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.

I just did this with the 52mm throttle body from GoWesty. I think using this product is better then the 2.1L TB from the Vanagon. First off, its bigger at 52mm then 50mm. And second, the swap was WAY easer. You pretty much just use the throttle arm off the 1.8 L-jet TB. And the drilled and tapped holes at the bottom of the GoWesty unit mated perfectly with the Bosch TPS I used for Microsquirt. Simple!

The link above is how I did it.
