Adam N.D.J. Posted July 28, 2005 Share Posted July 28, 2005 A 3.90 ratio RX transmission? We're talking the exact same RX tranny, with the exception that the final drive is 3.90 instead of 3.70 Just wondering if there is really a demand for it, if it's worth it to actually start sourcing transmissions and working on them.

TheSubaruJunkie Posted July 28, 2005 Share Posted July 28, 2005 i think the demand for RX trannys with EA81 splines would be higher. If you could couple the 2 you'd have pretty much a bolt in upgrade for any EA81 (minus the driveshaft). -Brian Quote Link to comment Share on other sites More sharing options...
Adam N.D.J. Posted July 28, 2005 Author Share Posted July 28, 2005 That too would not be a problem. Could actually work out a package deal. Quote Link to comment Share on other sites More sharing options...
JWX Posted July 28, 2005 Share Posted July 28, 2005 I'd be interested, depending upon the price. Quote Link to comment Share on other sites More sharing options...
NoahDL88 Posted July 28, 2005 Share Posted July 28, 2005 Why stop at 3.90, would it be possible to put in 4.11 and the real low range, 1.59? What exactly needs to be done to retain the AWD and get the 3.90 gearing? Quote Link to comment Share on other sites More sharing options...
baccaruda Posted July 28, 2005 Share Posted July 28, 2005 BeefARu has in his GL10 an RX tranny with: *4.11 gears *Forester 5th gear for highway driving (3000 RPM @ 70ish mph) *Legacy AWD differential instead of the RX locking center differential *vacuum solenoid hooked up to high/low shifter since the RX locker is gone just a suggestion Quote Link to comment Share on other sites More sharing options...
MorganM Posted July 28, 2005 Share Posted July 28, 2005 Having those 4.11 gears would make low range not feel so wussed out. Did they just come out of the Legacy gearbox ? Quote Link to comment Share on other sites More sharing options...
Sweet82 Posted July 28, 2005 Share Posted July 28, 2005 Having those 4.11 gears would make low range not feel so wussed out. Did they just come out of the Legacy gearbox ? If they do, a 4.11 should be the target gearing. (My forester is a 4.11) If a 4.11 is readily available why stop at 3.90? This would help our poor crawl ratio...

MSSLGECKO Posted July 28, 2005 Share Posted July 28, 2005 It sounds like a great plan to me. Any ballpark pricing for something like this? Only problem that I can see with this setup is that I'm broke. Quote Link to comment Share on other sites More sharing options...
carfreak85 Posted July 28, 2005 Share Posted July 28, 2005 I'm about to do this to my RX tranny for my wagon. While I'm in there, how do I swap to the lower-low range? Does anything need to be modded to do this? Quote Link to comment Share on other sites More sharing options...
Adam N.D.J. Posted July 28, 2005 Author Share Posted July 28, 2005 Right now I'm just looking at how much of a demand there is. I haven't had a Legacy tranny in my hands as of yet, so I don't know what it would take to put in 4.11 gears. I know that 3.90 isn't that hard to do. Also I'm still working on a source for conversion parts. I will only use new stuff, don't want to use junkyard stuff just to have it go bad, that wouldn't help reputation any. I'll take a look into the 4.11's in the next week or so, if I can get a Leg tranny. Looks like people do want this, so it's prolly worth the time to research it.

ShawnW Posted July 28, 2005 Share Posted July 28, 2005 Im in the process of doing a 3.90 one. Ill keep u in the loop if it works. Quote Link to comment Share on other sites More sharing options...
TheSubaruJunkie Posted July 29, 2005 Share Posted July 29, 2005 You can find 4.11 gears in most Impreza 2.5RS's from what I understand. A couple friends are running them in their Turbo Legacy's. I have a RX tranny I could bring up there Adam, maybe I can find some 4.11 parts from some locals here. But I say keep the RX's locking diff, but make it a mechanical activation instead of a switch. -Brian Quote Link to comment Share on other sites More sharing options...
subyrally Posted July 29, 2005 Share Posted July 29, 2005 i could dig the rx 5 spd with ea81 splines. i wouldnt mind 3.0 but then again, i never had any problems with 3.7 in my rx. yeah, id just be happy with a 5spd that i could bolt into a brat without too much effort.

subynut Posted July 29, 2005 Share Posted July 29, 2005 4.11 gears would be nice! That would put my speedo just about right with the 185/80r13s on me Suby. OOOH, more torque. Let's see how many CV's I break! On question, would the clutch type LSD that I have in there now fit in a 4.11 geared rear dif? It should, am I right? There are times where having AWD is nice: dry pavement, rainy days, things of the sort. But when I'm on the trails, I want the ability to lock the front and rears together. If you could put the 1.5 low range and 4.11 final drives in the full time lockable tranny, that might be somthing I'd try. I live in a world of rocks and soft sand, I need my torque.

subynut Posted July 29, 2005 Share Posted July 29, 2005 Just use the VLSD 4.11 rear end. From what I've read, the clutch type gives better torque distribution than VLSD. Maybe it's just in my imagination. Quote Link to comment Share on other sites More sharing options...
