Nissan Patrol M57 and ZF 8HP Complete Powertrain Conversion
FastMotion supplies the complete M57 diesel engine and ZF 8HP automatic transmission conversion for the Nissan Patrol Y61. This combined powertrain upgrade replaces both the factory engine and gearbox with the BMW M57 inline-6 diesel and ZF 8HP eight-speed automatic, delivering a substantial increase in power output, transmission capability and overall drivetrain refinement compared to any factory Patrol configuration.
What the Combined Conversion Delivers
The M57 and ZF 8HP combination in the Nissan Patrol Y61 transforms the vehicle's capability profile. The M57D30 in standard form produces substantially more power than the ZD30 or TD42 engines, with significantly better thermal management under sustained load. Adding the ZF 8HP provides eight forward ratios — compared to four or five in factory configurations — with a wide ratio spread that delivers optimised gear selection both on technical off-road terrain and at motorway cruising speeds. The combination results in a Patrol that is more capable, more economical at highway speeds and more reliable across all use cases.
Conversion Components Supplied
FastMotion supplies the M57 engine conversion kit and ZF 8HP conversion adapter as a coordinated package. Components include the M57 adapter plate for the Patrol chassis, ZF 8HP adapter plate and starter conversion, transfer case interface components, the ZF 8HP standalone controller kit, paddle or sequential shifter options, and oil cooling system for the transmission. The complete wiring integration kit and cooling system upgrade components are available alongside the mechanical conversion package.
Frequently Asked Questions
Can I do the M57 swap and ZF 8HP conversion at the same time?
Yes, and this is the recommended approach. Performing both conversions simultaneously reduces total labour time compared to separate installations and allows all drivetrain components to be fitted and aligned together before the vehicle is returned to road use. FastMotion coordinates all kit components as a combined package with unified technical documentation.
Does the ZF 8HP conversion affect the Patrol's low-range capability?
The ZF 8HP conversion retains the Patrol's transfer case for four-wheel drive and low-range operation. Low-range gearing is preserved, and the combination with the ZF 8HP's first and second ratios creates an exceptionally low effective crawl ratio for technical off-road use. This is one of the most significant capability improvements that the combined conversion delivers.
What ZF 8HP variant is recommended for the Patrol M57 build?
The ZF 8HP45 is the standard specification for Patrol M57 builds at stock to mildly tuned output levels. For builds targeting above 380 Nm at the transmission, the ZF 8HP70 is recommended. FastMotion can advise on the appropriate specification for your power targets and intended use case before purchase.
