I have a 97 gtp and a 02 gp and i want to swap engines can I do it and what all would I need to change?
Thanks

what motors are in them if you are swapping a 3.1 with a 3.8 you need to swap teh cradles too and teh pcms

Not worth the trouble.

And if you search, all this information is on this website.

[97and02grandprix]

both are 3.8

[gtpeddie]

You will need a 98-02 GTP PCM

The 97 GTP PCM is different

Why would you want to swap engines?

[97and02grandprix]

would it be better to buy a turbo for my 02 then

[gtpeddie]

If you have the money but with a turbo you will destroy the stock transmission

my 02 is a 40th anniversary in better shape

[gtpeddie]

You could top swap it that would be easier IMO rather then going though the hassle of swapping engines

If you plan on a top swap read these first..

They should get you started and get an idea of what to do

ya i could do that the only reason i want to swap engines cuz i would also swap the trannys my 97gtp tranny has a shift kit

Idk I think it depends on how mechanically inclined he is and if he has someone close to him to help him tune the car.

[Slick2500]

The 97 trans wont work in the 02, the valve body is different and the cooler lines are different as well. The cooler lines are easy to fix but the valve body idk.

[gtpeddie]

Shift kits are cheap and easy, trust me its not worth your time to swap the transmissions because of the shift kit

[Fivefingerdeathpunch]

You have a few days of reading ahead of you.

You need to understand that a GT and GTP arent so much alike.

Sure the motors and trans carry the same name, but each are alot different.

GT is 9.4:1 compression and GTP is 8.5:1, GT trans has 3.29 gears, GTP has 2.93's. Both have the same strength, both will die with enough power.

97 GTP PCM is year only and MUST have the wire harness to use it in another car.

You'd be better off top swapping the GT, instead of swapping motor. Whatever you decide on will need a full on custom tune to make anything work.

Dam i thought this would be easier

[Slick2500]

Thats what sucks about having a 97 car, everything is different, trans, pcm, blower, abs, hub bearings, DIC. Its the bastard child of the Grand Prix world. Why everyone says if your looking for a GP go 98-02 because 03's have a some one off parts as well.

[gtpeddie]

I love my 97 GTP

[97and02grandprix]

so does everyone think that i should just do a top swap.

[gtpeddie]

I think you should
