is there an alternative to a performance clutch for a budget

hello,
        anyone got any advice for me on clutches, ive got a dx engine and 5speed box but i have also got alot of toque from the turbo thats stuck to it . i have a black diamond clutch at the mo but that is slipping at 185lbs on 9psi and i still have about another 40-50lbs to play with at 1 bar boost .So you can see my problem, is there any alternative solutions other than buying a £400 performance clutch?
