Monsta torque is in Perth, ZF Australia have all there boxes built there. Work I have had done is stronger input shaft, modified pistons, extra clutch packs, steel pan and valve bodies. It should be pretty good for the power I'm chasing and built more for my requirements. I am yet to drive the car as my drive shaft Is not back. One thing he doesn't touch is the torque converter, I personally don't know why people would want a big stally on the street anyway
