More power = more breakages?

Having spec'd the head to get greater flow, larger combustion chamber and a more aggressive cam….i can see some power related stresses taking their toll on the factory diff!

Couple the head work with bigger pistons (Calver +60thou flat tops) that will be going in to the rebored cylinders, taking the engine from 998cc to 1046cc….we'll be seeing some grins if we make it reliable!

So, out with the old and in with a shiny new "4 pin diff" from MiniSpares, as recommended by Swiftune and Guess-Works! Standard practice when updating the power.
