    bahahahaha

    oh shit, where to begin here...

    first off, you're gonna need a mount kit to put the B16 in the CRX...
    hasport.com is your frind as you will see...

    next, you need a cable to hydro conversion so you can use that tranny in the CRX... available from hasport...

    next, you're gonna need some axles... also available from hasport...

    P28 ecu, is for a sohc, and is OBD1... your shell is OBD0...
    you can either get a OBD0->OBD1 conversion harness and have the P28 chipped to run a B16, or get yourself a PW0, or PR3 ecu, which is the JDM OBD0 B16 vtec computer...

    you also need to worry about the shift linkage, also available from hasport...

    check this link out...
    http://hasport.com/Products/Mount%20Kits/Mount%20EFB2.htm

    thats got the mounts plus all the shit listed above, except the ecu/wiring shit
    hasport does offer some wiring solutions... check into it...

    Is what worth it?? All that money and effort to do the swap? Well that is up to you. It is quit a bit of money but agian its all up to you. If your header is for a D - Series motor I dont think it will fit on a B series.

    I have a b16 crx and I can tell you it is well worth it. I love my crx, the b16 is quite powerful in it. It's a fun car to drive and I wouldn't do a honda any other way :)

    btw - I spent ~$3000 on my swap.

    you'll need 2 O2 sensors. If the header only has 1, you need to have another bung welded onto it to fit the other sensor.
