Okay so I found a website that is exactly what I was looking for. Under new laws of August 2014 in NSW
This just saved me buying a n/a s15 when I can buy a turbo s15 Spec R. Even the Spec R 200SX is legal. I'm guessing that's the best P plater car.
Legal ; S15 200SX Spec R (Turbo), s15 200sx Spec S (Turbo), S S15 Autech (N/a), R33 GTS, Supra SZ
Banned; S2000, R33 GTST, WRX, Supra RZ
If anyone want to add to this list go ahead!
