fbh Posted February 22, 2006 Share Posted February 22, 2006 Hi folks, I'm planning on converting my EA82 to RWD only. Down here we don't get snow, so the pavement's dry all the time In any case, RWD (Right Wheel Drive) generally drives a helluvalot nicer than FWD (Wrong Wheel Drive). So the question I have is this: the tranny is a D/R 4wd 5-spd. Can I take out the front driveshafts and run it in 4WD permanently, thus making it RWD? will it be rugged enough to survive, say, if I were to stall the engine from high revs? I'll probably be modifying the 4WD selector lever also to make it so it can't be put back into FWD (otherwise I'll lose power ), and unplug/remove the 4WD dash indicator light, and just leave the low ratio light (I still want the D/R feature! ) what do you folks think?

idosubaru Posted February 22, 2006 Share Posted February 22, 2006 it'll work so long as the center diff stays locked. did you try a search? i know others have done it, but not sure if i heard that here or on another forum? would be here or xt6.net at least.

fbh Posted February 22, 2006 Author Share Posted February 22, 2006 forgot about the search, sorry :/ I don't think it actually has a center diff... Link to comment Share on other sites More sharing options...
MSSLGECKO Posted February 22, 2006 Share Posted February 22, 2006 I was running this setup in my '83 Brat w/ 4SPD D/R and it was AWESOME. RWD drives waay nicer. Anyhow, yes your tranny can take it just fine as long as you are very careful that you never shift into 2WD when movingm, or else! I constructed a plastic trim piece that stopped the lever from entering the 2WD selection. I was doing a lot of shifting between 4Hi and 4Lo and didn't want to take up shifting time by being careful not to select 2WD. You can get some sweet slides dropping into and out of Lo. Good luck, have fun, and wear your seatbelt! Link to comment Share on other sites More sharing options...
idosubaru Posted February 22, 2006 Share Posted February 22, 2006 forgot about the search, sorry :/I don't think it actually has a center diff... i thought they had a center diff, but i've been wrong before. the XT6's definitely have a center diff and i've seen mention of swapping in WRX LSD center diffs on EA82 manual trans so i would think there's a chance it does. can't imagine how else they'd make it work. and the center diff is what gets fried if you tow an AWD soob. if you have the PT4WD trans then maybe that's different, i'm not sure, but if it's FT4WD then i think it has to have a center diff.

Numbchux Posted February 22, 2006 Share Posted February 22, 2006 You're most definately not the first one to do this... there have been a few that have damaged the rear output while abusing it substantially... BUT, lo range RWD and front ebrake are a wonderful combination: Link to comment Share on other sites More sharing options...

That's why you can't use 4WD on the road Link to comment Share on other sites More sharing options...
Jack in Norfolk Posted February 22, 2006 Share Posted February 22, 2006 When I was too broke to replace both broken front axles I would cruise around in rwd. Even if you dont get snow, rain might be a concern. I seem to remember my 86 wagon being really light in the rear. It didn't take much to break the back wheels loose. I know this is fun at stoplights, but it could be a safety concern. Link to comment Share on other sites More sharing options...
simple monkey Posted February 22, 2006 Share Posted February 22, 2006 its about time this topic came up. as far as your drivetrain parts, if you are just using this as a daily driver, a lot of stuff is going to break. the first thing you will want to do is modify your subframe so the differential and other parts dont wiggle around and break. i'm not sure about your diff lasting too long, so i would suggest the diff out of a rwd car such as a nissan or a toyota (reliable and somewhat cheap). over on http://www.kungfutouge.com/ there is a guy who converted his outback wagon to rwd. he's using a nissan differerential. the only problem with that is you have to have custom made axels. hope that helps.

Johnnyboy Posted February 23, 2006 Share Posted February 23, 2006 LOL... It might not snow in Auckland, but it sure hasn't got dry pavement all the time, it rains 28 days a month! i know, I used to live there:D Are you planning on making a drift car?

fbh Posted February 23, 2006 Author Share Posted February 23, 2006 LOL, true, true - this is Auckland - don't like the weather? wait 30 minutes that's actually a now-famous quote by Augie Auer at the America's Cup races - on one of the race days there was no wind at all, and he's like "Oh, if you don't like the weather wait 10 minutes", and sure enough, 10 minutes later there was a pretty good breeze going Anywho - nope, not planning a drift car - just want to improve the handling a wee bit, it'll be a PITA to stop it from losing traction (already loses it quite easy just in FWD) but after driving my old man's RWD, I decided my next car's going to be a RWD as well Link to comment Share on other sites More sharing options...
idosubaru Posted February 23, 2006 Share Posted February 23, 2006 he's using a nissan differerential. the only problem with that is you have to have custom made axels. hope that helps.depending on diff custom axles shouldn't be necessary. some nissan and subaru differentials are interchangeable, just have to swap the stub axles for the bolt on nissan stubs. those are interchangeable on the diff side so the axle stays with the vehicles. nissan guys call our (EA series) 3.7 and 3.9 rear diffs R160 and R180, same differentials used in 80's nissans. only the stub axles differ and they are interchangeable. so really you have whatever you want with no axle change. if you want 3.7 or 3.9 get the subaru (or R160/R180 nissan designation of the same box) or the newer soob diffs of higher ratio if you wanted that for some reason. 4.11...4.44...

carfreak85 Posted February 23, 2006 Share Posted February 23, 2006 Once I get a pair of the rear stubs, I'll be doing the RWD conversion this spring. Link to comment Share on other sites More sharing options...
ballitch Posted February 23, 2006 Share Posted February 23, 2006 the R160 is the same rear diff used in the WRX and ALL legacys/imprezas, only difference is the gear ratios, so if you can have a modded WRX with 400hp with stock drivetrain handle it...i think the 80-90hp a N/A EA82 puts out with be okay.....now the tranny output gears on the other hand......will break. im going to try this in the summer when there is no chance ill need the 4WD for mud or snow. but i will have to be careful on the upshifts... ~Josh~ Link to comment Share on other sites More sharing options...
Numbchux Posted February 23, 2006 Share Posted February 23, 2006 the drivetrain is plenty strong!!! it handles alot of abuse offroad with 28" tires, and only fails if you have extreme CV angles Link to comment Share on other sites More sharing options...
fbh Posted February 23, 2006 Author Share Posted February 23, 2006 Sweet! I don't think it'll be doing any extreme angles, it's not lifted or anything Link to comment Share on other sites More sharing options...
Phizinza Posted February 23, 2006 Share Posted February 23, 2006 In any case, RWD (Right Wheel Drive) generally drives a helluvalot nicer than FWD (Wrong Wheel Drive). I disagree 100% on this. I have driven many cars and with the older jap cars it is definitely wrong. FWD is better for handling in these old jap cars. My brothers 88 Mazda 626 turbo handles and accerlerates much,much better then his friends 8? Skyline, and the Skyline has more power (ft-lb and hp)... This is what I have heard. RWD Brat drives almost the same as a it did in FWD, but RWD is worse on dirt roads. The whole RWD, front handbrake thing sounds like alot of fun. And don't worry about breaking anything, I've heard they keep together quite well. All that, RWD stuff, said - the best handling car I have driven is a mid engine RWD fiat x1/9. Such a pleasure to drive. Link to comment Share on other sites More sharing options...
fbh Posted February 23, 2006 Author Share Posted February 23, 2006 Ah yeah - I don't really mean nicer in terms of power etc, just that when you're accelerating/engine braking, torque isn't trying to steer the car, so the steering wheel permanently feels loose and you get better feedback from the road Link to comment Share on other sites More sharing options...
Phizinza Posted February 23, 2006 Share Posted February 23, 2006 I run 27's with no power steering. I have never had the car pulling more then comfortable while on road. I have driven some RWD cars, WITH power steering, that are worse then my subie. But if you like RWD and over steer, and hate under steer, I can see why you would like it. I guess you americans are used to RWD anyway. dual carbs and RWD... BURNOUTS!!! Link to comment Share on other sites More sharing options...

Heh heh heh, not to mention the weight distribution of said wagon... good burnout machine I'd reckon, light behind, RWD, front parking brake, dual carbs, low range...

85Sub4WD Posted February 23, 2006 Share Posted February 23, 2006 to be honest, I really don't see any advantage beyond the sport value of burnouts of RWD - the car has a decent weight distribution for FWD, and with good, careful throttle control, you can do a heck of a lot more on curves with a FWD car than a RWD car (you can use the drive to "pull" the car through turns) - I have driven both types, and by far prefer FWD if I have to choose between the two (AWD/4WD for slick conditions is best, AWD is best period for street) the only thing that is aggrivating with FWD is when they put the engine in sideways bottom line, don't do anything you can't reverse!! tranny output gears should be fine if it is D/R - I know S/R trannies have sheared the output gears on people, probably because the vacuum engage didn't go all the way or something, dunno - it's been a while since the person posted the problem good luck!!

Accelerate or turn. The tendancy to overwhelm the front tires is MUCH greater if they have to be relied on to both accelerate and steer. Yes... you can trail brake, yadda yadda yadda, but there is a reason that all race cars are RWD. If you can honestly tell me that you have never experienced throttle-on understeer in your Subaru at the limit, I will take back my post. Link to comment Share on other sites More sharing options...
DJtheGOD Posted February 23, 2006 Share Posted February 23, 2006 RWD is ok but why not drop in an AWD gearbox from the Vortex and have AWD instead Link to comment Share on other sites More sharing options...
