VAG/Porsche transmission options?

Slow and steady. I've got a solution for the oil pump on the ALH and late 1.8t engines.[/quote]


For a '03' 1.8T too ?[/quote]

Yes for an '03 1.8t, it is the same oil pump used in the ALH TDi.[/quote]

But what about the reversed rotation of the pump ? How is that achieved ?

If the crank turns the opposite direction, then the pump will not work unless reversed ? Yes ?

Oops...yeah, that's the best option available.



How's that reversed TDI coming?

Or reverse the flow being fed into the transmission. It's been done here in the states.

You have to flip the entire 012 in order to reverse the flow. It's been done quite a bit in the UK

We're all talking really about spending more or less money to make one or another option work. So, why not get a group together and go with a custom reverse cut R/P for the 012. No flipping gearboxes, no custom plates or adapters (except axle shafts), just bolting together.
I'm thinking about that avenue ever since I saw the Subaru reverse cut R/P. I inquired with 4 custom shops, who make mostly off-road and custom R/Ps for North American vehicles like jeeps or pick ups. The lowest production run quantity I was quoted was 200 units. Ouch. But maybe someone knows other shops or manufacturers ?
If I'm thinking of dropping at least $1500 into a clapped out old Porsche tranny (plus adapter ?!) and then upwards from there, why not spend the same on a custom R/P for a tranny that fits physically and in respect to gearing, etc ?

I doubt GW is going to come through for their customers for much of anything new and different in the trans department. However, for the purposes of beating the Japanese van at LeMons, they can and should think outside the box. My solution would assure victory for a Volkswagen powered van entering the race as a Volkswagen.

GW still does not have a 6 speed G50 transmission option for our vanagons?
They are such slackers!!!

I certainly hope GW has been paying attention to my calls for them to counter the Japanese LeMons van with an all VAG mid-engine 1.8t and five speed transplant. Way better torque characteristics, gearing, fuel efficiency...and provenance.

Interesting concept. I'm not familiar with the 01E, but full power is first sent through the center diff prior to being sent to either the case diff or divorced unit? If so, then that seems like a plausible option, albeit an expensive machine shop version.

I've been holed up in Casa de Chaos finishing up a longterm vintage Mercedes project, but the final details are so tedious that my mind has been wandering back to bluer skies. The LeMons thread prompted me to revisit an idea I had some time ago. Seems like the easiest and possibly lowest cost means in which a person could completely repower the entire drivetrain of a 2wd van, would be to locate a cheap 1.8t Passat or fwd A4 (and they're dirt cheap on Craig's site), and install the longitudinal drivetrain in its original orientation as a mid-engine configuration. The inner LCA mount spacing should be sufficient to accommodate the arrangement, which would obviously necessitate re-configuring the horizontal frame rail.

My crude calculations have the forward section of the engine ending up roughly where the rear seat begins. The rear seat would need to be either raised or split into three sections, with a raised static section in the middle covering the engine. I believe the Boxster used a version of the 012, so there would be guidance for how to set up forward shifting on a rear mounted trans.

Lots of 012 trans are geared pretty tall, like 3.7X, but there appear to be some with 4.12 diffs. I think some versions even use the same CV flanges.

I'm kinda halfway seriously contemplating a mid-engine 012 with an ALH for my rig, but if I were to build a LeMons van, I'd definitely go with a 1.8t. Oodles of easily tweaked torque and a stronger trans all in one very complete relatively easy to wire up package. Are you listening, GoWesty?

Okay, Casey. I have started a comment a few times and got sidetracked, but here we go.

What about using the Audi 01E AWD transaxle? The adaptation would be to replace the centre torsen diff with a planetary gear set that would reverse the rotation. An optional approach would be to use another means to reverse rotation and use a planetary gear set for a low-range feature. Another option would be to use one set of combination planetary gears for both the reverse rotation and the low range feature.

Apart from reasonable strength of this transaxle, the ability for the 1.8T engine to mount up is a bonus.

This approach would require some creative thinking for a locking diff or LSD or TBD in what would become the "rear" diff. For the "front diff", the Audi rear diffs are available with a vacuum-actuated diff lock. The unknown is how well the Audi R&P sets will cope with reverse rotation. Andrew Flint's experiment with the 02A transaxle, a less heavily-built unit, suggests this might not be an issue.
