Not personally, but I've seen a couple with 1UZ swaps, they looked good. On this forums probably the closest to your application is Al "ToySnake" who swapped a Ford Cobra V8 into his 2nd Gen. He's done a ton of work to his car, probably a good resource since the 2nd Gen Celicas also have a steering box like the first gens. I believe he converted his car to rack and pinion as well.
