    What are the downfalls to raising compression? I have a d16z6 and was thinking of putting ZC pistons in there. In terms of ease of drving, gas economy, and anything to do with installing and customizing

    having to run higher octane, more chances of detonation.

    Ease of driving = no problem... you just have more power and more torque.

    :lol:

    You have to run higher octane gas, and you have to tune once you get to compression levels like that on the street. You can tune it to run on 91 octane, but I would suggest 93 or higher if you can get it.

    what would be a good ratio to go on without using higher octane? BTW I have a d16z6

    I run 11.5:1 on 91 octane with no problems.

    If you don't want to change the gas you're running, don't bother messing with your engine's internals.

    Im pretty sure that high com. is bad for turbo, but if your doing N/A then its just the gas I think.
