Default x16xe what size throttle bodies

I am in process of building a x16xe engine, spec will be ported and polished head, canems ecu, reprofiled cams, exhaust manifold and straight through exhaust.

I am hoping for 170+ bhp, what size ITB's should I use, I have the option of 40, 42 or 45mm.

currently spec should be good for about 180? I don't have much detail on the cams, but reprofiled cams tend to be similar as there isn't too much that can be done.

Only other change I am considering is using 1.8 pistons and crank, should be good for another 10bhp?
