My son has a 96 non turbo Eclipse and needs an engine. I got a 95 turbo Eclpise for free it just needs a Transmission. Can I put this engine in my 96 and use my transmission?
you could with some fabrication. the engine mounts are different. find a trans for the turbo car and drive that.
So to actually answer your question, NO, you cannot put the turbo motor in your non turbo car with any level of ease (since you have both cars, go out and look at the fact that the engine on the turbo car is on the drivers side and the non turbo engine is on the passenger side... they aren't even close to bolting together). You should definitely replace the tranny on the GST and drive it.
