Counter to popular belief I do not stay up late inventing hairbrained questions for you all, although that is tempting sometime given the wealth of knowledge here. As of around 10:30 AM today this will be a real life scenario.
Let’s imagine I have a 2.0l case running 1.8 heads with a single Weber that runs but I want to convert back to FI. Let’s further image that I have both a 1.8 FI set up and a 2.0 FI set up sitting in the shelf. Which FI set up would I be best advised to use on this engine, and for bonus points and adding to the community knowledge here, why? BTW - planning on doing a tech day on this with/for the SoCal mafia once I get a plan together. Given what seems to be a trend back to FI (or at least renewed interest) I think it could be a useful tech day for the community. Thanks! |

I dug out my old paper manuals from the 1980s when I worked for VW in Fort Worth.
914 1.8 PET part number 022906031C Bosch EV1 Fuel Injector pintle nozzle Flow rates @ 41.5 psi / 3 bar 17 lb per hour 178.5 cc per min 2.4 Ohm resistance Bosch # 0280150112 Volkswagen # 022906031C 912E PET part number 92360610900 Bosch EV1 Fuel Injector pintle nozzle Flow rates @ 43.5 psi / 3 bar 19 lb per hour 199.4 cc per min 2.4 Ohm resistance Bosch # 0280150105 Fiat # 6052340 Porsche # 92360610900 Peugeot # 7700582691 Jaguar # EAC3620 Volkswagen # 022906031D The 914 1.8L injector is VW number 022906031C and the 912E injector is VW number 022906031D. What you are seeing is the current listings offered by the dealerships and parts suppliers. It is the standard superseding process that goes on with all car manufactures. The eliminate what they consider "duplicate" inventory to cut replacement parts costs. If you use an original 914 1.8 injector, you don't get the same fuel flow as a 912E injector. If you buy new, you will get the 912E injector even if you want a 914 1.8 injector. The 914 1.8 injector was discontinued. So basically, you and I are both right. The currently available injectors for a 1.8L 914 are the same as a 912E. But it didn't start out that way. |
