Doesn't the rear drivetrain usually only have 10% of the engine's power fed to it? Is it safe to put 100% to it?

I think it's 65% rear and 35% front but I could be wrong.

It's been done before, theres even a center diff kit for WRXs to do this and keep it reversible, and I do believe the torque distribution favors the front wheels.

Unless im missing something here... manual trans cars have a 50/50 power split...

Autos (4EAT not VTD) are 90 front 10 rear most time, with ability to transfer up to 50/50 (ive also heard dropping it in low gear will keep it 50/50 but ive never cared enough to try it.)

I believe our center differentials have a Viscous fluid in them, and I don't think I need to go into how that works. Not sure where I read it, but that's why Im saying that. and AT is not always 50/50, I once put my front tires in my AWD slushbox 2.2 in mud, put the car in reverse, and then floored it. Lotsa spinning front tires. Then a LOUD "thunk" and the rear tires started turning... quickly... I believe AWD tranntys are computer controlled whereas the manual trannys of this generation are controled by the above mentioned Viscous crap

nyahh...you guys are funny. hahaha. The manual tranny's center diff functions like any other differential. It just has a VLSD on one of the side gears that try to keep it from spinning at a different speed. It functions just like an open diff but has some LSD effect.

The Autos however have a planetary gearset that slightly is biased more front on the older Subarus and more rear on the newer Subarus. It's very similar to the CUSCO Tarmac center diff, except that the CUSCO tarmac center diff doesn't have LSD effect.

Anyway, I plan on getting a tranny to do a RWD converstion on it; '93 AWD 5spd Legacy tranny. I have a RS tranny on my '99 L Sport Wagon.

Get videos!!

the R160 rear diff should be able to handle stock power levels, for a time, i expect bearings, axles, and regular fluid changes to be some of the things to do, however, there was an article in SCC about a wrx that was slightly modded that went the RWD route, he toasted the rear diff in a short time. If you do this, good for you, enjoy it while it lasts, if your good to your car you shouldnt have too much trouble, but our cars came from the factory with AWD, and the car's components are built as such. should be reall fun though!!!!.........mmmm...corners....mmm...no understeer.....

You're an idiot

Here's why.. The Subaru does transfer 50/50, but the drive shaft IS NOT MADE to handle 100%, nor is the rear diff. You'll break something in no time. Though, it's your car and you're free to do whatever you want with it. Just don't come whining when it breaks

settle man,.... The subaru driveshaft is way overengineered for the vehicle. He should be fine as long as he doesn't throash to much. I would be worried about the rear diff. But just put some redline gear oil in it and go have fun.

How about this one. So you do a little tuning and bump up the power twice as much as stock. Yet you still don't break anything. Go figure.

Think before you post, it's been done before.

yeah he should be fine, i know i couple people who have done this in their wrx's for the safety off taking their power stresses off the tranny, since it is cheaper to replace axles than a tranny

I'm running "280" hp all to the rear through stock drive shaft, R160 (granted it's a mechanical diff), and STi axles. At least for this week. Get fatty tires in the rear--you'll miss the extra grip at WOT.

I made 145 awhp and 156 torque... so i doubt the drive shaft can't handle the few extra ponies ill be producing from the drivetrain loss going down...


heres a pic of the work we have done today

Hey lachlan how the crap do you get the shifter linkage outside pin out, I got the inside one out no problem but the outside one is the last thing i need to take out before i take my center diff to go get welded

Can't help you there, I didn't actually do the work on the center differential. Check the tranny forum though.
