Variable Intake Runner Length
There are two sets of intake runners. They are selected by a vacuum switch connected to a valve in the intake plenum.

In this picture you can see the intake runners. The bottom runners are for the rear bank of cylinders and the top runners are for the front bank.

Crank Angle Sensor
The VE30DE has no distributor, you can advance the timing by loosening the crank angle sensor and rotating it slightly.
