You changed directions a lot.
There is obviously a lot of info and dialogue missing here.
Do you have links to other threads on other sites you exercised along the way about the ins and outs ?
I've got some questions too ....
Question #1 -- open to all comers in the know.
You said your dial gauge adapter wouldn't fit the TDI pump head.
Can a faktry stock AHU TDI (98 Jetta) Inj Pump be fine tuned/timed with a dial indicator - just needing a different adapter than what we use on IDI ?
As in - set/verify Injection Timing mechanically - versus VagCom.
(and any specs on thread size needed for TDI hole)
Yes, I did change directions a whole bunch of times.. Which I am horribly sorry for. BUT it was needed to fully wrap ones head around how EVERY SINGLE PIECE was to work. lol.
These are some other threads I had with other sites, sadly they too are fragments of my progress.. with many jumps to different directions.
When I get it all buttoned up perhaps I will edit this one, and link the other two to it.

Yes the AHU pump CAN be tuned in the exact fashion as we do on our IDI.. But I see no reason to, as the computer can change all the timing values at any given time by itself. All the parts are there for the gauge to physically follow the plunger in its movement. However upon thinking about it, it almost seems to me that the AHU pumps may be set initially by dial gauge.. and then fine tuned with VagCom, else why would they have the ability to put a gauge in the end of them right?
Now I realize I did change directions WAY TOO MUCH. However where I ended up is fairly simple
. I used a 1.6 pump, a 1.6 transmission and 210mm clutch setup, a vr6 water pump pulley, and a mk1 gas passenger side motor mount so I could retain the AHU pump mount. The front, rear, and driver side mounts are all stock mk1 pieces, gas or diesel.
I have what I believe to be the easiest way to swap a 1.9 1Z/AHU TDI engine in to an mk1 or mk2. Mk2 being even easier, because you could use the mk3 mounts that came on the motor then. So even less work to do.
CRSMP5, I do believe that will be my next endeavor
After I get everything else buttoned up and tidy, I'll be looking in to one for sure. Perhaps if you have literature as to what you have done to yours, ie. build thread or what have you, you could link it in here for future reading?
