If I remember correctly, the 3.1 has an oval throttle body, while the 3.8 is round, but anything is possible, you would have to make an adapter plate most likely

My wifes GA has a 3.1L motor and I do believe it has an oval TB. But I dont think it is oval on the side that connects to the intake manifold. I can check if I dont forget if you need me to.
