Most honda motors (in good shape) will take 10 lbs of boost with the appropriate fuel upgrades. To do 15, some upgrades will usually be required. I have even heard that the b16a2 can take 10 lbs with a stock fuel pump, although I have never tried this to confirm.
I am currently running 9 lbs through an internally stock D16Z6 with no problems at all.. plenty of fuel/ignition upgrades though.

A friend/owner of a local shop that I frequent is running 14 lbs through a stock B18B with a fuel pump, and injectors.

Thanks though... it is VERY important to make sure that whatever motor you run boost through is capable of handling the added pressure and everything. Also remember, Hondas were not designed for turbo, and the internals of the motor are not built with the intent of being used with turbo. For anything extreme, or even not so extreme over a long period of time, low-end strengthening will be required.
