  • Manifold/downpipe/dumppipe arrangement advantages:

    • Efficient flowpath with consistent boost control

    • Keeps wastegate cold-side in cool air for reliability and easy spring changes

    • Places O2 sensors in ideal location to keep sensor body temps down to prolong life and allow easy access for service.

    • Fewest joints and welds for leak free, trouble free operation

    • Provides ample clearance from all hot-side components

    • Allows use of stock motor mount isolator


Patent Pending

The unique configuration of the manifold, turbo, wastegate, downpipe, and wastegate dump pipe is USPTO patent pending

Cast Manifold

Similar to our N55 manifold, we designed the N54 manifold to not sacrifice on anything. Maximum bend radii, flow simulation, stress analysis, thermal cycling analysis… This manifold design takes an OEM approach to making huge power.

Intake Components

In order to create the most efficient flow path into and out of the compressor, custom silicone tubing, combined with mandrel formed aluminum tubing is used.


EXHAUST

Stainless steel downpipe and wastegate dump, crafted with mandrel bends, tig welds, and cnc flanges.

Factory Fit and Finish

Clean engine bay, keeping the heat down low and out of the way, just like the factory intended. Lots of room for a generous sized air filter (important to minimize pressure delta across filter, as small filters can create pressure drops and increased turbo bearing wear, shortening the life of your turbo). Note - it is possible to keep the coolant overflow tank in original location, we just prefer moving it to give a cleaner look, and allow more airflow on turbo side of engine.


FITMENT

Currently verified on E8X and E9X, both AWD and RWD
