Hi everybody,
I have 04' G35 cope 6mt (forged rods and pistons)
already APS TT (unichip)
+monster test pipes
+skunk2 exhaust 2,5

480 hp at flywheel on dyno

wanna more-what to do?
can unichip increase boost?
in my labor told to me-that aps turbos (garret 2871-too small-and 14,5 psi - is the limit)

wanna more-what to do ???? proffesionals please.......

P.S. please without jokes

 

Buy a boost controller and turn up the boost, and get a re-tune. You can increase power easily that way.

 

+1 you can buy a turbo smart manual boost control for $80-100 and then you will need to get it tuned again. Depending on supporting mods you should be able to make 550-600hp at the wheels with the GT2871s and a built engine.

 

so it is bul.... when I hear from our tuners that garret 2871 turbos are so small-and they cannot do more 480 hp at flywheel

 

I know for sure red35 has GT2871s and he put down 475 wheel horse power with them at 10psi. I have seen others that put down more than that on my350z.com.

 

I have the 530 kit from JWT and I believe these are a GT25 turbo (but JWT changed a lot on it, still a GT25) and I make 477whp at 13psi. With GT28 you should easily get to over 550, one day I'll be upgrading to the JWT 700bb kit which are GT28s and will be hoping for 600whp.

 

First, buy a boost controller. Second, not sure if you have one or not, if not buy a fuel return system (Check CJM). Thirdly, more power means more heat, so invest in a larger radiator and oil cooler, and lastly get a good tune. That's what I would do. All that should get you somewhere between 500 and 600whp.

 

big thanks!!
