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

SDS is to be commended for providing a basic harness, but their harness is not a very good solution for the 914s engine bay layout or for long-term serviceability. Plan to spend a significant amount of time/budget on the harness design and fabrication if you want a durable and reliable installation. Think about an optimum 914 engine bay layout, EMI-issues/grounding/shielding, durable connections, and protecting the wires and connections form heat and contamination.

See my sig for linky to my SDS install. I have had no harness issues in a year of auto crossing. I mounted the SDS "brain" in the back trunk, and drilled a hole to run the wires. I ran all the ECU related wires, as well as fuel lines, across the back wall of the engine compartment. The coil pack is mounted on the front wall of the engine area. The plug wires do not cross any of the sensor or injector wires. The wires to the coil pac run along the engine tin on the battery side of the engine room. I sent several diagrams and talked with the guys at SDS several times to lay this out prior to ordering the system, and have been nothing but satisfied with the purchase.

Here is the SDS project link, the one below is for the turbo upgrade.
