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.
