your friend dropping a valve isn't because of boosting. you can boost a honda if done right and tuned. it just depends on what your goals are. if you're looking for more power on stock internals the sr20 may be the better choice, but you can have 200-250whp on a stock internal b16. if you're happy with 200-230 on your daily driver and want reliability then boost what you've got. if you want more then build it or keep looking.
