Wot's P85? - never heard of that. I too am interested in a mk2 Sporting or ELX85 engine complete with all electronics incl loom etc as necessary, plus Sporting 6sp box, into mk.1 Cabrio - for nom 45mpg.
Also interested in same engine + box into Uno 70SX - should fly, in a 750kg shell, without going the UT route.
