- In this episode, Aaron goes over pros and cons to having a RWD Subaru and how to convert your subaru to RWD!
From stuck and broken bolts to a stubborn CV joint, you'll see a few mishaps that can happen during your conversion and how to overcome them!
*I don't recommend prying apart your transmission with screwdrivers, but do what you have to do.
*You don't need to put the inner CV cups on the axle stubs. It works just fine without them. You can also split the case and completely remove the front differential to cut down on excess rotational mass to maximize performance.
*I would recommend cutting the outer CV cup off and leaving just the stub. This removes the hassle of prying apart the bearing, while reducing excess rotational mass.
*Locktite is not required on the outer CV stub. You can torque it to spec just as you would a standard CV axle.

Hands down the most useful conversion video clip uploaded.
Hey there from new Zealand. I am currently doing my second manual swap. I watched your whole manual swap series about 4 or 5 times before I attempted it myself.
And it went so smoothly. I only use a couple of scissor jacks and a handful of loose tools. And I done it 100% by myself.
By the time I started the swap I felt like I had done it a thousand times that is to your videos.
I also worked out all the kinks with the wiring first pop.
The manual swap I am doing now is a bh5 auto. So there are subtle differences. However the biggest difference is the vehicle speed sensors from the original auto gearbox. There are 3 on the original auto box. And I'm not sure how I'm going to rewire it for the 3 wire speed sensor on the manual gearbox. But I'm in no hurry and am researching the hell out of it.
Just wanted to share the love and give you a huge thank you for your efforts.... And subscribed today...
+l33boy hey thanks!
I'm always happy to hear that my videos helped out!
I only started my research on the bh chassis manual swap, but never ended up pulling the trigger on it, so I never got as far as the speed sensors. Good luck with it!
Hell yes! Awesome vid. I def want to do this one day! Keep up the good work. looking forward to the turbo build
NIce conversion I like it
I started also back in Luxemburg with my channel for fun
And I like your position in the scene like low budget and do thinks whit the mony you have and not buy it all new an shiny ^^
going to be using this video for my rwd conversion starting today, thanks for the video man
OK this was pretty cool and liking the look of the turbo series and other vids will defiantly check out your stuff as seems we take similar lines of thought.
tailgates make great workbenches. yours even has an oil catch
Especially when you just let it drain through the bolt holes into the tailgate and onto the ground....
Great video. Also super cute
I havnt watched your videos in a couple of months because the video production quality wasnt what I personally like, but you stepped up your game lately and im enjoying your content!
+Burt Snakehole Ludgate Karate Dracula Macklin Demon Jack-o-Lantern Dwyer thanks! Anything specific about the new style? Or specifics about what you didn't like in the older vids?
Wood chisels work best to separate housings has a better taper in the pipe apart, release it without damaging the surfa ces, also CRC in a red spray can spray, it works great on corrosion have had things stuck together with rust sprayed it on, and they just came loose, good luck!

Also a dead blow hammer is the correct hammer to be waking on Aluminum.
My first subaru was a BD5 legacy 1995 with a closed deck ej22t from a 1993 legacy ss. I ran as2008 legacy gt 5 speed and a rear r160 lsd and was fully rwd. The car made roughly 300whp and was tuned on 20psi from a vf48. Check out RobTune for first gen legacy ss turbo tunes and other Ej20g stuff if you are curious. I should also ad that I went through many axles and a rear diff before I sold the car. Very fun, but in the end, a Nissan r200 with custom axles would be a better option. Or just buy an sr20 240sx. RWD subies a fun though!
Just a helpful hint, if you are using chlorinated brake cleaner make sure there is NO fluid left when you strike an arc or the intense UV will make phosgene gas. If you don't know what phosgene is, Google it. It's awful stuff.

I just started watching this video and I instantly thought get a secondary center differential.
AMAZING
I think grounding the diff directly would make the weld more steady, the contact points are too small on the table.
dude how long did those welds hold lol 2 inch stick out somethign like that id be doing some stick welding dirty dirty dirty lol
Does this work on all awd and 4x4 transmission?
Are you running wheel spacers to get those c4 corvette rims to fit your Subaru?
_so, what would i have to do if i put an engine from a RWD car into a Subaru? (keeping the Subaru AWD)_
Basiclly have 2 diff one welded and one stock that way you just easily switch it as you need to oh and find a way to put that diff in your car idk trunk or something so whenever you need you can just easily do it in a high way
Thank you for your video, one phrase confused me a bit:
you said: half of power will go to rear end, half to the front axle ( after welding) but if I understand everything correct, that after welding 100% of engine power will go to end and 100 to the rear. Correct me if I'm wrong
If you plan on keeping it rwd, I'd recommend taking the front diff out, it will cut out quite a bit of rotational mass
+Fox Mense yea, I was thinking about that. I'll probably do that route the next time I have the transmission out of the car or on the next tranny I build. Know of anyone who makes axle stub block offs?
Dirtcheapdaily no, most people including myself just weld a circular piece of metal in where the stub comes out(preload adjusters) its easiest to do it with the preload adjusters off the car so it doesn't warp,expand and crack the case. Also if you go use a phase 2 tail housing you can cut out alot more rotational mass because you only need 3 parts for the p2 center diff to weld it up, you ditch all the spider gears, and clutch packs. A fwd impreza rack is said to have more angle vs the awd one so if your going to drift that would help out alot. Just a couple tips for ya! Love the chanel man!
+Fox Mense sweet! Yea thanks for the tips!
Dirtcheapdaily no problem, bud! If you plan to put an r180 in the rear you'll either have to swap to sti hubs hubs so you can use the appropriate axels, or get a custom race(theres a guy on nasioc selling them) for the cv that let's you use the outer r160 joint on the r180 axel shaft and inner joint. Or go baller status and buy the r200 rear subframe, I forgot the company that makes them but it will bolt right up to the impreza and use all the stock suspension components but will allow you to run an r200 diff out of a Nissan. You'll also need a custom driveshaft and axels which will run about 2,500 but you'll never have to worry about breaking anything. The r160 setup is just enough to handle stock na power
+Fox Mense yea I've seen the subframe tss makes for the r200. that's the end goal hopefully, but I'll likely build it myself
so for me to get it right.... in the end you put the cups back on... you just leave them like that all four? no axle or nothing else? then just put in the diff?
Is it 100 percent power to the rear wheels or is it the same thing as awd power to not awd
Man I wanna do this! Just gotta work up the courage. Haven't done anything like this before
just as a heads up, you don't have to out the axel cup back on(the trans side at least, unless you have male axels) it will make no difference at all, it being in or out, it doesn't put any preload on the bearing, all its doing is sitting on the end of that output shaft
This is definitely true. I was thinking he was out of his mind.
So I just bought a 97 inpreza that was rwd converted as such front axle removed the stubs are still there not covered so I'm guessing I just have to replace the center differential ? And put the new axles back in ?
does anyone know what the weight differance would be after the rwd conversion, more/less weight?
Can someone explain how to bypass the parking lockout on the key assembly? He kinda mentioned it but didn't go in detail and forums haven't been helpful so far
Trop de puriste en France. Mais heureusement que vous êtes là!
En revanche le différentiel arrière tien-t-il le coup?
Merci!
Too much purist in France. But luckily you're here!
On the other hand does the rear differential hold the shot?
Thank you!
You also should have cooked out that oil in the diff, that's one of the reasons you have so much splatter, it's the oil in the metal exploding/burning. your welds also aren't going to hold very long with oil intrusion.
By doing this on an NA subaru, do you get more power to the wheels? In stock form, power loss is around 25% due to AWD. Even a 10% gain from drivetrain slop would be significant for an EJ25.
i was wondering the same thing.. do you technically there wouldnt be as much power lost through having it split through the front axles?
Same HP reading at the flywheel but perhaps on dyno this would show much higher HP at the wheels?
I think using less stick out while welding would help alot
What kind of front bumper is on the car?
So, if the power is split 50/50 and only the rear is spinning, does that mean you are only getting half your power to the ground? Example, if my car is 300 HP am I only really getting 150 of it to the wheels? Or would everything just be spinning at 300HP?
Nice, my 2000 rs is sti swapped and RWD Converted as well.
+V6RSTi sweet! Any issues with your rear diff or axles?
So you took one of the rare subarus and ruined it......why?
@@AndrewB23That's your problem, not his
Why were you loosening the bolts first by hand
Great video, been thinking of a RWD Subie Justy, but it doesnt have the boxer rumble so maybe a RWD Impreza or Legacy haha
+RiceFlavouredVTEC I've wanted a Justy for such a long time! I might have to get one and EJ swap it so that it would have that subie rumble. Having one RWD would be so much fun!
But I cant decide, RWD or 4WD Justy, both have their fun points, I guess 4WD for winter and RWD for summer haha
Is 2009 Impreza too new for this?
Brake fluid, sloppy welds, hacking shit open and then cheapen out on gasgets...the boys at Haggart would be proud of you
+Peter van Diggelen everybody likes a good cheapen gasget every once in awhile
informative vid. goood work !
What do you do for a living?
How do you tighten the outer part of the cv axle on the hub, isnt in spining when you tighten the nut?
+Dimitur Dimitrov no, it has the splines on the inner hub
@dirtcheapdaily where did you get the rear Audi endlinks?
+Casey Abbott Amazon, but you could get them from any parts store.
I hope someone is able tio give me some advice on how to do just the opposite of what is being done here.
I have an audi 6 speed manual ,awd, that I would like to convert to fwd.
I would like to install an lsd as well.
Now I am mot looking to run fwd.
What I am looking to do is use the transmission in a mid engine build.
Porsche makes a tranny that will work but it is outside of my budget.
I assume that this is possible.
Hopefully someone will chime in with some useful info.
Lol I’m sorry but that welding killed me definitely get a new welder lol
Can you do this to an automatic 1997?
If you can't mess with OEM than what the hell is the point. awesome vid.
Hey! What lip is that on the red Legacy bumper you have in the back of the truck? At around 5:50?
+Artem Lavrynenko it's Stock for the GT trim
You guys should dismantle the Earth/Ground clamp for the welder and wire brush the inside of the clamp. Carbon buildup inside the clamp will make it struggle to weld at higher output. Great video tho!
Also, to get broken bolts out, get a centre punch, tap the centre of the bolt and then use various sizes of metal drill bits, I start with 3mm and work my way up. The bolt usually collapses when theres 2mm or less left on the outside. Tape the drill bit to the length of the bolt to prevent drilling through the length of the bolt.
booger weld that centre diff lol... can you weld the centre diff and keep it awd? would it make it 50/50 all day long insted of moving the power around.
+sr20nissan 720 you could, but you wouldn't really be able to turn. The manual is already 50/50 pretty consistently. It's the automatic that really shifts power around
Can you just buy the center diff already welded?
You can buy a spool
i have a 2007 single cam non turbo 253… i’m using so much damn gas with awd that it makes a ton of sense to do it. it’s a five speed to so makes it kinda fun… the other thing (on the topic of people saying don’t buy a subaru…) we like the boxer motor? are people that ignorant? id put a ej257 in an s2000 if i had the cash
hey i wanna do burn outs and drifts and all that what would i need to do to my subaru to make sure it wouldnt break down
Trade it in for a bmw. Lol
That's some dirty nasty welding... But of course that thing ain't gonna turn with all that crap in there.
Even if it gives way I think (with my limited AWD knowledge) it should still be safe enough.
There is subaru. Front wheels are lifted on jack stands. Center diff is open, but if you press gas rear wheels spin and car falls off. If center diff is open shouldn't it send torque to front wheels? And why it's that? Please answer.
+Gedas alekveravičius I have no idea why you'd try and spin just the front tires, sounds like a good way to get hurt.
The majority of the power is going to the front, but on a manual transmission, the power is split 50/50 front/rear at all times, so the front probably did spin, but you dropped off the jack stands. Please don't do that again. The car is AWD, it needs 4 jack stands/lift
you dont even need to put the axle inner cups, there are Bearings, races and seal that hold the front diff in place like the previous person said take out the front diff.
I can't find a matching rear diff so I'm doing this now
well you are a dead shit idiot !
On a RWD car you need much more caster angle. I guess right now your steering wheel is totally numb.
I don't have a welder. Do you think JB Weld would hold up?
So it still sends half the power to the front wheels ?? Is there any way to make it so it just goes to the rear wheels ? Am thinking on doing it to one of my spare gearboxes just need to know all the options as I just want strait rwd
+Guy Heidenreich without the axles in the front, it's basically just freewheeling. It's putting some power up front, but the majority of the torque will be coming through the rear. You can check out my manual transmission teardown video. Near the end, we go over a few options for RWD. You could pull out the whole front diff and plug the axle holes, but you'd still have an axle spinning up front that doesn't do anything.
Hi, yes i have done this on an old gearbox. i didnt have much fun with it tho cause it killed the power alot.
i was running .9 bar boost at the time but couldn even get sideways action
Don't want to rain on your parade but those weld look weak and cold, probably sheer. At-least the centre diff looks easy to replace.
+Forged Shaft it took 4-5 hours before I could handle it without gloves, which I know doesn't necessarily mean a whole lot, but even if the welds do crack, there's not really any way for that diff to start turning with chunks of weld filling up the teeth.
But like you said, it's pretty easy to get to, and I have access to 2 more if I need them. Guess we'll find out!
Forged Shaft - Dont worry, it was really hot so you know it had good penertration......
you can just beat it off XD 33:31
That housing is trashed! Never use a screwdriver between the housing. Great way to make a permanently leaking case.
For what purpose? Drifting?
+TheRabidfan that's the plan
Well... um... to be exact... yes.
Think you could do it to a 98 or 2000 impreza 2.5?
+SolarTara easily
Wow thanks for the reply man, subbed ahha. Awesome, going to be doing it myself
Please don't ruin a rare subbie
why do people not try practicing and set up a welder before they do this stuff, and then blame the machine
dont forget to use your safety squints while hammering stuff, you dont want a chip of rusty metal in your eye, trust me lol
Hey man do you know if rwd can be done to viscous center diff for 2001 Forester b4 I buy this donor car
+scrubturkey if it's a manual, yea. I'm still trying to figure out how to do it on the autos.
Dirtcheapdaily Manuel every time for me and I like your channel keep it up. I was looking at sr20 swap then ej20 swap with rwd and your channel made up my mind subie rumble in Toyota 3am here sleep time
scrubturkey388 just made it now
Why go from AWD to RWD?
What if u were to weld the front axles stubs stiff won't u get 100% power to rear
what would you weld them to?
Dirtcheapdaily hmmm good point lol. Could make a bracket thet tap into the block I guess 😌lol
+Driftprodigy01 I've thought of trying something like that.
It'd be sweet to have solenoids that can lock the front inner hubs and still allow the outers to rotate so you could just flip a switch and go RWD on command.
Dirtcheapdaily Yh that would be sick I wanted to buy the audi s5 v8 but its awd thought about doing this but idk... Keep up the vids cool build
use non chlorinated brake clean so you don't die from fumes when you weld
what about making a Front wheel drive Subie???
Same thing. You can get a fwd transmission, or just wed the center dif and pull rear axles.
Who do you think you are to comment potentially hurtful, ignorant, things on UA-cam?
I like the fact he is using a chevy to fix a suby!!!!
+Leroy Jankins gmc ... Lol!
Then you'd like my subaru loyale l use to fix heavy equipment l get some odd looks in our yard from guys driving sorry about your penis trucks.
so this will work for 96 manual impreza? saw that you are working on a legacy
+Flynn Mckeogh yup! I'm using an Impreza transmission. They're the same thing
Sweet! Love the vids bro, i was told that i don't have to worry about the front cv's
+Flynn Mckeogh like leave them in?
You'll definitely want to pull them otherwise you'll get major bind hahaha. But yea, you don't need the cups on the axle stubs, just in the wheel bearing
Figured as much :) thank you for your reply 😄
+Flynn Mckeogh yea no problem! Glad to give you ideas!
Do you have a TY752 or a TY754?
+Gavin Alexander no idea
Actually you can do this with no welding what so ever. Just tap into the centre diff solenoid (just under the dash on the driver side). You can tell it to lock up (on demand at the flip of a switch) and voila RWD.. of course you will need to uninstall the front CV axles.
That is awesome, maybe a future DIY.
PLEASE don't tell people to use brake cleaner before welding. It can break down into extremely harmful compounds such as hydrogen chloride and phosgene that can literally kill you or basically ruin your life with minimal exposure.
was it brake cleaner or brake fluid?
Well actually you can use brake cleaner as long as it's chlorine free
yeah just use alcohol
just boil it or hit it with propain
Lmao dude you’re hitting it something that gives… hit it on a hard surface
Does this work on manual trans?
Yes
Awesome thank you I watch everyone of ur vids
will this work on a Dodge stealth rt twin turbo, since is has turbo's?
do you thing it will work on a 2004 subaru impreza rs and a 200A welder will work
+germain duclos yup!
Dirtcheapdaily thanks man
+germain duclos no worries. Good luck with it!! 👍🏻
Dirtcheapdaily i just did it its work good but now i got steering vibration now over 80km\h do you have a idea whats it can be
+germain duclos did you put the axle cups back through the hub?
Dude ... I get what ur trying to do and its sweet that you share it on the web to help ppl that dont know how. I also feel rwd subarus are not my cup of tea but i understand and applaude ppl that do it, its a very creative and cost effective way to have fun.
However you should consider yourself an educator when doing this, you have to be aware that you have a rollmodel function going on.
How do you justify, being an educator, hacking a job up like that ? The splitting with flat screwdriber, the horrible weld on the diff then saying its the machine, you knock off dust covers off of the cv-cups even though they serve the important job but you fail to machine down the cv-cup to cut down on rotational mass, you put cv-cups on the diff even tho that has no purpose other then eating hp in rotational mass , then you locktide a nut that should have no locktide at all because it has a splitpin and it will be hell to disassemble in the future but you dont torque down the locktide-d nut imediatly so it has time to set, not torqued and effectively taking away all the advantages of doing it in the first place?
The one that really made me fysicaly sick was the fact that you put in a cv-cup with the actual cv-joint half assembled in the car ? Do you know what kind of damage hardened steel pieces like the crown or ball bearing or housings do when they fly out at 60mph ? I hope to odins beard it only damages the road surface or the car but if it hits you or bystanders you could end up in the hospital asking yourself why.
Take your responsibility and take down or edit this video so people wont think its ok to use these dangerous methods !
Hey, thanks for the input! I've made a bunch of changes to the car and the RWD setup since I made this video. I'd already addressed most of the issues you brought up, but I never updated the video to reflect that. I just added a few on-screen annotations to clarify what was actually done, along with similar caveats in the video description. I always encourage viewers to do their own research and not to use my videos as their only source of information. My goal is to give that extra boost of courage to those who are on the fence about a project so they can enjoy working on their car themselves.
Its never gonna hold, been there done that, keep trying tho! Not good for the seals
FUCK that, I live in Jersey where it can be 75 one day and a inch of snow the next day lol I will keep my AWD Subaru lmao but by all means, have fun with the RWD, im sure its dope
Also have you ever heard of Penetrating fluid?
why couldnt you take out that front diff
+I AM BLANC you have to split the case to pull the front diff, which I didn't want to do at the time.
cracking bolts with a ratchet :O
Dont use brake clean to clean before welding, it can potentially kill you....
Only the brake cleans with chlorine in it.
The Walmart brand doesn’t have chlorine in it.
You can buy an electric impact wrench from Harbor freight really cheap. Then you don't twist off your bolts.
I have one, but I didn't have it on hand at this location. I honestly don't think that would've helped much though. The thing was completely seized in there
I watched my dad remove exhaust manifold bolts from an antique tractor that had been rusting for 45 years. He soaked them in penetrating oil daily for 2 weeks and then rattled them out with an impact wrench.
Don't forget its so easy, just like baking a cake, btw the axle does not hold your wheel bearings in
After reading your previous comments I can tell you are a real arm chair critic. In this case, you are not correct. The bearings are press in, but without the halfshafts to "pinch" them in place they will eventually just fall apart with side load ie: cornering.
Time to go be a baby driver now.
"you can use brake fluid as penertrating spray" ???
Really? Who told you this? And how did you mot call BS when they told you?
I would have just bought a new transmission
Just not awd
this is silly, just put the fwd fuse in and you have front wheel drive only with much better handling and gas mileage, why go through the trouble of making you car handle worse in performance
Stay away from my car!
LOL. I was thinking the exact same thing.
yes sir me also = he should have a honda !
Dude... welding + brake cleaner = phosgene gas = permanent organ damage or death. Do not use brake cleaner to clean parts before welding.
Not if it's chlorine free
