    Any comments on this kasi yung makina ng Revo SR di ba 8 valve SOHC lang ata 1RZ ang engine kya ba sya parang bitin manakbo dhil 8 valve lang to. Yung sa adventure S. Sport is a 16 valve 4g63 SOHC ata naman engine nya.

    advantage of 16v over 8valve engines is that its easier to get air & fuel & exhaust gasses in and out of the cylinders, especially in higher RPM ranges.
