Brake Specific Fuel Consumption

Hi, can someone write an example, please? Honda k20 with minor changes like exhaust, induction, ported head, ported intake manifold, ported exhaust manifold, stock consumption of 0,30lbs/hp/hour knowing that how can I calculate the size of injectors, fuel pump, etc?

And the same question for turbo conversion from n/a k20.

the bottom link is the "easiest" to fill in data - and it directly supports k series engines in its calculations - check them all out tho :)

Thanks
