The T5's go for a good few quid now don't they - a bit of thinking outside of the box (no pun intended), and if you have certain bits lying around it's a cheaper way to get a Rwd box?

If your not running masses of power it should be fine?

I think your main problem will be sump related.

Could end up being a lot of messing but if you are handy with tools/alloy welding and such it won't be too much of a bother.

The RX8's gearing/ratio's lead to a bit more of a ball ache with diff's and stuff don't they or am I thinking of something else?
