I have it on good authority that there is a 1200 coupe in WA with a SR20DET that recently went through the pits. the suspension shop that helped me get springs for my ute looked over it before it went through the pits. The car is a white coupe, originally from SA...... possibly brought over here cos it couldn't be registered there. The guy that owns it (I dont know him) works for one of the more respected racing workshops in WA.

Our local authorities are knobjockeys- they will tell you 'no that's not possible' and then pass a car with less legal mods than what you were proposing. A mate of mine's old man recently had a mustang passed with a highly illegal exhaust- his mechanic knew the mechanic at the pits. all about who you know, bugger all to do with following the rules.
