In recent years Rover car engines were part of the MG Rover Group. Land Rover was actually the company’s biggest seller throughout the 1950s, ’60s and ’70s), as well as the P5 and P6 saloons equipped with a 3.5L (215ci) aluminium V8, the design and tooling of which was purchased from Buick, and pioneering research into gas turbine fuelled vehicles.
Rover engines are offered at enginesandgearboxes.co.uk as used, reconditioned or secondhand and are available worldwide.
The Rover V8 engine
The V8 engine is a compact V8 internal combustion engine with aluminium cylinder heads and cylinder block, originally designed by General Motors and later re-designed and produced by Rover in the United Kingdom.
The initial Rover version of the engine had a displacement of 3528 cc. It used a sand-cast (rather than pressure die-cast) block, pressed-in iron cylinder liners, and a new intake manifold with two SU carburetors.
The Rover engine was heavier but stronger than the Buick engine, with a dry weight of about 170 kg (375 lb). It was first offered in the 1965 Rover P5B saloon, initially making 160 hp (DIN) (118 kW) @ 5200 rpm and 210 ft·lbf (285 N·m) of torque @ 2600 rpm on 10.5:1 compression.
Land Rover used a 3.9 L (3946 cc) version of the Rover V8 through the 1990s. Revised in 1995 (and thereafter referred to as a 4.0 to differentiate it from the earlier version, although displacement remained the same at 3946cc) with a new intake and exhaust system, extra block ribbing, revised pistons, and larger cross-bolted main-bearings. The 1995 4.0 produced 190 hp (142 kW) and 236 ft·lbf (320 N·m).
Production of the 4.0 ended in 2001. The final version of the engine, used in the Land Rover Discovery, produced 188 hp (140 kW) at 4750 rpm and 250 ft·lbf (339 N·m) at 2600 rpm.
The K-Series engine is a series of engines built by Powertrain Ltd, a sister company of MG Rover. The engine was built in two forms; a straight-4 cylinder , available with SOHC and DOHC, ranging from 1.1 L to 1.8 L, and the KV6 V6 variation.
The engine was introduced in 1.1 L single overhead cam, and 1.4 L dual overhead cam versions. The engines were unique in being held together as a sandwich of components by long through-bolts which held the engine under compression.
These two types of head that were bolted to the common block were designated K8 (8 valves) and K16 (16 valves). This allowed more power to be developed without compromising low-speed torque and flexibility.
The VVC system constantly alters the cam period, resulting in a remarkably flexible drive – the torque curve of a VVC K-series engine is virtually flat throughout the rev range and power climbs steadily with no fall-off whatsoever until the rev limiter kicks in at 7,200 rpm. The 1.8 litre versions are often used in kit cars and are starting to be used in hot rods.
Rover models are the 200/25, Streetwise, 400/45, 60, 80, 95, MG ZS, MG F, MG TF, Caterham Seven, 105, 2200, 3500, 2300, 2600, 2400, 100 and more.
