The Ultimate Street Car Package was designed with one intention…to be the ultimate daily driver and weekend racer. This ultimate package was created to satisfy the hunger for pure, unadulterated power, while still having the ability to drive like a “normal” vehicle and receive exceptional gas mileage. Whether you are driving around town or racing on the track it will have the power and poise to handle anything you can throw at it.
The Ultimate Street Car Package is our most popular package for loads of top-end power and turbo spool-up. It will out- spool most any other turbo kit on the market on the stock 2.5-liter displacement. It’s not only the best bang for the buck for all-out power, it also produces exceptional torque and horsepower while still retaining extraordinary gas mileage.
Customers looking for drag race setups, power for large open tracks, or for all-out top-end power, we would recommend using the GT35R (.82 A/R) turbo. Full boost of 20 PSI can be seen by 4300 RPM and 10 pounds of boost is seen well before 3900 RPM. Customers looking for canyon racing, tight and twisty tracks, or a wider range of power might prefer the GT30R (.63 A/R) turbo selection. Full boost of 20 PSI can be seen by 3900 RPM and 10 pounds of boost is seen well before 3500 RPM.

“The STi has proven its on track reliability at countless NASA events and is one of the fastest in the unlimited time trial class, even beating a Radical. The best part about the fully-spec’d interior is that there’s a baby seat in the back.” Jay Chen – Editor
