I found a very nice throttle body from 2L turbo Nissan. The ID is 2 5/16" . I
wander if it's big enough diameter for my NA 13B,
or I should look for a wider one?

IMHO With your Cosmo 13B Bulent you should look for a bigger one or make one.
What size intake pipes are you using? Add the area of all the pipes and that should
match the area of the throttle body butterfly. No need for a pressure
drop across the TB butterfly with EFI.
