Message: <blockquote data-quote="myster_e90" data-source="post: 3727891" data-attributes="member: 78133">i've do some research on VTEC engine for quite awhile,based on my experience on VTEC technology engine,it is true that the big VTEC has bigger VTEC letter then the dohc letter,and vice versa for the small VTEC, it has smaller VTEC later then the dohc.example; dohc VTEC on big VTECDOHC vtec on the small VTEC.and there's one more differences between big and small VTEC,i'm sure you guys are familiar with toyota's vvt-i engine technologies,vvt-i is only variable at the intake valve.unless its a twin vvt-i, then the variable valve timing is on the both camshaft.so the small VTEC is something similar to vvt-i,the VTEC is only on the intake side of camshaft,and the big VTEC works similarly like the twin vvt-i,Big VTEC works on the both of the camshaft,so obviously the small VTEC will produce lesser power and torque then the big VTEC.but most of the mechanical stuff are much all the same.so this is so far my research on VTEC engine,you guy's please correct me if i'm wrong,i'm willing to learn.thank you.</blockquote>
