Here at Precision Sport Industries, we thought we had seen it all for the N54 platform. This was until we were handed the brand-new Doc Race bottom-mount turbo kit! This new kit is the sister to the extremely durable and newly revised top-mount kit that Doc Race has been famous for. From one-piece manifolds to custom billet accessories, Doc Race truly took both of these kits to the next step. Now, before we dive too deep into power modifications, I highly suggest checking out our previous post titled “It’s Time to Have that Talk – n54 Reliability,” where we cover known issues and the solutions that we take to help make your car make power reliably. So now, after doing that… let’s talk power.
The Doc Race N54 Top Mount Single Precision Turbo Kit’s reputation speaks for itself. As the current N54 single turbo record-holding system, you are guaranteed to make power. As you open the box, you quickly realize that this kit goes above and beyond and keeps every step of the installation process in mind. Time and time again, we see the smaller bits of turboing a car go overlooked. Doc Race takes the extra time to include all v-bands, hose clamps, gaskets, etc. to make the installation process go as smoothly and quickly as possible. The largest features of the kit include the chosen T4 turbo, twin 40mm Turbosmart wastegates, and their revised turbo manifold.
As of late September, what was once a twin-scroll three-part unit is now a beautifully welded, ceramic-coated single-piece manifold. This revision helps limit potential exhaust leaks in the future while maintaining the same twin-wastegate placement. The only modifications not included with the kit are the boost controller, a tune, and an upgraded fuel system for cars aiming for higher horsepower. To get the best performance from your vehicle, we recommend pairing this system with the GFB boost controller! This kit is a tried-and-true method for making N54 power.
