ah well. must just be to screw us for services then.
Well, if you really want a Vectra supercharger, you'll need the following.
A new cambelt, as it has 1 or two more teeth than the original one.
The supercharger itself (obviously) as well as the bracket the charger sits on, which replaces the bracket that holds the cambelt pulleys.
New idler pulleys, with an enlarged centre complete with different bolts.
New aux belt, to incorporate the additional run of the belt.
Then you've got the hassle of getting the airflow from the charger to the throttle body.
There's a pic of my engine bay on mig somewhere, I'll try and find the link
"slap on a turbo"....on a budget
Not the prettiest, but the sound of the supercharger is to die for.
