    Turbo build in progress

    whats up guys its been ahwile since ive gotten on here and updated some things i dont have a personal computer
    as of now i am resourcing parts for a turbo build, my f22 has 150k on it and piston rings are shot.
    I am new to the turbo game, but i do have the skills to do and intall it i would like some guidance on what size turbo to run, and how high i would be able to rev this motor im putting together.
    parts list so far:
    F20b3 block (together with all new oem pistons,waterpump etc.)
    F22a head (on my car now)
    h23 IM with IAB spacers (on car)
    OBX ramhorn style turbo manifold

    Parts list that I plan to buy not in any particular order:
    KZS balance shaft eliminator
    Underdrive pulley
    lightweight flywheel
    typical universal turbo parts
    2.5" charge piping
    3" exhaust piping
    bisi lvl 1.2 turbo cam
    bisi valve springs
    Neptune



    Goal is to take the 2 liter block to high RPMS and have boost while up there, so a slow spooling turbo maybe? 10psi is what Id like to stay at no more no less but i want to know what trim turbo would suffice. i was thinking 57 trim but i need some pro advice from people who KNOW what theyre doing. and if i am going in the right direction

    If you plan on doing all that work... Why cheap out on internals?

      What are you using the car for? And how high do you plan on revving it? That cam can support up to 8k rpms. The crank is pretty much bulletproof. Rods and pistons should be aftermarket.

        Using it for weekend fun/cruiser maybe to drive to work every now and then i live in a small country town.

        I have read on multiple occasions that stock internals will hold fine below 12lb of boost i am not too worried about pistons and rods.

        how high? probably 8000-7800 rev limit

        the block, however, is already put together I bought it that way from the machine shop. F20B3 out of a CD accord with all honda internals pistons bearings etc. its waiting for a head to be put on.

          Is this close to what you are looking for?

          Also you'll want to look on the larger side of the A/R if you are looking for power later in the rpm's

            if your doing bisi springs definitely buy the retainers as well. The stock retainers will fail with the increased seating stress of the springs.

              get the high revs out of your mind on boost/stock internals.

                gotcha thanks for the info guys

                after more research i am not going bisi 1.2 turbo cam instead a delta 272
                looking at a gt30 or gt35 turbo
                not so into revving high i do not want to run into valve float and/or slung rod
                figured out f20b3 stock pistons are 9:1 awesome idk if they are overbored as i did not take this block to the machine shop i bought it from someone who did but doesnt have the info on it

                  There should be a stamp on the face of the piston like ".5" if its overbored.
