How does throttle body size affect engine size?
Intake port diameter also play’s into the mix.I would contact HPI (Horse Power Inc.). They will get you the right bore size and intake port for your application. This is our experience. The air flow of the heads has a great deal of effect on the size of the throttle body needed for best results as does engine size and type of power required.
How big should a HPI throttle body be?
HPI cuts them in half & fits a manifold to the rear of the fly-by-wire throttle bodies. This is a nice improvement. If you have a good set of heads that flow well wait till you can afford a new throttle body. You’ll be better off. As far as size goes I size them according to their intended purpose.

Is it better to have a bigger throttle injector?
Injector size is approached in a somewhat similar manner to that of selecting a carburetor size; bigger isn’t always better. If too large an injector is selected, you’ll waste fuel and hurt throttle response. Low-impedance injectors are available up to 160 lbs./hr., so don’t simply jump to a bigger injector because it sounds like a good idea.

How big should the throttle body be on a 103?
On a 95 or a 103 this is enough. When you go bigger say 117 or 124 then everything gets bigger as well – cams, heads throttle body. There are a lot of guys that run bigger throttle bodies on small motors & say it runs fine but I don’t agree with that.
