S&J MY99-00 STI Power Upgrade Kits

The mighty STI arrived in Australia for the 1999 model release, which saw S&J immediately modifying and tuning STI's with all sorts of power upgrade parts and engine management systems.

In 2002 when S&J first had the opportunity to test the ECUTEK engine management systems, prayers were finally answered on the tuning front, at last something that offered incredible performance, drivability and engine safety using the Subaru factory "Knock Control System". These early STI 2 and 4 doors alike are still one of the most popular models. A real "Drivers" car even in standard trim. The main features over the 99-00 WRX are: Forged Pistons, Lower compression ratio, VF28 Turbo, stronger gearbox, 4.44 final drive and slightly sportier trim detail.
