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. ok mrholland and brant here is the link to the topic where the CARB specification/certification is posted for the 75 and 76 2.0. http://www.914world.com/bbs2/index.php?sho...64241&st=20 and here is the info on how model year cars were defined in terms of which calendar year standards were applied. don't get a headache reading. classic legal gobble de gook you have to read 5 times and think did i just understand that or....... (IMG:style_emoticons/default/confused24.gif) and this is the very strict limitation put on 76 914 CARB certification. the certificates for all the other MY 914s do not have this limitation. sh$t i stumbled across researching entirely unrelated matter of 1.8 L jets. because 74 L jets have weird vague emissions stickers that we recently discovered the USEPA and CARB must have pulled them up on so they had to correct the emissions stickers for the last month of 74 49 state 1.8s. its whacky stuff. classic regulation bureaucracy stuff. they are a slow chasing you but they never give up (has been my experience in life (IMG:style_emoticons/default/biggrin.gif) ) took em all year to catch up with VW on the 74 1.8 914 but they caught em right at the end and made them fix it. since stumbling on this i have worked out at least three cars that sneaked through on this techicality. the 1970 ford falcon. the 1974 VW 412 fastback with manual transmission (49 states) the 1976 914 2.0 (both california and 49 states). although they did not really sneak through. these were end of the line models. no more afterwards. so the USEPA ok'd it. its actually why the falcon model name disappears in the USA. its to satisfy the USEPA that its genuine termination and not a sneak around. the point about a 76 914 is that it isn't the CARB waving around some abstract emissions limits in the air, they are pulling out the certification documents. and those are identical to the 75 model because though it is a 76 it qualified for 75 level emissions. it is not build in a time period that includes Jan 01 of its model year. hilarious. it still obviously gets caught out for smogging exclusion cut off date because CARB are probably setting that trigger as a model year rather than a calendar year. its one of those things that you guys invented for yourselfs. the weird concept of a model year which is aug of the year before to july of year named. we didn't have this down here. model years conformed to calendar years. and i know why. our summer break was in january. natural time to shut down factory to gear up for new model changes. |
