Petrol Engine Options

Land Rover 4.0V8 – 185HP

The Rover V8 engine is a compact V8 internal combustion engine with aluminum cylinder heads and cylinder block, originally designed by General Motors and later re-designed and produced by Rover in the United Kingdom. This engine was used in several Land Rover vehicles, including early Discovery and Range Rover models. This is the exact engine you will find in 1997 NAS Defenders for example with 185HP rating.

LS3 – 6.2L – 430HP – 425 lb-ft

The LS3 is filled with components designed for high performance and longevity. The aluminum block is filled with a sturdy reciprocating assembly that combines with L92-type rectangular-port heads to deliver a 10.7:1 compression ratio. As the standard engine in the fifth-generation Camaro SS and C6 Corvette, the high-revving, deep-breathing LS3 6.2L is poised to go down in history as one of Chevrolet’s best and most versatile engines.

LT1 – 6.2L – 460HP – 465 lb-ft

The LT1 is architecturally similar to the LS family of engines, but with a unique block casting, cylinder head design, oiling system and more. The LT1 is offered with a wet-sump or dry-sump oiling system. Introduced on the seventh-generation Corvette Stingray, the LT1 6.2L opened the next chapter in the long, historic legacy of the Small-Block engines.

LT4 SUPERCHARGED – 6.2L – 650HP – 655 lb-ft

Engineered for supremacy, the LT4 features a 1.7L Eaton R1740 TVS supercharger, which spins at up to 20,000 rpm. That’s enough to generate more than 9 pounds of boost and help produce 650 horsepower and 650 lb.-ft. of torque. Supercharged power, as the heart of the Corvette Z06, the supercharged LT4 6.2L SC is one of the most powerful engines ever offered by Chevrolet.

LC9 – 5.3L – 315HP – 315 lb-ft

The LC9 is a technically advanced small-block V8 engine that delivers a great balance of power, torque and efficiency. Variable valve timing helps the 5.3L optimize performance, efficiency and emissions, while GM’s Active Fuel Management cylinder deactivating technology helps improve fuel economy in certain light-load driving conditions.

The 5.3L is powerful, but delivers exceptional refinement to go with great strength. Quiet features built into the engine are complemented by an improved engine cradle and mounting system. These help reduce vibrations transmitted through the chassis and into the passenger compartment.

LV3 – 4.3L – V6 – 285HP – 305 lb-ft

The LV3 V6 engine is produced by General Motors for use in pickup trucks. It is part of GM’s 5th-generation Small Block engine design that’s named EcoTec3 in pickup trucks, replacing the 4th-generation Small Block engine family known as Vortec. The launch of the EcoTec3 engine line, including the 4.3L V6 LCV, coincides with the launch of the all-new 2014 Chevy Silverado and 2014 GMC Sierra. The 4.3L V6 LV3 is based on the V8 versions of the Gen V family, but with two fewer cylinders – a design lineage that dates back to the previous 4.3L V6, which was itself a Gen-II small block with a pair of cylinders removed.

Diesel Engine Options

Cummins R2.8 Turbo Diesel – 161HP – 267 lb-ft

The R2.8 turbo-diesel engine is the ISF2.8 four-cylinder diesel engine, the smallest and lighter engine out of the ISF engine family. The Cummins ISF2.8 is the modern engine that combines two main qualities – the power and compactness. The Cummins R2.8 engine has cast iron cylinder block with sleeves, which could be replaced. That results in less material consumption and higher strength. The simple and cheap material provides low cost, reliability and repair possibility.

The engine has the high-end technology fuel system – electronically controlled Common Rail fuel injection. The high-pressure fuel pump is mounted on the front end of the engine. It is driven by camshaft through the gear. The ISF2.8 has turbocharger HE 200 WG without an intercooler. The engine is equipped with start-up relief devices at low temperatures. An electric spiral is provided for heating the air in the intake manifold.

Xerbera 3.0 V6Td Turbo Diesel – 240HP – 420 lb-ft

With the three liters of displacement, the V-6 registers 240 horsepower and 420 lb-ft of torque; that’s more torque than some V8 petrol engines produce. Even more impressive are the engine’s fuel economy ratings – 30 MPG.

The 3.0 V6Td is paired with the ZF engineered ‘TorqueFlite 8’ eight speed automatic transmission for added efficiency. It has an electronically limited 4,800 rpm max engine speed, though wide-open up-shifts occur close to 4,000 rpm. Engine’s are manufactured by VM Motori in Cento, Italy and are used in Ram 1500 trucks as well as Jeep Grand Cherokees.

Transmission Options

Strengthened GM six speed automatic 6L80E, super duty 6L90E transmission or 4 speed 4L80E.

Introduced in late 2005 to become the 6-speed replacement for the 4-speed transmissions such as the 4L60E. The early release of this product line was introduced in Cadillacs and Corvettes, but before long it became mainstream for GM’s light duty pickup and SUV lines.

GM 6-Speed 6L90E Hydra-Matic Automatic Transmission

The Hydra-Matic 6L90E is a six-speed automatic transmission produced by General Motors for use in rear-and rear-biased all-wheel-drive vehicles with a longitudinal powertrain orientation. Developed in-house by General Motors, the Hydra-Matic 6L90E is part of the 6LXX family of fuel-saving, electronically controlled six-speed automatic transmissions that succeeded the 5LXX family.

The modular design of the Hydra-Matic 6L90E is shared with variants rated for different torque levels to accommodate various engines and vehicle applications. All versions share a unique output gearset configuration that enables it a wider range of ratios than a conventional planetary gearset automatic transmission. This allows the transmission to be tailored for optimal fuel economy while delivering excellent acceleration traits. The wide overall ratio spread of 6.04:1 allows a “steep” first gear, as well as a very “tall” overdrive top gear for low-rpm highway cruising.

The heavy-duty T56 Super Magnum Manual Transmission

The T56 is a high-torque capacity TREMEC six-speed manual transmission designed for custom, retro-fit installations with Chevrolet Performance crate engines such as LT1 and LT4. Brute strength – featuring a 700 lb.-ft. maximum torque capacity, the T56 has an exterior case similar to the fourth-generation F-body transmission. The T56 also includes stronger, high-capacity gear sets, input shaft and output shaft used in the TREMEC TR6060.

8-Speed ZF 8HP70 Automatic Transmission 
Innovation by reduction: efficiency, perfected
With the development of the new 8-speed automatic transmission by ZF, the focus was not on the number of speeds but rather on the minimization of fuel consumption. The new 8HP 8-speed automatic transmission, which was designed to be more lightweight, sets new standards for flexibility, efficiency, and economy. It is an excellent example of how the power of innovation can create a new classic design.


New gear set design: four planetary gear sets and only five shift elements minimize the drag loss and increase the transmission efficiency.
Optional hydraulic impulse oil storage (HIS) opens up the possibility of the start-stop function and increases the fuel savings potential.
Integrated transmission control unit with extremely quick response time.
Basic transmission can be combined with multiple power take-up elements including the torque converter, the hybrid drive, and the integrated power take-up element.
Full hybrid compatibility: on the basis of the parallel hybrid concept, mild, full and plug-in hybrid systems can be implemented with the basic transmission of the 8-speed automatic transmission.
The transmission is compatible with the following all-wheel-drive concepts: All-wheel drive center differential integrated, integrated all-wheel drive system (IAS©), hang-on all-wheel-drive
For input torque range from 300 to 1000 newton meter
Multi disk separation of brakes
Optimized cooling: less cooling oil for low system pressures, more cooling oil for high system pressures
Automatic idle shift system at vehicle standstill and engaged service break (stand-by control)
