Nissan Skyline GT-R R33 – Introduced in 1995,

the GT-R R33 came with a 2.6-liter twin-turbocharged RB26DETT I6 engine. It also had a 6-speed manual transmission and featured an all-wheel drive system.

This model was known for its impressive performance capabilities.

The Nissan Skyline R33 series was very similar to its predecessor, the Nissan Skyline R32 series. The GT-R was continued, as was the optional all-wheel-drive layout of the Nissan Skyline  sedans and coupes. The car was still very sporty, although it had grown a little in size and weight and had thus become less agile.

The weight disadvantage was compensated in the engine department though, by the new normally aspirated RB25, a 2.5l inline-6 with 190hp for the GTS-4 and GTS25 versions, and the far more powerful RB25DET, a 2.5l inline-6 turbo with an output of 255hp, which worked in the GTS25t. 

Nissan kept the GT-R RB26DETT engine with an unchanged 280hp, but had a broader torque band which made the engine more flexible. Also standard were improved versions of ATTESA-ETS and Super-HICAS.

Here are the engine specification variations for the Nissan Skyline Model R33:

RB25DE – This engine is a 2.5-liter naturally aspirated inline-six, producing approximately 190 horsepower.

RB25DET – This engine is a 2.5-liter turbocharged inline-six, producing approximately 250 horsepower.

RB25DET NEO – This engine is an improved version of the RB25DET, featuring variable valve timing and producing approximately 280 horsepower.

RB26DETT – This engine is a 2.6-liter twin-turbocharged inline-six, famously known for its use in the Skyline GT-R models. It produces approximately 280 horsepower, but it’s worth noting that the actual power output may vary depending on the specific model and tuning.
