Not the expert here by no means, but I'm not sure I would ever choose a B20b for a boost motor. Just of how thin the cylinder walls are. And if I did run boost on a B20, it deff wouldn't be no more than 8 to 10lbs of boost. If you want boost, just do a LS/V or LS and if you want a N/A motor and B20 would be a great candiate. I plan to run a B20b block with a GSR head in my DA9. But I'm a N/A type of guy.
