They don't have the same block and internals. Only the crankshaft is the same. The TT block has oil squirters, and lower compression pistons (specially designed to utilize the oil from the oil squirters). They also have very different braking systems (abs ecu, calipers, etc.), suspension, transmission, differential, etc., etc.. They're two completely different cars! If you want a TT, don't buy an n/a.

The only thing is that I have already purchased the car and I am just going to have to swap in a new engine, tranny, brakes, etc.

please run the numbers. You'll find it'd be less expensive to sell your n/a and buy a tt than doing all those swaps

Well I have decided to sell my N/A supra and am now about to trade it in and buy a TT supra.
