whats the best throttle body for the B16? thanks

 

stock

 

anything stock.....type r....s2k....prelude...you wont ever need anything bigger than 62 mmm.....but the s2000 one is smooth 65mm

 

50mm and 4 of them

 

there is no best. it all depends on what you are doing with the car/ engine. for high boost applications, the bigger then better. for n/a, you want something that keeps velocity up... too big will make the car feel very boggy unless you have higher compression, cams, head to match it.
