Dtronic differences/simularities 914,bus type III
 

Can someone inform me if 1.7 914 throttlebodies/intake manifold runner diameter are smaller than a 2.0 or a 1.8 914s. Are bus type IV engines equipped with the same system as the porsche, how about the type III? Any enlightenment will be appreciated. :)

There may have been some Buses that were fitted with D-jet EFI, but I think the majority of injected Buses were L-jet.

The Type III used a very similar D-jet setup to the 914, but many of the parts were different. The ECU and the MPS were differently calibrated, for one thing.

There were D-jet 411s that used Type IV engines; they were pretty much identical to the 1.7 liter 914 stuff.

I'm not sure exactly what can be interchanged, frankly. That has never been my interest.

Type III d-jet is simular the throttle body is different (smaller), however the electrical board on the throttle body is identical to that of the 1.7 914, just mounted differently I belive the injectors might be interchangable with the 1.7 914 but I am not dead sure on that, as it has been a long while since I researched it, memory fades with time
