SPEEDTECH N54 BOTTOM MOUNT KIT
MANIFOLD/DOWNPIPE/DUMP PIPE 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
Don't be fooled by competitors, with their cheap single scrool (aka slow spool) manifolds, and poorly placed O2 sensors that do not even measure AFR of all cylinders (high risk of engine damage if injector issues occur on the cylinders that are not measured by the incorrect O2 placement.
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.
The unique configuration of the manifold, turbo, wastegate, downpipe, and wastegate dump pipe is USPTO patent pending
Stainless steel tubing and wastegate dump, crafted with mandrel bends, tig welds, and cnc flanges.
BILLET COOLANT MANIFOLD
Designed to maintain an efficient coolant flow path, and also be able to package 1000+HP turbos
STAINLESS BRAIDED OIL FEED
Our N54 Bottom mount oil feed utilizes a stainless braided hose, billet aluminum block fitting, fitting to turbo, and stainless hardware to create a reliable system.
Depending on turbo, either a stainless welded drain, or a billet aluminum drain block, custom high temperature silicone, and stainless hardware are utilized to create a free flowing and reliable system.
BILLET ALUMINUM PLUGS AND FITTINGS
Precision CNC machined plugs and fittings to ensure leak free connections
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.
MANIFOLD STUDS & NUTS
As it's crucial to install new hardware during a kit install and ensure correct size of studs, we include manifold to turbo studs, OEM manifold to head studs along with copper nuts with each kit for ease of install.

FACTORY FIT & 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 the original location, we just prefer moving it to give a cleaner look, and allow more airflow on the turbo side of the engine.
