Okay so long story short I bought a truck with a 22ret and the block/head/turbo(pretty much the whole dam motor lol) was toast. Instead of spending a fortune on 22ret parts. I decided to just drop a 22re in instead. Cheaper to build and the turbo doesn't do all that much any how. I have the turbo efi, I'm wondering is there a difference. I know of course that I'm going to run a different exhaust manifold. I don't know if I would have a problem running the turbo efi on a regular 22re.
