Recently I bought a 98 grand prix gt, well the motor seized up and I have the chance to get a supercharged 3800 from a 2000 gtp, wiring harness and computer for 500. I am just curious to know if I can do this swap with out having to change transmissions and if there is any other reasons why I couldnt do it.

i searched and didnt see any threads right off teh bat.... u will need complete motor... wiring harness and PCM ... trans u have isnt the HD like GTP's have.. it also has different gearing... u would need to get trans tables changed in ur PCM to keep the 3.29 ratio... which can be done cheap and easily.

where would I get that done? the motor Im thinking about getting is complete motor w/ harness and pcm. would it just not shift if i didnt get the pcm changed?

ur final drive gear ratio would be 2.93 anyone with a tuner can do it... look for reptile on here.... he tunes PCM's and can set trans tables for ya. u can still drive the car... but GTP gear ratio sucks.

Yes, the diff is on the passenger side of the transmission...you will also need that axle shaft since it is shorter than the one currently in your car

Would that diff and axel work with current transmission? I really dont want to change the trans, I can get the trans but he wants 700 for motor and trans and Im really trying to only spend the 500 due to budgeting issues.

Yes, that is why I said you need the GTP Diff and Pass. side axle shaft.

Hey dude, just saw you left me a message. Give me a shout when you're ready, and if you can send me your PCM, it's only $50 for the tune.

Sent you a message with my phone # and added you to aim if you can just call me, phone is easiest way of contact for me.Hey dude, just saw you left me a message. Give me a shout when you're ready, and if you can send me your PCM, it's only $50 for the tune.

Turns out after looking at the donor motor today with a fine tooth comb it has a blown head gasket. The search is resumed now.
