What size throttle bores are you guys running on ITB's for a b sereis?

 

Most common 42-50mm.

 

I'm running (about to be anyway) 42mm 954s.

h22 = 50mm

 

We're running 42mm throttle bodies and are very pleased. If you want more power, look at fuel atomization and air velocity rather than throttle body size. The JGTC NSX's run with a single 41mm throttle body.

 

48mm here.


As for what kendall said about fuel atomization, the guys who are taking up the "DIY ITB's" projects should consider this. It seems everyone is doing it, but stilll keeping the stock injector placement.
