Nissan Skyline

The Nissan Skyline GT-R is an iconic Japanese sports coupé in the Nissan Skyline range. The Skyline name originated with the Prince automobile company which developed and sold the Skyline line of sedans before merging with Nissan-Datsun. The GT-R abbreviation stands for Gran Turismo Racer. The Japanese chose to use English as their first language when naming the car, as most cars made in Japan at that time used American abbreviation to further enhance sales. The earliest predecessor of the GT-R, the S54 2000 GT-B, came second in its first race in 1964 to the purpose-built Porsche 904 GTS race car. The next development of the GT-R, the 4-door PGC10 2000 GT-R , later to be superseded by the 2-door KPGC10 version, scored 33 victories in the one and a half years it raced and by the time it attempted its 50th consecutive win, its run was ended by a Mazda Savanna RX-3. The car took 1000 victories by the time it was discontinued in 1972. The last of the original GT-Rs, the KPGC110 2000GT-R, used an unchanged S20 160 hp (120 kW) inline-6 engine from the earlier 2000 GT-R and only sold 197 units due to the worldwide energy crisis. This model was the only GT-R to never participate in a race despite only having one built which now resides in Nissan's former factory turned storage unit for historical cars in Zuma.

The Skyline model became popular largely because it remained rear wheel drive, while most other manufacturers' models were front wheel drive (which had certain complexities inherent in achieving high performance in power or handling when compared to a rear-wheel drive car).




The Nissan Skyline R range houses the RB engine. Generally, R32s have RB20's and R33's and R34's have RB25s. Some later model R32s came with a non turbo RB25.




The Nissan Skyline GTR is one of the most loved performance cars to come out of japan. When the R32 GTR came out in 1989 it was considered to be way ahead of it time with the powerfull RB26DETT.

Turbo Charger vs Super Charger



Turbocharger


Turbochargers are a type of forced induction system. They compress the air flowing into the engine. The advantage of compressing the air is that it lets the engine squeeze more air into a cylinder, and more air means that more fuel can be added. Therefore, you get more power from each explosion in each cylinder. A turbocharged engine produces more power overall than the same engine without the charging. This can significantly improve the power-to-weight ratio for the engine. In order to achieve this boost, the turbocharger uses the exhaust flow from the engine to spin a turbine, which in turn spins an air pump. The turbine in the turbocharger spins at speeds of up to 150,000 rotations per minute (rpm) -- that's about 30 times faster than most car engines can go. And since it is hooked up to the exhaust, the temperatures in the turbine are also very high. Turbochargers are powered by the mass-flow of exhaust gases driving a turbine.


Supercharger

Another way to add power is to make a normal-sized engine more efficient. You can accomplish this by forcing more air into the combustion chamber. More air means more fuel can be added, and more fuel means a bigger explosion and greater horsepower. Adding a supercharger is a great way to achieve forced air induction. In this article, we'll explain what superchargers are, how they work and how they compare to turbochargers. A supercharger is any device that pressurizes the air intake to above atmospheric pressure. Both superchargers and turbochargers do this. In fact, the term "turbocharger" is a shortened version of "turbo-supercharger," its official name. Superchargers are powered mechanically by belt- or chain-drive from the engine's crankshaft.
