Isayimandrew's Twin Turbo Build

isayimandrew

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.

Spooler

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.

For money get a cjm and be done with it

isayimandrew

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

gbrettin

Yes because the intake pipes come from the front.

isayimandrew

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.

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.

Spooler

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

Elmo370z

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

isayimandrew

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.

Spooler

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

Spooler

You can always do this.

isayimandrew

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
