Flipping Eck! I have told you lot why it was dropped. MARKETING![:^(] Since when have Audi or VW built an enthusiasts car? Not since the NSU TTS! The UR Quattro was the nearest. But that was lacking in application. Heavy coup body with a stupid sloping screen and a stupid sloping rear end. A 90 two door 5 Cyl. Turbo Quattro would have been the ultimate. But, MARKETING wanted a Sportscar (sic)![:^(] And, it was sick! Is sick!
You lot have got it wrong again. Both of the engines. Small block and the other, are Audi engines. They came from Merc. (can't speel Mercedes), with the Audi name. How the hell do you think VW got a water cooled engine?
The Scirocco is another good example of marketing's lack of taste. Why would you want an overweight car, with a sloping front and rear screen, when the better, Mk1 Golf, already existed?
Ooh dear. Mk1 already existed before the Scirocco? Dave, some light research may be in order! As for the engines, I have some new fodder on its way on that topic and I hope you can be on hand to add history! This event could even unite the two main valve factions! Stand by.
Better is debatable daved. Rocco has lower roof . The old pug 205 / 309 debate may rear it's head. Not in this thread though, unless we are allowed a hijack?
Factual shocker Dave! Scirocco then Golf! 1974. "Launched six months before the Golf, in order to resolve any teething troubles before production of the high volume hatchback started" - click
Redeem yourself with a factual low down of the 4 cyl origins. Coming to a thread near you soon! Stand by.

that 25v block looks a LOT with the 2.5TDI block I'm raiding for parts same water pump, oil pump on the crank
Brilliant photos Alan! The use of a steel sump, on all that beautiful alloy block, is interesting. The RR/7A/NM sump is mag alloy, of course. It has a separate side sump, and a plastic, anti-surge, oil baffle. A windage tray was also fitted to some motors, but not on the RR, which baffles me! Baffles, get it? Did the S1 have a steel sump? I guess it would have if only the steel sump was fitted, and homologated, on the alloy KW motors? The dry sump, on the 25V motor below, looks like the 7A unit, just a lot less deep!
gigaz. Are you saying that the 2.5 diesel has the more bulbous water pump housing, and the three bolts for the water outlet pipe, as in the 25V lower picture? Alan. Tell us about the oil pump!
Alan. This is fascinating stuff. I had always understood that the bores on AM blocks were not steel linered? But, used some form of metal sprayed surfacing? Are these wet, or dry, liners? What's the history? From the photos Alan has contributed: It looks like the 25V block is some type of Cast Iron? Could they have used SG? The top of the cylinders, on the 25V, appear to be recessed for Cu Ring seals?
