i got a b20b block with a b18c vtec head i was wondering what power i would be making at the flywheel with this setup and if i where to turbo it what do you think i could make at like 8 psi.

 

There is too many factors to say for sure. Is it a stock B20B with a stock GSR head?

 

Stock b20 with stock gsr head with good compression you could be looking at anything from 180-200 whp. Lots of variables in these frankenstein builds. I wouldn't turbo a hybrid like this without a decent build. Also chances are you'd have a problem with the head gasket sealing with extra pressure from boost.

 

stock B20VTEC your looking at 160whp 175 if your lucky. Dont boost it without at least rod bolts
