FI retrofit, it's done!!! Options

[toon1]

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

This is exactly what I was contemplating for my T4 build, & I am glad you have chosen to be the "Trailblazer" so to speak.
However, I do need a bit more information or clarification. I cannot follow your customization of the new injectors. adding "O" rings here & changing the tip there is a bit crytic for me & I beg for more clarity.
Also, you indicate 4 injectors are available for $40 at "PP". I do not recognize the store. Please help. Do you have the part number for the injectors?

Nice work! (IMG:style_emoticons/default/beerchug.gif)
I'm interested to see pictures of your wiring harness. Will it be cutom made?

Since the interest is growing , I will post more detailed pics. with regards to tip changing and other ?'s

Grey beard, if you look at some of the pics. you will see how I added an O ring to the new inj.body, above the stock 914 O ring. the new inj. was shorter, overall length than stock and the O ring added above makes up the difference for utilizing the 914 mounting hardware.

there is one pic. with the inj. side by side , the inj. on the left has the stock setup for the Ford escort. I cut that off and replaced it with the stock 914 plastic tip and seal.

PP stands for pick and pull, junk yard

Dominic, I am running MS so the wire harness is made for the MS system. I will use the inj. connectors that came off the escort and wire them into my harness. This is a great setup, the escort connectors fit real good, have seals and snap into place with keeper clips on the sides.

A little more info:


These injectors have a large size O ring on the top, 13.5mm, it was hard to find a drill or mill that would work. 1/2" is too small and 9/16 is too big.

I found a 9/16 end mill that had been resharpened and it was the excact size I needed. That was one of the most difficult parts of the project.
