Nissan Skyline GT-R R34
The RB26DETT found in R32 and R33 GT-Rs. Notice how the valve cover is not metallic red or champagne metallic, R34s came with painted valve covers.
The GT-R of the 1990s included a 2.6 L straight six-cylinder twin-turbo engine producing 206 kW (276 hp). The turbo-chargers were of a hybrid steel/ceramic design allowing them to spool up faster due to the light nature of the ceramic exhaust wheel.
Power was delivered to all four wheels using an electronically-controlled all wheel drive system referred to by Nissan as the ATTESA-ETS system. The ATTESA-ETS system uses two G-Sensors mounted underneath the centre console, which feed lateral and longitudinal inputs to the ECU. The ECU would then control the feed of power by allowing a limited amount to be delivered to the front wheels via an electronic torque split converter. In 1995, the ATTESA-ETS Pro was introduced as an option for R33 GTR customers, and came as standard equipment in GTR V-spec models. It was later standard equipment in all GTR models for the R34 Skyline GTR. The ATTESA-ETS Pro added an Active Limited Slip Differential, which was controlled by the onboard ATTESA computer. This was only for the rear differential, as the front differential remained as a normal Limited Slip Differential. The ATTESA-ETS Pro was also advertised in brochures as adding an electroniclly controlled 4-channel ABS brake system. Although it is not related to the all wheel drive system, it uses much of the same sensors, and the same computer.
