I have a Mal Wood Option 3 in my car (changed from T5 to T56), organic single plate clutch with new flywheel and their alloy CSC. I had a T5 in my car, but funds at the time allowed me to change it out for a T56, I did so for reliability's sake, as I knew with the power I had planned it just wouldn't last... I have a mate in QLD who has a T5 equipped XR6T ute and he is now in the middle of doing the T56 swap, he is running just over 300rwkw, and his first 3 gears in the T5 now sing like a bird. Be very careful mate with the power (torque) you are planning... the conversion to a T56 isn't a cheap one. Jack
