I'm putting in a zc motor into my `91 crx dx, basic setup, integra ecu, 2.25" exauhst, intake, better cams, 88 crx si tranny. Another question if anyone knows, put my new clutch on and put transmission on. I decided to test it out by spinning crank and pulling up on clutch lever, axels still move! There isn't alot of resistence there either. Everything lined up ok and I'm sure its the right clutch and flywheel.
