the corrolla engines not bad, my old mans got a 90 corolla, toataly standard and its suprisingly quick, nothing to get that exicted about though, anyway being fwd it would be a very big job to fit to a 1200 and not worth it .

pressurised fuel system???

unless i missed something they are just talking about fuel pumps which go after the fuel tank and before carbie, the fuel pump is capable of pumping a certain pressure of fuel into the line heading up to the carbie and they are saying for 10psi boost the pump needs to be able to supplly about 15psi fuel pressure . You also need a pressure regulator (which goes in line after pump and determines fuel pressure there after) to set the pressure at required level, ideally for a turbo though you need a rising rate pressure regulator which works off the boost so that when you have 10psi boost you have 15psi fuel pressure but then when you have like 15psi boost you have more like 20 or more psi fuel pressure for reasons stated earlier

both the pump which can supply high pressure and a rising rate fuel pressure regulator are quite expensive though and a lot of turbo setup have inferior versions of these which become the limitation to the system
