The Land Rover Discovery II is one of the most beloved modern classics in the 4x4 world. Its design is timeless, its off-road ability unquestioned—but owners know the weak link has always been under the hood. The original Rover V8 is charming in sound but notorious for overheating, head gasket failures, and a lack of power by modern standards.
That’s where the LS swap comes in. By replacing the Rover motor with a modern GM LS V8 and pairing it to a 6L80 automatic transmission, you completely reimagine what a Discovery II can be: reliable, powerful, and ready for daily use or adventure.
Project Pioneer: A Case Study
Our 2000 Land Rover Discovery II, known as Project Pioneer, is a perfect showcase of what’s possible with this kind of transformation. The heart of the build is a 400hp GM LS engine with a 6L80 transmission—a combination known for smooth, effortless torque and bulletproof reliability.
The swap began with removing the tired Rover drivetrain and preparing the engine bay for its new occupant. Tight clearances meant custom mounts, stainless steel exhaust routing, and precision fitment. The goal wasn’t to make it work just once, but to make it fit as if it belonged there from the factory.
Cooling the Beast
One of the most critical upgrades in any LS swap is the cooling system. For Project Pioneer, we installed an LS conversion radiator with twin electric fans and re-engineered the plumbing with high-flow hoses, reservoirs, and fittings. The result is a Disco II that stays cool even when worked hard—solving one of the biggest headaches of the original Rover V8.
Electrical Confidence
The Discovery II’s stock wiring is deeply integrated into the vehicle, but that wasn’t a roadblock. Instead of chasing gremlins, we turned the challenge into an opportunity. A Powertune digital dash now provides accurate, modern readouts, while custom harnesses and adapters ensure the GM ECU communicates seamlessly with the Land Rover systems. What once was a liability is now a strength.
The Transformation
What you end up with is a Discovery II that finally lives up to its potential:
Effortless power from a modern LS engine
Reliable drivability for road trips, commutes, or off-road treks
Upgraded cooling system that eliminates overheating worries
Modern electronics and digital dash for accurate information and peace of mind
Why an LS Swap is the Best Upgrade for a Discovery II
For owners who love the look and capability of their Disco II but are frustrated with the weak and unreliable factory engine, an LS swap is the ultimate solution. It’s not just a repair—it’s a rebirth. It transforms the Discovery into a reliable, powerful, and exciting daily driver that retains all of the Land Rover’s soul but with none of the compromises.
Project Pioneer stands as proof: the Discovery II doesn’t have to stay stuck in the past. With the right swap, it becomes the vehicle it always should have been—capable, dependable, and fun every time you turn the key.
