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) |

QUOTE Jake, I know you don't like MS. In your opinion, what are the probs. you have encountered? I don't like experimental things, unless those who are experimenting are in the position to prove them. IMHO MS is too broadly used and has too many bells and whistles that can be configured for too many things- thats never good for the guy like most of you- playing in the garage. QUOTE DO you thing, bacause of the size of Daves motor, it was giving you fits? No. The issues I observed were related to the hardware and all the crap that one must go through to make a harnass, set up parameters on injectors and sensors and all of that. QUOTE I can't see why Daves motor would be different than any other motor. It wasn't and thats why I refuse to sell one of my kits to anyone using MS after the FIVE YEARS of bullshit that MS caused for me, Charles @ LN and Dave himself. Sure the system is cheap, but dave could have bought an M400 Motec for what he spent on time and labor repairing the issues that MS caused. My wallet was about 4K lighter and Charles @ LN spent double that supporting dave's project (when we didn't have to. In fact, the experience that we went through with Dave has mandated huge changes to my 2008 engine kit program. History will not repeat it's self. What does SDS offer that cannot be had on MS? I know the fuel tables are 16x16. Are the sensors different? |
