Can these things be converted to all-time RWD/ part time 4wd? Maybe turning the slip-fork around? Something along those lines?
Can it be done, how would it be done?

3ACPower figured out a way to do this. I think it involved fabrication of some custom components. If you do a quick search I'm sure you'll find the original thread too...

when i started racin i wanted to put a t50 from a ae86 in my car making it a little bit lighter but no luck finding one, plua i could use the diff of the same car with the benefit of the lsd

. .. Huh?

I searched for RWD and found that 3AC found an auto with a fried front diff that made it essentially RWD, but no 4wd.

You would probably need a different (custom?) front subframe to lower the engine, right? I've thought about this too.

What of a RWD/4WD system? As it would be nice as a drifter (thought behind it) in combo with a higher power engine, but at the same time, it'd still be nice to have the utility of a snow/ice-beast.

To retain 4WD, I think you'd have to either modify the Tercel tranny or use a Corolla T50, a transfer case and a different front diff/axle. Not worth the trouble in my opinion.

i just wanted to be rwd, the engine in that configuration drops2 inches and you can use the original motor mounts just have to modify them

So can you internally modify something in the stock tranny to flip the fork around that makes it engage so the that constant part is on the rear versus the front?

I think it will be a lot harder than flipping anything around. I doubt the transmission has any provision for disengaging the front wheels. I'd suggest dropping off a spare transmission and a few credit cards at a machine shop and tell them what you want.

What happens if you just take the front CV's out and put the car in 4wd? Can the rear diff and axle take 100% of the power constantly? My Front Diff is ready to die so I might try this soon.

We did that with a mate's Subaru sportswagon once.
His CV joint cracked and wouldn't seal, so we took it out.
The suspension flexed fine, didn't buckle at all. It had McPherson struts, like our cars. We left the top joint casing in the differential so it would still be sealed and put it into 4WD.

It drove like a dream. No transmission windup, as there was always a point where the transmission could get rid of any excess torque. The rear differential had enough grunt in it to take the power from the engine and considering this feller was a nutcase driver that was impressive.

We drove it like that for about five months, through snow and ice and all sorts of crap in a Tasmania winter and were most befuddled by the change in the car when we put the new CV shaft in and had to go back to a front wheel drive car.

I want BOTH FOUR WHEEL DRIVE AND REAR WHEEL DRIVE. Check that. BOTH FOUR, thats 4, WHEEL DRIVE AND, thats & or und, REAR, you know, the back, WHEEL DRIVE.
It seems every response since a stoic No, I don't think it'll work, is: Well, you could just fry your front diff. Remove your CV joints. Otherwise DISABLE the front. I DO NOT want to kill my FOUR WHEEL capability.
Now, the ideas are cool, for someone who wants to have just RWD, and they are out there, but that is not me.
I live in Colorado folks. FWD and 4x4 vehicles sell like hot-cakes here. Want to know why? We have white, slippery stuff that falls out of the sky and makes the unexperienced either DIE or just get scared and panic and get hurt. RWD does not go over well in ICE and SNOW. Back me up on this Canadian club-mates.
I live in the mountains. Mountains are steep. Mountain roads get SLIPPERY in the cold, wet weather. Its a fact of life for me here, and as a Coloradoan, I know how oversteer works... Especially as one who dirt and ice drifts occasionally. I also know how SLIDING SIDEWAYS WITHOUT STOP works, why don't you read my post on why I had to transfer my working engine into a Tercel with a straight frame? How about when I understeered into a ditch and fried my passenger front door as I went in then lifted a few feet in the air then SLID 12 feet just avoiding a boulder. I was not in 4wd. Ice is no toy, it is nothing to be screwed with. It can and will kill you. RWD has less moving traction than FWD or 4x4. If you don't have damn good tires, it does not work right and is dangerous. I'll get some pictures up of my dads old truck tires that had problems last winter in RWD.

I KNOW that I'm coming off as a jackarse, but I'm a little stressed right now. My moms Ex's turbo might be ready to explode and I take it very personally that its going wrong. My dads steering rack is moaning for no bloody good reason. My campers batteries died and thats no cheap replacement. My boat is having both charging and bilge pump issues. Both my older sisters are having developments.
lol.... Whine whine moan moan.

Am I looking at retro fitting of a 4Runner transfer case to a Corolla tranny?
Please give me some honest thought here... Does anyone have a detailed diagram of the inside of a Terc tranny? I want to see how that transfer cup works, if the system can be coaxed into reversal. If the system mates front to back, see if it can be made back to front. 2 slip shafts or whatever it uses will cost a bloody massive amount less to have machined than a whole tranny rework, althought thats what I may face if I retro a beast engine in there. I want a Chromium Molybdenum gear and shaft setup that will laugh at a Powerstroke V-8, though Lord knows that won't happen.

God I must be coming off as a jerkoff to new members. Sorry guys.

Problem is the transfer is on the rear. My idea is basically remove the transfer hub and join the shafts, relocate 5th gear back there where the transfer used to be, it can share EL's shift fork and hub. Then put the transfer in the front of the tranny where 5th gear normally is, and add the linkage required. Lots of work. It may be easier to add a transfer in line with one or both of the front drive shafts, then you can lock the original transfer and not need to otherwise modify the tranny.

Relocating a whole gear is not easy, so alternatively you could make a plate to go between the bellhousing and the tranny to create extra space for the transfer. Then there's no screwing with the shift rods, shafts, forks, heads, detent balls, detent springs and those things. The plate would push the whole tranny back, so getting it in would be harder. Keep the plate as thin as possible while still having space for the transfer. The plate would also include a transfer shift linkage.

One side of the transfer would fit the end of the output shaft and the other end would fit the pinion shaft of the front diff. If a suitable size transfer could be found, it would just have to be adapted to fit these shafts. Then in the room that you free up in eliminating the rear transfer, you could add another gear! Or else have a FWD/4WD/RWD setup. Use FWD for better mileage.
