    I'm finally in a place financially where I can build me dream turbo Honda.

    I have a 91 integra gs.
    This is my plan...

    Block:
    I just got a Darton sleeved B20b block bored to 85mm
    9:1 compression cp pistons
    eagle rods
    ACL race bearings

    Head:
    B18a1 Head that was in the car so I don't need to switch wiring harnesses
    Crower 402T cams
    Supertech Valves, springs, retainers

    Turbo setup:
    T3/T4 turbo
    2.25" piping
    27x7.5x2.5 front mount intercooler
    Tial 38mm wastegate with 16psi spring
    Type RS blow off valve
    electronic boost controller
    and of coarse the oil lines and what not

    Fuel system:
    255LPH Walbro fuel pump
    1000cc RC injectors

    ECU:
    flashed obd0 PR4 ecu set for 30 psi, 2-step at 5000 RPM, rev limiter at 7300 RPM so it won't blow a head if the shifting is late

    Now my question, I know it'll have about 400hp at around 15psi, but at full boost maxing out the T3/T4 at like 30psi, maybe more, how horse power should I expect?
