Well I guess if I get such a disc I could buy any old engine and strip it down and rebuild it but I don't know if that would be a good idea or not lol. I guess best thing to do is get the disc first, have a look through the relevant sections and see how well it sinks in.

Just thinking now, on the subject of engines.... I'll have to buy the engine management stuff separately from the actual engine won't I? Bastids! lol
