This blog will introduce the Japanese national engine RB26 which was equipped on sky-line Nissan. Last century 90's it had won all champions in A group and G group of all Japan grand touring car championship (JGTC). Meanwhile it joined in journal of theoretical and computational chemistry (JTCC) 29 times, and won the champion 29 times. At that time in the Europe every touring car championship the GTR totally exceeded BMW M3 and Benz E90. The classic line six engine still is an amazing engine for many funs till today.  

At the beginning, the GTR design target was  Porsche 959 (450 horsepower), which means the GTR needed a more powerful engine. Under this condition, the RB26DBTT was produced . At that time, the main purpose of this engine is not only a economic target, but also contained many engineers dreams.The honors of GTR must contributed to this RB26DBTT engine. 

RB26 used the line six structure, which has great smoothness of operation and good linear output. And-then designed in double over head camshaft and each cylinder has four valves. The cylinder block uses inspissate steel which result in the weight does not have any advantage, but it provides more potential to increase the horsepower. It almost does not need any reinforce the cylinder block, easy to get 1300 horsepower. 

Of cause the function above do not enough, is also has two high efficiency turbos and individual throttle, which can make sure enough fresh air   get into cylinder. The original engine is very easy to get 350 horsepower, if with some simple  refit 500 horsepower is not a dream.

This engine was serviced for three generations GTR. In Japan the government has the limitation of the vehicles' horsepower can not over 260 horsepower. This is a cruel limitation for GTR, so many super car players adjust their GTR by themselves and then they enjoy the process. That another reason why many people like this car which has a lot of  secrets waiting for you to discovery.

After two decades development, many other companies engines became more powerful, so the evolution for BR26DETT is necessary.

Even the BR26 already has more than 30 years history, it still has many possible for people who love it. Compared with many modern engine, it can not be called perfect. But it deeply attracted many players.
