Citroen 1.6 C2 GT 16V

The Citroen Savo VTS 16V is a popular in rally motorsport and with street tuners due to its excellent chassis and ability to tune its superb engine. Our head allows you to make the most from any modifications you have or plan to have. If you are in to racing these excellent cars, then you really ought to be looking at one of our cylinder heads…. They will make the difference between your engine and the rest of the field.

Our new Citroen head shows some excellent results. A 13% increase in inlet flow and a massive 22% increase in exhaust flow make for some very useful power increases. Our predicted and tested power output for this head is 224 BHP at 9900 RPM or 207 BHP at 7900 with appropriate modifications to fueling and exhaust.

This head is intended for race purposes or road car owners who simply want ultimate power from their cars. This head increases the engine’s full potential and allows you to take your tuning as far as you want with the absolute maximum flow. An excellent performance upgrade for this classic engine.

Remember, all our heads are fully balanced across the cylinders. The CFM ratings we state here are exactly what you get and we have tested power predictions on our Dyno to within 1 BHP of our prediction. Buy with absolute confidence that you are buying a head with a huge amount of expert development work built in and will perform as we say they will.

Need a full race engine ? Contact us for details. We supply fully built race engines built in-house to the highest specification. We are happy to fit your new cylinder head or advise on fitting if required.

Cost for this head is £750.00 + vat on an exchange basis. (£350 exchange). A ‘taping’ service is also available for this head at an additional cost of £100 which will give the final hand finish to the ports and provide a further 1% flow. This price includes valves.

Note : flow diagrams show flow against specific valve openings at 0.050 inch valve openings at 10″ pressure. Therefore actual flow volume increase is measured as the area under the graph (indicated in yellow for inlet and blue for exhaust). Standard valve sizes are used on our heads unless specified as a big valve version. Tests shown here are carried out on a flow bench on a bare head without filters. Therefore the difference between a standard engine with standard inlet ducting and filters will be larger than shown here.
