700hp twin turbo project
 

Hey guys :hello: Its about time I quit being lazy and do a thread here because I know ill have questions, and hopefully this thread will assist others with their builds in the future.

Anyway, I had the Boosted Performance kit for about a year and a half before my motor blew up:
http://www.the370z.com/forced-induct...0-blew-up.html

I loved every minute of it. After blowing it up I contemplated selling the Z, buying a Prius, and calling myself Caitlin. I did some soul searching and decided to build the Z for 700+ hp instead. To do this I would have needed to purchase a bigger turbo and possibly do a little modifying to the kit. Shortly after coming to this realization, I was offered an opportunity that I couldn't pass up. I spoke with Mike at AAM about making me a custom exhaust and he talked me into switching to the AAM twin turbo kit, along with them making me a 4 inch single exhaust :eekdance: I was offered sponsorship pricing which helped my decision tremendously. I am really honored for the opportunity to participate in their sponsorship program and will be posting a review when this is all completed.

Now for the motor, Im planning to build it myself. Im a big DIY guy, so if this thing goes, I only have myself to blame, and ill likely learn a lot from this experience. I scored a motor with 6,000 miles on it for super cheap, which will be the transplant heart. The engine will have Carrillo rods, 9:1 Wiseco pistons, ARP L19 head studs, ARP main studs (haven't purchased yet), and the usual head work. Ive thought about doing the JWT cam, but I haven't decided yet. I also picked up an ATI Super Damper in a group buy here for cheap.

Next is the machine shop. Funds are the hold up at the moment. After Christmas and a recent vacation, not to mention setting money aside for ZDayZ, my bank account and wife hate me right now. I still hope to have the Z done by ZDayZ though. Anyways, I still need to buy the main studs and send all of my parts over to them so that it all can be properly machined. Im also still waiting on the turbo kit and exhaust from AAM. After that, Ill rip out the old motor and get this new one ready to be put in :tup:

If you have any questions or suggestions, feel free to share them.

Aw, yeah...

Want to build my motor? I'm thinking about putting a Novi 1200 series blower together. Question why run 9:1 pistons? Guys are making that power with higher compression pistons, Im just asking?

I would love to build you a motor! But I wouldn't consider myself a "professional", so I wouldn't trust myself to build motors for other people lol. Just in case something went wrong, I wouldn't want to be the one that screwed up.

I picked 9:1 because I want to reach 700whp on pump gas (93). E85 isn't exactly readily available here. I really wanted to get 10:1 pistons but was afraid I wouldn't be able to hit my goals with that compression.

I can't wait to see the outcome of this one. My wife will probably end up hating you too at the end of all this. It's cool with me though cuz then when we all finally can get us and our wives together, you, me, and Memphis370Z' wives will at least have one thing in common!

This has all been a struggle with my wife lol. She isn't happy at all and will be excited when it's done so I will quit spending money lol. At least our wives will have an ice breaker lol.

Sweet, are you going with the standard 6758s or upgrading to 7163s?

I'll be sticking with the standard 6758's. I almost bit the bullet and upgraded to the 7163's, but the 6758's should easily get me to my 700whp. Even more if e85 makes its way around where I'm at.

In for more details when they come available.

Be sure to use the heavy duty actuators if you are staying with the 6758s because I am limited to 21psi with the medium ones.

:icon18: LIMITED TO :rofl2:

Good to know. This is something that I'll need to purchase separately correctly? Or do these come with the turbos?

I would request it from AAM if you haven't already gotten the kit. The kit comes standard with the medium actuators. I don't believe they cost very much, but are nearly impossible to change when the kit is installed in the car.

Cool, thanks. I'll shoot Mike a text in the morning and ask him about it. My kit and exhaust should be shipping out this week or next week, so I'm sure I still have time to see if they can throw it in there before it heads my way.

Man I can't wait for your build to be done!

Looks like it will be a great build! Sub'd

Nice im currently running the aam kit myself. Made 540whp on 9psi on stock block. Did you get the return fuel system? What clutch are you planning on running? What csc are you going with? I also had them make me a custom exhaust. But mines a custom dual 3 inch.

I have the CJM return already. I also already have the CJM RRP, so I'll do a little more fuel upgrades. Likely run all new fuel lines and do away with the factory lines. I'll have to get with Phunk and pick his brain.

I have an OS Giken twin disk right now. Hopefully that will hold the power. Only one way to find out lol. I have the ZSpeed CSC right now. I might switch over to the Z1 because I'm getting tired of rebuilding my CMC from the fluid draining because I have had to take my transmission out more times that I can remember.

Your exhaust looks awesome man. How does it sound? I can't wait to get my car running again. I have never driven a twin turbo, so I'm really interested to see the difference between a single and twin first hand.

Its going to be pretty hard to hit 700whp with that 9:1 compression on pump gas. I think 10:1 compression is the perfect compression for our cars. I have a built shortblock using 9:1 compression on e70 and making 704 whp and 644lbs of torque. Lower compression will let you boost the hell out of your car though. Fuel system is going to be the biggest challenge. Go big on everything bc you will max things out pretty fast.

Once you get completed and tuned post up your results in the finished builds & I can add you to the list.

Hmm. Now you've got me worried about my compression. I feel like I saw someone here on the forums that got 700 on 9:1 on pump gas but I can't remember exactly. I guess I'll figure out. I really preferred 10:1 over 9:1 so I would have more response.

What kit are you running? I plan on going pretty big on the fuel system. I don't intend on cutting any corners. I'm not sure what size injectors I need to run quite yet. I haven't gotten that far in my planning.

I just got a call from AAM and they said my kit should be shipping today or tomorrow. I also had to order a torque plate for machining my block. My machinist doesn't have one so I picked one up. It will be around 3 weeks before I actually get that. So I need to come up with a time table. ZDayZ is coming up quickly lol.

Hjo is running a Fast Intentions kit. I agree I think your gonna have a hard time getting 700whp on pump gas but that would be awesome if you can hit your goal.

This was on e70 around 23 psi. Im running a fast intentions turbo kit. If u can switch up to 10:1 and u shouldnt have an issue reaching your goals. Your build is very similar to mine. Anyhow im subbed. Good luck bro

Hmm. I may have to do some shopping around...

I was too scared to go over 600whp on pump gas because detonation. I went 10:1 compression for response, but I'm guessing if you go 9.5:1 the difference would be negligible and you could boost a bit more.

This is my final E85 21psi tune with ID1000s at 90%+ IDC with CJM Stage 3 RFS (Twin 255 pumps):
http://i.imgur.com/1yFCSsN.jpg

I'm probably going to switch out to ID1300s sometime soon.

Do it, those injectors are made for e85. My car runs so much better than when i had my asnu 1100 injectors. I havent even popped the p0300 code since switching to them. Didnt change anything but the injectors and a retune and made 50 extra whp and alot more torque.

The kit and exhaust was very well packaged. I was somewhat impressed with the packaging actually lol. The pictures are after I pulled all of the stuff out of the boxes. Now I play the waiting game. I was unable to get to AAM before they shipped the kit, so ill likely order the more heavy duty wastegate actuators later, but before I install the kit.

I run the OS giken twin disk with 800whp and 700ftlbs torque and it hold all of it just fine. The twin disk is very streetable and has given me zero problems at my power level. You should be more than fine Ontop of the fact h already own it I would call it good.
Congrats on the build man and good luck with the wife. Mine hates the cars guts with every fiber of her being and me whenever she hears it fire up :icon17:
Looking forward to good results

tturbo370z, what is your compression ratio on your motor? These guys have me questioning my choice lol.

I did mine 9:1 and this was before I ever new I wanted to do e85. On 91 I'm only good to around 570rw and with e85 we stopped at 800 since the turbo housing was about there anyway. The reasoning for the lower compression i was told was to be able to run the turbos in a better efficiency range. I'm not a builder or car expert but at the time it seemed to make sense. This was just the choice I made at the time with the turbos I'm using. I have wondered myself if I would have been better off on 10:1. I'm not worried about it as I can boost the $&@! Out of it and get however much power I needed. I only wanted 600rw on pump gas and then I fell short so added water meth kit but it only added 100whp so then I ditched the meth and ran e85. Run whatever compression that will allow your turbos to run in the range they are most efficient. I would say that's where u want to be .

Hmm. I may go ahead and switch to 10:1. My issue is that we don't have e85 very close to me. The nearest is about a 45 min drive from me. So I'll mostly be using pump gas (93).

I would love to have e85 within 45 minutes of my house. The closest to me is 110 miles so I got a 55 gallon drum and six 5 gallon gas cans. I make the trip about every other week to three weeks and get fuel. It's an inconvenience but I don't care at all because the payoff is worth it to me. I hate every time I have to use 91 craptane. Granted you get a lot more whp out of 93 than 91 but you will not want to use it again if you go e85. Come on that's like just leaving a 100 whp on the table for no good reason at all other than you scared to get 800whp. :stirthepot:

110 miles. That's dedication to boost right there.

Lol well my unofficial goal is 800 on e85 once I get a station closer to me. Until then it's better for me to use 93. I've thought about getting a 55 gallon barrel or two to keep at the house but I don't know the shelf life on e85. That and I don't have a truck to transport it back and forth. I really wish it was more readily available. You are very dedicated sir lol.

I do have a truck but I don't take the drum because it's to heavy to unload full, so that is why I use the 5 gallon cans. The shelf life is actually pretty damn good storing it in the drum, better than month without any noticeable change and as long as it says above e70 you are good to go, hell anything above e50 is still rockin. I can also have it delivered if I choose for about $4 a gallon right now, but it's actually cheaper for me to go get my own with diesel being less than $2 a gallon and besides there always something I need to get in Las Vegas!

And if you flex fuel...well fixed and done!

Congrats on your build! One question I do have if you get to your unofficial goal of 800 on E85 what are your plans for traction and keeping that power to the ground?

Whatever you do I am sure it will be a blast :tup:

Get the one with wheels and a hand crank pump. Keep that at home and do a barrel in the truck. Just syphon it to the garage one or use a ramp to unload.

But that's still a lot of trouble for something that burns fast.

Well.... I don't really have plans to put 800whp on the ground. That will be more troublesome than I care to deal with. I have no idea why that number is in my head, but that would primarily be for self satisfaction to be a douchebag and say I have 800hp lol.

Lol.. then you will have to get super wide wheels and rubber, SPL parts and make a decision to go straight or be able to take turns. 600+ rwh is Herculian on the streets or track. 700+ is nothing short of Godlike or full retard. It's your pick
