Gear ratios of phase 1 5mt 4.11fd 2.5rs transmission

Post by ciper »

I have a "rare" transmission and I am curious about it's ratios. It is from a 98RS which had a phase 1 5mt and EJ25D. (The 99 got ej251 and phase 2 5mt). I'd like confirmation of its gear ratios. It's likely to be the same as the five speeds from the 96-98 GT or the 98 Forester (which also got the EJ25D).

Part number TY752v2daa and I don't necessarily believe what can be found on google search since it all seems to be copied from that SPDA list. SPDA says 3.545 2.111 1.448 1.088 0.780 which are the same ratio as the phase 2 2.5RS transmission...

If you look on the SPDA page it lists that part twice with the same spec, but this page http://www.gearhack.com/myink/ViewPage. ... on%20Chart says the reverse gear ratios are different.

See post 7 in this thread http://www.cobbforums.com/forums/showth ... ith-ratios

Secondly what would the ratios be for a 91SS 5mt? I don't have the part number handy but I wonder if its different since this car had the rear LSD?
edit: This page leads me to believe my 91ss has transmission part number ty752vj1aa http://legacycentral.org/library/transmission/intro.htm
Just found a post Legacy777 made in 2003 that says ty752vj1aa "Speedometer gear tooth number (Drive/Driven) 29/9"
