Everything is identical, the only slight differences is the 4K engine might have emissions crap on the carby. A lot of guys ill use the 3K carby as it doesnt have it.
If its anything like when my Swift was hit the wreckers will give the insurance company a $0 offer so you'll get a 'market value' payout and get to keep the car.
They are billet aluminium so yeah.

The AE92 came as an AWD sedan and wagon, but I doubt Aussie got any. So yes, its possible. I think the chassis are different so would probably be easier to import one. Theres the SR-5 4WD wagon too.
