I am thinking about buying a bigger throttle body for my car? Has anyone here ever install one before? Any change in performance & idle characteristics? How difficult to install?Any comments would be helpful. Thank's.My mods are PFC,Greddy SMIC,Twin Power, Full HKS hyper exhaust system ( no cats), FPR, Bosch pump & Sard pump, Blitz Dual SBC.

 

The intstall would be super easy. Disconnect elbow, throttle cables, throttle body, any hoses and voila. Put the new one back on.

Where are you getting yours? Only one I know of is FEED...

 

Thank's Boost. Either Feed or Knightsports

 

I'm guessing the stock and Greddy elbow's still mate to the larger throttle bodies?

 

Can't RC Engineering bore it out for you?
