Oh it's a small world....

I had a 72 1.7L motor with the following 2.0L components.
Brain
Harness
Dizzy and points
Intake box
Throttle body

The 2.0L injectors were shot so I used the 1.7L injectors and the following 1.7L components.

CHT sensor
Pressure sensor
Plug wires (different than the 2.0L)
Fuel press regulator (same on all D-Jets as far as I know)at 32 psi.

A few things about this setup. Most of it came off a 1.8L parts car (1.8L motors come with L-jets) with a blown motor (seemed like the motor was run without oil by the look of the spun bearings). So I can't tell for sure what year the 2.0L setup was. Near as I can tell from some of the part numbers it was a 74 setup. I always had a problem with a high idle, even after changing all the vac lines, inj seals, and intake boots. I guess this was from the throttle body being too big. I never did a air/fuel ratio test so maybe it was from too lean a mix? Anyway I recomend the D-Jet article on the 914 fans web page, under tech references. I also suggest that after installing this setup to tune it useing a mixture meter of some sort (PP has a tech article on how to make one). The setup gave me about 1000 miles (changed to smaller tires so the odo didn't work) with no problems, even though I didn't really tune it properly.

I did this convertion (hack job) because the 1.7L injection was pretty far gone (mice ate the wires) and I had the 2.0L sitting around. However I would say that the stock 1.7L setup is probably better for a stock motor, unless the motor has bigger jugs and/or bigger vavles. Just remember certain components support ecach other. The pressure sensor and CHT sensor are closely tied together and to the engine. I tried putting a 1.7L pressure sensor on a 75 2.0L (mixed them up) and the car barly ran and smoked badly. I put on the right sensor and it ran fine.
