I have a throttle body with " GL " stamped on it. I am unsure what it came off of and am trying to see if it will fit my gsr throttle body. I also have a b16a throttle body so I wanna use the better of the two. I searched, but only found info on the GR throttle body. Thanks in advance

 

nobody?

Do you have a picture of the throttle body?

 

a gsr and b16 throttle body are the same diameter.

 

First gen B16s were slightly smaller than subsequent versions, 58mm vs 60mm.

 

Measure the back side of the throttle body to get the throttle plate dimension. The larger of the two would probably be the better choice.
