Looking for a way to transform your Mitsubishi Pajero with serious torque and reliability? The Pajero M57 conversion kit is one of the most popular swaps on the market. By pairing the legendary BMW diesel with your Pajero chassis, you get modern power, smooth performance, and a drivetrain that can handle anything from off-road trails to long-distance touring.
In this guide, we’ll cover everything you need to know about the Pajero M57 engine conversion, including mounts, wiring, cooling, exhaust, and transmission options.
Why Choose the BMW M57 for a Pajero Swap?
The BMW M57 3.0L diesel engine is known worldwide for:
High torque output (up to 286hp in stock form).
Strong aftermarket tuning support.
Proven reliability with proper maintenance.
Compatibility with modern transmissions like the 8HP.
For Pajero owners, Pajero M57 conversion kit means more pulling power, better drivability, and a massive upgrade over the stock diesel engines.
What’s Included in a Pajero M57 Conversion Kit?
1. Engine & Transmission Mounts
The kit provides custom Pajero mounting brackets for the M57. This eliminates guesswork and ensures the engine sits in the correct position. Transmission crossmembers may require small adjustments depending on your gearbox choice.
2. Plug and Play Wiring Loom
A pre-wired loom is available to integrate the BMW M57 with your Pajero. It’s labelled and simplified, making the installation process far easier. This means fewer hours of wiring headaches and faster installation at your workshop.
3. Instrument Cluster & Electronics
The conversion loom supports Pajero electronics. That includes the instrument cluster, ABS, traction control, and A/C. No dead gauges or hidden warning lights everything continues to function as intended.
4. Cooling System for Hot Climates
The stock Pajero cooling system isn’t enough for the M57 under load. The conversion kit comes with an upgraded radiator and intercooler package, sized for high ambient conditions. Perfect if you’re running in hot regions where cooling failures are common.
5. Exhaust Options
A ready fit downpipe is included, designed for the Pajero chassis. From there, you can adapt or fabricate the remaining exhaust system to your preference.
6. 8HP Automatic Transmission Compatibility
The BMW 8HP gearbox pairs beautifully with the M57. Our conversion kit includes CANbus integration and a pre-configured CAN display, giving you smooth gear shifts and a working gear indicator.
Pajero M57 Conversion kit vs Other Engine Swaps
Why choose the M57 over Toyota or Isuzu diesel swaps?
Stronger aftermarket support worldwide.
Cheaper parts availability across Europe.
Easier tuning options.
Better long-term reliability when serviced correctly.
This makes the M57 one of the most cost effective and performance oriented swaps for Pajero owners.
Is the Pajero M57 Conversion Kit Plug-and-Play?
Yes as close as a swap gets. With mounts, loom, cooling, and CAN display included, installation is straightforward. Some small fabrication (such as final exhaust routing or transmission mounts) may still be required, but 90% of the hard work is already solved.
