as long as the motor ur swappin in is same year or higher for ur car, then its kewl. make sure u have all the smog stuff hook up accordin to that engine and car diagrams. cat, egr(if any), usdm ecu(if jdm engine) all sensors hook up, o2, ect..., all vacumn hoses connected up. no high flowin fuel pump or modified fuel pressure. make it all stock as possible. aftermarket intakes, make sure its carb ex and have the number visible. use stock header if possible. basically once u get that all so wonderful BAR sticker, its all happiness from then on. i know i am, cuz i got one.
