    Can anyone out there tell me what is the most reliable parts to put in the bottom end of the b20z motor?
    Also i have built the head already, all crower parts including crower cams but without any cam gears.

    Depending on your hp goals, most any aftermarket bottom end parts will be sufficient. look for ARP/Eagle. Also continue with crower, companies with reputations like that are usually your best bet. R

    To build the most reliable bottom end, I reccomend having the engine sleeved by Golden Eagle, buying stock (or lower) compression pistons, new rods, bolts and some nice rings for the pistons. With your crower valvetrain, this motor will easily be able to handle high HP. If your still worried, you can look into purchasing a balls-out high HP crankshaft. I wouldn't worry about blueprinting the engine unless you are going for a drag n/a build.

    it depends if he's goin' NA or turbo. if you're goin' turbo, get some 9:1 compression pistons if you're goin' NA... get a new engine.

    the b20 engine blows my nuts for NA. you kinda screwed yourself by alredy buyin' all that shit for the b20 head. you should swap a b16 head on there. but if you're stuck on NA non-vtec. just get some rods and some high ass compression pistons.

    haha, good job. alright, you're set then, just get some crower rods, pistons of your choice (high c/r), rings of your choice and some arp bolts.

    THANKS FOR ALL YOUR HELP LIQUID00METH :D
    Sorry i was not specific about my set up, my full set up right now is the usual bolt-ons and running the apex-i v-tec
    controller
    fuel rail
    AEM regulator
    larger fuel pump
    PO3 ecu
    nology wires
    external coil
    MSD
    B16 oil pump
    B20z bottom end.
    others later.
    What happen was the bottom end on the B20 just went out on me and now i need to find parts to stiff up the bottom end and would like not worry about it giving out on me.
    Since i'm changing the bottom end of this motor i would like to get more HP out of this motor. W/o changing out the crank if i can.
    If anyone else can give more advice on this topic that would be great :D

    I think that there is a list on here of compression ratio's yeilded by different combinations. Just make sure you can still run of pump gas with what you pick. Has the head been milled at all etc...

    Head port/polish but has not been milled
    Does this mean that i should toss the block and get the b18c bottom end?

    No you need to do a lot more research and figure out what you are doing. Spend a week reading through BBS's and searching the net, then come back and ask good questions.
