480lbs for the FA20 with transmissions and accessories
433lbs for the BP Miata motor and trans (5 speed)
Our trans is a bit heavier as well.
No idea on the weights on this V6 you speak of.
On the subject of V6's, I said I don't really want to get into it, but if you insist:
- Only 4 mains (VS 7 for an I6 or 5 on an I4)
- Splayed rod journals that are weak
- An inherently imbalanced engine design.
I can go on, but the ONLY thing a V6 has over an I6 is packaging. Over an I4, it's displacement (which if you haven't noticed the OEM's are doing away with V6's and replacing them with turbocharged I4's).
Now, if one had to use a V6, I'd be eyeing a GR motor from Toyota to keep it somewhat in the family. 1GR with a TRD supercharger would be interesting, but 2GR-FSE would be interesting as it has the same injection system as the FA20. Small possibility that the swap could happen without going standalone... I don't really see the advantage in the Honda motors (lots of work for not much more displacement/power)
