Require either one of the toyota SC12 or SC14 superchargers
It dosn't need to be in good condition as it is going to be cut down in size to suit a bike
I hope sombody out there has one that will fit this catagory as cutting down a good one would be a shame
there is a subaru s/c (off a kei class car) - same design as the toyota one, but smaller - speak to andrew p about them, as he often has them (Andrew P at toyopro)
