    1. Punctuation is good
    2. If money is really no object, go for a K24 block with a K20A2 head.

    Yes it will all fit. It's been done before, and I believe HASport has a mount kit to put the K in an EF.

    No I can't give you a full list. Even if I could, that's something you would usually pay someone to do for you. Do some research on the forums.

    I spoke with my older brother and he mentioned something to me that was very intriguing he told me about an eg hatch over here in florida with an h22 with an adapter to fit a gsr tranny and he was running mid 12's with a stock motor and clutch. so now i'm thinking i should do that but while the motor is out of the car, port and polish the head, bigger valves, dual valve springs and retainers, more aggressive cams, and a set of cam gears, and with the block, drop in a block guard, a block girdle, low compression pistons, and high compression piston rings so i can boost it so i can run at least mid elevens on pump 93 gas and 9lbs. of boost, what do you think?

    The H on B transmission has been done. I think you need to do more reading up on exactly what all those mods you just threw out there really are.

    Basically you just put the motor in a big box, toss all the cool stuff in there, and let it cure either out in the sun or at my house. it'll build it right up, but sometimes you don't get your motor back.....

    the weather FTL......

    FYI: you will not be able to block guard a closed deck! :eek:

    H22A4 Block = Open Deck
    H22A block = Closed Deck
    H23A block = Open Deck
    H23A1 block = Closed Deck
    F22 block = Open Deck
    F23 block = Open Deck
    F20B block = Open Deck


    Also if money is not a big deal, You should go with the K-series swap. Change the head, cams, intake and header and you will be putting down at least 250 to the floor. Or turbo the K-Series. it is up to you. do a little research. The k-series mount mount kit will cost you almost a G.
