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 |

there is more to this too.
there was a rival proposal within Porsche engineering tor the VW beetle replacement. piech won out. i believe h. bott was behind the other one. and guess what. the rival was a front engine inline with a rear transaxle. for a beetle replacement. what does that sound like. 924/928 anyone? in common with both porsche engineering ideas was an absolute refusal to do front engine front wheel drive. piech overcame his porsche rivals with his single minded edict that all cars, yes all cars had to be mid engined. VW settled the argument savagely in 1972. basically said you are all wrong. and..........we are going front wheel drive front engined. and by the way. bye bye. VW does not get a lot of credit for what it was doing in the late 60s and 70s. but it was really pushing it behind the scenes. we all got L jet in cars thanks to VW. no thanks to Porsche. VW did all the testing and proved its reliability in hand with Bosch. and VW got first dibs as a result. GM europe also put their money where their mouths were. the Opel Kadet was #4 to get the system. the rest of the USA battled on with strangled carbs and generally what is known as the maliase set ups until they got on the bandwagon. Australia sat back like it usually does, waited until the american public had finished being used as guinea pigs and then just straight out applied the same regs to car design beginning in the 80s. by then it was japanese licensed versions of L jet on everything that came here. |
