Aside from getting a TT, the best way would be to get a wider exhaust and do weight reduction and suspension. There's not much power to be had in a N/A engine. I just got a 7M-GE this month and I've already started saving for a 2JZ-GTE. They get about 70 more ft-lbf than the 2jz-ge. You could always just upgrade your engine to a TT. I'm not too sure on the mechanics of the 2jz-ge, but if you did that, you could get more power with it that way due to higher compression pistons. Of course, you'd have to upgrade your ECU, wiring harness and your entire fuel system with it. Granted, doing all of that would probably still be cheaper than selling the car you have and buying a TT MKIV. Those things are preposterously expensive.
