I have a 97 base model civic coupe with y7. Engine is currently in pieces for a rebuild. So far the only thing still good on the y7 is the block. I have an a6 bottom end and block, a y8 head, a z6 head. I have a y8 master rebuild kit including y8 pistons. I want to keep the car obd2a for now since I have a p2p ecu I. I need some help trying to figure out what to build here for higher compression and which oil pump to put on this build. I'm opening up the a6 block/y8 head combo motor to check it out today hopefully I see the pm6 pistons. Please help!
