Where do you get parts?
Rockauto, Toyota, here and there. The bottom end is the same as a 2t-c, which is just an old corolla engine, the top end is harder to find parts for. What do you need parts for, anyways? It's a rebuilt Toyota engine, it should be good for another 500k miles!
And is there a bellhousing? Lol
Yep, the Ts and Gs share a pattern, so you need one from a 1G-powered Supra/Celica XX/Chaser/Soarer to reuse your W58. Otherwise you need to find a T50 with a 2T bellhousing from a Corolla.
