Taurus marketed a wide range of quality tested equipment for improving the performance, safety and comfort.

The vast majority of their equipment they sold through retail outlets, such as garages and accessory shops. In 1968 there were about 80 Taurus appointed agents and they were continuing to expand in that direction, saying that there were still wide gaps in our U.K. network which they were always seeking to fill satisfactorily. Sales Manager P. Surtees:

"We make no excessive stocking requirements of our Agents and aim to despatch orders with the minimum of delay rather than insist on their holding stocks of our entire range. Normal trade discount is 15% but, on appointment, the Agents discount structure applies."

They carried out reasonably extensive national advertising, and received their share of editorial publicity. All enquiries resulting from this were replied to promptly by Taurus.


Taurus had a separate workshop in Kent which deals with modifying engines and suspension to customers requirements and specifications on an individual basis.

Suspension / Handling

Suspension springs can be set to any given ride height, whether the car is to be used for rallying or race use. Other than this the suspension needs very little attention other than

Cylinder heads

Taurus are recognised as one of the leading companies in the field of cylinder head modification. Our wide range combines the latest developments and techniques with the finest workmanship and finish and represents the best value obtainable in tuning equipmant.

GO-AHEAD cylinder heads are the first step in obtaining improved performance from the standard engine. Latest design and top quality workmanship ensure maximum power whilst retaining standard valve sizes.

CONTINENTAL cylinder heads are designed to be used with other Taurus equipment and are recommended for those who require spectacular road performance. These heads are more extensively modified than the GO-AHEAD and in general employ larger valves.

Further stages of modification are available, up to full race specification. All Taurus cylinder heads are fully assembled before delivery and can be easily fitted. Kits include all necessary gaskets etc., and detailed fitting instructions.

Race heads can be produced for any of the above to special order and are manufactured to customers requirements- race, raIly, autocross etc.


Taurus Camshafts are designed and developed to suit the individual models for which they are recommended. The profiles of these camshafts are extremely sophisticated and are all mathematically computerized, using sine-wave acceleration palterns, to give minimum valve mechanism stress. Each profile is cut from a master 5 times actual size to ensure complete accuracy within .0002" on the shaft.

TAURUS SPORTS CAMSHAFTS are designed to glve the best possible increase in power in the middle and top rev range, without significantly changing low speed flexibilility and aee thus ideal for normal road use. When used in conjunction with other engine modifications, they will give an increase in power over the entire rev range, particu1arly at the top end.

TAURUS SUPER SPORTS CAMSHAFTS are designed primarily for high power output and therefore some loss of low speed torque is inevitable. They are best used in conjunction with other engine modifications and wi11 produce a high output for competition, while still being usable on the road.

TAURUS COMPETITION CAMSHAFTS give the ultimate in power. When used in engines otherwise suitably modified, they produce highly competitive power outputs and have been responsible for numerous racing successes. Because of the peaky power curve and the stresses which are p1aced on the valve gear, it is not recommended that these cams be fitted to cars used for day to day motoring.

Oil Temperature Thermostat

Oil Temperature Thermostat; Taurus Oil-statOil-stat for use with oil coolers. Optimum engine oil temperature in all weather conditions.

Correct control of the temperature of your engine oil is vital to the life and efficiency of your engine -even more so than the water temperature. Oil which is cold or running below the proper operating temperature causes

The fitting of an oil cooler increases the risk of overcooling, particularly in cold weather.

To eliminate these dangers Taurus have developed the OIL-STAT, which will thermostatically control the temperature of the engine oil. The Taurus OIL-STAT has been warmly welcomed by experts in the field of lubrication and represents a major breakthrough. It is available as a separate unit for use with existing oil coolers and has also been incorporated into the highly successful range of Taurus Oil Coolers to provide the finest and safest oil temperature control equipment currently available.

With the invention of the OIL-STAT, it is now possible for your car to have the degree of control over oil temperature which hitherto has only been available on aircraft engines.

To enable you to maintain supervision of your engine oil temperature, Taurus have made provision for an oil temperature gauge take-off in the OIL-STAT. A Smith's temperature gauge kit to fit this is available at a price of £3.10.0.


The TAURUS universal oil-stat consists of a precision die-cast and machined block which is fitted into the flexible pipes leading to the oil-cooler element. The blody of the oil-stat consists of a thermostatic element which acts as a full-flow bypass, bringing the oil-cooler into action progressively as the oil temperature rises. The oil temperature is maintained at the optimum level of 75°C, ± 5°C.

The TAURUS oil-stat gives you

The Taurus OIL-STAT can be fitted to cars already equipped with oil coolers; alternatively it can be fitted in conjunction with Taurus oil cooler kits, as listed below.

Thermostatic Oil Coolers

Each Taurus thermostatic Oil Cooler is specifically designed for the car it is to fit. The kit consists of a race-pattern ultra light-weight aluminium element with all the necessary mounting brackets for its easy fitting. The elements are designed for a maximum working pressure of about 150 psi. and have a bursting pressure of over 400 psi.

The lengths of high pressure, cotton-braid, reinforced hosing with oil resistant neopreen rubber lining are supplied ready fitted with quality cadmium plated connectors. Adaptors also supplied as required as are special aluminium sandwich plates which fit between the oil filter housing and bowl and are fully machined and supplied with all necessary rubber 'O' rings for effective sealing.

Kit Part No. 1R has 10 tube elements.

The Oil-Stat is a precision die cast aluminium unit which acts as a thermostatic valve.

Comprehensive fitting instructions are supplied with each kit, but all Oil Cooler Kits can be fitted at the Taurus Tuning Centre, at Taurus Agents throughout the country, or at any competent garage.
