what diff ratio does my imp have?

Featured Replies

I remember back when i had EA cars.. but now with the impreza, I cant just look at the sticker on the rear diff to tell what ratio I am running :-\

 

I am planning on going with the EA D/R swap.. but I need to know if I need to swap rear diffs too? does my impreza (1994 5spd L wagon EJ18) have the 3.9 or 4.11?

 

how can I look it up, some other way than rotating it and counting the revs...? :rolleyes:

on the rear-end,there's a label that has the ratio on it. at least on my 94 legacy there is.

 

lay on your belly an slide under the back-end there should be a label like this

thats what I mean, that tag, which all my previous EA cars had.. the imprezas no longer have that tag back there... there is no tag at all on it... it has what looks like mini "heatsink fins" on the backing plate.. so thus, no place to put a sticker...

The info I have says the 95 AWD has a 3.90 final drive ratio. I would "guess" the 94 is the same. However you may want to confirm that on NASIOC. There's bound to be people that know.
