you should install a turbo boost valve (instead of traditional bleed valves) to get more turbo boost. there are a lot of items at ebay, so don forget respect the stock limits.

i have do this in my thema turbo 16 because there is no electronic choice with this preistoric electronic control units. so don forget be very careful and do readings of air fuel ratio, you will run lean very fast at hight rpm and you should install a fuel regulator rising presure

get a 16v not worth spending money on 8v,only small bhp gains with bigger turbo,BUT,big torque losses. dont waste your money trying
