Probably a **** load of money ... You're talking about custom fabbing a precision bracket, that will need to be machined at no small fee, to hold the supercharger in the right place so that it:
Is in line with the belt
allows routing of the intake and charge pipes
Assuming that isnt right the first time, and i wouldnt be surprised if it isnt, they'll have to scrap it and make another one and that surely wont be cheap.
Next, you'll have to have the intercooler and piping custom made, from scratch, with brackets, routing and the works.
You'll also have to hope they get the MAF placement right the first time, otherwise you're going to be playing hop scotch between tuner and fabricator as they continue to point the finger at eachother... trust me, i have been there before, trying to tune around a BS intake some guy made and i honestly was about to tell the guy to get lost because i was tired of trying to make it work.
Most welding services are ~$100 an hour, so imagine a few cuts / welds trying to get things right and you can see how this quickly becomes a lot of money. Its just not worth it, most race shops just dont have the means of making something like this from scratch.
