I believe that the TB for the 912E is identical to that of the 2.0 liter 914.

What about a mounting plate that picks up the TB mounting holes and has holes that match the orientation needed for the TPS?

I did this for Betty's car. I don't know if it really helped., but It makes a difference on the "butt dyno".

Easy to do too. Just about an hour to do all the work. And I fixed it so that there are two screws holding the throttle switch assembly to the body. One is inside, and one on the outside.

Clay, DiD you use the 1.8 TPS on the Vanagon TB ?

I used the 1.8L TPS (It is actually just a throttle switch). One of the screw holes matches up exactly, the other ends up inside the cover. I just made a pin out of a screw, and mounted the throttle switch with the one screw. The point on the pin marked the back of the metal where the other screw goes. So I used the drill press to carefully drill a small hole in the backing plate, and I was able to attach the throttle switch with two screws.

There are some visible external differences. The idle screw is recessed, and there are some ribs on the outside of the Vanagon throttle body. But with how far down it is buried in the engine compartment, it is really not visible.

Makes sense; did you use the Vanagon TB shaft and file the end or did you use the 1.8 B shaft ( as shown in this thread )

Thanks, i'm ready to start in on this....

How about trying one from an Alfa spider from 1982 and onwards. L-jet too and 140 hp.
I have not yet, but will when the next Alfa comes in the shop.

Just installed the modified vanagon TB; sent the TB and a TPS to Zphil in New Mexico. He did a total rebuild and it looks like new. The difference in noticeable; we just did a top end rebuild with 96mm P & Cs.
A few pics sent by Phil during rebuild.

Jim, what did you find to feel different? How was the idle?

Looks like very nice work. (IMG:style_emoticons/default/beerchug.gif)

More power! Complements the larger P & C
Idle is fine

One problem this am: the angle of the TB accelerator arm is another 10 degrees back making it had to acetate smoothly. Going to contact Mr Kona

The 1.8 plenum is only 45mm. The throttle body is 50mm. I used a tail pipe expander and opened the plenum to 51mm.

I just used a dremel with a sanding disk to open it up.

Not to get to far off topic, but... would a Vanagon TB be an upgrade for a 2.0 D-jet set up?

Thanks,
Konrad

Nope. It won't fit. Different mounting surface.
