just replaced my XR6 with an XR6t, atm it is a completely stock '04 BA 4sp Auto.

Now I've heard of the T5 having issues with not being much good for over 250kw.... i don't know what the car has at rw tbh but i believe stock is 240 at fly. i want 300+rwkw, I'm fine with doing most things under the hood (engine transplant in just over 4hrs solo in '97 EL using a gregory's ) but i have no idea where to start on performance.... naturally exhaust and intake 1st, but what size and which one is best?? post that what does one need to do to get more boot and how much can that 4spd take before i break it???

cheers all
