highest compression ratio on pump gas?
Hi guy's Im helping a buddy with his car and just had a question, its an obdII b18b that snapped a timing belt. Im trying to talk him into an NA ls/vtec, thing is we have a b16 head sitting around that is pretty fucked and needs a mill, so this brings us back to the question at hand what CR would be the safest you would go with 91 gas Would 12.5 be too high for a DD even with the right tune? I know this is HMT so flame suit on for going NA, he has his reasons
