Cool thanks for the info .

Ring and Pinions switchable between different cases? That is diesel to gas cases . Different number of case ribs .

Who do you buy gears from ? Thought AA was the go to guy but apparently he wants to build transmissions not just sell parts . That's cool , and I get it . Just looking for another solution . Don't really want to ship my tranny to the other side and back when I'm comfortable taking care of it in house .

What would be ideal r&p ratio and 3&4 to match ? That is running an ahu .


My AHU westy had a 4.57 R&P and a .77 4th, 3rd was 1.17 IIRC, and I had 27.5" tall tires (10% more distance per rotation than stock tire size) and I though that combination was just about perfect, 2750 RPM at 67 MPH. (vag-com for RPM And GPS for speed)

Reading on gear ratios the dm code has a 5.43 r&p is that correct? It seems to be the numerically highest ratio you can get . I have trans from an 85 doka . I believe it should be a 4. 57 or 4.86 ? The case is shot . Any reason why that r&p wouldn't work for me ? I still have to see about 3&4 gears . But usually bringing down the r&p when you up power works well and helps cruising speeds .

What would be ideal r&p ratio and 3&4 to match ? That is running an ahu .

You will want taller gearing for either engine, but the TDI will require custom gears. AAZ is happy with stock WBX or air-cooled trans gearing. I think your $1000 estimate for the added cost of a TDI install is low unless you are comfortable personally re-gearing the trans and building the mTDI pump or doing the wiring and don't give any value to your labor.


If I were to put on of my AAZ's in it would be done as a full rebuild . I'd have @ 1K in it plus my time . My AHU is good to go except a t-belt. I'd outsource the pump work . So that offsets money saving of the ahu not needing a rebuild . Ahu will save on rebuild time . Either way I think I'd regear. Anyhow , I've got the choice of either motor . Theyre sitting at my shop . So , tdi it is . I will be building my own trans .

Right now the van has no ac or ps . I'd like to add both eventually . I agree with you that v belts can cause less stress . But serpentine belt set ups are super reliable . I'll be running serpentine belt as an added bonus you get a more modern reliable alternator . Tore the trans off today , more cleaning . Found the code , dm . Also pulled off specific swap parts needed of the motor .

Unless you are adding A/C, you might want to consider keeping the v-belt drive. It is less stress on the crank sprocket.

Yep, I got a lap full of sunflower seed casings on a nice hot day when I forced open the vent on the driver side. I guess the PO never opened them.

I have an AAP box and a 1Z TDI and it's still too much rev. I agree with Andrew, regearing is preferred.

The crank pulley is an easy mod. Get a 1Z or AHU TDI crank sprocket (with the D) and simply file a flat spot anywhere on the crank to that profile.
It needs to be press-fit, so go down just enough where it wants to fit, but doesn't slide on; the crank bolt will press it on.
I did mine at home (with the crank out of the block) with a dremel to get close then a flat file to finish it. Go slow, and check the fit often; if you go too big you'll have to weld it and re-shape.
Make sure you have the free-wheel clutch (TDI) pulley on the alternator, too, that's where all the stress comes from that eats up the AAZ sprocket notch; that alternator has got some momentum in it, and the way the diesel motor decelerates to idle rapidly causes big forces on the sprocket.

I do like the idea of quick turnaround time of putting an AAZ motor in . Especially since mine is an original diesel . Couple reasons I don't want AAZ . Crankshaft gear , the ahu and alh both have d shaft gears . AAZ's have the tooth style that likes to let go and bend your valves . The AAZ I have ideally should be rebuilt , and I'd send the crank out to be modded to the d shaft . So, more money . The ahu I have is crazy low k's . It will need a pump and new tbelt that's about it . Money wise it will cost me a g more to go tdi . I think I don't do it now I'll regret it . Plus I've never owned an mtdi . So I'm looking forward to that . The only thing I like about regular tdi is cruise control comes with it . I'll have to add an old school vw system to have cruise .

What have people done to convert non td oil pans to td ? I saw bricwerks has an adaptor . Anything in north America ?

AAZ vote here, I'm a fan. And being in Canada, it should be a no-brainer, they are everywhere north of the border, and dirt cheap. The AAZ with big pipes, intercooler, and added boost really performs. See my build link below, also check out vwdiesel.net and tdiclub.com for in-depth engine help.

Remove the battery tray. Having the battery in the engine compartment is really hard on it. Here's my most recent solution.

As I just posted in another thread:

Andrew A. Libby wrote:
It is the TDI add-ons like intercooler and VNT turbo that give it the added performance. The AAZ similarly tuned will produce similar power to the 1.9TDIs. However, it will do so while consuming 10-15% more fuel and 10-15% later in the rpms. Because of the later torque of the AAZ and its ability to rev higher, it is comfortable at highway speeds with stock WBX gearing combined with taller tires.

Considering the added cost of regearing the transaxle for a TDI and the added cost of either the wiring of a TDI or purchase of a mechanical TDI pump, it could take you longer than the life of the van to recoup the added cost. The TDI will have higher value on resale.

I was planning on going AAZ. Client came in with a Doka with a 1.9 AAZ . After road test, I really need more than that. I have a super low k AHU TDi missing a pump. I can get a core pump near free. I have an AAZ extra pump around. So, I'm thinking of doing MTDi with a Gilles pump. Anyone on the board use one of his pumps? Happy?

Also looking for sheet metal repair panel for battery tray. It's an original diesel so it's in the back close to the right tail light. I've looked around, I'm just not seeing it available. I guess not a common rust area. Should I make my own panel? Or find a donor piece?

I'd think you would be much more at risk of illness from a chlorine/amonia mix than the Hanta Virus which is still considered rare.
http://www.cdc.gov/hantavirus/

and the CDC PDF file of facts for Hanta virus here: http://www.cdc.gov/hantavirus/pdf/HPS_Brochure.pdf

with the ~8million people in NYC and (2) cases reported, I'll just use disinfectant and caution.. no need for hysteria (IMHO)
