Pumping out 195 hp from a 1.8L is damn good...108.51 to be exact...
raising it any higher would have significant strain on the engine, and cause a lot of damage to it, if not blowing it.
thats why a b18c5 is not the best engine for Turbocharging, Nitros injections, or high psi supercharging amounts.
the b18c1 (integra GS-R) has lower compression ratios, making it more popular for forced induction, and a popular Civic Swap <img src="http://www.zilvia.net/f/iB_html/non-cgi/emoticons/smile.gif" border="0" valign="absmiddle" alt='

yeh you deff. gotta get new pistons but the good thing is that since theyre factory forged you can boost like 10psi max on stock internals. my friend with the itr got a turbo kit and hes gonna boost 8 on stock internals. even the gsr has high compression 10.0:1 i think is the number or it could be 9.8:1 not quite sure now
