I heard that with an adapter kit you can use a supra transmission on a rb25 engine.

I don't know makes the adapter kit, but they said it's doable. That would be awsome.

Getrag 6spd rb25 240sx, sweet. Has anyone heard of this?

 

I was thinking about doing this a while back.
You would need an RB26 with an R34 bell housing and a Supra's getrag. The trans will bolt to bellhousing, but the hard part is getting everything in the car working.

Someone said he's had the Supra 5sp on an RB25 in Australia.
