Chris’ rare Australian delivered 2-door Subaru Sti is a good example of improving what is already a great performance platform. The WRX now features a later model larger 2.5L boxer engine and 6-speed gearbox. Improved performance comes from a Garrett GT3071 turbo mounted in the factory location and an A’PEXi Power PC plug in computer making 250kW to all four wheels on pump unleaded petrol.
