Wire ties

Misc. tools

1. Remove your intake system from the car so that you can clearly access the wastegate
   
2. Remove the 4 inch tube that goes from the turbo to the wastegate, this line contains an orifice that is sometimes used to regulate boost.
   
3. Remove the front passenger side wheel
   
4. Remove the inner wheel well lining
   
5. Look inside the wheel well, behind the door, and pop out the rubber gasket that leads inside the car.
   
6. Fold the 25 feet of vacuum line in half and fish the ends through the hole on the passenger side hole near the anti-lock brake mechanism (see picture)
   
7. Go inside the wheel well and fish the lines through the gasket you pulled out earlier
   
8. Find the lines inside the car and route them to the desired mounting location of the valve. I choose the ashtray because it makes the valve easily accessible and safe from being bumped accidentally
   
9. Remove the ashtray and disassemble the bottom portion. There are four screws on the underside. This leaves you with just the top of the ashtray
10. Remove the center console piece that surrounds the shifter
    
11. Drill two holes large enough to feed the vacuum line through in the front and rear portion of the console, where the ashtray fits in (see picture)
    
12. Insert the routed vacuum line into both holes, and attach the valve with wire ties. Drill 4 small holes around where the valve will sit. Tie down the valve with wire ties to the bottom ashtray portion of the center console (see picture)
    
13. Open the valve all the way
    
14. Replace the center console and place the ashtray cover over the valve
    
15. Inside the engine bay, route the hoses to the area where you removed the 4 inch hose earlier.
    
16. Cut the hose so you have enough length to reach the nipples of the turbo and wastegate
    
17. Attach one hose to the turbo, and the other to the wastegate. It doesn't matter which one goes where (see picture). Secure these hoses with clamps or wire ties.
    
18. Replace the intake system, wheel well liner, and wheel.
    
19. Make sure the valve is all the way open, and take the car for a test drive. Floor the car in 3rd gear, you should be seeing about 10 pounds of boost or less on both turbos. This will depend on the size of the vacuum line and valve that your are using. If you see more boost that you want as your "base boost" then you need to get larger vacuum line and a larger valve to allow more air flow.
    
20. Make a couple full throttle runs in 4th gear and start closing the valve slowly after the turbo switchover. Keep closing the valve until you have the amount of boost that is desired. It is important to make the run in 4th gear. You may have slightly lower boost in the lower gears. If you plan on running your car in 5th gear full throttle, on the 2nd turbo, be careful. The boost under that high load may increase slightly above what you initially set the boost at in 4th gear. Since 4th gear redlines at 140mph, I never run the car at full boost in 5th gear.
