Default Is it possible to swap a 98 motor/trans to 97?

Is it possible to swap a Non Supercharged SE 98 motor and transmission to a 97 Non Supercharged SE? The only thing I see being different is the shifter, in the 98 its on the dash like a lever and in the 97 its a floor shifter.

i think if you swap the PCM over to the car, it should be ok.
Please correct me if im wrong

The swap is with motor and transmission from a 98 into a 97. If you swap them both together, including the PCM, then it should work. I don't believe there is any difference with the mounts or the cradle that would prevent this swap. Right?

There'll be a difference when you got to get tested for emissions and it says the vin is wrong.

I didn't put a 98 into my 97 BTW.

On the engine... overall it'* the same motor. The evap soleniods changed sightly but can be swapped over eaiily.

On the trans, you'd want to look into gear ratio etc.

We could do the swap with the wiring harness and pcm from the 98. There only one wire to move at the firewall. Other than that, it would come up on any scanners as a 98.

Column vs floor shifter isn't anything to be concerned with.. it all bolts to the trans the same way.

I'm usually available if you want a hand.
