Jeff, yes it's the 036 injector. Which also leads me to wonder... the injector I pulled out was an 019 from a 73-74 and my injection was suppose to be from a 76'. I have learned it is quite the frankensiened set up. I think I'll get 3 more and see what happens. (IMG:style_emoticons/default/happy11.gif) (IMG:style_emoticons/default/driving.gif)

TriPort injectors are just a different 'valve' technology. Plenty of cars use them.

That's good to know. This might be a good alt for those hard to get 2.0 injectors? I report back on this thread when I get the other 3. But first, I have to get a windshield. Priorities.

Some of the FI beetle guys have been modifying L-Jet style injectors for use in D-jet applications. They dremel off the plastic around the injector inlet, and use a CIS injector seal in place of the lower o-ring. If I were replacing injectors in a stock D-jet system I'd probably stick with the Neihoff, but for MS or other aftermarket EFI it's a pretty appealing option.

QUOTE If I were replacing injectors in a stock D-jet system I'd probably stick with the Neihoff Especially at only $50 bucks per injector. That's about 1/3rd the cost of a new 2.0 injector (if you can find one). |

As I reported at the time, I installed the Niehoff injectors for MB 450 back in September '06. I've been running them for about two years now with zero problems. I got them at PartsAmerica.com for under $50 each brand new. Only mod needed was hose changeover. Donut seals are standard 914. Pic below is passenger side rail after retrofitting with 914 elbow hoses.

Just checked my records. Actually I put the Niehoffs in 3 years ago, and have had zero problems. Photo below is the business end. Also, when I bought my Niehoffs, I got 3 of this type, plus one of the pintle valve style. Apparently, Niehoff was in changeover from the older style to the newer one. PartsAmerica looked in their warehouse and found them mixed, and replaced my one older style injector with the newer one.
 Surfing the web, I found an interesting article in a GM tech manual. I reproduced one page below... Looks like the Niehoff may be a takeoff on the newer GM "Multec" design, as used in their V8 port fuel injection systems and others....  |

This has turned out to be a really great info thread. Very happy it was started, found and now updated with tons of great information.

I may need a 2.0 injector. Partsamerica.com is gone (the two companies split apparently O'Reilly Auto and Advance Auto). I found these at O'Reilly Auto for $51.99.
These appear to be the same ones jk76.914 is using. |

I have used these guys several times. $18 an injector. you must have cores. works great. flow is measured and recorded. I then match sets that flow the same volume.

Those are mine, but like I said, when I received them, three were of the newer ball valve style, and one was like the picture. oreillyauto.com is the new partsamerica.com, same login and password, still has my account info and list of cars...... Next month, I'll give an update as to how the Niehoffs are running. Once I get a few hundred 2009 miles on it. Jim |

Bringing up a long dead thread, but feel it's still relevant.
I am looking to either send my injectors off to have them rebuilt or just get new ones from Rock Auto. I'm considering not rebuilding mine as 2 are in very questionable shape due to rust on the exterior and I only currently have 5 for the 2.0L. I do also have four injectors that were sold to me as being for the 2.0L, but when I checked the numbers, they are actually for the 1.8L (IMG:style_emoticons/default/headbang.gif) The ones from Rock Auto are here: https://www.rockauto.com/en/catalog/porsche...l+injector,6224 Not a bad price at all, but don't know much about this company as far as quality goes. The price for equivalent ones from a MB 450SE are here and almost $20/injector cheaper, but same company: https://www.rockauto.com/en/catalog/mercede...l+injector,6224 Just wanted to get some input since the thread died and no updates were given as to how well the MB injectors did vs. the original 914 ones. FYI: I did a check for the Niehoff ones and can't find them anywhere so guessing they're no longer around? If anyone has any info., please let me know. |

Figure I would post a couple things here for public record
NOTE: I have not personally tried these but they appear to be a possibility for d-jet cars https://www.fiveomotorsport.com/1968-1973-4...ack-squareback/ I do however run these with megasquirt builds wherever I am using the stock intake runners. https://www.fiveomotorsport.com/a280-a380-h...-fuel-injector/ Bolt on and high impedance so no need to add a resistor setup, higher pressure for better atomization and more accurately sized for our needs |

@DRPHIL914
Phil, as does James, I'm using 280cc high-impendance injectors with the Microsquirt 2056 engine: https://www.fiveomotorsport.com/a280-a380-h...-fuel-injector/ 280cc is plenty enough flow for what I'm doing. I don't know how to convert TunerStudio settings to duty cycle, but I do note that they're working fine and even small changes in the map are effective. So I really don't feel like I'm hitting a duty cycle that's making them work too hard. The only thing that makes me go "hmmm" with alternate injectors for D-Jet is that if they are not comparable fuel flows to stock then you're going to be rich or lean. The only alternative you'd have at that point with the stock ECU is to get an adjustable fuel pressure regulator and try to adjust your AFRs with that. Follow that thread I linked above. The guy had his stock injectors flow tested, then compared it to the FJ67 and found them comparable. Greg |

For those using the FJ67 injector, what are you using in place of the regular injector seal?
I tried using some o rings to match the depth of the normal seal but I can feel an air leak around the injector. |
