Interesting question and actually i dont have a clue...
One way to find out is to calulate how much fuel your jets can flow, along with the fuel requirement under boost and then find out the needed fuel pressure... If i remeber correctly weber 40 work at 2.5-3.0 bar in NA mode, so i wouldnt be impressed if your engine will require something like 6-7 bar (do not take it for granted plz and make your calcs or ask someone that has done it before or sells kits).
