Yes it is possible. I'll be doing it in a few months but in a VH.
There is a kit available for this conversion so it bolts straight in. i'm pretty sure the master cylinder stays the same but the booster is modified. Give Sydney Race Brakes a call to find out what they modify to make it fit - Performance Brake Packages
