BMW M57 Top Mount Turbo Kits

Top-exit exhaust manifolds and complete top-mount turbo systems for M57 swap builds.

Top Mount Turbo for Swap and Off-Road Builds

A top mount configuration positions the turbocharger above the engine — offering packaging and clearance advantages in swap builds and custom platforms. FastMotion top mount kits are designed for use with the BMW M57 and are compatible with the intercooler systems in the FastMotion catalogue.

BMW M57 Top-Mount Turbo Kit — High-Position Turbo Conversion System

FastMotion supplies a complete BMW M57 top-mount turbo conversion system, relocating the turbocharger from its standard position to a high-mount configuration on the exhaust manifold. This conversion optimises airflow geometry, reduces turbocharger inlet temperature, shortens boost pressure routing and enables the use of larger turbocharger specifications that cannot be packaged in the standard M57 underbay position. The kit is a core component of high-output M57 performance builds.

Kit Contents

The FastMotion M57 top-mount turbo kit includes the purpose-fabricated exhaust manifold providing the top-mount turbocharger interface position, turbocharger mounting bracket assembly, downpipe with EGT sensor provision, oil feed line for the turbocharger, oil return line kit, V-band clamp assembly and all fitment hardware. The alternator relocation kit is a required companion component in most M57 top-mount installations and is available as an addition. The turbocharger itself is supplied separately and can be specified from the FastMotion turbocharger range based on your output target.

Performance Benefits

The top-mount turbo position delivers measurable improvements in intake air temperature management, reduces heat soak from exhaust gas routing to the turbocharger inlet and allows larger turbine housing specifications without the physical constraints of the standard underbay position. In combination with the FastMotion water-to-air intercooler kit, the top-mount system provides the thermal management infrastructure for reliable outputs in the 320 to 380 bhp range.

Frequently Asked Questions

Is the alternator relocation required with the top-mount kit?

Yes, in the majority of M57 configurations and all Patrol Y61 applications. The standard alternator position conflicts with the top-mount exhaust manifold routing. FastMotion supplies the alternator relocation kit as a dedicated companion system with OEM and water-cooled alternator variants for different application requirements.

Which turbocharger is recommended with the top-mount kit?

The top-mount kit is designed to accept a range of turbocharger specifications. For 300 to 340 bhp builds, a ball-bearing hybrid turbocharger is the standard recommendation. For 340 to 380 bhp targets, a larger ball-bearing unit with optimised turbine housing is appropriate. FastMotion can specify the correct turbocharger for your output target and usage profile based on the top-mount system configuration.

Does the top-mount kit require engine bay modifications in a Patrol Y61?

The kit is designed to fit within the Patrol Y61 engine bay with standard M57 swap dimensions. Some builds may require bonnet insulation modifications or minor heat shield work. FastMotion provides fitment guidance specific to the Patrol Y61 application with every top-mount kit order and can advise on build-specific requirements.
