    Uh B20B.... no replacement for displacement

    i would feel better about pushing more out of the b18 tho... the b20 has thin sleeves

    We are not talking mad numbers here. ( I love when guys say they want 400whp for a daily driver VTEC + Turbo, ya just go try that in a FWD car around town ;) )

    well arnt you talking about a b18 at 230 whp vs a b20 at 230whp? if thats the case, then the b20 takes the win for reasons mentioned earlier

    more torque in the b20, so go for that one
    230 turboed should be a good goal.

    infact i like it because it was about my goal for my b18b1.
    a medium sized t3 with around 10psi in boost might get you there. i haven't tuned on a dyno yet so i don't know where i am at.

    you may think 230 whp is enough but once you get it your options are going to be limited by the thin cylnder walls. 230 is reasonably easy to get on a ls. also ls block are a dime a dozen so it dont think its worth the extra money for a b20. when you decide to go faster no reason to put forged pistons in a b20 the walls will just not handle the power. b18 no doubt.
