Technical Update

As it’s a long time since we published our British F2 engine rules I thought I’d republish them, as I’ve had a few enquiries from new teams joining us and existing teams changing engines etc. But don’t panic there are no new rules for next year [2022] this is just for information.

The engine from the head gasket including the head gasket is FREE – but must be still be under 600cc. Therefore the age [year] of the engine is decided by the year of the cylinder head.

The Cylinder Head is basically to “supersport rules”.

The following modifications are allowed:

1 - Grinding of the cylinder head on the gasket side.

2 - Modifications of the inlet & exhaust ports by taking off & or adding material. But welding is forbidden.

3 - Original homologated valve guides may be cut or modified, but only on the intake or exhaust port side.

4 - Polishing of the combustion chamber.

5 - Original valve seats must be used, but modifications are allowed to the shape.

6 - Compression ratio is free.

7 - The combustion chamber may be modified.

8 - Valves must remain as homologated by the original manufacturer.

9 - Valve springs, Valve spring retainers & cotters may be altered or replaced.


1 - The method of drive must remain as homologated.

2 - The camshaft duration is free BUT the lift must remain as homologated.

3 - The cam sprockets or gears may be modified or replaced to allow the degeeing of the camshafts.

Fuel Injection System (i.e. Throttle bodies)

Older throttle bodies can be used on a newer head But NOT visa versa. In other words for example Suzuki K7 throttle bodies are ok on an L head but NOT L throttle bodies on a K7 head.

The ignition system ECU is free.
