looks like youve got a big job ahead of you mate
dont think the 200 came with air con did they ? if they did you could get shot of it and fit a supercharger in its place. if not your going to have to mak a bracket for it and get a custom drive belt made for it.
you seem content on induction, what about the exhaust ? no point in getting all the air in the strangleing the engine as it cant get out.
and the same as TN whats the electric boost valve ? not one of those bloody electric superchargers thats run off the battery ?
