if i would use a gsr head and b20 block just bolting it up how much hp would it yield?

if i built the b20 block how much would it yield then? using 11.0 compression pistons and stock bore?

 

165-175 hp

130+ lbs.

 

id say with the head and block you MIGHT see 180 or 190 to the wheels absolutly tuned. Also How do you plan on using 11-1 comp. pistons with stock bore... impossible you're going to have to bore atleast "0.020 over unless you want a shitty motor. With 11-1 expect maybe 210whp about it all depends on what cams, header, head work, bottom end (rods) intake mani - throttle body - fuel system etc etc etc. If you saw the one posted the other day it was fully built putting out about 210whp at i think 155ft-lbs but it has the potential to make 235hp+
