I currently have a 1980 US auto 928. I am going to be pulling the engine out and cleaning it up. There was some issues with it that I want to look after like noisey lifters (tried all the additives and still doesn't go away), TB and WP, and put in a new gasket set since I have various leaks. I will also be changing the Motor mounts and anything else that needs to be done. oh yeah and putting in a new free flow exhaust system. I was wondering since I will have the engine apart if there is anything that I can replace on it with other year 928 parts ie. later model exhaust manifolds, euro cams, throttle body, intake. without having to re-wire anything or do any drastic changes. I am also wanting to supercharge this guy in the future as well.
