CNC engineered gas flowed cylinder heads

Toyota MR2 and MR2 Turbo






We predict this head can deliver 269BHP with suitable modifications to Fueling, Ignition and Exhaust. This makes this head a seriously competitive proposition for racing or modified street cars.


We can, of course advise on how best to make the most from this head whether you wish to fit yourself or commission us to fit or even build a full race engine. We guarantee that the head you buy will have the same flow as our fully developed prototype through our use of CNC technology. All cylinder ports across the head have identical flow. For the price, we don’t think there is a tuning option out there which can match the BHP potential of this head for a MR2. You will require work on fueling and exhaust to reap the full benefit but making these changes without looking at a gas flowed cylinder head will always limit the potential of the engine. As such, this head is money well spent.

Call us for further details.

Cost for this head is £950.00 + 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 CamshaftsWith 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.
