but on my throttle body underneath the stock map sensor, i have a little hole. I think there was a nipple there at some point, but when i got the motor nothing was there. do some throttle bodies just have the little hole and it doesnt go anywhere or does this hole somehow run through the TB and see vac./boost?

TB is off of a 98 gsr bolted up to a jg intake mani. I looked in the parts catalog for a 98 gsr and it does not show a nipple there so im thinking it doesnt lead to anything.

this was the best pic i could find of what i think is the same thing im talking about. He has his BOV running off of it (i appologize for steeling the pic)

I think that guy drilled and tapped a hole in the spot you speak of.

 

so there just a little indent/hole for looks, maybe from production? i wish i had a pic of what im talking about....

 

some throttle bodies have the nipple and some dont. jdm b16 and some integras have them the ones without just have an imprint of the nipple
