THIS IS WHAT THE RPO DECODER SAYS G92 : AXLE REAR RATIO, PERFORMANCE, I know the g92 option also came with dual cats, but what i was really wondering is what rear end gear ratio do i have ?? did the g92 come with any thing else ???

 

on the top of this page, click the search button and type in G92. There have been many discussions lately that will describe what the G92 package consisted of over the different years. It will be time well spent as you will find more information than you probably wanted. I'm not being a jerk, but different years included different things and there has been some discrepancy as to what was all included with G92.

 

You should have 3.23 gears.

 

My 89 Formula w/350-also G92 car--had 3.27's in it.

 

3.23 if it's a 10 bolt and 3.27 if it's a 9 bolt.

 

The auto G92s had 3:23s and the 5spds had 3:42s. 9 bolts were different like 406 said.

 

forgot to mention--had a 9 bolt.

 

9bolt 5spd 3.45

9bolt auto 3.27

10bolt 5spd 3.42

10bolt auto 3.23

Look for the codes starting with G before your G92 and you should find the axle code such as GT4=3.73 and so on, you should be able to decode on this site when you find it.

 

yeah my 88 formula had a 9 bw with the 3.27's posi, disk
and my 91 has 10 bolt with 3.23's posi, disk
