Would a 2.4 ecotec fit and work into a 03 cavy???
you need to search. you would have to swap out ALL the electronics from the cobalt to make it work. yes it could but it would be a hard un tried swap.
the motor is out of a G6. All wiring isnt there and its from a wreck car. Very good shape and only 10K miles on the motor, I blew my motor so I'm looking right now
with the work...im sure you could do it..
if a northstar v8 will fit
...then then 2.4 eco should..but its most likely gonna be a pita!
