i fabbed my own TB elbow cause i didn't have $100 to blow. it looks good and all, but it's missing that one important function, the threaded hole for the air temp sensor.

do they make bungs that small? where can i get one?

thanks

 

Why not just drill and tap?

 

cause the metal is too thin. it wouldn't really hold it well.

 

drill and tap a piece of 1/4" plate, now you have a bung. Weld it onto the thinner material over a hole.
