The price I have on turbos is mainly based on condition of turbo(s). Rec retail on the AX's are 398,000Yen, so loosely convert that to $AU5,000. This is a loose figure not including shipping, gst/customs fees or even a discounted "sale" price. All of HKS bolt on replacement turbos are cheaper than the AX series, so one would hope that there is something exceptional about the Apexi's.
