Bigger is not always better.
I did some calculations on the 3S-FE as far as airflow.
Displacement = 122.391 CuIn
Assuming 80% VE (volumetric efficiency) and max rpm of 6,000 the engine would need 170CFM.
To flow 170CFM you need a certain size throttle body. I don't know what size TB you would need to flow 170CFM, but once I find somemore formulas i'm gunna prove to you that bigger is not always better.
Heres the calculator that I used:

Bore = 3.39"
Stroke = 3.39"
