fuel pump upgrade
hi i've recently purchased a silvia zx turbo on an 84 a plate. the car is running 20 psi. under full load its hesitant. the car has forged internals, cosworth injectors also running a fifth injector. custom fmic, t25 360 degree hybrid turbo. high lift cam shaft and 1.2mm hks steel head gasket. any suggestions to cure this problem? thanks
