Hey, all. I'm working on swapping my wagon, and have found most of the answers here. Just a couple questions: My donor motor has an EGR valve, but the '92 teg I'm pulling it from has no egr plug on the harness. Obviously not the OE engine, right? What year/engine started EGR? I pulled a spare harness from another '92 teg...it has EGR... what gives? The donor car ran fine, no CEL, so I guess I can just block off the manifold, right? Just wondering how to ID the engine and/or head, can you tell by serial number? The other question: can anyone recommend a header, or tell me if performance will be noticeably different from the stock exhaust? thanks!
