Hello everyone, i am brand new to the SAAB community. Recently I decided to trade my mustang and a guy with a saab wants to trade. I like the car and want to, but one thing errks me. The car is a 2003 SAAB 9-3, but has an 04 9-3 aero engine in it. The car makes 18 pounds of boost, but after 15 mis fires and studders In all gears. He keeps saying is has a turbo off of a new saab, which is why it makes more boost. I have looked of forums and don’t see evidence of turbo swaps. He took the car to firestone and they looked at it and said it was the ignition coils’ fault for the spuddering, but that still doesn’t answer my question as to what turbo is it? How is it making more boost? Does it need tuned?

I know Aero's can make around 18 psi of boost

You're in the wrong forum posting about the 9-3 in the 9-5 section but it doesn't sound odd or anything. Lot of people want to upgrade from the GT1752 to the more robust TD04's, not sure what's in the NG 9-3's though

If the car got swapped the better turbo it probably does need a tune to match it (again, at least in the 9-5's case)

P.S if you want mustang level power (300-400ish? hp) without internals work the B204 engine is what you want, found in the 1999 9-3's, and others models too but I'm not sure what ones (also IMO they're way nicer all around than the NG 9-3's)

I think the car has an Aero ECU though, so wouldn’t that be okay? And if it does have an aero ECU that doesn’t justify the excess boost. I just don’t know much about these cars and don’t want to get jipped thank you for reply!

Just because it has the Aero engine in it doesn't mean it'll have the ECU to go with it, I think an '04 aero engine will work with a '03 base ECU, but don't quote me on that. An 'Aero' engine is just the same engine with bigger brakes, sportier suspension and of course a tune

Either way you're looking at some time with someone who knows Saab's so they can answer your questions with certainty, which will cost $$, but if there's no CEL's it does sound like it could be a simple fix

Edit: You probably don't want the car though, considering that it's Aero-level power (or so it sounds?) without the matching suspension, brakes, clutch, etc. making it not exactly the most dangerous thing on the road, but not ideal either

My short answer is no, you don't buy the car.

Seller has made some changes (maybe) to the car. It doesn't run right. Who knows why. So they decide to sell it.

A chain like Firestone won't have the first clue to how to make a tinkered-with Saab B208 work properly, or even how to troubleshoot it.

You will either have to learn for yourself (and that includes getting a Tech II tool and laptop with all the proper software) or find a local Saab specialist to do the work--and even there, success is not guaranteed.

If that sounds not so good, my short answer stands....

Good advice Ed.

Moving this discussion to the 9-3 forum...

The best Saab for a newbie is an old-person Saab that has been maintained but not modified. Then you know you are starting with a baseline that works and doesn't have any hiding issues. Then if you are keen on modifying it, you know what the modifications are, and if they don't work out, you can go back to the properly-working baseline.

It might cost a bit more, and seem a bit less cool, but in the long run it will be cheaper and less hassle.

I don't know where the OP is located and what exactly they're looking for, but I would think that a working, stock, automatic-transmission convertible with a good top will be way cooler than the most radically tuned sedan that makes psssht-psshht sounds on every upshift. And old-people Saab convertibles come up for sale a lot.

Makes sense. I appreciate the honest feed back. I didn’t want to get into something overly expensive and hard to figure out. Thanks everyone
