I just bought a 92 GS-R with the venerable B17A1 engine. I would like to bolt on in the following order: A DC Sports cat-back muffler, an AEM cold Air Intake, a DC 4-1 Header (probably this summer...when the money tree grows) and maybe some other goodies.
My question is..should I do some type of engine re-build on the
11 year old engine with 120K first? What does the re-build involve? Your comments?
