Thread: Engine Swap?? 2006 to 2004

Hi all my wife wrecked her 2004 grand prix and I found a 2006 grand prix gtp and was wondering if all the parts were interchangeable and if its possible to swap the other gtp motor into her 2004 car? I heard about maybe reprogramming the pcm? thanks.

no you have to take the wiring harness and the pcm from the 06 and put it in the 04 i believe

Hers was a gt. but other than motor doesnt all the body parts interchange? thanks for the replys! would i have to reprogram the pcm or just use all the brains and wires from the 06?

in 2006 the GTP was just a GT but still S/C!! and if she wrecked the 04 why bother rippin apart the 06??

ya I was thinking about that, the only thing is Im not sure how bad the 06 is compared to the 04 and if the 06 has a title or if its salvaged.

well the 06 for one is S/C and has a little better trim in the interior and is actually black and not charcaol like the 04 (if they are both leather) and if it has a good title and the car is clean then take it to a mechanic and have them look it over and then just drive it. and does the 06 have a less miles then your wifes 04?

Well He said it only has 75k miles and my wifes has over 100k. the only prob is he used the tranny out of it, would my wifes gt tranny hold up to the other gtp. Im waiting for the pics of it but it sounds like it has nicer interior and features for sure. so I may just fix up the 06. its a coffe color he said.

no your wifes tranny wont hold up you well need the tranyy that goes with the supercharged motor.

Well would it hook up to it and work at least? I could take it easy as money is very tight and cant really afford different tranny.

im not sure

lol ya itd be hard not to get in it with more power like that. but she would mainly be driving and she isnt a hot rod thankfully.
