the main problem with the ib5/bc aint the gears its the main shaft.
for your Łk you could do a focus rs conversion.
Sunny's wasn't straight cut though was it, Gary? Thought his was a CTS Stage 2+? And yes, I think he break that a few times, as did Paul Jonhson.
I've heard of the BC straight cut boxes running 300BHP and Torque without any problems. The problem with the BC is the design of the gearbox casing itself, being inherently weak and twisting, destroying the bearings.
