I have a blown 2.5 EFI (92ish model) with a 1 piece adapted and a 2.4 200 carb motor (89ish model) that I want to use for the mean time. I know they will bolt up but I dont have them apart yet and dont know if there will be any issue with the water passages and also if the tuner will work correctly. I dont want to kill the bottom end torque if the tuner is to open for the 200. If anyone has any input it would be greatly appreciated, I'm all ears.
