Proper ITB sizing

Hello,
I have a 99 Miata, and was wondering after looking up various ITB sizes what everyone else's opinion was. I've seen anywhere from 40-50mm. I know people do the gsxr swaps (42mm) and are supposedly fine, but people also put 45-50mm on. Basically looking for a setup that will mean something else other than the intake is holding performance back. Possibly achieving around 150whp. I have a stock engine except for the exintake swap and the stock jdm exhaust header.
If you have power numbers I would be delighted to see them too!
Thanks!
