Engine swap ?

Will a 94 3.8 Bonneville engine fit into a 93 Grand Prix SE with the 3.1 engine in it?

Is it also the same trans?

What Kind of Headaches could I expect?

Thanks

Tom

Not too sure here... But you would need the PCM and the harness, and some brakets and engine mounts... If you really want to do this, I'd take a good look at a buick regal with the 3800 TPI engine.. I think the Regal( about the same year as the 93-94) is also a W body.. Also remember the 94 bonnie has a hybrid year PCM... Part OBD I part OBD II. This should give you an idea of everyhting you will need to have or do... Maybe someone else can jump in here and answer...

Umm... I might be crazy here but I thought 95 was the hybrid year...

The Boat is right. The 94 was purely OBD1, with the 16-pin ALDL.

Um, pardon my ignorance, but why can't I hook up my 'Wal-Mart special' code reader into the connector under the dash. The connector in this car (1994 SLE) is totally different from my 1992 and the 1993 SSE parts cars.
I thought this was OBDII!?!!?? I was going to go buy the $53 GM scantool @ NAPA, but now I wondering if it will work.
