Skyline GT-R R-tune (R34) '99

In May 1998, the EN34,HR34,ER34 and BNR34 addressed many of the concerns over the change from the R32 to the R33, with more emphasis on sportiness, and marked the introduction of the more fuel-efficient and environmentally-friendly RB25DET NEO engine. The RB20E engine was discontinued in the R34 base model (GT), and the RB20DE, after last being used in the R32 Skyline, was reintroduced in updated NEO guise. The R34 GT powered by the RB20DE NEO, coupled with a 5-speed gearbox, became the most fuel-efficient straight-6 Skyline to date (of any shape). The 5-speed automatic transmission available on some models in the previous two shapes were discontinued. In its place, Nissan produced a 4-speed Tiptronic transmission for all of the automatic versions (Except the base 2.0L, which has a standard 5 speed gearbox). This model of the Skyline was used in many street racing movies, most notably Fast and Furious.

The GT-R reappeared in 1999, with a revised chassis and other updates. The R34 turbos received a ball bearing core. The R34 N1 turbos had a metal exhaust wheel, and ball bearing center section. A 6-speed Getrag gearbox was used. The turbo outlet pipes were changed from cast to formed metal outlets. The intercooler had a temperature probe in the V-spec models.
