2003 Saab 9-3 Linear?

There are plenty of ways in which to make it go faster, but it isn't the cheapest car to do this to. There are various tuners out there who will reprogram your ECU, and this will push the power up, but beyond that, some additional parts are required. Maptun is about the most thorough, comprehensive tuner, and you might want to take a look at the following tuning guide to see what is required for each power output on a '03 linear.

There are others out there, but they happen to show software and hardware, so you get a comprehensive look at some possibilities. Other ECU tunes are available from Nordic and BSR, while exhaust and the such are available all over.

They are pretty reliable as long as you 1. get it inspected at a certified SAAB MECHANIC, have them check for sludge 2. keep your OIL CHANGED, with SYNTHETIC oil...Trust me this makes a huge difference. The main issues with the '03 is that it still can have an issue with engine sludge if the oil isnt changed regularly. A certified Saab mechanic can check for sludge by dropping the pan. If it runs and drives good, its probably ok but you may have to have the oil pan and everything cleaned out periodically to keep sludge out, but dont let that deter you, they are great cars. Not to mention half the cars now days have sludge issues. Aside from that, there will more than likely be little quirks that are not serious and not expensive. and make sure you keep up with general maintenance. I have loved and driven Saabs all my life, my 1999 has almost 300,000 miles and I can count on 1 had the problems Ive had, Its been very reliable.

The most cheapest way is to get a K & N Air Filter, it will give you a bit more acceleration by adding some more horse power. Other then that go to maptun dot com.

There is no real way to make it go faster cheaply. You could upgrade the turbo to a high pressure one found on the aero's or just go after market altogether. I have also listened to 9-3's with borla exhausts and they do sound nice. However nothing you do to it will be cheap.

Cheap, performance and SAAB do not go together. There is not really much performance parts support for SAAB's.
