Volkswagen – Audi – Skoda 1.9 Tdi
This is a first for us (but we doubt it will be the last). We recognised that there is very little out there in terms of a gas flowed cylinder head for a diesel car. There is big demand for electronic tuning of Turbo Diesel engines (As we know – We supply Unichip and Superchip electronic tuning solutions). So the question is – Is it possible to deliver substantial power increases by gas flowing a Turbo Diesel head.
The VW 1.9 Tdi engine is found in a great number of Volkswagen, Audi and Skoda models. This head is suitable for 1998 to 2004 engines. It gives great performance and economy. When we completed work on the head we found a further 10% flow on inlet and exhaust. We went further and actually built an ultimate Turbo Diesel engine and tested it on our dyno. The result was 350BHP. Thats not a misprint !! THREE HUNDRED AND FIFTY HORSEPOWER from a diesel.
Remember, the head you purchase will deliver the same flow as our final prototype. We publish our flow figures and stand by them. All heads perform as we say they will and are balanced across the cylinders in the head.
Call us for more details of modifications required to massively increase the power of you VW based Tdi engine.
Cost for this head is £900.00 + 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.
Note : flow diagrams show flow against specific valve openings at 0.050 inch valve openings at 25″ 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.

Custom made Camshafts
With all of our gas flowed heads we also provide a custom made camshaft service. These camshafts are designed to optimise the flow characteristics of our heads. They can also be specifically designed to deliver the power characteristcs you require for your specific application.Your existing camshaft will work with our heads, however, if you want to get the most from one of these heads or you have a particular power characteristc you are looking for, we recommend that you consider our custom camshafts.
Price £500 + vat

We are happy to discuss and advise on any aspect of modifying your engine with one of our heads to achieve the results we predict above. We can also supply the best quality gaskets, camshaft, valves, valve springs and head bolts to go with your new cylinder head. We also specialise in electronic engine management, carb and fuel injection , turbo and supercharger systems. We build race engines too. Built and tested on our own 1000bhp Engine Dyno. We can also fit your head to your engine if required and test your vehicle on our rolling road.
