24v v6 cosworth BOB/BOA
Discussion
I work on these engines a fair bit BOB is the better unit to get. It's better balanced internally and has hotter cam profiles then the BOA. Downside imo is that BOB has two timing chains, both somewhat weaker then the BOA single chain (which can stretch quite a lot given it's length). My ideal stock engine would be a BOB with BOA timing chain and heads and a better intake manifold. There's some info on my site.
