"Off-hand, maybe not. It's the transmission and the engine rotation, I
would say.

In the 914, the engine is in front of the transmission. In the
Volkswagen, the engine is behind the transmission.

Simplistically speaking, although the 914 engine is based on the Type IV
motor, it is different motor.

Ergo, from a Porsche magazine where a racer used a 930 transmission, but
because the 914 engine is in front of the transmission, he had to invert
it to get it to work."

Months ago, I'd suggested considering flipping (inverting) Audi/VW FWD
transmissions to give a wider transmission selection for Vanagon repowering
projects.  This approach seems especially compelling for those considering
installing high torque TDI motors, since these motors make so much more low-end
torque at 2,000 rpm than waterboxers.  For instance, a 2.1 liter waterboxer
makes about 90 hp at 5,600 rpm, whereas a stock 140 hp. 5 cylinder Audi TDI
diesel makes 96 hp. at 2,000 rpm, or if you install the 173 hp. aftermarket
chip, 112 hp. at 2000 rpm.  (If you want a copy of the chart showing these TDI
values, e-mail me at my new e-mail address, LvLearn@cwix.com, and I'll forward
a copy to you.)

Does anyone know if a Porsche 930 turbo trans could fit in a Vanagon?  They
were 2 WD, had limited slip, and probably had better torque ratings and taller
gear ratios.  Would this be a suitable Vanagon match for a strong TDI diesel
without going to a flipped FWD trans?  Could some factory starter/ring gear fit
this to one of the inline Audi/VW motors?  Besides the 930 Porsche trans, what
other non Vanagon parts would be needed?  Anyone have ratio or torque
specifications for these old Porsche transmissions?

Thanks for your insights,
John

An ME student pal once said,
"Trans troubles go up by the square of over-stock torque loading."
Who said VWs are in no ways like Harleys?
