Hello, new here! I recently picked up a 99 ex coupe with a mismatched motor, trans, and wiring harness. I really didn't know what I was looking at until I had the car for a bit. I have a y5 block, and I believe the wiring harness is a y 5 also. transmission not sure, and a y8 head jerry wired for vtec to work. I plan to build a y8 or a z6 block this winter to put in for the summer but had a few questions, one of them being If the engine burns oil but not significantly (only in vtec) would I have to bore out the cylinders completely or could I get away with just a hone, new rings, and ar resurfacing?
