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 |

Progress...
The 1.8 was born AFTER Bosch created and de-bugged the L-jet. The D-Jet was rare enough that I have never had to work on one and I believe that system did not go "World Wide". The L-jet was the recipe that CREATED what we have today. It went worldwide and although I have little Porsche experience, I have SHITLOADS of L-jet experience as Nissan jumped on the L-Jet bandwagon early. If you're not constantly changing, you're stagnating, and the competition will leave you behind... L-jet was the way forward IMO. (IMG:style_emoticons/default/ninja.gif) |

(IMG:style_emoticons/default/ninja.gif) no D jet was world wide techninja. we had it down here. it was on the VW type 3 fastback top of the line model. marketed as the "hot rod" engine. from around about 69 on. pretty rare but basically first car with EFI in aus. hardly any survive. also a lot of the Lancias and Alfa saloons had D jet as an alternative to twin carb set ups. again the D jet was more powerful. but expensive. on top of the line models. a few other things floated around down here with D jet on them. I am pretty sure the big citroen DS also had it. wasn't just the USA and was not about emissions at that stage in other parts of the world. it was more about high tech and power outputs. L jet less so. all the VW models that had L jet in the USA were sold as twin carb versions of same engines down here. i dont think we got the merc D jets down here that came out soon after the VW fastbacks. everything i have ever seen is dual carb set ups or mechanical injection during that era. |
