My built TT 370z is getting tuned today... What power can I expect?

I upgraded to the GT-R manifold as I've heard horror stories of manifolds starting to bulge and eventually leak when approaching the 20psi+ mark. I just didn't want to have to deal with that happening. Plus it looks cool - lol!

Gotta be getting closer to your turn.....

No way you're reachign 750 on pump. The way it sounds. You need to do some major research before trying to reach your power goals. I don't understand why you want to push the build to it limits. Limits= kaboom either your motor or something else, unless you have endless pockets, then hell yeah. Instead of wasting your money on that manifold you should of invested in a return fuel system, maybe some ID 1700 injectors, maybe a twin pump set up, lsd or clutch ( hoping you already have those upgrades) or add a stronger oil pump or add a baffled oil pan.

Hopefully you made it on the rollers & got a tune,
Should have some decent numbers!

Why did you opted for now on a proper return fuel system? Sure with a good build and proper tune you should be fine but honestly you should have install that fuel return. Rated 720 cc injectors and 320 lph fuel pump plus lowering the compression you will have to push the turbos harder to reach lets say 500whp than someone with 11.1 compression ratio. I lower the compression on mine and i didn't skip on a return fuel system and believe me is harder to reach the numbers you want. Your limiting factor right is what will help you the most achiving what you want....FUEL!

So, longer story my cars been at this shop for 13 months after a lot of ups and downs. The money aspect isn't the problem, I'd just like to have my car back at this point and not wait another however many months. Fuel system upgraded will happen sooner than later.

Clutch was upgraded to one rated for > 800wtq, that shouldn't be a problem. Nismo oil pump used, lsd wasn't upgrade - I've never heard of them being an issue. The car is a nismo so idk if it has a better lsd / better axles than the other models.

Builder / tuner said it probably won't be needed for < 600whp even on 9.5:1 compression.

Honestly I'd get your car out of that shop as soon as possible! 13 months for a tuner who doesn't know anything about 370Z's?

I've built a GTR from the bottom up including a new fuel system, flex fuel, new turbos, engine dismantled to the short block and sent out to be rebuilt, shipped back and assembled by myself and then tuned all within 6 weeks.

Don't make the mistake many others have done and keep it in a shop rotting away. I haven't seen a 13 month build in a while unless it's a completely custom car..

Hopefully this won’t be another case of I told you so. Judging from his comments he knows just as much as his tuner/ builder about the z34 chassis. Darn shame

Elmo370z

Lsd needs to be upgraded if you quote on quote want to make 700whp, or you will learn the hard way when the car sends you onto on coming traffic or a ditch.

“The car is a nismo so idk if it has a better lsd / better axles than the other models” that is what I was referring to about doing some research, my friend you are going down a very expensive road that isn’t for the good.

VSS370z

I would feel more comfortable with a Aeromotive 340lph and 1,000cc injectors and still i wouldn't aim for 600whp without a return fuel system since also lowering your compression you will need more boost than someone with an 11.1 ratio and you will hit a wall with the fuel aspect! Just my opinion

Rusty

You got the same axles as everybody else. As for the VLSD. It's junk. When they get hot. It's the same as an open diff. One wheel peeler.

I know Bob (the owner) and actually talked to him. I would of been happy for him to take on the project. They however do builds from the ground up and didn't want to deal with my existing 1 off turbo kit setup which is understandable since they don't want liability if the car breaks from some part they don't stand behind.
