A4 here.......i have the stock 3:23's on my 94 and will soon have virtually every bolt on...i was wondering what 3:73's would do for me? im sure many of you have changed your stock 3:23's to 3:73...what was the outcome...thanks

 

i changed from 323's to 373's i couldnt feel much of a difference but i noticed a little. I definatly like the 373's though.

 

Let ya know in a couple weeks. I have a set of Strange 3.73's sitting waiting to be installed

 

i dropped about .25 of the et with the change

for me, i felt it woke the car up. i didn't lose much in city driving, just easier on the gas

 

Well, its finally time to get rid of these nasty ol 2.73s. I have an appointment friday to get them installed. Will be putting in strange 3.73 gears Im pretty excited! Except im going to have to drive around with my computer all f'ed up for at least a week. Gotta get another computer from pcm4less

Now back to my real question... How much of a gain in ET should I expect. And everyone that went from 2.73s to 3.73s show me how much you gained.... current best in sig

You'll probably pick up a couple tenths. Some people pick up nothing, though.

 

oops i meant to click new thread, not post reply

 

Most people I know personally( not net heros) havent gained anything in the 1/4, and most of us went from 2:73 to 3:73

If you have a convertor though, once the gears are in, youll gain quite a bit. If you dont have a convertor, GO GET ONE. I went from 14.3 to 13.4 once i put in a vig 2800.

 

how do you know what kind of gears you have??? sorry don't mean to hijack. just curious

 

Look in your glovebox or inside of the door (depending on what year you have) and look for the RPO codes:

GU3 = 2.73
GU4 = 3.08 (3.8 Automatic V6 cars)
GU5 = 3.23
GU6 = 3.42

 

I would focus on power mods, your 323's are fine

 

So there is a good chance I wont gain a damn thing going from 2.73s to 3.73s???????
