hi Andy
in essence you are right the 928 is a big version of a 944, but there is a very big cost difference, 944's can be had for acouple of hundred pounds while the 928 seems to still command thousands, the back end of the 928 is very different to the 944 visually, l think people have suceeded in installing the 928 engine in the 944 buts its a bit of a mission, steering in particular conflicts with the exhaust mainifold on the one side, and l cant imagine bits for a porsche V8 engine are going to be cheap although l dont think they ever wear out,

Ah, ok. I know my mate has got one, but I think I prefer the looks of a 944, there is something about the 928 that just isn't right so I am not sure why the price swings so much between the two

You can get patent parts for the 928 V8, but they still cost (comparatively) a fortune. He is finding it cheaper to buy in the states and get them shipped over including the customs piece on top.
Cool.
Andy
