I've done some pretty thorough research.

Don't be tempted by the cheaper systems as they have components of inferior quality and are less suited to our type of engines.

BRC is the best system for high pressure turbo's as it will easily cope with the extra oomph. I've been quoted £2100 inc vat as a guide. Prins, although well regarded, will struggle to cope with the power. Do factor in servicing costs, though, as this will mean payback may be longer than you think.
