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 |

So if this was the case:
i suspect that no matter what D jet hit the wall emissions wise by 75. the 76s never met 76 emissions standards and certification. were sold as 76 model year but under the certification regime were classed as 75s if manufacture ceased by end of calendar year 1975 - which they did. Why are 76 914s subject to smog testing in CA? I mean, they should only have to meet the 1975 standards which is no smogging. |

I mean, they should only have to meet the 1975 standards which is no smogging. yes this was gone over in another thread. apparently some time back in the past (like 20 years ago?) some owners of 76s did manage to get their 76s exempted. on that very basis. i you could probably do it now too, but its a fight with a dumb bureaucracy. so good luck. you would be fighting the technicality that though the 76 was certified on the basis that it complied with 75 emissions standards (legal under definition of when emissions standards apply per calendar year) they are also technically 76 MY cars. a classic grey area that bureaucrats can see one way or the other way. i could try and dig up the topic and thread with a search when i get a bit of time. its got the documents in it that define what standards were applied and when. the 1970&1/2 ford mustang is another example of it. rather than ford trying to make that mustang comply with 1970 epa standards that came in on the 1st of jan 1970 they stopped production on the last day of 1969. still sold it as a 1970 MY car and it was an update of the 1968 model year car. ------- i'm guessing the way california looks at it is - the 76 is a 76 MY car and thats where they define the limit for smog test compliance on historic cars. and when it does it smog testing it must still comply with the standards it was built with. those standards are on the CARB certification on their records and files. which are 1975 standards. i have all the CARB docs for all the 914 MY years. |
