If you still have your turbo car it should be easy breezy. Persay. You will want to use everything from the turbo car. Motor mounts, ECU, fuel pump... etc. If your ECU is indeed damaged look on MR2OC in the for sale section for a used one. Since you have a JDM engine I would try to get a JDM ECU.
Also... you are going to have to pull the entire wiring harness from your turbo and swap it into the NA. That will probably be the most fun part
EDIT: Also... why you still have the turbo car. Pull the front brakes, interior pieces and fog lights that are not on the NA.
