I have been looking after this car for some time, upgrading and renewing brakes, suspension etc, and recently fitted a protective mesh on the front bumper to stop stones/debris damaging the radiator after the last race at Silverstone.

However, it was a little too late as unknown to both myself and the owner, a small hole was already present in the radiator. The consequence was that the coolant finally leaked out at Donnington and the car overheated. 

The head gasket on the engine was compromised and would require replacing. The engine had done some hard racing over the previous couple of years, so a decision was taken to upgrade the engine and rebuild it. The car is going to go up a class and develop a lot more power than previously. 

The story is of the engine build, the up grades and finally a video of the car in action.
