Engine Swap for 94 Sunbird

Monday, December 02, 2019 8:49 PM

I have a 94 Sunbird with a 2.2L and would like to swap it with a more current 2.2 Ecotec or a 3.4L engine. A friend told me that I would have to change the subframe/engine cradle on the Sunbird in order to install either engine. Is this correct?

I know you will not have to change the suspension supports to install a 3400.

Here is a thread with some information on putting in a 2.2L Ecotec.

Lots of things have to be changed to get it to work.
Seems the 3400 is by far the better option. But, you'll have find a V6 car for a few things, of course.
