07 civic type R vs 07 civic SI
do any one know why the civic type R has 220 HP while the si has 197 it should be the same engine what is the diffrence (is it the ecu) and can add it (what ever it is to the si)
im gonna say better cams, manifolds, higher compression, ecu, hand ported head, things typically done to the type r line of engines
also note, the edm ctr has less hp than the jdm version
