Variable Inlet Cam Phasing – Nissan Skyline GT R33


This 1996 Skyline GT R33 is a two wheel drive forth generation Skyline. The front bumper and spoiler on this one appears to be an after market item.


Power was delivered by an RB25DET 250 hp twin turbo 2490cc / 151 cui straight 6 engine which featured variable inlet cam phasing ( NVCS ). Many of these vehicles have been sent to engine specialists for radical tuning, racing versions of these engines have shown over 500 hp.


It is thought that 217,133 R33 Skylines were produced from 1993 – 1998 and sold in Japan, Hong Kong, Australia and the UK, although officially imported many more are thought to have arrived in the UK as personal ‘grey’ imports.

Variable Turbine Geometry – Porsche 997 Turbo S

This is one of the last series 1 2008 model year Porsche 997’s distinguished by the LED indicators across the outer intakes and bug eye headlights lights from the older 996 with which it shares a four wheel drive power train.

With over 100,000 units sold the 997 is without doubt the most popular model Porsche have ever made even the TDM who is not a noted Porsche fan thinks a 997 will “make love to your fingertips and stir your soul.” Lets hope he washes his hands regularly.

The 997 Turbo was tested by TDM on an empty German Autobahn with an indicated 200 mph on the clock 2 mph faster than the top speed claimed by Porsche, Motor Trend tested the same model as capable of accelerating 0 – 60 mph (97 kph) in 3.2 seconds a full 0.5 secs ahead of the manufacturers claims.

The turbo S comes with a 525 hp 3,824 cc 233.4 cui flat six cylinder engine which introduced variable turbine geometry on the twin turbo’s.

Sadly this vehicle is already a late model a series 2 997 Turbo S was launched in 2010.

Hope you have enjoyed today’s variable turbine geometry edition of ‘Gettin’ a lil’ psycho on tyres’ and that you’ll join me again tomorrow for a look at a performance water cooled edition as we round out Porsche week.
