The first gen of the LT had the same engine (1.8 or 2.0 liter, I don't) know, as the Porsche 924 and the Audi 100 [C1].

That these clowns only have noticed the VW-engine in the 924, shows two things:

a) the Porsche 924 contains a wild mixture of parts of the whole VW/Audi-range of the early 70ies. There's stuff included from Passat, Polo, Beetle, Typ 3, Typ 4, Audi 100 and even K 70 (cooling water pot, wipers).

b) they don't know anything about the history. The 924 was originally developed as an Audi. By Porsche engineers, but planned as an Audi. But one more sportive car in the range besides Scirocco and Audi 100 Coupé S was too much, so it was a left-over, which was built by Porsche theirself then.
