Message: <blockquote data-quote="jugbugz" data-source="post: 2399243" data-attributes="member: 30892">as what spoon says, above 9000rpm, there is too much vibration and fuel ignition won't be accurate, unless you install a block brace like spoons ek9. Thats how they made 11,000rpm, even so, 9000rpm was still where optimum torque was made and 10000rpm was where max hp was made. Anyway, it's nice to have an engine that can rev so high... :D I like the look on peoples faces when I tell people my EK9 revs till 9100rpm :D If you rev past 9200-9500rpm then valve springs etc etc are needed to be changed(B16B). Toda and Buddy club make very nice cams and valve springs etc. I'm still deciding on which way I should go... 1.6L + cams, V springs, new valves, etc or TODA's 1.8L stroker kit + cams etc. i like the fact of staying in the 1.6L class though but the 1.8L is more torquey. :DHowever some people saying B16B is slow?! Wtf! :hmmmm: probally because they running a pod filter in a hot engine bay in a hot country LOL... or maybe their engines have lost compression due to wear... but anyhow, it's how you tune it. My EK9 comfortabally hits 0-100 in 6secs or less.</blockquote>
