20 VALVE 4WD what? u lucky thing! that will go mad turboed, but with fwd it will just spin, but i guess it all depends on how much boost. i was looking at runing about 8.5-1 compresion with a little sc or turbo, thats a big change from 10.5-1 i was led to beleive that drooln ran a turbo on his 20v with 10.5-1 compresion, later blowing only the turbo??????
