Supplied by AF Rayspeed, these fit the larger 200 casings.
 
The kit consists of:
RB22 cylinder, Piton complete, Dual reed valve assembly, Inlet manifold, Inlet base, Head and exhaust gaskets, 6 inlet manifold bolts and 2 exhaust studs.
 
As this is one of the most powerfu kits on the market, you will need to fully upgrade your engine to cope with the power.  We would recommend: A cassette clutch, touring/racing expansion exhaut, 30mm flatside carburettor, a one piece top chain guide 9we do not use a bottom one), a stonger selector spring and a race crank.  These are all available from us.
 
Please see the recommendations on engine spec and fitting instructions prior to buying, to check your engine will cope with the extra power, and what else you may need to buy to complete your engine - http://afrayspeed.co.uk/pages/rb22-fitting-instructions 
 
Please not this does NOT come with a cylinder head but is available on this website - standard 9.5:1 type
