The easiest transmission for this would surely be the 911C4 trans. They are not that expensive and will be able to withstand a lot of power.

Well, my daily driver needs the work ( and $ ) more than my project car at the moment; but, I started asking around for prices on a good used C4 tranny and so far they seem to be in the $2500 to 3K range.

Anybody got any leads that are cheaper?
(I've contacted 20th St., Oklahoma Foreign, dC Automotive, & some local places)

Hi
Just getting back to the Subaru trannie or Audi for that matter. I saw an open wheel race car once using a late 1303 box with a single side plate, the trannie was turned upside down to reverse the crown wheel. Just a thought I had that this maybe could be applied to Subaru box or Audi.

That's a very interesting idea...it never occurred to me...a very simple solution.

It deserves some more thought.

I have seen an MGA ( with a Ford 351 W ) that used a Datssun Z car Diff .. that was inadvertantly mounted upside down .. was quite a shock to have 4 reverse and one forward speed. Unfortunately the Subaru has a dipstick so does not lend itsel to being inverted ... also I dont know about oiling ? is there an actual "Sump" area? how would oil flow be affected ? As soon as I get my house a little more moved into I will be tearing apart an 86 Scoobie RX I will let everyone know about the tranny as soon as I can. It looks as though with a little judiscious grinding I could possibly flip one of the older ( mid 80's ) Subie tranies but have not persued that any farther as I quired the newer no dual range one in the meantime.

lets keep trying ( also the VW is not that difficult to convert..... there was an offer on one of the other threads)

 I must have missed that...the construction of an extended nose cone to support the extended pinion shaft is necessary to use the stock VW box. If Joe L. is out there (or his son--who owns the 4WD Rally Bug), can you guys whip up the nose cones?

Doug I might be getting confused here aas I dont know the people here well yet. In another thread which I cant find right now, the owner of the Oregon based shop ( I think the one that does the upright conversions ) said he could handle the extended main shaft... leaving the nose cone up to the Builder ( as you stated )

The one I was around ( though it has been near 20 years ) was simply bored through for the shaft with a counter bore and a seal.
I am thinking ( again I might be oversimplifying ) that if a guy didn't mind a rather " square " looking nose cone that a lathe might be able to handle the job. I simple block with a bore through for bolts, one for the main shaft that was stepped on the inside for a bearing and on the outside for a seal. Maybe there is more going on in the nose cone than I think. I have an offer though. I am setting up my bench ( my whole house ctually ) I have a 9" lathe. If someone can provide me some guidance and wants to try this... I can bore a Block to accept a bearing ,shaft and seal. Put some research into it. I wont be able to handle it tommarow as I still have much work to do to get the lathe ready, but in the "near future" If you are serious and Know what you need, contact me I might be able to help.

That would be Joe. He owns Oregon Performance Products, and his son (I believe) owns the Blue Rally Bug everyone is talking about.

Now that I think about it...I do seem to recall Joe or maybe it was his son mentioning that they could make the extended shafts. I suppose machining the nose cone wouldn't be too-too bad...I'll have to go back and look at a tranny again, and ponder this. Although I am partial to using a tranny already engineered to be AWD.

If you're really interested, you could shoot Joe an email. He's a great guy, and always seems ready to offer info/advice.

Once I've got my driver back up (just an exhaust/CDI install, and ign timing/valve adjustment away), and I finish my GF's "honey-do" lists, I can get back to my project. Having other folks discuss this AWD project gets me stoked, my GF better hide the credit cards or we're in trouble!!!

Repositioning a dipstick shouldn't present too much of a problem, and a pump could be used in conjunction with properly placed hoses to ensure lubrication of the tranny (been done quite abit with Porsche 915 5th gears).
