I plan to do it in the future. But afaik larger crank pulley will need a modification to front engine cover as well as rerouting oil galleries. Also other pulleys must be changed (alternator, waterpump) to keep their ratios. And also some idlers. I have some excel calculator from cosworth and the calculations looks promissing. Second option might be 2nd belt for driving the SC.
