Vauxhall XE 20- 285BHP

The standard 150BHP made these engines pretty potent in their day. As such the found their way in any number of kit car formats for use in rally, track day and sprint racing. Our top-spec XE engine delivers 285 BHP and fantastic torque characteristics. If you are serious about competeing with this engine you should seriously consider speaking to us.

Cylinder head.

Our measurements show a 14.9 % increase in flow (inlet) and 21.5% increase in exhaust flow. In standard form, this engine gives 150BHP. We also provide standard and big valve versions for this head.

Check out our CNCHeads website for this head


as part of our cylinder head development we are able to specify a matching set of camshafts which match the flow profile of the head. This helps us make the most of the available flow through the head and improves peak flow and torque across the rev range.


having a fully balanced and lightened crankshaft has a huge effect on the balance and responsiveness of the engine. We give the crankshaft the full treatment on our CNC crankshaft balancer. Check our crankshaft page .

Rods and Pistons

Over about 230BHP you will exceed the reliable limits of the existing rods and pistons. These are replaced with top spec items. We look carefully at the specification of these items to match the intended purpose so we’re not tied to one particular brand. Where necessary we make minor modifications to suit our needs. Again these items are fully balanced with the crankshaft.

ECU and fuelling.

This depends on budget and application . For instance for trackday purposes and basic twin webber carb and basic ECO setup will suffice. For top end racing applications we provide a puuka racing ECUsuch as a Motec 800 with custom mapping. We also provide 4 and 8 injector fuel injection. We also provide dry sump systems for serious racing applications.

Each of these engines is bespoke according application and budget. We don’t supply crated engines or “box shift” and build components from other vendors. When you talk to us about an engine you will receive all the attention deserving of a bespoke service. The results are exactly as we specify and ultimately measure on our dyno. We don’t make false promises on power. Come down and see the power YOUR engine makes on the dyno and know that the engine in your car is the best it could be.
