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

Great stuff! Thanks for posting pics!

I'm going to try something similar myself along those same lines. I'd like to move away from stock injectors to something high impedence thats also newer than 35 years old.

What injector connectors are you going to use?

I'm using the connectors that go with the inj's., I got the inj. wire harness when I got the inj.

I finally got this done and the motor is torn down. It will be awhile before I get to use them (IMG:style_emoticons/default/mad.gif) I'm real anxious to see how they work (IMG:style_emoticons/default/biggrin.gif)


I'm supprised this went down the board so fast (IMG:style_emoticons/default/dry.gif) I figured more people would be interested. to my knowladge, this is the first ever retro of a non stock inj. utilizing almost all the stock components.

Even though this is for MS users only, this could open up possibility's to other retro fit's.

OH well, this will make the MS guy's happy, we now have a viable alternative to the stock inj's. These are more than readily avail. and cost $40/4, at PP. (IMG:style_emoticons/default/biggrin.gif) (IMG:style_emoticons/default/biggrin.gif) (IMG:style_emoticons/default/biggrin.gif)
