The engine in my 1990 Jeep YJ is done...the ECM is no longer available and mine is not repairable, and trust me, I have searched high and low for one. The one or two I have found (used) they want $500 for it with no warranty. I would really like to install the Cummins R2.8 but it has not yet received an executive order. I want it because I think it will be an "easier" swap since there are a lot of packages where I don't have to source parts all over. Since it appears it won't be available here anytime soon, does anyone know of another option with a Chevy V6 or V8 that would be as close to California turnkey as possible? When I search the web, I keep getting all the law related crap and not an actual retailer or shop that could provide this engine. I would like to retain my current Chevy SM420 transmission which is why looking for mostly a Chevy swap.
