so as far as I have read for an E153 swap (3SGTE) you need:

ST205 rear mount bracket
normal rear mount
ST205 Cables (possibly ST gables)
inners of an MR2 axles
outers of the GT axles
3SGTE full clutch kit is good.
is that EVERYTHING?

what do I need to look out for when you do the swap?

Ive done as much reading as I could find, and I am piecing it together from thread to thread.

Thanks a Ton.
