Australian vs JDM models
Australia and New Zealand were the only countries to officially get the S15. While in Japan the S15 was known as the Silvia, in both New Zealand and Australia it was known as the 200sx. New Zealand got what was essentially the Japanese domestic version of the car with the following main differences:
External electric antenna rather than the back windscreen style JDM one. Probably because the JDM antenna performance was not high enough for NZ
Different bonnet and boot badging with 200sx instead of Silvia
Different floor mats with 200sx on them
NZ did not get all the grade options. There were only two versions sold in NZ. The Spec R with the option of auto or manual transmission and later the Spec R II with 17" ROH mags and a new Pioneer stereo. This model was essentailly a standard JDM Spec R
The Australian model was more substantially different. Perhaps the biggest difference was the power difference. While the JDM and NZ models got the full power 182kW engines Australia got a de-tuned engine which only produced 147kW. This was supposedly because of Australian conditions which meant engine damage could have been more likely if the JDM tune engine was used. The key difference between the NZ and Australian versions were:
Different ECU which reduces power to 147kW
No rear wiper
No pillar mount boost gauge
No climate air conditioning
Slightly different exhaust - 1" shorter than JDM
No passenger vanity mirror in sun visor
Electric folding side mirrors
Two models offered, Spec S and Spec R although unlike the JDM version the Australian Spec S is turbo!
Spec S is the base model and Spec R adds sunroof, side skirts (Aero) and rear spoiler
Also available for both models is the "GT" spec car. This has JDM rear spolier, leather trimmed seats and steering wheel, standard wheels in crome trim, drilled alloy pedals, crome trim for door handles and gear lever surround, GT badging from R34 skyline
260km/h speedo and no 180km/h speed cut
