In response to demand from enthusiastic owners of the 406/416 models we have developed a bespoke turbo conversion kit for these models.
The kit includes; turbo, stainless steel exhaust manifold, stainless steel exhaust elbow, modified water rail, header tank, modified rocker cover, modified air feed pipe work, oil feed & return & all necessary gaskets as well as 50mm machined lifting blocks to raise the cab.
Fitting a turbo to these engines vastly improves the driveability of the Unimog. Because of the torque increase fewer gear changes are necessary especially when tackling an incline.
Power loss at high altitudes is reduced in comparison to a non-turbo engine.
There is also an improvement to fuel consumption compared to the normally aspirated engine.
We recommend replacing the injectors with a set which have the correct spray pattern to match the turbo. A set of 6 injectors typically costs £360+VAT.
Depending on the condition and type of injection pump fitted it is possible to adjust the fuel delivery to match the turbo or for even better results we can recalibrate your own injection pump to optimise performance.
For optimum results we recommend that all power upgrades are carried out in our workshop as some symptoms can be misdiagnosed by inexperienced mechanics.
The procedure we follow includes:
-Test drive vehicle.
-Thorough check over of engine including turbo, air pipe work, fuel lines etc.
-Adjust valve clearances as necessary.
-Check and adjust timing.
-Remove & test injectors.
-External check of injection pump and throttle linkage.
-Compression test engine.
