Just wondering if I currently have the SR Motorsports pullies on the car and get the Greddy Turbo kit, do I need to take off the SR pullies ? I would understand if it was an SC unit, but since the Turbo is driven off the exhaust gasses would the pullies have any interaction with the turbo system ? Also the Greddy will come with the Airinx air intake system, but I currently have a Rotary Extreme unit. If the RE unit (looks like it will flow better) is better do I have to replace the unit or just use the RE unit with the turbo kit ? Any help would be appreciated.

The turbo has no clue what size pullies you have.
