did you stand next to 2jzgte lying outside. its a whale when attached to transmission. yr savanna will be way off 50:50 front rear balance. rotary from rx8 is what you need, you take care of engines. proper installed rotary and shutoff timer etc, good fuel you should be able to manage rotary engine . . to fit 2jzgte in narrow car, you may need to widen yr car wheel base .. it may get too technical to redesign structure for engine. also driveshaft will be shorter. means more torque less horsepower. the diff housing needs to be bigger and bigger diff has to be fit in...plus all the chassis support bars. I assure you nobody who knows cars would recommend swap unless done by pro to rebuild strengthen old chassis. do us a favor, stay with rotary engine, if you blow that ,, replace.. no 6 in-line long block recommended without professional designers.
