 This is why I had to go to a . 457 air-cooled Vanagon trans.

The 5.Th reason if I may add in the consideration of final drives is
Drivability, which is a relative term. If you tow or are carrying a large
payload, then a lowered geared trans makes sense.
If you want to cruise at 70 all day @3800 rpm(20 mpg my 82 Westfalia with
195/75/14's) then the air-cooled Vanagon  will do this.
I have driven two 1.8 Vanagon Westfalia conversions recently and they are
SLOW. The first three gears all seem like first. I have a hill nearby which I
can top at 45 in my Westy. The two Westies I drove with the Diesel trans
would only top the hill at thirty-five. But I am sure that If both were
pulling a 2,500 LB trailer payload, the Diesel would win. It is slow, but the
torque challenges gravity better.
In my Westfalia with the 2.0 Golf engine I can get up to 75 mph in third
@4800 rpm.This is the best power gear and it lets you accelerate with ease at
low or high rpm. To do the same with a Diesel trans I will assume that you
need an additional 1000 rpm. That's winding it out, not that it can't take
it, but the 1.8 is not the engine the 2.0 is. I know this from driving the
1.8 for 4 years, and the 2.0 for three.
The 2.0 and a four/speed or five speed . 457 trans is going to suit most
conversionists of the Tiico or scratch persuasion.
A few who are in slow country and drive hilly backroads, dirt roads, will
like the lowered geared Diesel trans.
It would be best if we could have a high/low transfer case.
So I can only speak for my self, and as Frank has explained, there are
virtues to the Diesel trans.
However, around here I was unable to sell mine.
