Yes - I emailled Jim Goodroe - he responded and told me that Eaton had stopped making the blower units he used so they had run out of stock. I responded asking if there was any possibility of a kit using another blower, but.... no response to that question
I have also emailled AA and asked them if they do kits for the 318iS - will see what they say.
I was really keen on just having a Supercharged 318 - being really fast doesn't help when the speed limits restrict you quite severely over here, so I was on a quest for more horsepower and torque and thus quicker acceleration..... hence me wanting a Supercharger and not a Turbo unit. HOWEVER, I am an inveterate tinkerer and the thought of dropping a 2.8L is interesting... what else needs to be modded to enable that?
That aside, I will continue my search for a Supercharger kit..... the thought of actually bolting the thing on is really very appealing......
