    Hey guys,

    Lets pretend I have a b20b4 block and a t3/t4 turbocharger.
    What head should I put on? b18 or b16? Im guessing the b18
    Okay so lets say I have a stock b20b4 with a stock b18 head on it
    and I have a t3/t4 turbocharger on it

    can anyone guess what PSI I can daily drive at? and what Ill get 1/4 mile on that.. its going into a 5th gen civic coupe
    thanks guys.

    you could daily drive at 7psi... you could run 14's maybe high 13's

    Thats not good enough... I need to consistently beat 13.2
    So Im looking at high 12's at worst.

    What needs to be done to pull it?

    the highest boost you would probably want to run is 14psi on stock internals.
    the t3/t4 push a lot of cfm.
    my opinion just spend $800 on rods and pistons...then you could run 18 psi maybe a little more
    je pistons with 8.5:1
    eagle rods
    with 18 psi on a t3/t4 you would probably want to port & polish...
    with that you would beat 13.2 (running at 18)
