During 1978 Ford Motor Company commissioned Boreham to build three special RS1800 Escorts designed to excel on Tarmac. The three cars were built to Monte Carlo specification and run full 2 litre BDG engines.  Brain hart built the engines using special cams and fitted with Kugelfischer Fuel Injection. The cars were used by Ford on the 1979 Monte Carlo Rally by Bjorn Waldergard and Hannu Mikola. Russell Brookes used the third car on the 1979 British Open Rally Championship.

One of our customers Malcolm Montgomery acquired one of these lightweight Monty Carlo Escorts and has now beautifully restored the car back to its former glory. Malcolm was a huge admirer of Bertie Fisher who had owned the Escort previously so when restoring the car it was painted in his colours and fitted with one of our 2 Litre BDG engines on 48 Weber carburettors which is how Bertie had run the car.

Grant Shand of RallyXtreme contacted us in 2013 to say he was thinking of building a lightweight Tarmac spec Escort and asked us about building a Kugelfischer Fuel injected 2 Litre BDG engine. Grant drove the newly built Escort on four events to test it before asking Marty McCormack if he would be interested in driving the car on Rally Boucles Chevrotines 2016. McCormack jumped at the opportunity setting the fastest times on every stage, winning the historic category by over two minutes. If the national rally had been combined McCormack would have finished 2nd overall!

In our opinion this combination of car and engine makes it the quickest, most flexible Rally Escort ever to be built.


Modern technology has moved on since 1979 when Brain Hart first built the original Monte spec Kugelfishcer engines. Our knowledge and experience gained over the past 40 years combined with the introduction of computers and CNC machines has allowed us to develop the BDG engine with a Kugelfischer system, concentring on drivability and flexibility. Many hours were spent on the dyno using throttle position to map the fuel cone profile, this now accurately delivers the correct fuelling at many loads and throttle positions, similar to an Electronic system.  The end result has given us a flexible engine that runs from 9000rpm to 2000rpm full throttle and drives like a manufacturers modern road car.
