gsl-se w/ non-se transmission
i have a gsl-se and i'm pretty sure the transmission is non-se, since the speedometer reads faster than the car is really going, which tells me the gearing has been shortened.
it has a 140mph speedometer. did all S3 cars have a 140mph speedometer, or was the non-SE cluster equipped with a 130mph speedo? i ask because i wouldn't mind using a 130mph speedo in order to have an accurate speedometer.
or am i way off here?

That's about normal. You can expect the speedo to read 5-10% too high. The thing to check by is the odometer - that should be rather accurate.

Wouldn't matter anyway, all of the speedos use the same speedo cable revs per mile (I think it's 1000rpm at 100km/h?).

What may have happened is that your tranny has been replaced on your SE with one that came off of a non-SE car. Remember that the SE's had 4.09 rear gears, and the tranny speedo gearing was modified to accommodate for this change.
This is one way that Mazda helped the SE's to do better on the 0-60 times to compete with other cars.
If you're trying to get it to read correctly, you may want to research finding the right replacement SE tranny with the speedo gearing already installed. HTH,

The trannies are the same, other than 5th gear. Checking the speedo driven gear is easy, just remove the 10mm(?) headed bolt holding the speedo gear housing to the trans, quickly pull it out and stuff a rag in there to keep too much tranny oil from spilling out, and count the teeth.
edit: Or you could just check the color... 17 tooth is green, 18 tooth is purple. (19, 22, and 23 are red, 20 is black, 21 is white, according to Randy Stocker's site)
