Need help finding previous owner

A few years ago my friends bought an st185 gt4. He bought it from a guy from Western Australia, who used it as a street registered rally car. This car is highly modified and beyond what the local mechanics know, now it's broken. (Timing belt tensioner keeps breaking)

It's distinuguishing features include:
Apple macintosh logo instead of a rear badge
wide bodied (about an inch wider (on each side) then any celica in melbourne)
mangelated front bar to provide flow to the cooler
marone in color
huge fount mounted cooler
wired (magna v6) throttle body
link computer
cardboard mounted gauges

Anyway if anyone knows the previous owner it would be greatly apreciated if you could ask him to contact me on 04 123 00 629 or (Jimmy)
