Hey I found a 3800 supercharged engine with low miles. It have the full harness and computer for 200. Would it be a good idea to install it in my 97 grand prize GT?

I just paid $300 (plus an additional $110 for shipping) for an S/C engine with 100k miles on it to put into my 99 GT. the yard apes at the junk yard cut the harness, but it had the ends I needed to make it work.
 
Wat All did you have to do to put it in because it have the harness and computer with it and i already have my old engine out of my car

Do some more research before you jump on it. 97 GPs use the 4t60e trans which uses vacuum, 98+ don't, not a big issue. The Pcm on 97s are also a little different, same connectors but I believe you need to use a 97 pcm, one from a gtp would work but you'll need to program it for the gt trans. There's probably a few things I'm missing.

It can be done it's just not as simple as dropping it in and plugging in the Pcm. If you get a 97 gtp motor, trans, Pcm, and harness then it would be that simple.

depends on what tranny you have if you should sc or not. maybe find the tranny too if need be.

the pcm wont work for your tranny, it needs to be tuned for that. run a tune for the wrong gears and the tranny eats itself.
