I have a 3SGTE RWD swap on a 75 Celica. Takes a lot of time and bling(if your a broke as$paragus like me)
Here is the basics of what I have for it to be RWD. There is a lot more other stuff but I think these are the Main parts for the RWD. I got most of my RWD conversion info from Toymods.
-3rd Gen 3SGTE
-2S bellhousing on a W58 Transmission. But you need to mill 5mm from the Bell housing for the input shaft to be far enough in (also look up a 4Y Bellhousing)
-2s pan and oil pump
-Custom motor mounts (I have a set of 2s which works too, but I made my motor mounts so I could use the Megan AE86 Mounts)
-Custom Front Facing Intake Manifold (I've seen some people do their RWD conversion without a FFIM)
-Custom Turbo Manifold with a Turbonetics T04E
