Will 1976 Porsche 912E injectors work with 1.8 Ljet injection, on a type IV built to 2056 cu.in. with Raby RS heads and 9550 cam? I also have a 50mm VW Vanagon throttle body that I converted. I am thinking that the 912 engine being a 2.0L with Ljet injection it would add more fuel. Any opinions appreciated. (IMG:style_emoticons/default/confused24.gif)

I've got the same setup, using 912e injectors. They only flow slightly more than the 1.8s.
Very interested in your TB conversion, and if it will allow for a slightly leaner idle, the 9550 seems to be rich at idle, and I've got the bypass screw backed out all the way. |

They actually flow the same. Here is the original Bosch datasheet. https://docs.google.com/file/d/0B7nmo8cXp08...sp=docslist_api You are basing your data on the superseded part numbers. All auto manufacturers regularly supersede parts to decrease the number of items in their replacement parts inventory. The original 912E injector was a different part number from the 1.8L 914 injector. Because of the low volume of production on the 912E, the part number for the injectors was superseded by the 914 injector. It will work fine in most situations in the car. If you look to the aftermarket suppliers, they used the original part numbers for their supply of parts. So the 912E injectors are a different number from the 914. And there are some small structural differences. The 914 injector has a "chimney cap" on the pintle. The 912E injector has a rounded end with no chimney cap. The 912E injectors are the same part number as a Datsun/Nissan 280ZX injector. The 914 is not listed there. It has a different part number. Don't believe me? Then get on any parts site and check. All of the aftermarket suppliers list different part numbers for the 912E injector vs the 914 1.8 injector. |
