Turbocharger Hiflows 12A 13B Series IV & V

For some of you folks who are considering turbo charging your 13B, I thought you might be interested in the modification offered for the stock turbo (Hitachi HT18S). The price is $690 Aussie dollars (or approx $345 US + shipping). You can hardly get a rebuild for that price. Looks like the mods would be beneficial for aircraft application - more airflow and less back pressure.
