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. It’s bigger in
all dimensions and looks it with its rounded styling instead of the
R32’s 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 R33’s 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 aid’s overall grip with its
larger 17’ wheels and tyre’s.
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.
