Has anyone swapped the stock 3.6 throttle body (73mm) for a hemi throttle body (78mm)?

if so which route did you go? Did you source from a bone yard or did you go through a vendor?

figured it's been brought up before but after searching here and other forums I didn't find anything. The products online come with an adapter harness, spacer and gasket. For 220$+
 
The Viper TB bolted right up and so did the harness plug, the intake is bigger so you need to get a CAI. Then a boot to go from the TB size to the CAI size.
Then you need to do the foot pedal reset to calibrate the TB
Then you should get a tune to take advantage of the bigger TB.

Awesome that's what I was needing to know. I've already picked up a new boot for my CAI pretty sure I can reset the tb with jscan. If not I'll do the foot pedal reset. Tune should be good to go for now untill I get my new tune from the shop that installed the supercharger. Thanks for the quick responses!
