There's currently a thread about using L-jet from a 1.8L engine for a 2.0 with discussion about using bigger bore throttle body from a later Vanagon.

I tried it but ran into an issue with the orientation of the flat on the shaft that engages the throttle body switch component used with L-Jet.

Pictures are worth a thousand words, so here goes..

Here's the TPS and a picture of each TB with the plate in the throttle closed position. Original 1.8 L-jet on the right, Vanagon donor TB on the left. Notice the different orientation of the flat on the shafts. The flat engages a corresponding flat on the TPS. The flat on the Vanagon shaft is in the wrong position for the TPS.
