i have a 94 olds achieva with a 3.1 which is totaled and a 96 grand am can i put the olds enbine in the grand am?just wondering if anyone has ever done it i have both cars so i have the wiring can it be done?

Welcome. Yes, it can be done as both cars are essentially the same once you remove the exterior sheet metal. You would have to swap the engine cradle, motor mounts, engine harness, dash harness, ecm, air bag modules and sensors, transmission I believe, and possibly the body harness, the gauge cluster, not sure what else. It's alot of work, but it is doable, especially since you have a complete donor car. Good luck.

no its not that hard !
if thier both 3.1's the swap isnt that bad.

Mostly sensors that might not plug on to the old,
then you need to fit one from the GA so the harness will connect.

I had a 93' GA with a 3.3, and swapped it out for a Cutlass Ciera 3.3 and I changed very little. Just kept the GA coils, cps, and a couple other things. Bolted right up.

But I'm not 100% the 3.1s from pontiac to olds are a match, but I'll try and find out.
