Jaguar XK Engine

Race Engine Manufacture:
Colour Anodisers Motorsport Engineering Services

The famed Jaguar XK engine was introduced in 1949 and produced until 1993. It was a double overhead camshaft inline 6 cylinder engine of 3.4 litres which in its original form developed 160 bhp increasing to 210 bhp  with the C-Type head as raced at Le Mans, The larger 3.8 Litre version was released in 1958. It was fitted with cast iron sleeves and bored to 87 mm and produced up to 265 bhp.

We have developed and built Jaguar XK race engines for many disciplines including historic circuit racing, speed hill climbing, fast road and drag racing.

We can produce a reliable power output of up to 600+bhp and 500 ft.lbs.of torque from the Jaguar 3.8 litre XK engine. Andy has spent vast amounts of development time on our flow bench to ensure maximum flow cfm is achieved yet without affecting inlet charge  velocity and these factors are tailored to the customer’s racing application, Andy also uses 1.50 inch bronze tappet guides on all our XK Jaguar big valve performance cylinder heads, which is a vast improvement on the original.

When the XK race engine is using Weber carburettors these are comprehensively modified to increase flow. We can also fit Lucus mechanical injection if required. This is expensive but is the preferred option for ultimate power, response and performance.

When the XK engine is to be highly modified for race circuit application steel step liners are always fitted to our cylinder blocks replacing the original cast ones.
