ya...there really are alot of sick 4 cyl's, josh pointed out a good one in the B18C5, however, im gonna go with the F20 (or F22, whatever the one in the latest s2 is)...3S's are cool, and can make gobs of power, as do SR20's, but for some reason or other, the 4G just seems to have a small edge....BTW, James from orlando DSM went to the dyno challenge in daytona for the spring break gimmick, dyno'd 426 hp to the wheels in his 6 bolt with a completely blown head gasket and no nitrous....not bad!!
