Frank, I enjoy but barely understand your posts.

If one was to put a TDI (150ft/lbs or so @ 1900 rpm) into the
vanagon, how does one, in your opinion, go about determining
proper gearing of the transmission. I am mainly interested in a
nice drivable, fuel efficient, Vanagon. The regular WB motors have
generally been "peppy" enough for me, I am not after particularly
fast acceleration or racing from stoplight to stoplight. What do I
miss in overall drivability as I consider mainly 65-70mph road
speed. I seems that to match the TDI motor to the vanagon and to
still go upwards of 70 mph I should consider a five speed. Why is
the diesel less tolerant of high revving than the similar built
gasoline engines? Or, why would I want to drive it over 3500-4000
rpm where both the torque and the hp drop rapidly?

Mostly just curious
