As we proceed on our journey to provide you access to some of the best motorsport classic cars out there, we’re thrilled to be discussing a fine piece of machinery known as the MGB Turbo Charged Roadster Special. This is one of the most enhanced roadsters that has ever hit the market and was meant to be direct competition to the Triumph TR series.
The origin of the GB dates all the way back to 1947 actually and was eventually produced in 1962 by the British Motor Company. It had one of the longest runs, between 1962 and 1980 and was one of the first vehicles to be made in a unitary structure, or really one piece, which was a better option for safety reasons. The MGB series itself wound up being popular because of its lightweight design, keeping costs low and the speed up.
Safety was a big concern in these roadsters, and MGB helped to implement crumple zones, helping to safeguard the drivers and their passengers during an accidental impact. Keep in mind it may not have as many modern safety features in cars these days, but in the 60s and 70s era of roadsters, it was definitely a mass improvement.
This also came about with the 1975 model that would also integrate some of the earliest power breaks into the car as a standard safety measure. Compared to non-servo assisted breaks that required drivers to exert extensive amounts of pressure on the breaks themselves and not always being able to slow down the car.
The original engine and manufacturing easily had the MGB series get up to 60 mph in just a little over 11 seconds. Unfortunately, it was such a powerful engine that the 1975 model in the United States actually had to be made a bit weaker due to the emissions and overall power of the engine. Unfortunately, US legislation modified construction for some of the cars that would add a rubber bumper in 1974, eliminating the chrome accents that made this one of the more stylish options.
Another unique cost-saving measure to occur with the 1975 model specifically was the elimination of the anti-roll bar which was part of the suspension for other models and used to support fast turns. That didn’t stop these roadsters, and eventually, in later models, the anti-roll bar would make its way back into manufacturing.
With that said, the look of the MGB roadsters has that premium classic blend of driving the car through the countryside for the long weekend or even when riding through a bustling city, showing off the power of the engine. It’s still such a popular car when it comes to collector circles that there are plenty of original spare parts available.
Yet when it comes to modifications, the MGB Roadster series is quite adept at accepting non-standard parts, as seen by our 1975 MGB Turbo Charged Roadster Special. Whereas the original torque was around maxed at around 140 NM in 1975 at approximately 2,500 RPM, this turbocharged edition has a massive 333 NM of torque. So not only will you have the ability to feel it when driving, but you’ll also be able to hear it.
While it still holds a 2 litre K series MG engine, it’s been turbocharged with a Garrett turbocharger and has added ventilated disc brakes with Hoyle coil-over suspension units, making this more of a sports car than a roadster. It will drive as you want it to, and you’ll appreciate the restored red leather interior that helps to bring this car back to its appropriate era.
