What kind of power you think I will be making on my 1991 79k VG30E 5spd.Have fidanza flywheel and unorthodox. going to be running around 7psi. custom manifolds nice flow no shar bends. running 370cc injectors with 255lph walbro.

 

What type of exhaust? engine managment? Depending on size of exhaust and how your manifolds are, I would say 240-270whp... just a guess.

 

225whp is my guess.

 

Is that the turbo form the Ebay kit? Should have the potential for decent power, but I don't know why they use such a small compressor housing.

 

If that's the case, I wouldn't even bother........

 

I'm a Maxima newb, but a T3/T4 57trim will make a lot more power than 225rwhp, even at very low boost.

 

For our engines (the VQs), a 57trim with a .50a/r compressor is rather on the small side.

At 7.5lbs of boost, the 225whp estimation from Neal is not far fetched at all. Keep in mind the man has a 91 Maxima with a VG30E, which came stock with 160HP-182WTQ, so take out ~15% drivetrain loss, thats ~136WHP. So yes, that 225whp mark is not unlikely.

 

Not on a VG30E that makes 130whp stock it won't... especially not with those housings. That car is going to make good torque, probably 40-50 more lb-ft of torque than it does horsepower, and then it's going to fall completely on it's face after about 5000rpm. He might make 250whp/300tq if the piping setup is really nice and it's tuned really well and/or he gets a dyno that reads high. I've got some experience with a certain turbo VG30E...

 

Woops, I missed the VG part.. It would be interesting to se how those small Ebay turbo compressor housings hurt power. The turbine side seems fine for low boost and good response.

 

hay guys im new to this but can anyone help me add more power to my max without blowing my engine. ive talked to a guy from stillen about adding more power and he told me not to couse thay made that set up very safe for the max .ok let me run down the list of things i have on it ,supercharger, race pipe,hi flow cat,greddy evo2 and i had the tranny done by level10. dude form stillen got me nurvis about it what else can i do to boost my hp looking to max out what i can do
