Vitesse Ltd produce the MGB “which the factory should have made but didn't”

The Product

Vitesse Global Ltd have developed a kit to convert post 1968 MGB’s into the car which Abingdon should have made to succeed the MGB and Austin Healey 3000, but didn’t.

It has a 4 litre V8 engine with 5 speed gearbox and includes all the necessary ancillary components, to deliver a perfectly matched package of silky smooth gearbox with the well proven torquey V8 engine giving a “No Brainer” turn-key well balanced drivers car, which sounds wonderful.

The fitted price of the kit costs £17,500 + VAT.  When added to the value of a donor MGB, the package adds up to making this the best and most reasonable new and useable classic on the market.

This package has been developed by Vitesse Sales Manager Alec Poole who with his colleague Roger Enever were Works MG drivers in the Sixties and were the most successful MG International race drivers of all time.  Roger’s Dad Syd Enever was Chief Engineer at MG Car Co and fathered the MGA & MGB.  Alec trained as a BMC engineering apprentice under Syd.

Are you using the Mazda MX-5 gearbox? I wouldn’t have thought it would be up to handling the torque of the Rover V8.

Phil Hallett - September 6, 2017

When I was a lad in the 50’s I dreamed of being a car designer, but never got past scribbles in exercise books. The name of my world beating car? The Vitesse! So, when added to my favourite car, a 1964 MGB roadster, in which I fantasised about installing a V8 engine, it seems you have the perfect package. All power to your elbow!
