VDI Help

NoDOHC · 09-21-2010, 07:12 PM

The VDI (the actuator on the intake manifold) requires the car to be driving to operate. IT is controlled by the ecu using a solenoid valve. If this valve fails or the air pump that supplies the pressure to operate the VDI fails, you have no VDI. A lot of emissions removal schemes end up going awry and costing 25ish Hp by making the ports and VDI disfunctional.

There are several fitment threads in the wheel and tire section, but the short story is that you will have to roll the fenders to run 17X9s, the 17X8s fit ok.
