MAZDA RX7 ‘EX WORKS’ RX7 GpB CHASSIS NUMBER *MRT019*
We proudly present this UNUSED Group B Mazda RX7, having never been used it is absolutely immaculate. It is believed to be the last built by MRT in 1984, the car has been stored for all these years and not been touched, the original MRT graphics pack has not even been fitted. Finding a Group B Rally car in good order is rare but finding a brand new one is unheard of. This really is an incredible opportunity to own a perfect example of rallying history. The car also comes with a spares package including wheels and other spare parts.
It has been in the same ownership since 2002.
'The engine in this vehicle has recently been removed for inspection and is now fully reassembled ready for re installation.'
The engine is a naturally aspirated Mazda peripheral ported 13B twin rotor with rear wheel drive chassis. It’s a simple yet very effective setup, weight distribution was improved by shifting the motor 4inches rearward from the production car and fitted was a dry sump system. At the rear there is a dry sump oil reservoir, the engine oil is cooled through a large core.
It all amounts to a reliable 300 horsepower at 8500rpm but don’t forget this is a group B car, this beast was designed to be revved much further, the gauges even read 12000rpm.
Exterior & Interior
The focus wasn’t all on the power output, MRT worked on the RX7’S body, adding light weight widened fibreglass fenders front and rear, a fibreglass front cowl and vented fibreglass bonnet.
Super lightweight fibreglass doors feature as well, as do Lexan windows all round bar the windscreen. The total curb weight is roughly 930/960 kilograms.
Moving inside the RX7’s cockpit is a typically busy 80’s interior, with the dash filled with lights and switches it remains 100% original, with MAZDA gauges keeping an eye on all the critical pressure and temperature readings throughout the car.
Impressive looking in its own right, it sounds and performs even better. In the company of some extremely modified BDA Escorts the RX7 might not be as competitive, but it’s definitely one of the spectator’s favourites.
