big differences, even more then brett listed, go on supra forums if you want a good break down on whats different between a 2jzgte and 2jzge. and so you know for toyota engine codes the t stands for turbo before the last letter. so 2jzge = n/a 2jzgte = twin-turbo. like i said, unless you have an sc300 donor car that isn’t worth making a running car out of i would get a 2jzgte swap.
