Do you think a V6 from a chevy cobalt or impala fit in my chevy corsica?

you will need the v-6 front suspension/engine cradle. v-6 computer& components. transmission from the v-6 also... the tranny needs to handle the v-6 torque. 2.8L v-6 was the engine for this car. quite a big job but do-able.

you will need to replace the computer and all engine wire harnesses.

the cobalt doesn't have a v6, it has an inline 4

cobalt 4 cyl, would be an easier fit. scrap yard!

wait... a corsica can have 2.0, 2.2, 2.8, 3.1 liter sizes.

you would be better off looking for a 3.1 or 3.4 from similar years with the ecu and harness. swap would be much more simple. but in all reality it will probably be easier and cheaper to just sell it and buy a different car.

Try finding a totaled corsica or similar model, just make sure the damage isnt on the front end.
