Nissan Patrol BMW M57 Conversion

Nissan Patrol M57 Swap — Engine Conversion Kit and Parts

FastMotion supplies the complete BMW M57 engine conversion system for the Nissan Patrol Y61, developed and refined through production build programmes. The Patrol M57 swap kit includes all engineered fabricated components for a clean installation using the factory Patrol gearbox, with ZF 8HP automatic conversion available as an additional specification. Our swap parts are in-stock, tracked and despatched worldwide.

Kit Contents and Scope

The FastMotion Patrol M57 swap kit contains a CNC-machined adapter plate matching the M57 bellhousing to the Patrol Y61 transfer gearbox, purpose-designed engine mounting brackets for the Y61 chassis, throttle cable or drive-by-wire adapter, exhaust routing components specific to the Y61 body, and all associated fitment hardware. The kit is designed to minimise custom fabrication work on-site, enabling a clean workshop installation with full technical documentation.

Engine Source and Specification

The swap kit is designed around the M57D30 engine in both single-turbo and bi-turbo configurations. FastMotion can supply a tested refurbished M57 engine alongside the swap kit as a combined package, or the kit can be used with a customer-sourced donor engine. Technical guidance on donor engine selection for specific output targets is provided with every order.

Electrical and Ancillary Integration

Wiring harness integration is a critical element of any engine swap and FastMotion provides a dedicated M57 swap wiring harness kit alongside the mechanical components. The kit provides simplified ECU integration, correct CAN bus wiring and all connector assemblies required for clean electrical installation without splicing into the vehicle's existing loom.

Frequently Asked Questions

Is the M57D30 or M57D40 recommended for the Patrol swap?

The M57D30 is the standard recommendation for the Patrol Y61 swap due to its physical dimensions, wide parts availability and proven reliability in this application. The M57D40 is a larger displacement variant with higher stock output but is physically longer and requires additional fitment considerations. FastMotion recommends the D30 for most Patrol builds and can advise on D40 fitment for specific applications.

Can the Patrol M57 swap be combined with the original Patrol transfer case?

Yes. The FastMotion swap kit includes the transfer case adapter components required to retain the factory Patrol transfer case with the M57 engine. This maintains the Patrol's dual-range system and preserves the original drivetrain gearing. The ZF 8HP conversion option modifies this arrangement and includes alternative transfer case interface components.

What exhaust system is required for the M57 in the Patrol?

FastMotion supplies a purpose-made exhaust manifold to downpipe system for the Patrol Y61 M57 installation. The exhaust routing is designed around the Y61 body and chassis to avoid any interference with vehicle systems or underbody components. The exhaust system is included in the full swap kit or available separately for customers who have already sourced other components.
