    Bisimoto level 2 piston to valve clearance

    I've just received my bisimoto stage 2 cam for me f22a6. Straight to the point, most people would recommend to check piston to valve clearance after installing the cam, but I wanted to avoid taking the head off. I don't have a lot of time on my hands and this seems like it gonna be a 4hr job. Have you guys with the 92 accord had any problems with piston to valve clearance with the bisi cam? Should I take the time to check. I though I'd save time by asking others if they have done the same thing and that any valve adjustment was neccessary.
    Thanks a lot. Merry x-mas

    at 8.8 to 1 compression ratio

    -15.60 cc dome

    i doubt you'll hit the piston, even with the most lift possible cam available


    so, no your good to go

      I really don't think that that's good advice. I can design you a piston that has a huge -cc dish and could pile drive those valves at modest lifts/durations.

      The F22A piston valve reliefs are really not that big. I would at the very least do a mock up in the car to see if it's worth pulling the head. Pull the OE cam and pop the valvetrain off an intake valve and an exhaust valve and replace the springs with very light ones that you can move easily by hand. Then assemble the rest of the valve train and install the timing belt. Rotate the crank gently by hand and use your fingers to see how much room is left on the intake and exhaust If at any point you can only move the valves a couple millimeters (or less) before it hits either another valve or a piston then it's probably a good idea to pull the head and clay the engine to verify you have adequate clearance. If you have plenty of clearance then reassemble all the valvetrain and retune and carry on.

      If it were me (and I know it's not) I'd find a way to increase the compression and install a decent header/exhaust on that engine to take advantage of a decent cam instead of just building a piecemeal engine. Assemble all the parts for a one-time, well thought out build and do it all at once.

        It's not the "professional" route, but...

        If your stock valvetrain is not in good condition and inspected for good, then support this mod with Bisimoto upgraded valve springs.

        Assuming your cylinder head has no history of milling, you should be fine for P to V clearance. I know of a few installing this camshaft on stock block.

        Set the camshaft to 0 degrees or if using stock cam gear, set it like a stock timing belt job. Lube cam journals and lube generously with good engine assembly lube. Reassemble, set valve lash to .009" INT/.011" EXH.

        Remove spark plugs, turn engine over slowly by hand and feel for any binding.

        You will need to tune this engine when camshaft installed. Get it done ASAP.

        You should atleast have I/H/E and H23 IM swap with this camshaft. I'd even explore a bored TB. This all should be affordable and worth it. If you have money to burn, then add a ported head as well.

            i would have to agree. lack of compression kills hp.

                Nice, you got a cam. But remember, without a tune that cam is pretty much worthless.
