So - for me I ‘think’ I have come to the conclusion that my current Z is going to be a ‘keeper’ so that being said - FI is always on the mind. Would love for the Z to be a little bit faster etc. While I think the NEW Z is nice as well - with current prices and honestly - really wanting a different platform for a 2nd car - I just want to make my current Z a ‘project car’ which has me asking all these questions when it comes to FI.
Right now - FI is a little more down the road - I’m trying to make all the other pieces etc be a priority vs going FI since I am looking at keeping this car as a ‘keeper/project car’ for the future. IDK - though - but @OP - your build is really really nice and clean. I can’t wait to see what your end result is etc. :)

Biggest thing that can help you is doing your research. FI on a stock block is iffy at beast. It can get expensive quick. I have hurt two built motors. It's not fun.

100% - you are a wealth of knowledge and when you say something CAN/CAN’T be done - I do take note of it. Part of the reason why I think - keep it full bolt-on and look for suspension upgrades - it does make more sense than going FI - hence why I look at FI as the last part of the build as a whole. Bc I know its probably cheaper to go another platform than to try to make a NA motor driven platform into a FI platform vs going with something like a manual Supra or even the new Z so you are starting somewhere cheaper etc.

If you want it to be a track car a suspension and diff upgrade can do wonders. Then time in the seat. FI cars are hard to keep cool on the track. It can be done but it get's expensive quick.

Thanks! this is my "keeper" car too so thats why I decided to dump a bunch of money into it lol

I totally get it; I feel the same way. My plan right now is to keep it FBO and then look at the suspension mods and some ‘minor’ cosmetic mods. Then at that point - hoping to have a 2nd vehicle that will be OEM+ (can never leave a car stock haha); and then probably go down the rabbithole of FI. At least that is the plan.
When it came to the new Z coming out - I was all about it and definitely wanted to get one - but after seeing the reviews have been less than stellar, the fact its more of a GT car than a sports car - I just feel I would rather have my current Z than the new one.

I’ve been following your build on Instagram and on this thread and can’t wait to see the results you get etc. Definitely keep this thread updated :)

Got my final tune finished. Dropped my car off a few weeks ago to get the rest of the parts I had planned to get installed this year and to finish up the final tune for my build.

- Upgraded OEM fuel rails to the radium fuel rails
- Installed RJM clutch pedal with HD MSC
- Installed Chase Bays Windshield Washer Reservoir (since I had to take the stock one out for the intercooler piping)
- 1000 mile maintenance check up (oil change and analysis and double checking everything is still good with the new build)

Final numbers: 760 WHP at 683 WTQ on E85

Real happy with this build! Went in originally wanting 550 WHP so this is pretty much the final as far as performance goes. Next up on my list for the next coming years will be to get my seibon hood painted and installed, get coilovers with some kind of lift system (air cups, KW HLS), some recaro seats, and maybe some other visual stuff.

Congratulations sir

:tup:

Congrats! Maybe I’ll see this thing in the wild someday if I’m lucky.

Ooooo learn something new. Stock ones make brake duct routing inefficient.

Are you part of the Z club of Texas?

No. I did join a DFW Z club long time ago but never attended any car meet. Too busy too lazy too tired.

Yes I am a member! Will you be at the event this weekend?

haha I gotcha. maybe we will cross paths one day

I should be going unless it rains lol

If anyone was curious, here is where I have my chase bays windshield washer reservoir. It's pretty small but has enough to clean my windshield in a pinch.

Doing a bit of research and getting a lot of mixed info (including from previous posts on this forum) on the stock intake manifold limits and had a few questions for some of the more experienced guys:

- I am running 21 psi of boost. saw some posts say anything over 25 psi is where it starts to crack and another post say over 18 psi when to start worrying. Should I be planning on replacing my stock manifold sooner rather than later?

- Are there any reliable options out there that maintain using the stock strut bar? I've only seen AAM and Soho. Pretty much everything I've seen about the AAM is bad from quality to performance. Saw both good and bad reviews on the Soho and on their website its not even available right now. Also saw mixed reviews on using the GTR manifold and that does not maintain the stock strut bar.

I just sold my SOHO one. You may be crap out of luck on that one. At 21psi, the stock intake will crack/split.

You're running the CJM manifold right? Looking at your thread could I even trust Soho if I were able to get one? lol If thats the case, there doesnt seem to be much options since AAM and Soho are the only ones I really see.

The manifold work just fine. That wasn't my problem. I got the CJ Motorsport one because I wanted one for a long long time. The GTR ones you will lose around 70whp.

i have one if you want to buy it (soho)

For money get a cjm and be done with it

Do you (or anyone else) know if you can still put the stock engine cover back on? If I do go the Soho route, I dont really like the look of their design so I would much rather have the functionality of a stronger manifold but cover it back up to look stock.

The CJM manifold requires a lot more changes though right? Its not a direct replacement like the Soho one?

Yes because the intake pipes come from the front.

Anyone have any experience with CNC Innovation? This seems like a nice intake manifold to replace the stock plastic one..

Looks gorgeous, but I don’t see any testing results. I wonder if they have made/sold any, looks like TB locations might be different from stock. Definitely interested to learn more about it.

Oh....that looks nice. :yum: Wonder about testing tho.

If you needed 12 injectors and had a Standalone to run them with the engine holding together that's what you would need.

Looks like you're right. The TB locations are slightly different so not really something I would entertain. I originally thought it was a direct stock replacement.

It’s just paper weight unless you plan on trying to make 1200+whp. It’s cheap just to replace the plastic if it starts leaking. I’ve found cheap as $50

Gotcha. Looks like I'll be going with that approach since there isn't really too many options without either sacrificing quality or performance. I was revisiting this since I was going to do some mods that required a re-tune so I figured I might as well check and see if there are any cool looking options that would also help with reliability.

If you are under 19psi of boost you don't need it. Go to 20psi or above and you will.

You can always do this.

That is what I am worried about. I am right at 20psi. I am going back to get the CJM MAP sensor adapter and going with a 5 bar MAP sensor since I've gone through 3 OMNI 4 bar MAP sensors in a year and a half and the shop that I am using that mainly works on GT-Rs stopped using OMNI on all the builds he does now because of that issue. Since I am re-tuning, I figured I might as well go full 3" downpipes and exhaust which should lower the boost required to make the same power I am running now. Talked to Tony from Fast Intentions and he was thinking I would be able to reduce the psi to 18 or 19 so that might solve my problems?

That intake manifold is so beautiful and I would if I didn't have to do a lot of re-work on relocating and getting new parts for it to work on my build. I was looking for a direct replacement to keep everything I have in place

3in downpipes and exhaust will help. I doubt it drops any boost pressure. I have the CJ Motorsport Motec 5 Bar map sensor on my car. It's worth it. At 20psi it will last a while depending on what boost level you drive it around on everyday.
