Nissan Skyline GTR

Engine
Similar to earlier versions, the RB26DETT drives the GT-R forward with an official 280hp at 6,800rpm (restricted by the Japanese regulations). But as the UK GT-R Register found out, 328 hp at 6,400rpm seem to be the real output. Modified camshafts for improved valve timing and a new stainless steel exhaust system with reduced back pressure make the engine more flexible thanks to a better torque curve and higher peak-output of 289 lb-ft (397 Nm) at 4,400rpm. These changes have also make this RB26DETT smoother and quieter in comparison to earlier versions.
Additionally, turbo spool-up time is enhanced by the new smaller twin ceramic turbochargers which feature variable boost timing, work with a maximum pressure of 0.4bar and use twin ball-bearings to minimize friction. Even though, as known from most turbo engines, there is quite some lag until the blowers really start going about their job at about 3,500rpm. But since the redline is still at an impressive 8,000rpm, there remain plenty of revs to work with.
