Question for anybody who might know. Will a cavalier l61 engine fit in a cobalt? I want to build a engine for turbo and I need a engine. I see lots of cavalier engines for cheap with low milage, which I think would be good start. I just need to know if I buy one will it drop right in? or will I have to do some serious modifications to make it work? I just dont want to make sure I have my stock engine if anything goes wrong.

 

L61 is a L61...the engine itselt is pretty much the same in both cars...although i believe they do have diffrent hp ratings

 

Physically maybe, but it would be nearly imposible to get running w/out a stand alone computer($1000+) and it would be a tuning nightmare... you would be better off buying a turbo kit(yes they are available now)
