Nissan/Cummins 5.0 548rwhp/930rwtq!

Pretty big numbers and shows just how restrictive the "made for emissions" turbo is. It says the stock turbo was at 2:1 drive pressure which is good for emissions, but bad for the engines longevity. Same can be said for the 6.7L turbo. Adding a fixed geometry that is correctly sized to the amount of fuel being added not only reduces drive pressure, but also allows you to make more reliable power with lower temps. Adding power does not always mean decreased reliability if done right.
