cheers, I didn't think of getting a Gen 3 box. I expect NA ones will be a little harder to find. eBay is swamped with turbo ones, but that's not much use to me...
I was think of just a stock Exedy, but the engine has a decent amount of torque, so maybe a heavy duty one would be the best bet.
Quaife was my other option, which would be kinda cool, but cash is the key here
we'll see how it goes
Thanks for the advice :)
