Hi all..I'm new to this forum but found this thread interesting.
Ive just watched the movie on thursday and yes it is possible to
transplant a bigger and more powerful engine into it.
I believe the engine that was transplanted after the untuned 4AGE
died was one from a MR2 Class C engine. MR2's are either fitted
with this or a 4AGZE (Supercharged). It bolts straight one to
it..cause both are rwd engines.
The other engine I would speculate is a 2.0L engine from a recent
model levin with is an FF......not sure if that fits straight in
but it might work. The modifications that have been done on AE86
are transplants of SR20DET (see one drifting at QLD raceway), 12B
rotary(Look up Hot4S magazine), 4AGZE, 4AGE with individual
throttle body....so I don't see why can't a Class C MR2 or 2.0
Levin be in there.
