Throttle Body info

Here is some information about TB's.
2003 and 2004 use the same TB. Same electrical plug.
2005 to 2012 also use the same TB as the 03/04 but with a different electrical plug. You can replace the 03/04 plug with the 05 newer plug as the wiring is the same.
Now comes the 2013 and newer. The casting number I'm told is 251.

The Hell Cat TB (BIG) is the same as the 2013 and newer 251 Hemi TB's.

Anyone that has a 2013+ service manual and can post the throttle body pin-out it would be great so we can compare the wiring to the earlier models. Modern Muscle is now offering a 95mm TB just for information.

On my 03 I'm using a 05-12 BBK TB. I just cut the 03 plug off and wired a 05 plug wire for wire. Been using it for about a year. If someone would post up the pin-out for a 13+ we could see if again if it is just a plug change or not. The HellCat is using a 90mm and there are now 95mm TB's available...

What does it do to put a larger TB on the engine? I'm not familiar with how TB's work.

Welcome to the forum...
Fuel injected engines require a way to control and gauge the amount of air being allowed into the engine. Throttle position is calibrated to the fuel injectors pulse width, rpm and manifold pressure as basic tuning inputs. So basically bigger TB, more air, more fuel more power. Custom tuning is required for major changes. Minor changes can be handled by a stock tune to a certain degree...

If you have the 05-12 TB you can run the Hellcat TB with a Casper Electronics adapter. MMX sells them for about 50.00
