i wanted a couple opinions on my bonny,i am trying to swap motors and wanted to know if i can put a 1998 grandprix motor in my 95 bonny without to many costly modifications, let me know they are both 3.8 motors but will it attatch to the tranny?

As long as its not supercharged you should be fine. If one or the other is an L67 then it won't marry up to an L36 Normally aspirated engine.

We need a few more specifics to give you more info? What happened to the Bonne? Lemme guess....upper intake failure?

Can you put your year and trim level (SE/SLE/SSE/SSEi) in your signature?

You can put either engine, L36 (n/a) or L67 (supercharged) in your car. The L36 should be a direct replacement, and will require just plugging all existing sensors into it.

The L67 will require all wiring, and a computer that go with the L67, but both will bolt in fine physically.

If you're going to do the L67/PCM swap, you also need the trans. Not only will the 4T60E you probably have NOT work with the 98 PCM, the differences in the GP PCM'* and ours may be too incompatible with our chassis.

You can grab any L67/trans and then find a Bonnie Wiring setup. Just plug in the bonneville sensors, and get some Bonneville Manifolds.
