Tasty, they have a really strong bottom end that will take more than double the HP before you have to build it up. They make TONS of parts for them as a result. The basic engine design of that particular inline 6 has been around since about the early 80's. You can put nice rubber out back(something in the 300mm range) that will at least give a valiant effort to hold the additional HP. The other turbo Japanese cars of the time were the 300ZX TT, RX7 TT and the 3000GT VR-4. None are as build friendly as the Supra.
