I would love to enquire what the challenges will be when swapping from f23z to f22b automatic engines.

 

welcome to the forum. possible items, engine mounting, exhaust system, wire harness, ecu, transmission (need to check for match up). also if you have smog checks like in Ca. going back to earlier year engines may cause for special smog checks.

 

I don't know that anyone here has done that. Maybe you can be the first to write a review.
