Nissan Skyline Z-tune

In 1995 the new model Nissan Skyline R33 GTR was born with big shoes to fill because the previous model R32 GTR was a huge success. The first thing to notice about the new GTR is shape it looks much more modern with more of a muscle car type stance rather than the race car look. Itís bigger in all dimensions and looks it with its rounded styling instead of the R32ís hard edges. An aggressive front end and pumped guards still remain but an adjustable rear wing has been added to improve down-force.

The interior has improved from the previous model and is much more spacious a big hit for taller drivers. Extra gauges have been added and include oil-temperature and torque distribution. Driver and passenger side air bags have also been added to improve safety.

The superb RB26DETT engine remains and so does the 206kw claimed power figure however torque has improved from 375nm at 4,400 revs. One can only assume that the overall power figure was improved due to the increased boost pressure, improved intercooler, and the extra torque produced. Due to the extra 100kg's the R33ís straight line speed was decreased slightly 0-100km in reached in 5 seconds and the 400m sprint is completed in 13.1 seconds. Track times however where improved due to improvements to suspension, anchor points have been stiffened and travel lengthened. The ATTESSA four wheel drive and HICAS (now called Super HICAS) where also improved which also helps the lap times drop and aidís overall grip with its larger 17í wheels and tyreís.

Driving the R33 GTR has become more refined and comfortable. The softer suspension and the extra weight make it feel less like a race car than the R32. Steering does not feel as direct either but depending on what you are looking for this is either an advantage or disadvantage.

Overall the Nissan Skyline GTR has improved, its circuit times are quicker, and it is more comfortable than the old model. This is a hard feet to achieve and I think Nissan wanted this from the GTR so it would appeal to a bigger audience. But as mentioned before it has lost some of its race car like feel which in my opinion lets it down just a little. If you want a hardcore race car go the R32. If you would like a little more luxury the Nissan Skyline R33 GTR is the car for you.
