Ah now that is interesting! I have a Gas N Gears lightened/balanced G60 flywheel which would be ace if it can be used here! Not actually offered up any flywheel/clutch combo yet but the gent who made the plate suggested the combo i mentioned before, all i've done is mate up the box to the block. Thanks for the shout on the a6 starter, is it beefier than the a4 effort? As for the spigot bearing, shouldn't be an issue as the 06A blocks do not have one i believe (I'm using an AGU block which is an 06A), afaik only the longitudinal 058 blocks have them!
