i have just changed vic plate to sa plate 2 weeks ago for my R33. the car has big intercooler w/o mesh, exhoust, boost controller, momo steering wheel, S-afc, rsm, guages, air filter etc and has no problem as the guy only check my vin and engine number. The only thing his not happy about is my car height which was 315mm where legal hieght should be 365. I change the spring for $100 and pass through regency the second visit easily. It was check by an old man Dont ever get your car check by the young guy cause he likes to act smart.
