Supercharger Installations




We have been supplying these kits for over 20 years now and eventually it had to happen.

Our stock of manifolds has run out. The supercharger model we used has been superseded.

With the current situation of manufacturing in this country and so many good, reliable contacts either retiring or moving operations overseas it may prove difficult and troublesome to undertake the manufacture of a revised MG kit.

We will still endeavour to look after existing MG customers providing supercharger spares and rebuilds.
