KIT DEVELOPMENT
We've spent the past two years developing our N55 top mount kit, and it shows. The result is a kit that is not only engineered to perform, but keep OEM-like reliability.
Turbo position, Wastegate position, Oil Drain and Oil Feed have all been analyzed for ideal placement in regards to performance, reliability, service/tool access, and more.
CAST MANIFOLD
Building off our experience from our other BMW kits, this N55 top mount manifold hits all the marks. Twin-scroll, CFD flow analyzed, cast manifold to ensure the best balance of quick spooling and high HP capability, along with durability. All interfacing features are machined, creating perfectly flat mounting flanges, with very tight tolerances for a perfect fit on every kit. No other competitors have the engineering skillsets to compete with us here.
STAINLESS TUBING
Stainless steel 2-piece tubing and wastegate dump pipe (recirculating or open dump), crafted with mandrel bends, tig welds, and cnc flanges.
OIL FEED
Stainless braided oil feed hose, billet engine fitting with o-ring and bolt, and required fitting to the turbo oil feed
ENGINEERED OIL DRAIN SYSTEM
Just like our other BMW kits, we made a point to put upfront work into an engineered oil drain system.
Hot-side parts positioned to allow a smooth oil drain path with ample clearance to hot parts.
OIL DRAIN
Stainless braided -10AN line, and stainless AN tig welded fittings at the turbo and engine, ensure a leak-free and durable oil drain system. Also improves serviceability of the turbo for those of us that like to swap turbos.
COMMONIZED COMPONENTS
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.
CHARGE PIPE
Mandrel formed 2.5" aluminum tubing with an 1/8npt bung, and custom silicone couplers at each end.
MANIFOLD HARDWARE
As it's crucial to use new hardware during a kit install, we include manifold to turbo studs, manifold to turbo copper exhaust nuts, and manifold (donut) gaskets with each N55 F-Chassis Top Mount Kit for ease of installation.
PATENTS PENDING
Two patents pending - Utility patent on the unique configuration of the hot-side parts.
Also a separate design patent on the manifold itself.
Just like with our N54 Bottom & Top Mount Kits, you have choices. Choose from over 30 different turbochargers from the best manufacturers. Now offering Pulsar turbos options for the N55 Top Mount kit.
