2004 Monte Carlo SS engine fit into 1998 Pontiac GTP?

Question

Will a 2004 Monte Carlo SS 3.8 supercharge engine drop into a 98 Pontiac GTP? Are the electronic (wiring harness) connections the same?

Answer 1

yeah you can but the electronics will be different.  

Answer 2

They are the same engine the L67. The wiring harness will be different off of the new engine, but if you are having a shop do this, they should be able to handle it if you cant.

Answer 3

It should fit but I think its not a good choice. You can get a newer Grand Prix with the same 3.8 supercharged engine without having to do a motor swap. Or better yet trade the Grand Prix for the new 08 G8 GT. Those are a h**l of a lot better. Powerful V8 engine, Rear wheel Drive, 6 speed. Man you can't go wrong.
