump, returnless fuel system on 1050x which my tuner said would be perfectly fine at the moment.
I will then switch to the twin pump module from CJM and get bigger injectors once I upgrade the supercharger headunit from 928 or Vortech -- since I have triple pulleys sitting in my room waiting and itching to be replaced to upgrade the spinning efficiency -- as this will also increase said boost.

I will then change to flex fuel at the same time getting the CJM S1-SE and probably a 34 row oil cooler to keep temperatures down since I will be running the twin pump with twin walbro 450s.

I will definitely be constantly updating the OP so people can follow the timeline, so pay close attention :D It is slowly adding things each time I do something such as order a part, receive a part, install a part, etc.

Will include all the ups and downs of this journey leaving nothing out! No filters xD

*UPDATE*
I called Vortech Engineering today and asked about the impeller / ceramic bearing upgrade that 928Motorsports provides. Vortech said the cost to upgrade the SCi unit to the SC unit is $306. All they do is replace it with an upgraded impeller. I asked about the ceramic bearing that 928 gives and if Vortech does the same, and they said no.
Then I asked if it had any advantages they know of, and he said no -- at least not any solid data to prove the bearings helped it perform better.

Vortech also said that 928 is not even licensed to perform upgrades on Vortech units, and that they just made their own parts and deemed it so.
Apparently they do not know how to put back the supercharger together properly or take it apart, and if it is done correctly -- then it is done more incorrectly than correctly.
As a result of this, Vortech is receiving "quite a lot" of the 928Motorports blower upgrades for reparations because they break. And they break simply because it is not put back together properly and they do not know what they are doing more than they do know what they are doing.

Guy at Vortech also said he recommends that people do not send it into 928 for the super-vortech premium package upgrade.

I wanted to share this information with the community for anyone thinking of sending it to 928 or not.
If so, just send it into Vortech since they are the ones that built the units in the first place so they should know how to upgrade it properly as well.

Saved me about $1,000 USD, because I was planning to pay a rush order fee, rush shipping, and the whopping $1236 for the premium package upgrade from 928.
Now that I know I only need to spend $306...I can spend that money I was GOING to spend on something else! LOL Such as maybe a CJM S1-SE return fuel system xD

PS -- Also, I live in CA and Vortech HQ is also located in Southern California (I'm in Northern).
I feel a lot more at ease and safe sending it to Vortech HQ rather than 928...which is across the country T_T

husam2012 04-02-2018 10:45 AM

Since you are located in California, are you going to be tuned by SpecialtyZ? If not, I definitely recommend it.

Also, it seems like your tuner might not know much about 370Zs... An oil cooler is a must for a stock car that is driven hard as oil temps reach 250-280 easily in the summer. Add 50% more power and you have a vehicle going into limp mode within a few power pulls.

About Level 10, I would never send my vehicle there after all the failure's I've seen. You have Fast Intentions located in your state.. Why go farther?

For your transmission, a cooler is pretty much mandatory when you boost the car. Heck, some of these transmissions fail with full bolt ons and hard driving. (lots of heat)

cupcakez 04-02-2018 10:59 AM

Well, I've never driven my car in the summer, so it's not my tuner's fault that I declined the Oil Cooler. He /did/ recommend that I get an oil cooler as an absolute necessary thing, but I told him my car is driving 180 - 220 the entire time I've driven it so far.

Then again, I haven't driven it in the summer. I said if I ever see constant 220+ then I will get an oil cooler asap, but as of right now, I'm okay.

Why not send it to FI? Because I don't think that they do Automatic Transmission upgrades..?
A big part of my build is basing it off of Evan's (StillenZ84 user on here) build.
He got the level 10 transmission in his car, and he also drives 7 AT just like I do.
So that is also another reason why I decided to base my build off of his.

Unless FI does Automatic Transmission upgrades for 370zs? I don't know about it haha.

I'm getting my car tuned by someone else. I trust him and although I know seb is the man to go to for 370z tunes, I want to give this person I have been talking to for a while now a try.

I don't doubt his work at all, I know it is superb, but that does not mean I can't find a close or equally close tuner xD Plus the tuner I am talking to is close to me which helps!

I'm also not going to send my vehicle to Level10, I will buy their transmission package and they will send it to my aftermarket mechanic shop I am currently working with to install it.

Just trying to help you out from as I've learned from my mistakes and few friend's mistakes on their 370Z builds.

I also wanted to give a chance to this new tuner in my area only to be out of $1000 and having a shitty tune that might of ultimately killed my engine.

My friend had his Level 10 transmission fail at just over 500whp and less than a month of driving.. They also recommended no transmission cooler as their trans is "bulletproof" and here he is without a driving car.

Fast intentions does build transmissions and their reputation proceeds them.
"https://www.youtube.com/watch?v=L3Zqz_3LPpg"

I've learned that cutting corners will cost you way more in the long run. Just do it right the first time with the right shop and you will be better off in the long run :)

:( I just gave FI a call and asked about their 7 AT rebuilds...he said they only do that WITH their Twin Turbo package. If not, then they won't do it. They contract out to a local shop to do it for them but ONLY WITH their TT package.

So he recommended me to level 10 straight away lol, I was like uhhh...sir I heard people saying horror stories come from there but he said nah they for one, order the Flex Billet Plates from FI at times, and two, they are the best around as far as he knows when it comes to Automatic Transmission rebuilds.

I told him oh okay well they also send out the parts to the customer if they wanted to and they can either put it in themselves or have a professional aftermarket shop install it.

He said he was very surprised that they even do that because even FI said they will not touch in putting in transmissions for cars because he said too many things could go wrong.

Your tuner probably didn't have a masters' in Computer Science and prooobably wasn't titled a Master Tuner from ECUtek, haha or was he? O_O
My tuner is giving me 200% support and is willing to drive to my area (about an hour away for him) to tune the car, fine tune it, and make it close to perfect after we get the vehicle running.

He wants me to data log it weekly for him so we can fine-tune it over time.
Also he has a Masters' in Computer Science & just recently became a Master Tuner by ECUtek.

He takes a ton of pride in his customers and even though he is new to the tuning world, I have ton of faith that he will do really well with how he treats his customers (me being one of them), xD

I can always ask Seb for a 2nd opinion if anything as well since I know he is pretty much 6 hours away from me (driving). I'm in good hands both ways :D

cupcakez 04-02-2018 12:37 PM

*2nd Update Today* -- Informational!!!

So I gave Vortech a call asking if they upgrade the SCi blowers the same way 928 does.
They said the cost to upgrade the SCi to an SC is $306. You pay at the end, a lady will call you and ask for your payment information and you pay over the phone that way.
The upgrade that they service to is to replace the impeller with a better one that makes it a v3 SC blower.

I asked if they would take 928 parts and upgrade the blower that way with 928 parts but they said no -- that they only will do it with their parts only. I asked why, and he said because if the blower fails they don't want that to happen, I said well that would be the customer's fault and the customer's discretion as to them asking you guys to put it in or not.

Makes you kind of wonder are they only doing things for customers only or do they care about helping others at the same time? I mean, if I was a business, I would install it for them if they wish, as long as they sign something saying anything that goes wrong is not their fault afterward lol.

As for 928Motorsports, I read a full thread that had Car (The owner of 928) defend his company against someone who was crap talking them because he believed that they messed up his blower. So someone told Carl about the thread and how he was maliciously attacking 928, and Carl joined in and defended him and his company very well.
He asked if the guy could send in his blower to have 928 look at it to see the actual causes but all the guy would show is an ebay listing of pictures and how bad the blower parts looked lol.

Long story short -- he would refuse to send it to them for whatever reason which makes you wonder he probably has something to hide and is not willing to give into whatever that may be.

I want to send in my blower to 928 over Vortech because I trust Carl based on what I have researched and read. I believe they firmly stand behind their work and also some of the highest WHP supercharged Z's on this forum have had their blowers done by 928.

So in saying that, the cost of 928 is:
$1229 Base Pay + $36 Shipping + $30 additional optional rush order fee = $1295 USD.
The turn around time is about 2 weeks from the day the customer ships it and to the day it gets back to the customer.

I will give them a shot and send in my blower sometime next week (Probably Wed or Thursday) and hopefully get it back before May hits so it could be coming in at roughly the same time my engine does.

I will definitely keep you all updated on my journey and continuously upgrade the timeline as well.

================================================== ================
*Update 3 for Today*
I updated the OP regarding my tuner. It has all of his contact information on there and a bit of background information on him.
He isn't well known but I believe he is a very strong tuner and he has some unique qualities about him that made me give him a shot.
Originally I was set in stone going to Seb for my tune but I decided to give Eugene a shot and see how things go from there.
Seb has an excellent reputation already, and I know that I am in good hands with him if I went to him, however I decided to try someone who isn't very well known but whose customer service & support caught my attention (on top of the fact that he is 1 hour away from me and willing to visit me...to tune it which is unique IMO).

He does know a lot about 370z and Infiniti, and all about auto mechanical engineering and the ins and outs of why this and why that. Sometimes the information he provides to me is over the top of my head but I still try my best to understand, as one of his unique qualities is to educate his customers as best as possible about the tuning which I think a lot of tuners in the US don't do.

turtle64b 04-03-2018 06:24 PM

Hey, before you send it off to them, maybe look at trading it in to Vortech for the V-7! It can spin faster and push more flow than stock. Sure it can't spin as fast as theoretically possible with the 928 build, but you get more flow with the safety net of Vortech's warranty on their work. Just a thought!

Also, get an oil cooler!!!! haha

I picked up a 34-row relatively cheap and oil temps are great!

cupcakez 04-03-2018 06:57 PM

Where did you and how much was your 34 row cooler

If I get a v7 I cant use topz a2a kit. Means either I sell it to someone or, not lol.
Also, It isnt within my budget yet to get a v7 :)
As much as I want to, unless the trade in value is not a lot and within like 1500 usd + the blower itself, i wont get a v7. or i can sell the a2a kit get 1500 back and trade in blower still be willing to spend 1500 that was gna go toward 928, that is also a possibility.

Does vortech do trade ins...? I only have about 6k miles on the SC lmao

I think they dont take v3 SCi superchargers that I can find...it only takes v1s it looks like and v2s?

Maybe Im tripping lol, I may call them and ask.

Also, you said the 928 upgrade is theoretically better than a v7 ysi? no way haha I would think the v7 ysi is better than the v3 sci 928 premium upgrade no? or am i tripping again lol

milkcow500 04-04-2018 10:18 AM

So I'm actually swapping out my v3 for a V7 in the next week or two. Here's some things I learned from all my research.

Be very careful when listening to info provided by these supercharger companies. It's a very small market and it seems like they all like to keep things to themselves. I've had Vortech, 928, and Superchargerrebuilds all trash talk each other, which didn't give me much confidence in the industry in general.

Vortech is only interested in selling new units or doing trade ins, which is not worth it imo. I've seen harsh mixed reviews on both 928 and SCR, so I can see how it's difficult for people to decide where to send their business. To be frank, rebuilding a supercharger is not difficult. There's even full PDF guides in how to rebuild a V3/V7 you can get off other forums.

You can use the V7 with Topgunz's kit. You will need to use a different filter though, since there's less clearance and it has a larger volute (4" vs 3.5"). Here's the deal with the V3 vs V7. You want to pick which blower will suite your power needs (For efficiency sake). If you are finalizing on somewhere around Evan's power range, then a built V3 will be much better suited. You'll also have better power under the curve. Reliability issues start becoming a coin flip once you start overspinning the blower though, so keep this in mind. This is mainly because of the closed loop setup and the oil slinger being fragile. The V7 does not utilize an oil slinger.

Buy used and private sell your V3 if you are looking go this route. I bought a slightly damaged V7 for a fraction of the cost of the blower NIB. Play the waiting game and pick up a good deal. Lurk around on ebay and the mustang/corvette forums.

Best of luck.

Be very careful when listening to info provided by these supercharger companies. It's a very small market and it seems like they all like to keep things to themselves. I've had Vortech, 928, and Superchargerrebuilds all trash talk each other, which didn't give me much confidence in the industry in general.

Vortech is only interested in selling new units or doing trade ins, which is not worth it imo. I've seen harsh mixed reviews on both 928 and SCR, so I can see how it's difficult for people to decide where to send their business. To be frank, rebuilding a supercharger is not difficult. There's even full PDF guides in how to rebuild a V3/V7 you can get off other forums.

You can use the V7 with Topgunz's kit. You will need to use a different filter though, since there's less clearance and it has a larger volute (4" vs 3.5"). Here's the deal with the V3 vs V7. You want to pick which blower will suite your power needs (For efficiency sake). If you are finalizing on somewhere around Evan's power range, then a built V3 will be much better suited. You'll also have better power under the curve. Reliability issues start becoming a coin flip once you start overspinning the blower though, so keep this in mind.

Thanks so much for your feedback!
I just found a shop right now saying they are willing to take on the job to rebuild the v3 sci for me as long as I can provide them with the parts and the isolated head unit.

I told him its from 928motorsports and I am looking for a shop to replace the bearings and impeller with upgraded ones.

He says he never done a supercharger rebuild before because his shop does turbo rebuilds, not superchargers.
He said if I can provide him with the PDF file for help and the parts from 928 as well as the head unit itself, he is willing to take on the job.

He does not know the price to charge as he needs to look it up in the service manual for prices lol.

Now I have 2 choices:
1) Purchase 928 upgrade package and have them ship it to me, and I give it to this shop to rebuild.

2) Send in the headunit straight to 928 have them rebuild it and send it back.

What to do....
I would assume he is more than capable of doing it because he is experienced in rebuilding turbochargers.
.and said superchargers are much more simpler.

What do you guys think? Ideas?

milkcow500 04-04-2018 01:29 PM

If he has a good rep and knows how to rebuild a turbo, then he should have no issues.

I know there's a pdf floating around for the V3, but I don't remember where it is. You can have him refer to this one in the meantime: http://www.starrland.com/supercharge...%202-22-08.pdf

If I get a v7 I cant use topz a2a kit. Means either I sell it to someone or, not lol.
Also, It isnt within my budget yet to get a v7 :)
As much as I want to, unless the trade in value is not a lot and within like 1500 usd + the blower itself, i wont get a v7. or i can sell the a2a kit get 1500 back and trade in blower still be willing to spend 1500 that was gna go toward 928, that is also a possibility.

Does vortech do trade ins...? I only have about 6k miles on the SC lmao

I think they dont take v3 SCi superchargers that I can find...it only takes v1s it looks like and v2s?

Maybe Im tripping lol, I may call them and ask.

Also, you said the 928 upgrade is theoretically better than a v7 ysi? no way haha I would think the v7 ysi is better than the v3 sci 928 premium upgrade no? or am i tripping again lol

I got my oil cooler from a guy who bought it and then sold his car or something before he could put it on for $500 shipped.

I don't know about trading the V3 in, but it may be worth the phone call.

I said that the V3 with the 928 upgrade could spin faster than the V7 but the flow rate from the V7 was more.

milkcow500 04-04-2018 04:03 PM

Vortech will give you $500-$1000 credit for a trade in, which is a joke. I literally asked them for an impeller and O-Rings and they told me that my unit needs "major repair" and is not worth keeping. :roflpuke2:

Frozenboost sells oil coolers for dirt cheap btw if you want to piece one together yourself.

So pretty much its like the situation with the v3/v7 head units vs the C38R coming out?

efficiency vs flow rate...hmm...

makes me think should i also invest in the c38r or not haha

rsingher 04-09-2018 09:35 PM

Thanks greatly for the pulley Upgrades ideas and thank you to TopGunz for the 928 recommendation upgrade also. That is just so wild about the car breaking down on your sisters birthday, sometimes the world works in strange ways haha. I greatly appreciate all the help and I'm very soon going to pull the trigger on the air to air kit along with the 1050 injectors after looking so deeply into it and gaining some better understanding of it all. I will document the process as much as I can.

Also, I totally agree on your path of doing everything before adding power. That is exactly what I have done also for the past 3 years of the car. Everything even to the fly wheel and clutch have been upgraded so I figured, I might as well squeeze a little more out of the Stillen kit with the proven adaptations that we are seeing now.

I hope to hear and see more of your z's progress soon here to come!
Best,
Rajvir

You right huh.... I didn't notice that til you said that xD
Noooo I'm not that crazy!
I just can't decide which one to get after maxing out the V3 SCi ... x_X

IPP Stage IV Update:

I messaged Kyle and he said they just got the custom pistons in last week! (11.0:1 CR)

He will go to the machine shop tomorrow and see what's up -- try to get a firm ETA on it for me and then let me know, and then I will let /you/ guys know! :D

Super excited. Getting closer!

Also, I have a mobile mechanic that is going to rebuild the supercharger for me this coming Friday using the 928 parts (Impeller & Seals / Bearings) that I ordered from 928motorsports.

I did not know there is instructions for installing and rebuilding it.

https://928motorsports.com/installpd...on_Vortech.pdf

https://928motorsports.com/installpd...ealinstall.pdf

- It has torque specs and everything which is super helpful.

Hope your stage 3 long block lasts longer than mine did. Mine failed after 700 miles.

You should still have it under warranty unless you drove 700 miles in more than a year.

Did you talk to Kyle about the warranty and it being covered?

And how long ago was it that your Stage 3 blew out?

Depends who you ask. He says a foreign object made it's way into the cylinder, everyone else (including the machine shop it's at currently) says it was an issue with the valves/valve guides. Kyle chose not to warranty the motor, and wanted to charge me $2500 plus a new cylinder head to repair it. This happened a couple months ago and I am now looking to get it repaired locally. The car ran for 3 weeks under the break in instructions before failing. Never saw boost or even 4500 RPM.

So I ended up changing it to a stage 4. I just forgot to edit it. I will edit it shortly.
Thats weird how he chose not to warranty it. Is there a reason why he said no?
Did he say to send it in and they can look at it or ?

I decided to source my block today from RJM.
I just purchased a bare closed deck short block with an added crank and a set of VVEL Heads 370z.
They will ship it by the end of this week to Kyles' shop and assemble it probably and hopefully next week.

I think its going to go well. Its closed deck so it will be strong. They say closed decks can hold up to 40+ psi and is for boosted applications.

The thing about IPP is that all the blocks they build are open. Therefore it is prone to fail if on a boosted application.

RJM told me they have had 5 IPP blocks sent to them for rebuilding in the past 6 months. That scared the crap out of me so I decided to go with a closed deck last second lol.

And I trust RJM because they make sick stuff lately lol.
Successful. Stuff.

Yeah I had it sent to him for inspection and he denied it. Piece of **** motor.
No warranty. 5 in 6 months huh? I wonder if he's ever honored a warranty lol. Hope yours lasts longer. The issue was with the valves, not the bottom end, so a stronger block wouldn't have saved it.

Thanks man. I hope itll go well too.
Hopefully I dont have a valve issue.
And im pretty sure a 3 vs 5 angle valve job is no visible difference haha

No hate but I hope to hell they are'nt doing your block next week. I've been waiting 8 weeks already and was told the delay was with work orders from winter projects. It is noteworthy though that RJM said they've had 5 blocks sent to them in 6 weeks. Either way I've already spent the near 10k on the motor and if it pops at 18psi for any reason I'll just get a new one , however I'd never let a chance slide by to state the facts. They way I see it a warranty on an item like this is something that you'll either get freely or you have to argue for it. I view it like arguing with a cook that your soup tastes bad and then demanding another bowl. I learned years ago in a Wendy's drive through that that's a bad idea. I complained about what was on a Bacon double cheeseburger from the drive through. The manager offered a new burger which I accepted and went home without checking. Get home and just for grins pulled the bun off to look. There was about 9 inches of hair weave curled up under all the mayonaise . Chalked it up to education and made 3 tasty and delicious PBJ's. These engine packages are all about faith. Trusting that there's a valve job, trusting there are JWT cams and they're C2's and not C1's. Trusting that the pistons are really 10:1 like I ordered and not 9:1 standard cuts or OEM 11:1. In cases like this Trust but verify is a bit awkward and I've heard the stories , but for myself I'll have faith until my faith is demonstrated to be bad judgement.

They actually shipped my closed block with added crank and set of heads earlier this week. Not sure why they are holding your engine off for 8 weeks that is more than ridiculous.

I understand your logic. It really does come down to trust that a shop will hold their word to what you purchase.

However, because I ordered a Stage IV, I believe that had a big hand in an incentive to treat the custom built engine (IPP) to the utmost highest. Their name stands behind it, and I am sure they get very few orders of Stage IV's compared to the Stages 1 - 3.

An example is that when he had a core, they said that the core they got had damage to the crank -- and he would not use any core less than 100% for rebuilding the spec 4 block.

I thought to myself -- Does that mean they skimp out on their work usually?
Oh wait, of course. They are a business, every business will take the opportunity and consider skimping out on quality of work and pieces if they can. But I see it as because I ordered a stage 4, they are treating it like an engine of their own and not just "any other customers' order"

But yeah.
It was shipped to Texas 2 days ago and hopefully will arrive tomorrow or this coming Friday at the very latest.

I get ya with the bespoke treatment for the stage 4, but keep in mind I know someone here in Orlando that had the same timeline as me with a stage 4. He got his already and so far I have'nt heard any problems. I just went with the stage 2 and added 10:1 pistons and Cosworth head gaskets. My aim is 700rwhp and done.

cupcakez 05-03-2018 05:26 PM

Lol !! Nooooooo I was refering to being a bit shook when you said RJM told you they had 5 IPP blocks that were blown. I thought about getting a closed deck early on but I would've probably went with one of theirs if that was the case. I took a bit of inspiration from Diabels build except I went with a 6466 and don['t have an itch to run ethanol. If I went closed block I would've probably went with the 6780 and E85 and more interested in touching on 800rwhp. My focus now is to hurry up and get this done so I can flip a coin on doing a DPF delete on my Titan XD.

xD! Gotcha. Well I decided to go with the RJM block and send it to IPP to assemble and machine a Spec IV IPP block.
I really hope it will last longer than I think it will, and it will serve me very well.

Update on it:
- Kyle from IPP received the closed deck short bare block + added crank and set of heads.

- I sent it to the office building of IPP rather than directly to the machine shop lol so a couple days delayed it from being started on. I suspect they will start the assembly and machine work for it this coming week, hopefully finish it by Friday and have it shipped out to my area in CA by the following Friday or at the very least, Monday the 14th of May.

- ITS GETTING CLOSER AND IM SUPER EXCITED. I THINK THIS ENGINE IS A WASTE FOR THE SUPERCHARGER BUT OH WELL. AT LEAST A ROD WON'T GET BLOWN OUT AGAIN.
