Grand Prix Engine swap

Asked by Feb 23, 2016 at 05:59 PM about the 2005 Pontiac Grand Prix Base

Question type: Maintenance & Repair

My engine and transmission are bad in my 05
Grand Prix. I found a totaled out 07 Grand Prix GT
and didn't know if both were compatible. I've heard
that from 04-09 they should be but didn't know if
the turbo made it incompatible. Can anyone help
me out?

Well it is true that from 04 to 08 engines can be changed as long as you swap the same engine, for example 3800 naturally aspirated can only go to another 3800 naturally aspirated. but N/A 3800 can't go to a supercharged 3800 or vice versa. you can do this but it will take a lot of money and will include a wiring harness and computer transfer also. I don't think the engine you want is turbo charged it should be supercharged. If it is turbo charged then you are going to have some difficulty getting things to run correctly in your car. The totaled car would have to have been heavily modified and done all kinds of things to be converted to supercharged to turbo. If it is turbo hopefully you know how to do a lot of work on cars. Hope you get your car fixed. 3800 are really good engines.

An '05 GP base is not worth very much even if it runs. With a bad engine and transmission its worthless. Unless you are just looking for a project because you like working on cars its time for this one to go to the wreckers and buy one that runs. There are lots of nice ones around for not a lot of money. If you want the performance of a GTP then buy a GTP, don't try to make one.
