Thread: 06 Grand Prix GT engine swap question

I have an 06 GP GT with the 3800 Series 3 Supercharged engine that is knocking bad. I was wondering if I can swap in another 3800 motor that is not supercharged without much hassle? I have an 08 Lucerne that was hit in the rear. The Grand Prix has a 4 in the 8th slot on the Vin.

I am wondering if the swap would work without swapping the computer and wiring harness over or if both need to come too. Or if the transmissions are different too.

In short. Can I drop a non supercharged 3800 in my 06 Grand Prix that is supercharged with or without a lot of hassle?

Thank you for any help or answers.

Would the computers match up or would they need to swap too?

Nice. So an easy Saturday next weekend.

Thank you so much!

Another question.

Same 06 Grand Prix. A guy at work said he had a 99 Bonneville with a 3800 Supercharged engine. He pulled the motor and was going to drop it in a Fiero but didnt want the headache of rewiring the car.
He said something about the 99 3800 being shorter and skinnier. Would that engine be able to be swapped in without to much hassle?
