Has there ever been a reason Porsche/VW speced L-jet injection for the 1.8 engines instead of D-jet like the 1.7 and 2.0 engines used?
Usually when manufactures do this there are financial reasons for the change. Either they have the same engine on other vehicles they produce, or its just cheaper to use whatever part is being used. But Porsche didn't use the T4 motor on other cars at the time. And if it was cheaper, they would have done away with Djet on the 1.7 and 2.0. I don't think VW was using l-let at the time for the bus... but maybe? There has to be a reason that Porsche wanted Ljet on the 1.8. Zach |

@L-Jet914 yeah thats the grey area then the department of motor registration or whatever it is called in your part of the world is exploiting.
its very smudgy. the old 76 2.0 L is called a 76 MY on the CARB but the special sort that were classed by federal statute to be 75MY for emissions and other regulatory standards. in effect the 75 was a 1.5 year car stretching from mid 74 to end of calendar year 75. with only one Jan 01 in its "annual" period. and the last 6 months was called a 76 in the showrooms. but its just a 75 that keeps on going. i reckon it could be argued but you would be having to get higher up a food chain than the front desk. and of course you probably need the assistance of a congress person. i imagine they are all painted with a greenish brush in california. but surely there would be one somewhere in the state of california tarred with a different brush. might be out there in regional areas rather than urban? the 912E is very definitely a 76 MY no grey areas. its production period includes Jan 01 1976 even if they don't physically start making them on that day. and hence why it does not just have the 2.0L D jet as an ongoing engine. they had to strap on the L jet and a smog pump. its the only L jet of that time with the smog pump. not sure if its got EGR. its telling you that they had to give up on D jet for 76. someone in europe owns the original 912E prototype the factory ran around in late 1975 testing the system before production. not sure if that car retains its L jet engine. think they swapped it out before they sold it on in typical porsche fashion. they seemed to be into selling their test vehicles when they were finished with back in those days. i remember reading about the car and its owner a few years back.
