RB-26 | SWEATSHIRT

The first 2.6 L RB26DETT was rated by Nissan at around 276 HP (206 kW) @ 6800 rpm and 260 lb·ft (353 Nm) @ 4400 rpm. By the end of production, power levels had gone up to around 276 HP (206 kW) @ 6800 rpm and 289 lb·ft (392 Nm) @ 4400 rpm, not only because of developments and modifications to the engine, but also because of the "Gentlemen's Agreement" made between Japanese automakers to limit the "advertised" horsepower of any vehicle to 280 PS (276 HP). The RB26 is widely known and became quite popular for its strength and power potential, making it a modification friendly platform for tuners and aftermarket modifications in general. It is common for modified engines to achieve outputs of 500 hp+. Some of the most extreme and extensive modifications done to the RB26 have resulted in figures of 1000 hp+, even up to 1,638 hp.
