Thanks, I did a search, but couldnt come up with anything useful.

you should learn to use the search button. and if it dont work the first time u try, try harder.

Sorry, I think I copy/pasted something wrong...

Anyway, just search for "RWD conversion" in the Transmission forum.

15 year old boys should learn to use the search button. and if it dont work the first time u try, try harder.
Well, old man, I did in fact use it, I didn't think to use conversion, I simply used rwd. Let me know if you need help crossing the road. :rolleyes:

perhaps. perhaps ill ask when i need to cross hte road next time. id ask you to walk me hoem from teh bars, but u cant get in..

I have no desire to drink.

you shouldnt. you're 15. end of discussion.

I mean, I never will drink. My grandfather just died from it, and I don't think that's a direction I'd like to go. How old are you, anyway, since you seem to have an attitude toward me solely because of my age?

Can you change these cars to rwd safely and easily? Thanks.


Yes, You can safely (well, depending on how you drive) and easily (if you're good with a wrench) convert your Manual transmission subaru to rear wheel drive. Here's some good information about how to weld the center diff. http://www.clubwrx.net/forums/showthread.php?s=&threadid=27532

Here's what a welded center diff looks like

I just got done doing this same conversion to my car. I wanted to know what a RWD Subie felt like, and it's definately different. If I step on the gas at all going around a corner, the rear end comes out... I have no traction through 1st and 2nd gear... I'm going back to AWD in a week or so.

Here's my Legacy on the lift while I was rebuilding the transmission... Broken 2nd gear...

Now with a Rear 3.7 Clutch Type LSD from a 1986 RX:
http://img223.imageshack.us/img223/9234/dsc02589medium8tf.jpg

sick. so u figured out how to make the clutch LSD work. roxor.

how'd u end up doing it?

Well, My transmission was built to have a 4.11 Final Drive. I was using the 1991 Turbo Legacy transfer case, but I picked up a spare WRX transmission, so I used the transfer case off of the WRX. The transfer gears in the wrx are 1.1:1 (WRX's use a 3.54 rear diff, and with the center gears being 1.1:1 it works out to 3.9 for the final drive) instead of 1:1 like every other subaru transmission. So with the 1.1:1 gears in the center and the 3.7 in the rear, that should put me around 4.05 or so for the final drive.

How I made the rear diff work was I just bolted the whole thing in the car, changed axles, and changed the flange that the driveshaft bolts to. At least subaru's are like Lego's :)


Here's a peak inside that rear diff:

http://img116.imageshack.us/img116/1452/dsc02572medium4ee.jpg

word. clutch pack diff looks neat. i was pondering that calculations to be about 4.05 or so, its happy with the 4.11?

How did you blow second? You didn't have any problems with parts not in the rear end not liking 50% more power?

I don't know how I blew it. I assume it was from shifting too fast or that time I was playing around in a wet parking lot... Going from all 4 wheels slipping, to having traction tends to break things.

The rear stuff seems to be handling it alright. I have no idea what the long tern effects will be, but I guess i'll find out. I've been extremely nice to it. I still have to get used to RWD.

if I was running in AWD, the rear diff would have to be a 4.11. Without running the front wheels, the final drive doesn't matter to the transmission. THey only thing it matters to, is the speedo gear which is why I wanted to get as close to a 4.11 as possible (so my speedo would be somewhat accurate). The speedo is ran off of the 3/4 driven gear. The way the center diff is running, it's not sending any power to the front wheels. I've still got the front axles in there and everything.

So you're changing back? Just because of traction purposes or are there others?

"lego's"....lol....i liked legos....maybe thats why i love my subby!

I don't. :mad:

2 Questions:
1-Is this the pi**ing match thread or the RWD thread??? :confused:
2-What would be the purpose/benefit of switching a AWD to RWD??? :confused: x2

if u went RWD you can use a 2wd dyno. if you wanted to drift, you could do taht too. tahts about it

^
Doesn't seem worth it, does it???

U dont see me driving a RWD subaru.... i have a AE86 to go in circles with.

honestly, its plenty of fun FR. i also have a DCCD....

I'm going back to AWD. Mostly, I went RWD to see how my car would handle it. It handles it fine, although when I'm alone in the car, it looses traction about 5k (and full boost) in first gear, and almost all of second gear (Again, at full boost), and finally catches traction in 3rd. Although I've never dumped the clutch or tried a burnout. I'm going to put a 6 speed in the legacy with a Ver2 DCCD controller. I should have all of that done in a couple of weeks, when I have time to pull the current tranny, and add the 6 speed. I wonder if any other BD legacys are running 6 speeds :D

Although, I will say the donuts in the empty parking lot were alot of fun :)

I don't know what you're talking about. I never sent you any emails, and I would never make any racial comments. I don't know who sent it and know nothing about it, but that you just aim it at me with a bs filled post is a load of crap. I don't like the idea that someone emailed you with something like that, but I didn't do it. I'll excuse your comments because I didn't do it, but I think it would be a load of crap if you replied to this with cheek, as I did NOT send anything like that.

GOOD. ill assume you are telling the truth, lets just drop this thread.

Sounds good, and yes I wouldn't send an email like that, however, I'm curious who did. Sorry for the misunderstanding.

chevelle, whats with all the noobtastic questions? you remind me why I'm not on "drift" forums anymore.


WRX_driver_2002 bastege you stold my diff :p you are going to keep the LSD when you put the 6spd in right?

Well, I'm new to subarus....

then why are you posting? when i was a complete noob I didn't post, hence why I am still a "scooby newbie". just read threads if you want to know something look for it and read up on it. google is also your friend. just a little advice, from one noob to another.

thats nuts! i deffinatly want to see a RWD suby. it would be ridiculous to see a burnout! i can't even picture it in my mind. KUDOS!

RWD Suby would be pretty fun, but I like having traction

I switched back after a week or two, just wans't driveable as we had taken so much weight out of the vehicle...:(

:huh: it would be like every other rwd car, only not engineered for it.

i plan on doing the rwd conversion in a month or two and this is what i found out after doing all of my h/w

1- you need to weld the center diff or buy the piece from rocket rally 2- upgrade the rear diff to a r180 or a r200 3- get the rear axle from the r180 or get the stock ones to match up

am i missing anything?

Yeah. The only other R200 Subaru subframe in the world besides mine (to my knowledge) belongs to Kumakubo, who drifts the STi in D1.
Here is my car:

-Custom Mr. Anlet R200 subframe (S14 differential)
-Moser engineering rear axles
-Custom driveshaft
-Fused center differential

I think WRX_driver and I did our conversions around the same time. I know that I had already broken and replaced 2 axles by october and started working on my R200 frame by mid November of last year.

This is the center differential for Phase I 2.5l Legacy differentials:
http://www.locostbuilders.co.uk/upload/Legacy_Center_Diff--top.jpg
Notice that it is different from the WRX/2.5RS differentials. I'd be skeptical of the Rocket Rally center diff replacement working properly in a BG/BD Legacy transmission.

For RWD in a WRX, the center differential replacement from RR and an R180 subframe ought to cover it. Be prepared to replace your trailing arm bushings though, as the stock bushings make for a herky-jerky ride after being murdered by the torque.

^^^ so thats really it then? i plan on starting to buys the things i need but i want to get everything at once

Well, I don't have much firsthand experience with GD's, but I'd imagine that the more you beat on it the more things you'll break.

If you have stock power, you'll probably be ok with an STi rear setup and a RR/welded center diff. Anything more than that and you'll start stripping stepper gears, crushing trailing arm bushings and possibly damaging center bearings and driveshafts.

icic... im running up pipe, down pipe, boost controller, fmic, intake, fuel contoller, exedy street sport clutch, and exhaust. is there another way of approaching this then so i wont be blowing things up every weekend?

Is there another way of approaching this then so i wont be blowing things up every weekend?
Yeah, the problem areas are most of what I talked about in my previous post, and the solutions
-Swap your AWD transmission for a Nissan KA or SR transmission (the input spline pattern is the same for KA, SR and EJ transmissions). This requires custom bellhousing and KA or SR clutch disc sandwiched in your Subaru flywheel and pressure plate. Your existing clutch line might be long enough to relocate the slave to the side of the bellhousing where the Nissan clutches engage, but a custom braided line could be made at Amazon Hose. Starter would have to be messed with, but you could probably use either the Nissan or the Subaru unit with the right modification. I'm working on putting a W58 Toyota transmission in my own car and will keep posted
-Get a one piece aluminum driveshaft from www.DirveshaftShop.com and eliminate both the center bearing and the weak Subaru piece.
-Get improved/more rigid pitch stop mount, rear trailing arms, transmission and motor mounts.
-The Subaru R180 rear end is good up through something like 350 RWHP. I believe that the Nissan R180 is good for a bit more due to the shorter and thicker axles. Anything more will require the man-style R200, for which I could build you a frame.

With $2k worth of mods and many hours under the car, you could have a fairly bulletproof RWD setup.

Much to the chagrin of the anti-RWD'ers, I'd be happy to help anywhere I can when it comes to RWD Subaru :devil:

well im not running more than 350 so i should be good in that area... so basicly the r180 set up should be ok for me?

Should be. It will fit, but it's integrity is not gauranteed in RWD.

^^ very tru.. the drive shaft will not line up tho will it?

Wow mramlet, that's a wicked setup!
:eek:



To the original poster, I have a rwd conversion for sale now. It's been tested in my old car and worked well. I'd use it in my STi, but unfortunately the center diff won't fit in the new 6 speed.

As for why?
Because rwd is a lot of fun in the dry.
You can dyno at any 2wd shop.
Wagons doing burnouts trip people out.

Anyway, drop me a pm if you have any questions.
As for the ctr diff, I want $500 and it includes axle stubs for the front. They're not necessary, but I liked removing the front diff from the equation. Plus, axles are bloody expensive and I'd hate for you to hack up yours.

cheers!

Thanks on the compliment. I'm debating swapping to a true RWD transmission, but I like the idea of a converted AWD trans.

What is your center diff from?

Here's some inspiration:
http://www.megaupload.com/?d=4BB8ULDU

wait..does the drive shaft have to be shortened or lengthened at all to make this work tho?

On a side note. If you do do this type of converstion. Check your rear diff. make sure the ring and pinion have the proper spacing (Lash). Mine didn't and my whopping 142 bhp and 150 lbs at the rear wheels ended up ripping all the teeth off my pinion gear.

Its my own fault for not checking a ring and pinion that had over a 150k on them.

So any progress on the Toyota tranny?

I was thinking of pulling my wrx tranny for something that was designed as a RWD unit. I think it would save some weight. I might be able to get a diff and tranny out of a R33 GTS-t, any thoughts or would a S13,14,15 diff and tranny be easier?

hope you guys don't mind me picking your brains.

well...right now I'm RWD. It's really fun. I had a spare center diff so I just welded the side gear that transmits torque to the rear to the diff housing at four points. I have a 4.444 rear diff from an auto 2.5RS. Really fun running through the gears. I'm thinking about putting in the welded diff and attend an autocross.

The handling of it is really nice. There's really not anyore of that power understeer. Also at the limit, the car almost wants to come around when off the throttle. Get on it and it wants to come around. With the torque of the engine, there's wheel spin if you're 30mph and turning while in 2nd gear and WOT.

I have done a burnout, it's on VID, but....I still have to get that vid.
