Our own workshop and in house dyno facility we are able to design, develop, test and manufacture the best parts for your vehicle. This is Protuners ultimate E36 intank fuel pump upgrade. We have made over 700bhp with this kit. This replaces the weak links in the factory fuel supply system , by replacing the pump , hose , pump wiring connector and fuel pump relay with uprated items. The pump kit comes complete with the pot and replaces your standard pump in the fuel tank. This is a plug and play upgrade (it will require a small amount of wiring to attached the uprated wire harness and relay). The pot is fitted with a new genuine Walbro 450 (274) pump which provides approximately 150% more flow than the standard system. This fuel pump upgrade is e85 compatible and will support well over 650 BHP. This kit works great for 2JZ, 1JZ, M50 and M52 turbo conversions. The kit will not affect the standard fuel tank syphon system or level gauge. This can be posted or you can collect from our workshops in Coventry.
