I've been working on retrofitting newer fuel injectors for the 914. My goal was to find an injector that can utilize as many of the stock parts as possible.
I came up with a inj. off a 96 forn escort 1.8l motor. One comment is needed, this will only work with an aftermarket FI system s these inj. are HIGH inpedence. This setup gives the ability to use higher fuel pressure, 44psi . It has a lower flow rate than the stock inj.. so the pulse widths will be longer and should give a little better idle quality. these are disc style rather than pintle( stock). fuel atomization will be much better giving a cleaner, more efficiant burn. The length of the inj. where shorter than stock so I added an O ring to make up the difference. The plastic tips are different ,I cut them off and put the tip of the stock inj. on the new inj., fit perfect. now the stock tip O ring can be used. the fuel rail was machined to tolerance for the top O ring seal. And I made a bracket to support the fuel rail from vibration and also keeping it from popping off the top of the inj. Here's the setup assembled. enjoy Attached image(s) |

great info! i'm interested in how you're going to mount your trigger wheel for EDIS as I am interested in running MSnEDIS as well (main reason for buying a f.i. 914)....i've got both running on my vw and love it. thanks for the updates The EDIS wheel is already mounted. The wheel needs to be separated from the ford harm. balancer and a disc made to adapt the trigger wheel to the TIV. I used 1/8" alum. I machined a hole in the center within a couple thou. of the crank hub. This gave it a nice, NO SLOP fit. I then machined the outside of the disc so it was perfectly round. The wheel was chucked up next. There is an inner edge (flat spot), I machined an indetation on the flat spot to accept the alum. disc.. I then drilled 4 10/32 holes around the out edge to hold the disc to the wheel. The back of the fan was milled down to make up for the different thickenss of the alum disc vs. the stock washer. I mounted the vr sensor to the fan housing top pass side just fwd of the oil sending unit Jake will have a bolt on disc. avail soon at a great price. |
