that would be a japanesium supra my friend, RHD, and it also has both voltmeter and boost gauge..... damn lucky japanese!
besides, he might have taken a different gauge out or something in place for a voltmeter, i dont know as i have never had an import mkiii or seen a stock import mkiii so my guess is its just how they did the ones in japan
P.S. we all know how people feel about rhd tuners over here, would the japanese thing a lhd tuner over there would be the shit???
