Absolutely zero experience in forced induction but I have some knowledge.
You will obviously need the kit to start with. Then work out what brackets, pulleys & belts you need & set them up.(Blower will most likely mount on manifold but will need to be supported whilst manifold is constructed). From there you will need either go to the exhaust shop (or be able to DIY) to get custom intake manifold built in steam pipe.
May as well go to an F8b as you will most likely need to re-build your engine to cope with the boost from a supercharger (have you seen the conrods in an F5a?) Have a look at the turbo conversion threads to get an idea of what is required.
So many delays to getting my MB back in order with 993cc & 5 speed transaxle... neighbor issue gone, donor shell up on rotisserie, new sheds on the way.... another project also..
