Larry I hate to bug you with too many questions, but youre the only guy I know that will probably have the answers. I have a 2002 8.1 that is going in my 88 R30. I do have to pass emission here in Boulder County. I talked to Air Care COlorado about the swap and all they could tell me is I have to have all the emissions equipment the vehicle came with for that year.The vehicle would get a waiver and have to pass for that years standards. Being that I am going to have a stock computer to do emissions with and another with the howell tune, it should pass with flying colors. This engine should have an EGR on it, but the block off plate on it sure looks like a factory unit to me. My question is, how would anyone tell if it was a 2006 or a 2002? I will install cats on it, but not sure if I should do EGR even though it has a factory looking block off plate.
