It's time for a new engine the b16a2 lost compression and i dont feel like rebuilding it. I'm now stuck with my 00 civic si and lookin for a new engine. I want to keep it in the obd2 range, but i have the crap obd2b car. I was just curious to see if that would he a hard swap to accomplish since i have an obd2b harness and want to put a obd2a ITR engine in the car. Can anyone help me out with some pointers that might make the swap easier.
