It is my experience that you have to cut about 1cm off of the input shaft of
a gasoline T3 transmission to make it work with a VW I4 engine. This, as
you pointed out, makes the input shaft the same length as a Diesel one.
Some of my customers ordered up a T3 Diesel input shaft and installed it on
their T3 gasoline engine.
There is one exception to this rule now... not all I4 engines will work in a
Vanagon. The Audi 1.8T engine from an Automatic will not work as there is
no place to put a pilot bearing - they actually used a different engine for
the manual and automatic engined Audis!

Subject: I4 Transmission Input Shaft Length
As I have indicated in my musings on transmission gearing choices, I am
building a DK transmission with DZ bellhousing for my Turbocharged Audi 3A
2.0L 8V engine project. When I did my current RV engine with DZ trans
(running well, thank you), I discovered to my chagrin that the pilot bearing
fit in the crankshaft, but the length of the diesel input shaft was longer
than the crank recess. I had assumed that this was due to the fact that the
Golf GTi engine had been designed for transverse mounting and that anomalous
transmission/pressure plate/clutch approach. Don't remember the exact amount
that had to be shaved. The work was done by my transmission rebuilder. The
conversation went along the lines of: "Uggh, shaft too long! We cut! Fits!
You pay now! Uggh!" Nothing quantitative here.
I then thought there might be a clue in the VW part numbers. For example,
the
1.6L NA diesel was available in the US as the CS engine (Vanagon Diesel)
(longitudinal mount), the CR (Golf, Jetta, 1.6L NA transverse) and the CY (T
urbo Diesel Quantum and Audi 4000 - longitudinal, and Jetta - transverse).
Well, all 1.6 L diesels, NA and factory Turbo are listed with the same
crankshaft number 068 105 101 M. Likewise all 1.8 L gas I-4 engine use the
same crank (026 105 101 E) whether or not they are mounted transversely. Of
course, the part drawings show the same pilot bearing for all longitudinally
mounted engines (and no such item for the transverse units).
So I don't know if the pilot bearing hole in the crank is the same for the
Vanagon Diesel as it is for the Audi 3A 2.0L engine. Anyone with a diesel or
gas crank to measure depth?
But I do know the quantitative difference in the length of the DK and DZ
transmission input mainshafts. The DK (air cooled with 4.57 final drive) has
an input shaft length of 298 mm. The DZ (diesel, 5.86 final drive) shaft is
287 mm. For a cutting removal length of 11 mm!
Hope this helps someone someday.

I checked Tom's pages. Very helpful but not exactly quantitative. Now the
problem is somewhat unusual in that the
