Completely different engine. The 3.3 is a Great engine. IMO, one of the best V-6's that GM ever made. It would probably be easiest to cut out the entire subframe with engine, trans, and running gear from the old car and weld it into the new car. Also, it will require all the old wiring, ecu, etc. from the old car. You will have to fabricate new exhaust, cooling, A/C, fuel hose, steering, etc. The swap is possible if you have enough time and money but it will not be easy.
