step 1- remove the blow off valve. place it on ebay/craigslist/in a drawer. it will not be needed.
step 2- acquire a diverter valve. one of the large ends goes into a small tube coming off the intake hose connecting the turbo to the crosspipe at the bottom of the radiator (passengers side of car). the other large end of the DV gets connected to the turbo inlet pipe thru another tube. then the vacuum line goes from the small port on the top of the DV to one of the vacuum connections on the intake manifold.
