One of the most important upgrades for the Porsche Turbo engines is to replace the factory Bosch diverter valves. The factory valves are prone to leaking pressure under increased boost when the car has an upgraded ECU flash. As well, the factory Bosch valves will taper boost off with the diaphragm design even at stock boost levels. To help keep the boost pressure constant all the way to redline, upgrading the stock diverter valves to the DesignTek Racing Diverter Valve Kit will improve your cars overall performance.

These valves are CNC machined 6061 aluminum which have been precision engineered to fit with the stock or aftermarket F-Hose and intake return hoses. The internal construction of the valve uses a machined piston with proper o-rings to ensure a smooth motion that is air tight to prevent any boost leaks. The spring has been engineered to hold moderate to aggressive boost increases on the 996TT and Cayenne vehicles. The valves feature a 90 degree removable swivel connection for easy fitting with the factory vacuum hose. If needed, the top of the valve unscrews allowing you to re-greased and service the valve. As tested, these valves are a great upgrade for stock K16 or K24 cars and have even been used in our 700HP turbo kits.

9m uprated billet aluminium 718 boost recirculation valve

Direct replacement for the  factory plastic replacement recirculation valve which are prone to leaking boost pressure and can cause boost back feeding through the inlet plenum which can cause failures.

Unlike a Blow-off Valve (BOV) which vents back-flowing charged air to the atmosphere, a recirculation Valve protects the turbo compressor from being stalled by redirecting the back-flowing charged air to the turbo inlet pipe.

This high-pressure fuel pump delivers fuel from the low-pressure system to the injectors at the required pressure for direct injection, ensuring efficient combustion and engine performance.

Function
• Generates high fuel pressure for direct injection systems
•  Ensures precise fuel delivery to injectors
•  Supports optimal combustion and engine efficiency
•  Maintains consistent performance under high load
•  Designed to operate in high-temperature, high-pressure environments

A failing high-pressure fuel pump can lead to poor fuel delivery, reduced engine performance, and starting issues. In high-performance engines like the GT3 and GT3 RS, precise fuel pressure is critical - any inconsistency can significantly impact power output and drivability.

Replacing the pump ensures proper fuel system operation, restores engine efficiency, and protects against potential engine damage caused by incorrect fuel pressure.

When to replace
•   Engine cranks but fails to start
•   Noticeable loss of power or performance
•   Engine misfires or irregular fuel delivery
•   Fault codes related to fuel pressure
•   During fuel system or engine rebuild
