    Ariel Atom: Ecotech vs. IVtec

    There are a bunch of options
    2.0 liter supercharged eco techs with 205, 230, 245, 300 hp and the torque varies from 200 to 250, too lazy to write it down.
    Btw this is what you can get in the US

    2.0 Ivtec honda engine 220 hp
    2.0 I vtec honda supercharged 275 hp 300hp
    Now keep in mind that the torque is lower for the honda engine by quite a bit I would guess. Got a nice high redline though.

    Now I have a very similar 2.0 liter ivtec in my integra(rsx)(so I'm biased) which does 210 hp and I'm quite happy with its racing....ness and its reliability.
    But apparantly the ariel atom with the 245hp ecotec clocked 2.8 sec. to sixty I think. pretty sure. This is the same as what it does supposedly with the 300hp ivtec.
    The people doing the car in america also seem to think the ecotec could be more reliable although I'm not sure if they do for sure.
    What engine do you have more confidence in. I'm getting this info. for someone I know. I really would have trouble advising a cobaltss engine over a well loved ivtec engine.

    Re: Ariel Atom: Ecotech vs. IVtec

    Do they change the transmission ratios when they change the motor? The Honda has a much higher redline, so the gearing should be lower to take advantage of this fact. If they give you the same gearing as that used for the Ecotech, then the Ecotech will be faster with the add'l torque...

    Re: Ariel Atom: Ecotech vs. IVtec

    I havent heard anything bad about the ecotech yet? Hasnt really been around long enough to ee if it has long term reliability. Cant go wrong with ivtec, how much faster do you really need it to be? Id have him research the ecotech engine see if its had any problems then see which he wants.

    Re: Ariel Atom: Ecotech vs. IVtec

    I don't have data but i think the honda engine is more reliable and better quality than the Opel/Vauxhall one.
