Hi I am having problems with keeping clutches in my 240. I have a RB20 swap but it has the original ka trans. Do I really need to get a trans for the RB or is my transmission just messed up because it just turns my clutches in to pizza slices. Lol. If so dose anyone know where I can get one that would fit a rb20 in Georgia.

TMK the KA24, SR20, and RB20 transmissions are mechanically identical, with the exception of the bellhousings. IIRC you have to use the RB20 bellhousing on the KA gearbox to make it work, so I'm guessing that's what you did. If so, you should be fine, and it's something else that's eating your clutch. What brand clutch is it? The few times I've seen clutches fail in that manner (in any car), either it was a cheapo clutch (they bought a non cheap clutch and the prob went away), too weak of a clutch for their power (like 300 ft/lbs tq on a clutch only rated for 200 - an uprated clutch fixed it), or they kept dropping the hammer on the clutch too hard (3 OEM clutches shattered and one flywheel warped and gouged by one guy with a lead foot in a 6 week period).
