I spent ages here in Adelaide ringing around and talking to other guys with turbo mxs in adelaide about getting them legalised.. SA is a very hard nut to crack.. even after speaking to engineers, the whole process is bullsh*te here (even ask RandyMx5 on these forums) possibly costing $1000's and 1000s
I bought the AVO kit with at least the hope of getting mine road legal here in SA, even such that I ve even upgraded the diff and brakes etc etc.. but it costs so much here .. I havent been bothered yet..
Ive had mine on for almost a year and half now with no problems, and randys had his for like 9 years.. Just have to be sensible in how , when and where you drive it, and not have it looking to outlandish... the mx isnt your average cop magnet like the silvias etc yet..
That being said you could have a chat to MRE-Miatasport in thebarton thats who i got my AVO kit through and did my tuning for me see if they've got any updated info.
Keep us informed on how you go!
