ive just acquired a usdm b16a2 from a 99 si with 60k on it i have plans to build it. these are some noob question but ive done some searchin and didnt get everything completly answered. first off what is the stock compression ratio of the motor. what should i look at doing for pistons that wont burn a hole in my pocket with minimal machine work to bump the compression to around 13..if i do get around 13 is that safe for daily driving on 91 oct...

 

ok i lied...i found a few answers to my question but i still have a few...what is the stock CR on the b16...i'm still open for suggestions on pistons to run 12.5-13 compression without spending huge amounts of cash...
