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)
