RE: 2003 9-3 ARC lag
 

AFAIK removing the boost limit can be done via a manual boost controller or reprogramming.


The leak does sound like a rear main seal.

RE: 2003 9-3 ARC lag
 

Probably not a good idea to do that though eh? Removing boost controller? Is that mechanical or electronic?

RE: 2003 9-3 ARC lag
 

The stock boost control is electronic. The MBC is a manual thing which isn't all that big of a deal, but the ECU looses the ability to cut boost in a dangerous situation or in limp mode.

Hmmmm, I think I am going to buy this one: http://smartperformance.net/product_...products_id=37

This will eliminate my lag issues.. Throw a nice intake on there along side and she should be set eh? what do you think?

Write a review once you get it. I'm curious if it really does what it says it does. BTW if you start hitting boost cut in every gear you most likely put it in backwards :D Don't ask how I know.

RE: 2003 9-3 ARC lag
 

I have had my 9-3 aero for about a month now. No problems so far. From what i've gathered the turbo is liquid cooled so you might check the feed line to the turbo. I noticed the lag or lack of power in my 1st gear also. It's all there in 2nd though. I was thinking about going to my local saab dealer and seeing if it would hurt anything to increase the boost 1-2 pounds, thats all, just to pull a little more out of it. Not sure if it would hurt anything though, so i'm still researching this. After all that I'm hearing about Saab's problems I'm also considering getting rid of mine and going to BMW, before issues start with mine. I've looked at the reviews and there is more negative on Saab then good. way more. It's a beautiful car, but I dont want to be stuck in it and not have anything to drive. Plus I cant find any companies that have even a descent selection of aftermarket parts. If anyone knows anyone looking for a 9-3 Aero, I might consider any reasonable offers.

I probably can't afford an 06 Aero, even though I'd love to have one.

Hi, I also have a 2003 9-3 Arc with 120000 miles. I am having a pretty serious problem with the transmission, because it wont shift into fifth gear at all. When I try to, it makes a high speed grinding type noise and pops back into neutral. Fifth gear wont even engage. I checked the linkage and it was fine, and changed the tranny oil to see if that helped. I am guessing that it might be the syncro gear for fifth, but not sure. Any replies would be great!
