    I think his 4G15 is fitted with 1.6 pistons...... otherwise 8.5 seconds is really kind of impossible....But I am unsure, coz 4G15 twin weber can kick ass......:biggrin:

    i wan say is the most important is the clutch set no much slip so more the power is fully transmit to gear box compare to ori cluth set...then engine running stock is for save fuel so the power not fully utilise.. is depend how we understand the engine and how engine work and how to tweek the engine for performance and how for economical all we need is to undestand so we can tune to better porformance ... yas i admit 4g15 engin cant go much power band but abit sure can...4g15is not a powerful engine but for learning sure is a good basic engine.... chear i still on learning

    Vios vs 4g15

    1) Dohc vs SOhc
    2) 16v vs 12v
    3) high compression vs low compression
    4) VVt vs apa pun talak tech
    5) light weight vs heavy weight
    6) 110hp 140Nm vs 80hp 100Nm

    VIos compression ratio is 10.5:1
    4g15 compression ratio only 9.2:1

    this is why you see Vios pickup is to light..
