    Basically this is your list of things to complete the swap.

    Engine
    mounts
    Trans
    Axles (90-93 integra to answer your Q)
    shift linkage
    ECU
    wiring (knock sensor..... I think thats it.. or is it only the b16's that have the knock??? I forget. sorry.)

    Thats what you need.

    Yes the DA integra's have the same spline count and fit right in there with no problems.
    All B-series swaps in EF's use these axles.

    Edit- need to learn to spell...

    Actually, they dont exactly fit, you have to pull out some metal dust rings from inside of the spindal. Then they fit like a champ. And no additional wiring will be needed with a b18a1 in a CRX Si. Just plug in the Acura ECU, plug in the motor, and smile.

    I did exactly the same swap in my crx si.. was pretty painless, and fun when I was finished.

    Take it easy pacha...

    We, at least the most of us, don't mind helping people out, thats what this site is all about.
    However you are correct in saying some should search more. Also people should call Hasport and just talk to them about any questions/concerns you have. Thats what there Technical Staff is there for. Take advantage of it!

    4 posts and your already a moderator?
    haha..

    Sorry to hijack, I have been working on a B18B swap into my '90 crx HF and the only thing I have been worried about is the wiring. I have a PR4 ecu to run it. Is it plug and play? :confused: Thanks for any help...

    that ecu should be plug and play if you convert the engine to obd0

    in the future, make a new thread.
