i am considering putting a d16y8 head gasket and zc pistons on my friends CRX w/ mini me. its a d16a6/z6 mini me. he wants the higher CR to make more power. will this hurt his engine in the long run? the bottom end has 130k mi and the head has very few miles. how much of a power increase should we expect to gain? thanks--david PS and DSM guys out there: is it possible to mate a 16 valve head with a bottom end from an 8 valve from a '94 eclipse?
