I sent a message yesterday to the folks at GoWesty (their "campus" is located about 0.5 miles from my house!) to see how their TPS could be adapted to work with our L-Jet system. I'll provide an update as soon as I hear back.

The L-Jet is a throttle switch, not a TPS.

So a TPS fitted to it won't work. You would have to put the original L-Jet switch on it.

I purchased the GoWesty throttle body a few weeks ago, and currently in the process of modifying it to work for our Ljets. I'll post some pics of the progress soon.

I ran the go west TB for a couple years. I had ZPhill reorient it so the operating arm would fit.
It works and looks nice but it’s the long expensive way from point A to B.

It woke up the top end considerably, minor hit to the low end though.


Pay no attention to the throttle return spring. (IMG:style_emoticons/default/huh.gif)

Beautiful! I'm going a slightly different route, but I like it. Did you open up the conic on the plenum, apparently it is bottled necked there at that opening.

I was going to buy a used Vanagon throttle body, but then realized the cost of a used throttle body and then the cost of the rebuild and modification. The GoWesty throttle body use double sealed ball bearings for the throttle shaft, which is an upgrade over the oem bushings. I can be completely wrong, but I view the GoWesty a step up from the Vanagon mod.

The one thing that confuses me is where GoWesty put their vacuum port, it's dead nuts in line of the throttle plate. So would this be manifold vacuum or ported vacuum?

I had to open up the plenum with a tail pipe expander from 45 mm to 50mm. Also the snorkel on the air cleaner box is only 45 mm. Ordered a Vanagon rubber throttle body gasket, part # 025 133 073. The air horn is on ebay, 55mm motor cycle velocity stack, unfortunately from China for $9.99 shipped. Attached Image Attached ImageAttached ImageAttached Image[attachmentid=788

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.

so, if i want to do this, but not "destroy" the original parts (put them away in a box) i need the following?

aircleaner, aircleaner to throttle body duct, throttle body for mod, plenum to modify by opening up. (all of which i need to get in from the states and stockpile).

anything else?

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

It is off a 2.1 vanagon. Part #025133067A

Here is a link to one with the intake for $75.00

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.
