Chelsea’s S4 GU Nissan Patrol Upgrades

You’ve never seen a GU Patrol like this before!

Setting the Stage

Every great 4WD build starts long before the first bolt is turned. For Chelsea Humphrey and Jonesy, this S4 GU Patrol project began with a full strip-down, prep, and plan.

As the Enhanced Offroad team shared on Instagram:

“Chelsea and Jonesy getting a warm-up in before tackling the Jimny lift kit 💪 — removing the GU’s tow bar and other parts before it headed off for rust proofing. Every build starts with the prep work, and this one’s no different. Big things coming for both rigs 👀.”

That behind-the-scenes work is what separates an average build from a great one. Prep is everything — and it’s the reason Enhanced Offroad Solutions builds perform as good as they look.

The Vision

The goal for Chelsea’s Patrol was simple:
Create a GU that’s tough, street-legal, and perfectly balanced — a machine that drives as good on-road as it performs off-road.

This build isn’t a garage experiment. It’s a professionally engineered setup sponsored and supported by Enhanced Offroad Solutions, using industry-leading components and proven fabrication techniques to bring the vision to life.

Suspension & Geometry — The Foundation of Strength

You can’t build a powerhouse Patrol without a rock-solid suspension system.

This GU runs a 4-inch street-legal lift kit, engineered for stability, travel, and compliance.
The geometry has been completely re-worked with a long-arm conversion — giving the chassis the articulation and axle control it deserves.

To handle serious punishment on- and off-road, the build includes:

• Hybrid Radius Arms — combining strength and flex for greater control over uneven terrain.
• Superior Engineering Billet Arms — machined to perfection for ultimate durability.

The end result? A suspension setup that’s not only compliant but also capable of handling brutal terrain with comfort and confidence.

Wheels, Tyres & Brakes — Grip Meets Control

Rolling on KMC Wheels wrapped in 35” Maxxis Razr MTs, this Patrol strikes the perfect balance of aggression and functionality.

The 35s provide massive contact area and off-road bite, while still maintaining a street-legal stance thanks to careful fitment and guard work.

Stopping power comes from a Bendix Ultimate Brake Upgrade Kit, ensuring this heavy-hitter pulls up just as hard as it launches.
With the added weight of the conversion and lift, upgraded brakes weren’t optional — they were essential.

The Heart of the Beast — BMW M57 Diesel Conversion

Here’s where things get truly wild.

Under the bonnet sits a BMW M57 3.0-litre turbo-diesel — the same powerplant found in high-performance European models, now breathing new life into one of Australia’s toughest off-road icons.

Why the M57?
Because it’s one of the most capable and reliable diesel engines ever made:

• Smooth, linear torque that’s ideal for towing and climbing.
• Proven reliability under heavy load and long-distance touring.
• Exceptional tuning potential, allowing massive torque gains without sacrificing drivability.

When paired with the GU’s drivetrain and upgraded braking system, the result is a Patrol that feels refined on-road yet unstoppable in the bush.

This isn’t just a swap — it’s a transformation.

Tuned Y62? Not Even Close.

We’ve built and tuned our fair share of Y62 Patrols, and while the 5.6-litre V8 packs plenty of punch, even the best-tuned Y62 can’t keep up with the brute force of this M57-powered GU.

Where the Y62 needs revs to find its powerband, this diesel monster delivers instant torque from idle.
Hit the throttle, and it digs in — no lag, no hesitation, just pure grunt.

For touring, towing, or technical terrain, this GU has the advantage every time.
It’s a different kind of power — usable, reliable, and relentless.
