The Regal Grand National Turbo is a car that has gone through a massive transformation, as its original design was designed at the tail end of the 1980s and was later improved upon. While in 1985 it would basically be a mere carry-over year from the few upgrades outlined above, 1986 was a complete upgrade for the turbocharged turbo Regal Grand National. Physically, the turbo-finned, black-painted, silver-rimmed chrome-15-inch Mag-type wheelbase wheels of the 1984-1985-Grand Nationals were replaced with a set of black, stainless steel, Mag-type aluminum wheels, which looked remarkably similar to the Riviera T-Class wheels (also with a similar theme).
There are numerous modifications to take place, and the most obvious changes would be the addition of the turbo system to the car, which in turn brought about a massive weight increase. This is why there is a noticeable increase in the curb weight when the turbo is fitted to the car. Other changes include the addition of body kits, bumpers, and air horns, along with the addition of front and rear spoilers. All of these changes were done to make the car look as much like a Ferrari or Lamborghini as possible while making it look like the Grand National. As such, these modifications are all completely legal, as the car is a modified Lamborghini and therefore does not fall under the category of a street-legal.
When the turbo was first added, the turbocharger was simply attached behind the exhaust pipe on the car and the exhaust system was then put in line with the rear wheel. However, after a few weeks, the engine was tuned for better efficiency, and the turbocharger was simply bolted onto the exhaust pipe and the muffler was fitted to the back of the vehicle. In fact, when putting the turbo in the car, there is a lot more room for the turbo to be bolted into place, so it is actually easier to get an exhaust system fitted without any further modifications being made.
Since this change, the turbo has taken on a whole new identity of its own. Many cars have a standard body kit, and it is common for a Grand National to sport a very low profile hood and side skirts. However, since the turbo has been added to the car, the hood and side skirt have been moved forward to give the turbo the chance to be bolted to the roof and create a completely different look.
In fact, the original Grand National has a very unique feature, which is the large hood and side skirts which are found on both the ’87 and ’88 models. Although these parts are relatively small, they provide a great deal of additional lift to the hood, and they add a unique style to the car. Because of this, the hood and side skirt has been removed in order to allow the turbocharger to be bolted directly to the hood. There is also a slight increase in the height of the car, and its overall width and height when the hood is lifted as well.
Although the modifications made to the car are extremely small, the modifications can be likened to those of a sports car, and as such, there are some areas where the car has actually been modified. The turbo system now features a high-flow exhaust system, which is able to create a much louder exhaust sound compared to the original. However, there are many other areas where the original model can’t quite compare with the new version, as the exhaust system and turbocharger are completely different animals altogether.
For instance, the exhaust system which is used by the turbo system has a much bigger diameter than that used by the stock exhaust system, meaning that the volume of air used to drive the turbo is much greater. The same is true for the turbocharger, which is mounted a little higher. This new system also has a much larger intake manifold, which has been designed to fit the new turbo, as opposed to the older system which is built to fit the stock turbocharger and header. Finally, the new exhaust system uses a lot of extra turbulence, and a very large exhaust tip, allowing the exhaust to be sprayed directly over the top of the car.
Of course, all of this has been done with the intention of helping to make the new Regal GNX turbocharger the best turbo that money can buy, and with an eye towards reducing emissions. the carbon monotony that often comes from using the same exhaust system that has been used for many years.
