Flipped Audi trans with the bellhousing rewelded, hard to even see the joint.

Image may have been reduced in size. Click image to view fullscreen.

So this is a audi bolt pattern but whats to stop this from working with a 1.8T or TDI convert with a Passat longitudal mount 5speed trans?

Is the starter direction a game killer? Axle flanges?

Very interesting.

I actually considered doing exactly that with my 1.8T project, but I didn't like how high it raised the inner CV joints in comparison to the outers. Probably not an issue on a lowered, or maybe even stock, height van, but on a higher van, I think that the CV angle would be less than ideal. Cool to see it done though. Where did you find that?

What Audi is that transmission from? I wonder how well the shift rod seal will hold up. In a stock configuration, the shift lever would be above the level of the hypoid. I can not see the welds, but it would require a very skilled person to do with a fixture that could hold it centered. You would have to fight warping and it would need to be precisely centered to work. Otherwise impressive.

@ Chris - http://www.brick-yard.co.uk/forum/charge-cooler-and-new-gearbox_topic62757.html

Good point about the CV angles.

@ Vanagon nut - I meant the physical starter location. Ours hang over the trans, that audi has it beside the engine block & i'm not sure with the longitudial passat installs.

I'm guessing whomever welded the exhaust didn't to the bellhousing Wink

Audi's used an engine side starter, opposite of the Vanagon. I can just make out the starter I think in the one picture. I think fitting the starter with the turbo would be tight, but it must fit. As long as an "engine side" starter and matching flywheel are used, it should fine. The engine will always turn in the same direction regardless of the transmission.

I can't say I'm favoring the exhaust or engine carrier welding
and I'd like a better image of where the Alum bellhousing was welded..

the Audi CVs were larger than the stock vanagon so it wouldn't be too tough to adapt to a Porsche 930 CV to handle the angles..

this is only for a 2wd modification,

I would be concerned with how the internals woud get oiled and how long it'll last..

the starter is in a "stock" locaiton it doesn't even know the trans was rotated

I have a Formula Vee engine adapter for an inline 4cyl that's made to be on a flipped beetle trans.. not that that adds anything to this conversation though..

It's an Audi 012/01A gearbox.

I'll be interested to know if anything has been done about the oiling inside the gearbox.

If not, the diff bearings won't be getting any oil and will run dry and die very quickly.

Nice idea but it looks a bit half thought out. Fingers crossed that the input shaft has been lined up carefully before the bellhousing was welded back on too.

I think the internal oiling would be fine, but I agree with Mark's concern about the shifter seal. That's a fairly light duty seal and I don't think it's really designed to have the oil capacity against the back of it.

I'm guessing that is a 2wd version of the 01E transmission that Audi used on their higher output cars starting in 1990. There is the 01A which is for lower powered cars and then the 01E which was used on the URS4 etc. The Porsche 968 used a version of this transmission on our side of the pond.

Interesting idea, and pretty cleanly done. I'm impressed with the installation.

I'm also wondering about oiling, unless the tranny was filled completely to the top I would be worried about how it would oil everything.

Seal the "top" side of the tranny and add a breather/reservoir somewhere and fill it to the top........

All this does is re-awaken my north american Eurovan AAB IDI to 5cylinder mTDI dream. Identical in theory to my AAZ-mtdi. Just need the head & a few other bits from the UK.

The engine mounting tube looks like one I saw for sale here in the Samba with a package deal...........Quantum 5-cylinder diesel, South Africa Bell housing, mounting bars, etc..... looked very similar if not the same!

Years ago, my uncle and his brother-in-law fabricated an engine adapter to mate a 4-in-line Rabbit engine to a '69 beetle tranny for his rail buggy...... it was a rough looking adapter. However, it worked well! I do not recall how they centered it!
