Bit of a hypothetical question...

Here is a photo of the Subaru gearbox internals..
admittedly with non standard straight cut gears




You can see the front diff on the right hand side of the photo

Would there be any reason why someone couldn’t use the Subaru gearbox as a RWD middy and just leave the rear output shaft unconnected? perhaps enclose the output shaft on the grounds of safety/ keeping grime away

It could be a relatively cheap way of getting a powerful middy engine


Your ideas are, as always, greatly appreciated

Isn't there some sort of clever front/rear differentially-thing in there? So would the unloaded shaft just spin freely?

Is the front diff strong enough to deliver all the engines power through that alone continuously...?

Good idea though, since the Porsche transaxels are not getting cheaper...

If i remember right the center diff should be on the back of that gearbox.. or thats a front wheel drive box..

we looked at the subaru middy thing as a sorta what if, wouldnt that be cool to do if we had the time thing we had a look at the internals of a legacy 'box albeit with the hi lo selecter, but pretty sure that the center diff would need welded up.

the other thing we noticed was with the length of the box you could end up with the box poking out the back of the car!!

The subject has come up before, I think you either lock up the rear drive someway or go 2wd box. Here's one prepared earlier...http://www.locostbuilders.co.uk/viewthread.php?tid=77970&page=1

There might be some info for you here :- http://www.oz-clubbies.com/forums/index.php?showtopic=9106

or your could pm Kaspa on this site [or OzClubbies] as he's currently building up a track only version

Unless there is something hidden in that picture, I see no reason why this should not work as suggested.

Nothing needs to be locked, the unused end of the output shaft is just the same as any other unused end of gearbox output shaft. In its original set-up it would have had a load applied to it, but in the proposed use it won't.

As far as the safety thing is concerned, when the sticking out part of the output shaft is turning, the car will be moving

The length of the gearbox is OK too, as the wheels, which will be on the centreline of the front diff, will extend at least 300mm backwards from that point.

Theres def something missing in that pic, the center diff is part of the gear box in a subaru.
