engine swap

Asked by Aug 27, 2011 at 10:11 AM about the 2006 Pontiac Grand Prix Base

Question type: Car Customization

I wanna do a engine swap. I found a 3800 SC(motor and tranny,pcm,harness,etc) easily a
complete motor.Came outta a 02 gtp. My question is...will it fit and how much difficulty,is
involved with the swap?

by the time you pay for that other motor and go through all the work and get all the kinks worked out it would be cheaper and faster to just buy a gtp.

thing is...the na/3800 I have in there ran hot and is no longer any good. So I have to replace the engine anyway. Figured I'd jus upgrade instead of going back original. I'm can get the 3800 Sc with tranny and pcm,for 2000. I'm jus wondering,will it drop strait in and bolt up? Whats the diff between gtp and base besides engine and exist?

it will bolt straight up but u have to keep in mind the supercharger if ur grand prix wasnt set up for it u have to try and find the wiring harness with it built in and change the whole harness or go aftermarket sensor to monitor ur boost

what about the tranny? Is the base tranny the same? Thx

02 and a 06,sorry but no it wont work.

sorry again ,no the tranny will not work eather.you got a good idea going but nothing on a 02 will work on a 06.this info is from a guy that owns 3 T-Bird Super Coupes with the 3.8 supercharged engines.so trust me when I say it wont work.sorry.just enjoy your ride.

well,what if I went with an 06 sc3800? Computer and harness would be,all I needed? Just weighing my options. I have gt body and interior that's in A1 condition.But need a engine. Really want the sc3800

sorry not gT but Go

sorry not gT but Gp
