you could buy a corrado g60 with the money needed for all those parts!
But then I'd end up with a corrado and not a golf!

+ it's not THAT expensive. £300 for charger, £250 for MS, and add about £500 on random bits and bobs is just over a grand...for a grand you get a crap example of a genuine G60.
As long as I can fabricate my own brackets and other bits it shouldn't cost much above a grand.
Isnt the m45 the same one they use on the bmw cooper s? These were going for as little as £45 new a couple of years ago when people were having the 'works' kit fitted.
adaptorman said he built a supercharged 8valve using a merc charger, might be worth asking him if you are struggling, I'm sure he posted some info on his build thread the other day about some MS wizard that he had met
Yeah the M45 is from the cooper S, on ebay they are anything between £250 and £300 as far as I see, only 2 on tehre at the moment however. I'll chat to adaptorman at some point, after all he can probably build a supercharger using nothing more than a can of beans and a pencil sharpener
