The dakota 4cyl trans is not noted for it's strength. All the serious guys use the dakota bell but bolt it up to a toyota supra trans which happens to bolt up to the dakota bell. A guy is making the adapter plates, and a 2.2/2.5 run the same bolt pattern as a 2.4 with the exception of one bolt being different. You'd have to either skip that bolt or bend up a L bracket if you wanted to run a 2.2/2.5. The 2.4 with it's DOHC makes as much power as a T1 2.2/2.5 anyway, and has more HP potential when you boost it. You could chop up a factory harness out of an 80's turbo mopar to work or run an aftermarket EFI controller. Or if you really want to keep it simple, run a carb 2.2L bolted up to a 904 w/ that adapter plate.
