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

Yeah, your set up sounds good and yes, my AAR will go! I haven't gone that far with the 914 yet as Im still bitchin with the Quattro. I'm trying to retain the original CIS metering ("locked into full flow") and lines toward the intake manifold while sticking the electronic injectors underneath a hidden fuel rail for the sake of passing the visual inspection at the smog station. It's real PITA but i'm getting there.

Speaking of Bosch plugs, no, they do have the rubber seals inside the plugs and I make sure of that before I plug em in. I like to keep everything "dressed" in German as much as I can and hell, you could fake the whole thing by sticking the MS internals inside the gutted 914 ecu, and leave the POS 914 fuel system components in (by pass it all with fake vacuum lines and wiring for appearance purpose) and the only thing would look a bit out of place, a different fuel rail than the tube ones. That would be fine with me as the whole replacement with MS is a big improvement over the stock ones.

Oh yes, it will be running in line with Innovance A/F metering and CHT set up to be sure of my fuel mapping at different speed setting without ending up or finding some melted puddles of aluminum on the ground!

When I get around to do the 914, I'll holler for help....
