    mini me for all motor i think would be a good choice.

    oem parts are up to you
    sohc vtec head d16z6 or d16y8
    d16z6 or d16y8 head gasket
    d16z6 timing belt
    piston choice is up to you
    be even harder to just try and build the d15 unless you boost the hell out of it.

    I'd stay NA...
    You can get great power out of a d engine!
    Get some A6 pistons to boost compression, and you'll be were you want.
    (check my link and ask there also)

    A6 pistons are still very good for a compression bump if you don't want to run into the 12s...

    what do the A6 rods look like? Are they beefier than the B8 rods? How about the A6 pistons? What CR will it yield? I'm lookin to build my cuzins D15 but know little to nothing about this engine.

    Jon....
    why are you talking about going NA all of a sudden?
    I thought you were going to turbo that bitch and have a fun ass car to drive around in?
    I say turbo, you will be much happier with it when you are done because there will be more power for your dollar, as long as you are going to be building it anyway and I assume having some tuning done.... just go for it!

    peace

    I don't know the answers to the last slew of questions... but 92- you can still run the A6 pistons without worrying about VTEC. You won't get the same compression increase as the DOHC ZC pistons (smaller dome on the PM6 pistons), but you will still probably get something in the high 10s to low 11s. I'm not sure what the exact number is though.

    high compression, cams, and a little head work goes a long way and can be built fairly cheap. . . i'm very happy with my built NA LS motor
