I was wondering because im getting ready to purchase the rbc intake manifold and kpro this week and i have the extra money. So if the throttle body would make a difference thats worth something then im going to buy it. I also have the password jdm CF intake and i wanted to make sure there wouldn't be any fitment issues.

 

62mm

 

if you get a bigger throttle body then your going to need to get the RBC port matched if you wanna see some gains. personally i wouldent do it save for something thats gonna help your car out more. what other mods do you have?

 

buddy club header, 05-06 type s exhaust, password jdm carbon fiber intake.

 

All K20 TBs are 62mm stock. I bore those to 65mm through with a 70mm tapered opening. I also bore the adapter and port match the manifold opening to 65mm.
PM me if you are interested.

 

Has anyone yet taken the BDL 70mm TB and port matched the RBC IM and adapter to it, for either a turbo or all motor application??
