Converting a Vanagon TB for use with 1.8 L-Jet, How I did it Options

[MrKona]

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.

The GoWesty throttle body came like this, some kind of a cheap plastic cam printed from a 3d printer.


To make this work, I bought a 2nd switch, and stacked it on top. Also got rid of the 3d printed cam, and had two new ones made.




Lots of screwing around, but I'm hopeful that this setup will at least work as well as the original if not better. Bigger throttle plate, double sealed ball bearings, and the action is so much smoother than what I had.

Will you be selling pairs of the machined alloy cams? Me likely...

I would just put on the factory throttle switch from the stock throttle body.
