s'ko Posted June 29, 2006 Share Posted June 29, 2006 Any thoughts here? I have a 5 spd imp that i has a damaged tranny. Let a buddy drive it and he wasn't use to the short throw shifter. Down shifter from 5th to 2th on the freeway. I have a GL-10 tranny and LSD diff in the garage. 1) What are benefits of going from the stock Imp gearing to the GL-10 gear? 2) Besides that adapter plate and wiring a cable clutch what else needs to be modded. Speedo cable or anything else? BW Quote Link to comment Share on other sites More sharing options...
Dr. RX Posted June 30, 2006 Share Posted June 30, 2006 The tranny ratio might be different then the Impreza rear diff. Tranny mount is different. But the big question is WHY?? Just because you have it? It will probably cost you more to make the GL-10 tranny fit into the Impreza then it would just to get another Impreza tranny. I hope you friend is paying for this, he isn't much of a friend if he isn't. Quote Link to comment Share on other sites More sharing options...
baccaruda Posted June 30, 2006 Share Posted June 30, 2006 i would recommend the same thing; find another impreza tranny, it's built for the larger engine in your car. You can modify the LSD to match your EJ transmission's gear ratio, there are directions in the USRM. good luck with your friend Quote Link to comment Share on other sites More sharing options...
NorthWet Posted June 30, 2006 Share Posted June 30, 2006 I have wondered this all day (Note to self: Get a life...): What makes you think that the tranny is blown? It is far more likely that overreving will blow up the engine before it bothers the tranny. Is there a hole in the tranny's case? Sorry for going OT, but these things nag at me.

s'ko Posted June 30, 2006 Author Share Posted June 30, 2006 yeah that's what I figured. Does anyone have a chart of gear ratios from the various EJ years? For some reason there seem to be a lot of Legacys going to the PAP and not imprezas. I have seen some 5spd awd Legs there so that my by inexpensive source for a tranny. I guess I need to replace my clutch anyways so I might as well do both at the same time. BW Quote Link to comment Share on other sites More sharing options...
subyrally Posted June 30, 2006 Share Posted June 30, 2006 the legacy bits should be a direct replacement for the impreza, just make sure the gearing matches, mainly the final drive. Quote Link to comment Share on other sites More sharing options...
ballitch Posted July 2, 2006 Share Posted July 2, 2006 besides the outback, forester, and wrx, all imprezas and legacys share the same final drive, 4.111, so you can mix and match trannys. only thing is the gear ratios might be different from generation to generation, but as long as you match the final drive with your tranny you will be fine. i would like to see a fwd 5 speed from an EA car in a impreza w/ a helical front diff. ~Josh~ Quote Link to comment Share on other sites More sharing options...

I have a rear diff from a Legacy with a 3.90 ratio. I know Imprezas that have a 4.444 ratio. It is really hard to generalize with Subarus, just as soon as you think you have all the info, something else crops up. Quote Link to comment Share on other sites More sharing options...
970subaru Posted July 3, 2006 Share Posted July 3, 2006 you can bet that most any BC/BF NA 5mt awd legacy will be 4.11. any turbo legacy will be 3.9. impreza will be hard to say. I have seen 4.11 and 3.9, and only heard of some 4.44's. Quote Link to comment Share on other sites More sharing options...

All AWD 92-94 MT normally aspirated Legacies have a 4.111 final drive rato. All AWD 92-94 AT normally aspirated Legacies have a 3.900 final drive ratio. All FWD 90-94 MT & AT Legacies have a 3.700 final drive ratio. The 91 turbo legacy was the only one to have a rear VLSD. Quote Link to comment Share on other sites More sharing options...
s'ko Posted July 5, 2006 Author Share Posted July 5, 2006 Thanks for all of the info. Does anyone know what the final drive of my 2000 OBS.

s'ko Posted July 6, 2006 Author Share Posted July 6, 2006 woohooo.. Source a L 5 spd tranny and rear diff for FREE. All I have to do is weld some stuff for a guy doing a RHD conversion on a L. He's dropping a EJ22T into a L. Quote Link to comment Share on other sites More sharing options...
abeattie220 Posted October 27, 2010 Share Posted October 27, 2010 im in the the middle if converting an impreza auto to an 87 DR 5spd fairly strait forward so far but its not a daily driver just a toy Quote Link to comment Share on other sites More sharing options...
Numbchux Posted October 28, 2010 Share Posted October 28, 2010 im in the the middle if converting an impreza auto to an 87 DR 5spd fairly strait forward so far but its not a daily driver just a toy please stop digging up 4+ year old threads! It's great knowing that you're using the search function....but the next step is watching the date on your search results. Quote Link to comment Share on other sites More sharing options...
