Hello, yes flywheel is cnc machined down to 7kg. This is why i want to do the balancing of the whole assembly with bobweights, because i know that it's out of balance now.
Engine in stock form had dualmas flywheel with over 14kg, than i put on 2.5 singlemass flywheel with 8.4 kg, and lightened it to 7kg. I asked before about balancing but in my country nobody knew what to do. Then i bought Jim's book to learn about v6 balancing.
I intentionally lightened the flywheel at front so that the backside with unbalancing holes remains like it is, so it still has the imbalance. I think that with calculated bobweights and 51% balance factor i should be ok for road/trackday setup?
Here are the pics of bearings after 10.000km (hard road driving and few trackdays) This is the setup like i wrote and not balanced.
Not good, but not so bad either for unbalanced hard driven engine.
I will be thankfull for any advice ofcourse
About the plenum, i was never satisfied with stock one that has just 2.5 litres of capacity. So i went and do my own and because i have acces to a lathe i did proper trumpets inside and even some calculations about intake lenghts (not sure if right but i tried

) And then i got a birthday gift (84mm tb from ferrari/maserati) so it all nicely match up.
I think for a 3.0 engine runing without MAF on check engine light and no remap gtv was quite fast (21 s to 200 kph)
