The 2004 and the 2005 are both seventh generation (2004–2008). The engine should drop in. Check with other owners on the forums to see if there are any details that might be a problem. -- http://www.grandprixforums.net/ --- http://www.clubgp.com/newforum/default.asp? cookieCheck=840780044 --

You may need to have your computer reprogrammed (flashed) using the doner car's vehicle identification number. HTH. -Jim

it depends on if its gt, gtp, gxp, all have different sized motors and gtp and gxp have superchargers. same size motor AKA 3.8L will swap out. u will have to reprogram the censors as well. but you can do that pretty easy

If its an SE, GT1, or GT2 the engine will be a standard 3.8 and should drop in no issues. Theres a small chance youd have to program the pcm but just use the one from the donor car. The GTP is obviously the supercharged one, it will take a few here and there parts but nothing all too extensive. Then you have the GXP which is NOT supercharged. its a 5.3L V-8 that i wouldnt waste any time on.
