i all ready have a DOCH ZC engine in my CRX but it's got about 200000 k's on it and i feel that something is wrong with the engine it's got less power. haven't checked the oil pressure and stuff. but a friend thinks that one of the pistons doesn't have enough compression.

the D15B has low k's on it. and it'll cost about $200 for the engine.

which one you gays recommend now.
