If you want a replacement diff for your 4k trans (or any other trans parts) I can send you the one I just pulled out for my torsen->locker science project. I'm planning to clean out the garage this weekend so LMK before I send it to the scrap bin.

I'm never above spares! Let me know what you need from me.

I did some calculations with the 5000q Avant gear ratios, it won't actually be bad at all, top speed @ 3700 RPMs in 5th is about 95 MPH, cruising at about 3000 (average 5th gear cruise for most TDIs) is 77-79 MPH.

With a simple 5th gear swap to 0.60 from a Porsche 016, that would drop down significantly to 94.4 MPH at 3000 RPM, cruising at 63 at 2000 RPM.

Engines should be arriving Saturday or Sunday!

Also found out the Coupe GT transmission I have as a spare has a really tall 5th gear, which will be perfect for my 016 for the TD.

Engines are here, I have enough parts for 3, sans injection pumps and timing belts, but easily resolved.

A lot has happened in the last few months:

- Audi 90 Quattro Turbodiesel is basically complete, we are hunting for a 2.7T transmission for improved gearing
- I've got enough Bosch VE knowledge now to Frankenstein Injection Pumps together, and successfully built, tested, and tuned a Turbo VE Pump out of a NA Pump
- The MC1 was removed from the 5000q Avant, and the 2.4D is installed and running.

Enjoy some photos:
