Well you dont really need to spend 7500 on a good turbo setup, all you need is some good mechanical knowlegde, and an exhaust shop, and parts shop, the tsa kits a good but I believe you can make a kit urself abit cheaper and they are very easy to fit, source a turbo, get someone to make a exhaust manifold, some hoses for the turbo, exhaust system, intercooler, unichip and intercooler piping. all this u could find for under 5000 grand. run 10psi and you will have over 200rwkw on a EB-AU XR6.
