Please DO NOT Post In The General Section

From this point on until otherwise briefed, posting in the general section of Performance Tech is prohibited. The only thing to remain here will be the stickies. We would just delete this section, but that would cause unintended results.


The majority of the threads created can appropriately be placed in one of the Performance Tech sub-forums or Technical; and the posting of them here is detrimental to the activity of said forums. If you have any questions about where you need to place your thread PM me or one of the other mods.


For the most part you all have caught on without this post, but there have been a few habitual offenders that forced me to say this.


Everyone will get a couple of warnings from here on out, after that I just start deleting threads.

Again if you have any questions, PM me or one of the other mods.

    Plans for new 93lx build

    Im about to get another Cb7 and going over my options. I know i wanna stay non vtec and all motor. A H23 intake so ill use the F22 head with a A6 camshaft. A bisimoto header and fill exhaust.

    Heres are my two build choices, and im interested in opinions and suggestions. Dont leave me hanging here what would you run with. Ill be running a H22 or H23 transmission.

    possible build options

    F22 block (85.00mm bore)
    F22 head (Milled 0.010)
    H22 crankshaft
    F20b pistons (85.00mm bore)
    F22 rod
    2 layer head gasket


    10.19:1 compression ratio W/ 2058.7 cc

    0.055 piston-to-deck height

    -------------------------------------------------------------------

    F23 block (86.00mm bore)
    F22 head (Milled 0.010)
    F22 crankshaft
    K20 piston (86.00mm bore)
    F22 rod
    3 layer head gasket


    10.55:1 compression ratios W/ 2207.3 cc

    0.010 in piston-to-deck height

    -------------------------------------------------------------------

    F23 block (86.00mm bore)
    F23 crankshaft
    F22 head (milled 0.010)
    K20a3 piston (86.00 mm bore)
    F23 rods
    3 layer head gasket

    11.27:1 compression ratio W/ 22.53.8 cc dis

    -0.010 in piston-to-deck height

    ---------------------------------------------------------------------

    F23 block (86.00mm bpre)
    H22 crankshaft
    F22 head (milled 0.010)
    K20a2 pistons
    H22 rods
    3 layer head gasket

    10.62:1 compression ratio W/ 2107.4 cc dis

    0.035 in piston-to-deck height

    I want good opinions here, im really stoked about a new CB7 to play with.

      -I would not use a h22 crank. I would run as much stroke as you can in whatever block you pick.

      -F23 block has a larger main boar than f22; the cranks wont swap.

      -you should get a good cam, bisimoto level 2 comes to mind. With a stock cam, that header probably won't make good power. The stock cam does not have enough overlap to make good use of the savaging waves that header is going to produce.

      -You are going to need a tune once you do all this. When the time comes, hit me up and Ill hook you up.

      I would go with this combo. It should make some nice tourqe.

        ^^^^^Thanx man, seeing how youre in Greensboro I might have to take you up on that. Ive worked with this chassis before but mostly civics/integras(b's and D's you know) either way thanx.

        Im gonna go with this setup for now just to get it going, maybe K20a3 pistons down the road but this be alright for now.
