My friend has a 300z, and he says he can tune up the turbos with ECU to get his hp from 270 to 500... is that possible?

if by "tune up turbos" he means get new turbos, injectors and intercoolers... then yes

With the Jim wolf "Stage 3" kit you get a cat-back exhaust, an intake, an upgraded ECU and a set of bost jets which will raise the boost from 9 psi to around 14. This supposedly gives around 400 flywheel horsepower. However, most "Stage 3" Zs dyno around 315 hp +- 15 hp, which leads me to believe that the crank hp #s are a little lower than jwt estimates.

But, these mods should get him around 385 hp at the engine.

500???

My wife has a 94 300zx with the JWT ECU, exhausts, sport 500 turbos, upgraded intercoolers, Greddy Profec and VPC and makes 408 RWHP with stock fuel injectors. Stock injectors are maxed right there!!

Re: 500???

Stock injectors are maxed right there!!

So get some 740cc injectors from JWT and turn the boost up!
