I have a the car listed above but the transmission is no good. I have a friend who has a the car only a four cylinder, but is having engine issues. so I'm wondering if we could take the six cylinder and swap it out the four cylinder?

Good morning,

The engine will fit but you need the complete wiring harness to be swapped as well along with all components and exhaust.

The transmission is different as well. The 4 cylinder transmission is different than the 6 cylinder transmission.
