Graeme Cooper Automotive provide HALTEC chips and tuning for all common rail Diesel engines (not just Land Rover). The Landrover diesel engines are of course our speciality offering a long and generally exemplary history.

The 2286cc 4cyl, ohv, indirect injection, diesel was first used in S2A, S3 and early 90 and 110s. A five bearing crank-shaft was introduced in 1980. We do not generally recommend attemping to upgrade this engine

The 200TDI (1990 - 1994) 2495cc, 4cyl, ohv, direct injection, diesel (nominally 2.5L). natural aspiration developed 85bhp at 4000rpm, 150 lb-ft at 1800rpm. The turbo version developed 107bhp at 3800rpm, 188 lb-ft at 1800rpm. This engine is still in common use as a hardy, reliable powerplant

300 TDi, turbo, diesel, inter-cooled (1994 - ). 2495cc, 4cyl, ohv, diesel (nominally 2.5L). 90.5mm x 97mm, 19.5:1 cr, 111bhp, 83kW at 4000rpm, 195 lb-ft, 265Nm at 1800rpm. This is a quieter, faster engine than the 200TDI. Many are poorly tuned and performance may be significantly improved using our tuning techniques.

The TD4 as fitted to the Freelander 1, like all electronic-controlled diesels can produce significant additional power and/or economy when correctly tuned.

The Td5, 2.5L diesel, 5-cyls, common-rail, direct injection, turbo-charged, intercooled, 2-valves/cyl, sohc produced 101kW at 4200rpm, torque 300Nm at 1950rpm. This engine is faster than either the 200 or 300TDI models, yet delivers excellent economy. This engine responds well to our performance tuning

The (BMW) TD6 3 litre 6cyl, ohv, turbo, intercooled, indirect injection diesel is especially good when fitted with the HALTECH Interceptor ECM.

The TDV6 is the latest diesel engine as fitted to the Range Rover Sport and Discovery 3. It can deliver up to 140 Kw with expert tuning.

Data quoted above is ex-factory performance. In reality, the level of tune and enhancements to the engine management systems are critical to achieving optimum performance - where Graeme Cooper Automotive offers particular expertise
