Alright, I'm swapping my engine from my 96 into my 01 (piston skirt broke). i have one really big question that is stumping me before I pull the 96 engine. First, I plan on keeping my header from my 96 and eliminating the 2 pre cats. Can I swap my 2001 pcm with a 99-00 pcm to eliminate 2 of the 4 o2 sensors? What are my best options? All responses are greatly appreciated.
