Default 2002 grand prix motor into 95 bonne. HELP!

The motor in my 1995 Bonneville is toast. I bought a 2001/2 grandprix with the 3800 motor to swap into the 1995. I'm not too familiar with the motors computer. Are there going to be any electrical issues? sensors?


Any information would be greatly appreciated.

Do they make adaptors for the engine mounts? or is it going to be a custom job?

My biggest concern is whether or not the computer in the 1995 will work with 2002 motor.

does anyone know if there were a difference in anti lock brakes between the years?

Just swap the engine harness over too. It won't have any computer problems. It'* the same engine.

You'll also have to use the rear manifold from your 95.

Edit-
And the new engine isn't going to effect your brakes.

I'm not all the familiar with these cars here, however i'm pretty sure that you won't be able to use a W body harness on an H body

no, you use the existing bonnie harness. you only swap the block, heads and intakes. everything else is from the original to the car. including the throttle body as previously mentioned.
