I searched this thread, and couldn't find info about it. Does TOM'S make a supercharger compatible with the 1UZ? If not how much work would it be to make the one for the 3UZ compatable with the 1UZ?
I can't answer your first quesyion but the second one is heaps.
The port shape and angle is different.
That said a little ingenuity would make adaptors using a 1UZ manifold to get the ends off the runners and the 3UZ runners and it should work well. A bit of TIG work and Bobs your Uncle.
