SAAB Tuning

Super-tuned Saab 9-3 Aero +600hp

A lot of work and money has been put into this car – money, work and of course huge enthusiasm. Owner of this super-tuned  Saab 9-3 Aero 2.0T -02  is a young Swede Joel Artursson.

The car has been in its possession for 5 years and this is his first car (He is only 23 years old) and it has gone from completely bone stock to the present setup. According to his plan, the power output of this build will be around 600+hp, and main goal is to achieve this power with lowest boost possible and with a revlimiter at 7500rpm.

The legendary Nordic 2.5GT valve cover

Future plans of this car is to start competing in the Swedish Time Attack series. Full roll cage with weight reduction. Full aerodynamic kit with big GT-wing, canard wings, diffuser, completely flat bottom of the car and carbonfiber splitter. But still maintain it as a “road legal” car and use quick release on everything.

Below, which probably many enthusiasts interested, we present a more extensive list of modifications that Joel is performed on the car, and what should be further.
