@colourfultree,
the aging f20c still superior over a k20ar,
the complete package of a f20c is proven to outruns k20ar, no matter on street/track/touge.

for a fair case, look at their stock delivery on its own default car,
in this case, s2k vs fd2r.
the f20c stands out clearly at any battle on street/track/touge.
fyi, a stock 2l f20c already churns out 240bhp.
not to say a revamped version, f22c on higher torque for corner atk.
