The factory HT60 on the Cummins N14 and 855 engines has a unique flange pattern and abnormal mounting orientation that makes it very difficult to retrofit a more modern upgraded turbocharger.
With this in mind, we set out to create an upgrade that was a direct replacement from an installation stand point.
Depending on the original spec and horsepower out put, your N15/855 could have had a multitude of different chargers from the factory, we have listed them below.
As you can see above, our N14 upgraded turbo has a 2MM Larger Compressor Wheel Inducer and 7MM Larger Turbine Wheel Exducer over the largest stock N14 turbo. This makes for a great upgrade over the stock turbo. Add a little fuel and you will certainly have a little more pulling power!
