Who knocked the CA? I didn't, I happen to be quite fond of the motor. Just pointed out that you have one is all. :P
As far as KA-T goes, ya its illegal, but its probably easier to restore your KA-T to stock to get past a ref than it would say, a CA18 or a SR20 (you dont have to swap motors provided you kept original manifold, etc etc etc)
When (if ever) GReddy gets a CARB sticker for that Turbo Kit I will probably go back to KA24... anyways good luck with the motor swap, let me know if you need anything, or just tell Chris.
