depends on which one but most of them are poop without a k20 head except for the tsx motor the k24a2 which puts out 200-205 at the crank but its got some torque at about 165 ft lbs
k20a (Type R) puts out 212-222hp depending on which car its in
k20a2 ('02-'04 RSX Type S) 200hp
k20z1 ('05-'06 Type S) 207hp
k20z3 (Civic Si) 197hp
but k24 and k20 head is like the b series ls/vtec to a certain extent
