running a turbo b20 currently pushing 7 pounds of boost (upping it soon, probably to 10 or 12) and need a new throttle body. probably going with edelbrock since its slightly larger than the stock GSR or ITR and its CA legal. anyone know the difference between the edelbrock throttle bodies? thres one made for ITR and one for GSR, or is the only difference the sensor it comes with? input from anyone who has one would be appreciated. (tried calling them already, the tech on the phone could only tell me 'gsr is for gsr, itr is for itr'...dont think it was an actual tech)

 

the diffrence is the throttle pulley. Where the throttle cable goes on. The gsr pulls from the top (clock wise) and the itr pulls from the bottom (counter clock wise)

 

much appreciated, thanks
