Update: (Last safety upgrade of 2019 - 2020, I swear!)

Now that my vehicle is running how it's supposed to be, I decided it's finally time to upgrade the fuel system and components.

Towards the end of December, I will be having installed on the vehicle the following:

(1) CJM S1-S Return Fuel System (No Rails, because I don't need them at the moment)

(2) Zeitronix ECA-2 Flex Fuel Kit & Gauge

(3) CJM Top Billet Hat to replace the plastic hat that we all know fails at some point

(4) 525lph Walbro Fuel Pump

(5) Hardwire (Relay Kit) for the 525lph Walbro Fuel Pump so that the stock wires do not melt due to this running much hotter!

Before, I had no need for a bigger fuel pump / upgrade in fuel system because my vehicle was only running 6.5 - 7.5 psi max. At the same time, I had the stock 255lph walbro fuel pump from the stock Stillen Kit and had only upgraded to 1050x IDs.

Now, I'd like to finally make the swap to E85 and will be doing so at the end of December when my friend is able to help with the install (The only one that's been fixing all the issues that other shops and people have caused on my car). And yes, he will be the only one touching my car from now on when it comes to installs and repairs.

To help myself from spending money in 2020, I asked him to refuse every request no matter what regarding upgrading my car, and since he is the only person that I'll allow work on my car...well I'm kind of stuck at that point! Which is a good thing for me xD

I also told him to please only work on my car if its any of the following:
(1) Safety hardware change on the car where, if I don't have it, it is unsafe to drive out of my garage / street.

(2) Maintenance (If anything breaks down that causes the car to not run properly anymore as it should)

Any other reason, I told him to refuse it! So I can help myself to pay things off in 2020 while enjoying the vehicle being run as it should without any risks. And no, I do not drive it hard every single time, once in a while I will. Just knowing that it is capable of going up to X WHP and Y WTQ and Z PSI assuming I wanted to push it, is good enough for me! Before, it was never running how it should be as you all know, but now it is and that's all I really wanted -- and that's what I finally got!

One of the main reasons why I'm doing the Fuel Upgrades is because now my car is making 12 - 13 PSI (almost double what I was maxing out in the last 9 months of driving it), so therefore I'm not trying to explode my block due to lack of fuel and incorrect AFR's so, to compensate it, I upgrade the fuel components for the rare time(s) I will push it to the max for fun once in a while!

I have already budgeted everything out in 2020 and how I will pay things off each throughout the entire 12 months. So I'm ready to go! This is assuming, of course, nothing unfortunate occurs and something goes right in my car-journey and physical-life for once!

-- PS: The only thing I may buy is Topgunz new development of the air filter, because I absolutely hate removing this current K&N air filter, but that's only if I need to! XD --

Cupz this is the best way to do it I have several moth this this package and the car is dream, but I am only in the 515 Whp due my Tranny is 7AT stock and all engine stock.https://uploads.tapatalk-cdn.com/201...d122759c5b.jpg https://uploads.tapatalk-cdn.com/201...cccb132fc9.jpg

Did you mean to do the fuel upgrades is a best way to go about the car to run safely with higher power

Or...You mean to buy your car instead / buy a car that's already upgraded or were you meaning something else?
Haha, not sure what you meant honestly! My engine isn't stock but if it was stock I'd take off the air filter and put in a turbo guard like most people do to make more power. Just my block isn't worth risking to take off the air filter for a turbo guard or anything for more power / PSI. Also yeah, I'm also 7 AT, so I'm realistically probably never going to reach 700 RWHP on a dyno sheet or any logged numbers since, I never want to risk my block!
But, knowing that if I take off the air filter, it would reach nearly 700 rwhp would be good enough for me. Potential to drive it if I take something off versus not being able to reach that are two different things for me xD

But yeah, appreciate the post and input!!

Gotcha! Thanks for the clarification! Yeah. I had Charles help me pick out the correct fuel system components after telling him what my end goals were. He did mention the CJM S1-SE system but I figured I didn't actually really need the rails, ever, for my build as I believe (from research and talking to other Z owners who are massively upgraded) that rails are needed from 700 RWHP - 800 RWHP++.

I can always add the rails later on as well, so that's a good peace of mind to know.

So I decided to get the 525lph, CJM-S1-S, Hardwire Relay Kit so the OEM wires don't melt and the billet hat so that I don't have to worry about the plastic hat melting / breaking / failing on me later on.

Appreciate the feedback and support! :D

Seb told me hes at 900whp with stock rails lol i just bought all the fittings and hose to delete the metal hardpipe fuel rail inlet, its going to be sweet!

Update:

- Scheduled to have the E85 Flex Fuel Kit & CJM S1-E, as well as relay kit (so wires don't melt), 525lph fuel pump, and CJM Billet top hat installed this Friday.

- Scheduled to have it DYNO-TUNED for the first time ever with the e85 the next day (21st of December) by Eugene (ByThaBay forum user).

Going to have some serious power gains! Can't wait to see the numbers on a finally working vehicle after 2 years of disasters!

Stay tuned folks!!

Sad Update:

- Last night, the bottom end of the Stave IV rebuilt IPP engine started to give out for unknown reasons at the moment.

- Decided after much, that enough is enough with me and this engine's problems -- so I talked with Adel and gave him the option to take my engine in the current state in exchange for a stock engine (2014, 19k miles for $800 before taxes / shipping) swapped ALONG with all of the current add-ons I have on the IPP block into my car.

- He will be doing the labor to swap everything over to the stock engine and put that into my car, since he agreed to take this offer.

Since he is willing to deal with the engine and take care of it and fix it (whatever may be wrong with it), then he can reap the rewards of a potentially heavily built performance engine.

Let's be honest: I don't need a built engine. Never have. Reason why I bought this rebuilt engine was because Nissan had offered me a REMANUFACTURED stock engine installed into my 2015 Red Z back in 2018 February for $8000.

At first I was about to take that deal since I was in a bind and needed a car for work, but decided against it and cancelled the order (as I hadn't paid for it at the time). So I decided for that amount of money I might as well go for a rebuilt engine...I mean who wouldn't in that case?

I had no intention of getting a rebuilt engine until the very last thing of my build but I was forced to replace the engine somehow due to the stillen canned tune destroying my stock 2015 engine within 5 - 6 months of hard driving it. I also don't need a rebuilt performance engine for my end game power goals anyways) as you have all seen already; there are plenty stock blocks making 700rwhp+ safely. I'm also supercharged, so there's no reason to have a way overkill of a performance engine if I'm not ever going to use that potential to the fullest.

It's honestly better in someone like Adel's hands who has the knowledge, skills and perseverance to deal with any and all mechanical issues that come his way and who has a turbo car that can make use of a high performance engine such as this one -- where as I do not.

It's hard to pin point what the cause is, but we will drain the oil and look at the lower oil pan to see if we notice anything of significant information that can lead to what may have caused the issue of whatever is broken / breaking on the bottom end of the engine. There have been many hands on the engine in the past, but none that has opened up the bottom end of the engine or anything like that. I've kept up on the oil maintenance an average of 3k or less every change.

Looking back at the last 2 years, I've made a lot of mistakes via ignorance, lack of knowledge, etc. Through it all, I can say I'm pretty satisfied that I did go through everything that I went through so far -- met a beautiful Z community (you guys), met some really nice people IRL, got introduced to two people in real life who are almost always there for me when I need them despite my endless car issues, etc.

My tuner (ByThaBay) is amazing. He's always been there for me when he could -- going out of his way even just to help me out when he doesn't need to. He gives me knowledge of things I never knew, and teaches me how things work, answers questions about tuning, mechanic issues, etc.

Either way, my decision is final and the engine is now going to Adel to deal with in exchange for a stock 2014 engine being put into my car.
The big difference is only 1 person is touching the installs this time, not 50,000 people. And this 1 person is very trustworthy -- as I trust him with everything when dealing with my car.

Next update to come soon -- regarding the cause of the bottom end giving out.

cupcakez ~~ out.

You really dont have any luck with this do you. Sorry to hear.

Just make sure you now run a conservative tune and inform your tuner about the engine swap. I agree that he is a super helpful guy to deal with!

What do you think happened?

I wish I could tell you. I don't even know where to start to think what happened to it. Too many variations that I can't pick @_@ Too difficult to pin point where the cause is since so many things has happened to the vehicle in the last 2 years that ... well. I lost count lol

All I care about is a running engine (built or not, I don't give a damn) that runs as close as I can get to 700 RWHP WITH an air filter (current KN conical air filter or topgunz upgraded air filter, whatever one, doesn't matter to me).

All I ask for is one thing:
(1) Safely running engine that won't blow on me no matter how hard I push the thing with my current FI set up at 13 psi with e85 as as daily driver
(2) That the above /said/ engine will hold safely 600 - 700 RWHP as an end goal without breaking.

I will properly maintain the engine doing frequent oil changes, raise the damn car so I stop scraping and putting my bottom parts of the car in danger, and I will even keep the engine bay clean.

Money is not a factor for me as long as I know I can have a safe running fast car with the above specs (to me, it's fast). I will happily pay off my bills for an entire year or even 1.5 years if it takes that long if I am able to have the 2 things I ask for.

I am really happy to hear that honestly. I mean I've seen plenty of stock engines hold up that are dailies that run 600 - 700 rwhp safely. And even driven hard more often than not too.

Especially that 831rwhp stock engine..lol. Gives me tons of hope.

I'll be using e85, having proper tuning, and I will definitely have oil changes every 3k miles or less for regular maintenance up keep. So it sounds like after the engines in by wed of next week (before new years is adels goal) I should be good to go lol.

Let's hope my luck doesnt get worse

Wow. You good sir are a glutton for punishment. Good luck with the next iteration.

If your going to dd your Z, I'd not suggest going overboard (pushing stock motor beyond 650whp) no matter what (for longevity sake). Just my two cents.
