From what I heard, the I5 (or S5) induced a heavy vibration into the
syncro-drivetrain.
That�s why VW RSA kept the WBX in the syncros.

And the WBX6 had been a european special factory option since
"small-window-Vanagon"-times, too.
The larger windows appeared in RSA in 1995, not 92.

Even the oettinger brochure said so. The brandnew Vanagon came off the
line without engine and was hauled to oettinger where the engine was
mounted.
