What is the boost control kit for ZD30?
Full boost control kit to suit Nissan Patrol ZD30 Di & CRD. Choice of EGR blocking plate (CRD left, Di right). High accuracy needle valve. Quality silicone hose that will not split or burst under strenuous conditions. Full pictorial instructions provided on USB key.
What are the issues with the ZD30 engine?
The ZD30 engine has suffered a poor reputation for premature failures including melting/cracking pistons and overboosting, largely due to some common issues. These engines run a variable vain turbocharger with boost controlled by the ECU, and to meet stringent European emission standards run an exhaust gas recirculation (EGR) system.
How do you set up a manual boost controller?
To set up or adjust a manual controller, close the needle valve and start the car. At idle, begin to open the needle valve until the turbo actuator arm drops away from its stop screw. Then just close it slightly until you see the arm lift and Then simply adjust your TDi Dawes valve to the amount of boost that you wish to run on.
How does manual boost work on a TDI?
The Dawes Valve is unique to TDi cars with Vacuum Controlled Nozzle Actuators and works in a similar way to a Ball Valve, but without the vent hole to release pressure for the Wastegate. Manual boost control is achieved by bypassing the ECU controlled Solenoid Valve to have total control via a Needle Valve from inside the vehicle.
