On the 2nd Gen trucks the turbocharger is mounted on the middle of the exhaust manifold while the 3rd and 4th gen is located at the back. In theory, the exhaust pulse in the central location is much more efficient for turbo spool. This location is much easier to get to and makes future modifications a lot easier. Not only being less restrictive than the stock 3rd and 4th Gen manifold, you will be installing a more reliable NON-VGT turbocharger in place of the stock unit. There are many options to choose from so if you need help on deciding which turbo is good for you, please don’t hesitate to email us.
