    i am thinking about buying a '91 CRXsi. i would like to perform a mini me swap with the d16z6 head on the a6 bottom end. i will need the cylinder head and a z6 ecu(or at least something to control the vtec right? is that all? and could i put zc pistons in it and maybe the intake manifold from the z6 or zc? and somebody told me they have a 91 gsr intake manifold on their d16a6. is this possible? thanks--david

    here's your z6 swap shopping list

    z6 head
    z6 intakemanifold (etc injectors, rail, tb)
    z6 head gasket
    z6 timing belt
    z6 waterpump
    p28 ecu (manual)

    i don't think you can swap zc pistons, same bore... but shit i dunno.... and no there isn't a 91 gsr.

    the ZC pistons do fit ... they up the CR to about 11.5:1 with the D16Y8 head gasket

    hey thanks alot. what HP gains would i get from this if any? and the ecu from the zc is set to kick vtec in at what RPM? would i benefit from an aftermarket vtec controller? thanks--david

    the ZC ECU does not control VTEC ... you want to use a P28 (VTEC @ 4800rpm)... a VTEC controler isnt needed but its probly a good idea

    the mini-me w/y8 head gasket and ZC pistons is said to be good for about 160hp (all builds are different though and your numbers can be higher or lower)

    ummm :blink:

    you want to put a D series VTEC head on a D series non-VTEC block right???
    that IS a mini-me

    there are several ways to do it...
    one of them it to use the D16Y8 head gasket (it is half as thick as the D16Z6 gasket) that will give you an 11.1:1 CR now if you use the ZC pistons you will have 11.5:1 CR and about 160 hp

    and the D16Z6's ECU is a P28
