F20c- s2000 , 237 hp, lacking in tuning potential but already pretty highly strung
K20a- dc5 itr, 217 hp, great tuning potential, 240 easily acheivable with bolt ons iVtec really helps
K20a2-ep3, 198 hp, as k20a really but not so good as std,
dc5 best overall package, looks handling and drivability.
