anybody know what kind of hp numbers i'll be getting on 12lbs of boost on a stock gsr motor

 

well people on honda tech are sayin 310+ but who knows. well the gsr hold 12lbs safely.??

 

Yes...GSR will hold 12 psi safely depending on tuning.....I wouldn't use an FMU or AFC hack...allthough it might not blow up with the Hack, but it has a lot more chance to blow up with either of them then with a chipped ecu or standalone.
Don't cheap out on a B-series engine...

 

i think that turbo is too small for a gsr.

 

just get a nice tbird turbo or something similar like a .60/.63 and you'll be okay...i wouldnt have such high expectations i would imagine 280 or so at 12 psi...well i guess it all depends on the turbo

 

The 16g would be a good choice for a gsr, you don;t need an enormous turbo, besides the EVO does quite fine job with it.
