We invested 2 years into developing our N54 Top Mount kit - design updates and validation ensure our customers get a reliable kit that performs.

Turbo position, Wastegate position, O2 sensor positions, Oil Drain and Oil Feed have all been refined for peak performance and maximizing clearances from hot parts (which is a common problem in other top mount kits).

Stainless steel 2-piece tubing and wastegate dump pipe (recirculating or open dump), crafted with mandrel bends, tig welds, and cnc flanges.

Seeing the failures of other top mount kits, we made a point to put upfront work into an engineered oil drain system.

Hot-side parts positioned to allow an oil drain path with ample clearance to hot parts.

Kit designed with ease of installation and commonized components in mind. Our layout allows use of stock motor mount, coolant manifold, hoses/pump.

Manifold design allows for easy access to hardware and kit configuration allows for easy installation and service of all components.

All oil and coolant connections at the turbo are AN fittings, making a turbo swap quick and easy.

Our unique tubing/wastegate pipe configuration allows the customer to change from recirculating to open dump, and vice versa, with just the swap of the wastegate pipe. Cheap and easy upgrades.

As it's crucial to use new hardware during a kit install and ensure correct length of studs, we include manifold to turbo studs, OEM manifold to head studs along with copper nuts with each kit for ease of installation.

Two patents pending - Utility patent on the unique configuration of the hot-side parts.

Also a separate design patent on the manifold itself.

Engineered to perform, and to be seen.
