the setup i plan on having is ganna be. short ram intake, intake manifold of course headers down pipe and so on all the way back i light every day reliable tune on a 50 shot. i just need to figure out what size throttle body would be the best becouse i dont wanna go to big or small thank you!!

 

what size exhaust do you have? what type of headers do you have? what type of intake do you have? Are you going to portmatch the throttle body to the intake? Are you planning on changing out the bump sticks later on? any future head work?

 

70mm

 

 

leave it stock. Unless you have aftermarket cams u wont pick up anything but throttle response.

 

euro r intake manifold modded by rosko to 68mm and a professional products TB ported to 68mm. 70mm makes the walls too thin
