iv been thinking about this too. I would go slightley diffrent approch and go: 6boost high mount manifold with extenal waste gate gt35 turbo, turbo smart gate 38mm very large front mount cooler, and pipe work front facing plenum flash tuner drill and tap sump run stock compression with low boost 8psi max, still good off boost toque and high rpm boost. I would run the whole package in a ba xl ute stock as a rock, white. stock rims with good tyres. buget $15,0000 including the purchase price of the car. that's how you build a turbo 6 that wont attraced police attention. ps: leave the bov for the siliva boys. lets face it if you buy a xr6t you going to want to mod it with lagers turbos and gates later on so start simple and and purchase once.
