This may be a long shot. I am just wondering if a drive by wire throttle body from a 5.7 or 6.1 hemi is compatible with the 3.8 and if the bolt pattern is even close. Any Ideas???

 

Also interested in a larger throttlebody. Put one on my 4.7 ram and it gave it like 12 more horsepower. Would be a nice upgrade for the motor.

 

I had a guy do TB boring for the car I had before the Jeep. I think it was around $250 and when you sent in your core you got like $100 refund. The bored TB alone probably won't do a lot unless our current TB's are that in-efficient, but combined with higher flow air intakes it could definitely help.
