I suppose that you would use non-egas 3.4L ECU programming. Would that be "close enough" for a 3.2L? I dunno. I don't know if the VarioRam on/off parameters are similar for a 3.2L vs a 3.4L with its longer intake runners and greater displacement.
You might have a problem with using a 2003-04 3.2L engine, though. If I understand the situation correctly, the 2003-04 engines use a cam phaser sprocket system to vary cam timing instead of the "variable chain tension" system used on the 1997-2002 Boxsters. I would be very surprised if the control strategy was compatible between the two systems. I suspect that a 2000-02 3.2L engine would be easier to adapt to your car if you want to retain the non-egas ECU.
Of course, you'd really be set if you could find an affordable non-egas 3.4L engine...
