    k24a2 swap coming soon

    Had a question on the swap, I ordered a bare brand new rbc intake manifold and karcepts adapter. Do i go ahad and use the tsx throttle body? Also will all my stock sensors for the tb/intake set up off he a3 mate up to the rbc/karcepts/tsx tb?

    I am going to swap thermostat housings (gaskets etc..)
    crv side mount
    clutch/flywheel rsx s spec
    innovative mounts
    310cc injectors
    have my exhaust cut to fit header or vice versa
    rbc/karcepts/hondata img

    Have the kpro already, I think this is pretty much it if i remember right from the swap thread that I can no longer find

    Yeah my swap thread is gone, I thought I saved it, but apparently I didn't. If anyone did happen to save it on their hdd please let me know.

    You want to use the a3 tb with karcepts adapter for the rbc. Use the a3 thermostat, with the tsx housing.

    One of the biggest advantages is the torque of this engine, if I compare to when I had the race kit on the a3, I would say this feels just as good in terms of torque.

    If I get a complete swap, is there anything else I need to get? Are the mounts the same? Given that it seems slightly bigger, any issues dropping the K24 in the engiune bay? I figured I would get either the K20A2 or the K24A2. The K20A2 obviously is much easier to drop in but it seems the K24A2 is a better choice.

    really it isn't much more work to put a k24 in the car vs. a k20a2. You will need your A3's knock sensor, and Throttle body. You will need a CRV side mount bracket, and depending on what header you have, you might need to remove your front sway bar, or get an EM2 front sway.
    the motor is 19mm higher and doesn't have any trouble fitting into the bay.

    And last. the K24 isn't a better choice. It is just a different choice. I love my k24.

    do you still need the karcepts adapter if Im going to use the rbb (tsx intake mani) instead of the rbc
    I remember hearing around k20a.org that rbc and rbb pretty much the same in terms of their performance

    EDIT: ok i found out that you do need the karcepts adapter even with the rbb

    Is it necessary to get 310cc injectors if your using kpro? Or is an injector upgrade something that can be done later.

    injectors can be purchased later. All you simply do is make the adjustments and clarify what injector your running in Kpro Manager.

    I see something in this thread I want to clarify. A CRV side mount is NOT needed. What you need is the Side BRACKET.
    Also, you might have to trim a small piece on the radiator support to clear the RBC. Same deal with the hood.

    Other things I see missing in your list that came in handy when I did mine:

    Head Valve Cover gasket kit - (if your powdercoating a VC or installing the K20Z3 upper chain guide)
    K20z3 upper chain guide
    Corsport Tranny bushings
    RBC TB OEM gasket
    PRB TB OEM gasket
    misc. exhaust/intake nuts and bolts (incase you strip any)
    Honda Manual Tranny Fluid
    Honda Type II Coolant
    Honda OEM oil filter
    OIl Seal MT Tranny Case
    Release Fork Setting Spring
    Release Fork Boot
    Oil Seal Chain Case
    Clutch Release Bearing

    I don't remember what we broke... maybe 02EPSI can chime in... but it was a seal on the half shaft.
