    hi i was just wondering if any one can help me out with the wiring i have checked the thread already devoted to this but it does not mention wether you can use the electric dizzy from a vk calais on an est motor, has any one done this? is the electric dizzy from a vk calais differnt to that from a blue motor?

    same dizzy and will work just fine, before you connect the vacume advance suck on the pipe on the dizzy and make sure you cant suck air though it. If you can either just use it without the vac advance connected or replace the vacume advance.

    Vacuum advance is a system that when the engine vacuum is high, it advances the timing. Basically, when accelerating under load, the engine needs a little more time to burn the fuel. So the spark must occur a little earlier. So it will help fuel economy,power & make the car more drivable.

    cheers
