I'm looking to up the power at little in my civic. I've read that putting the B16A2 should be an easy fit in my car, but I noticed that wiring changes are a must due to the change from SOHC to DOHC. This will be my first swap and I'm concerned about any complications about this specific task, especially the emissions since I'm in PA. Can someone please outline the key issues I must watch for and fill me in about passing emissions and anyway around that if need be. Thanks. Any help is much appreciated.
