You'll need a GSXR K7 stator and rotor (750 or 1000 I think) and either a modified alternator cover or a specially made one from Rick O

That's not too bad to get hold of. I've already got a spare motor on pieces so can modify the cover or have it modified if it's a major thing. It's basically save up and buy parts until you have everything then put it all together then?

To modify a cover you'll need a bracket. The bracket is bolted inside the cover and holds the stator in place.

does it give better acceleration like a car does?
