Bisimoto ran what 11s all motor with a carbed 1.5 . i mean yes its worked but still 1.5 single cam not stroked or anything even pulled into tech and they said it was a 1.5 and it had a stock ignition still but now hes running a sohc accord motor with a adapter plate to use his D SERIES TRANNY!!!! but hey like all of you say it will never happen . ps just use zc exhaust valves and dont bother with port and polish . my opinion will not do enough to make enough of a difference.
