    I want to be able to get 400-450 WHP on my hatch but I dont know what turbo to get yet.....

    I have a b18b1 engine
    darton sleeves
    bored to 85mm
    eagle rods
    wiseco piston 9.8:1
    micro polished n balanced crank
    full race port n polished head
    +1mm oversized intake/exhaust high flow valves
    3 angle valve job
    crower dual springs n retainers
    crower stage 2 turbo cams
    str camgears

    walbro 255lph
    1000cc rc injectors
    aem fuel rail
    aeromotive fpr n high flow fuel filter

    msd6 with external coil
    cold spark plugs
    sk2 intake manifold
    sk2 70mm throttle body
    3bar map sensor
    3in downpipe n 3in full exhaust

    s300 hondata with boost controller upgrade
    o2 AEM wideband
    TIAL 44MM wastegage
    31x12x3 intercooler
    b18c transmission with new LSD
    6puck custom clutch
    ACT xtreme pressure plate
    fidanza 8lbs flywheel
    inline4 crank pulley

    I might be missing some stuff but these is what i can remember so far....

    I was looking at a t4 60trim, 70ar compressor side, .69ar turbine side P trim wheel
    and I was also looking at a T04 60trim, .60ar compressor side, .84ar turbine side P trim wheel....

    what do u guys think? I know my engine can handle 500hp+ but i just need the right turbo...

    if its a straight t4 60 trim, i would imagine that would get your there. a gtr35r would be my choice personally. my turbo i have will get me to 400whp, but i might upgrade to a ram manifold and gt35r when i build my extra block i have. but a 60 trim will work also.

    ^^^ GTR 28-35 any Gt turbo will be more responsive than a T4 60trim. I never liked the compressor maps on T04 60trim but i also boost a D.

    Loose the crank pully and put the oem pully back on it puts the crank way off balance at high rpm...

    i dont think a gt28r would be able to flow enough cfm to produce 400whp, maybe somewhere in the low 300whp.... i was leaning more towards a gt35 or a gt42

    I had my new pulley, my 8lbs flywheel and crank all balanced out with the pistons n rods...
