Ah ha not surprised to see a BB using Wossner Wossner do Cossie and RS Turbo ones too, were some on ebay..

Sure Andy at BB would be happy to give advise if it is one of their kits

Clio tuning / turbo conversions seem to be increasingly popular these days, BB's low boost Clio conversion was bit of a beast (7psi IIRC) K-tec Racing have done some blinding conversions too (not sure what there 172 is putting out at the mo, at Snetterton tuner GP last year I think Dave was marketing it as the 272 conversion, that is very impressive car)
