Hi, i have a victor X intake on my B18 but i am struggling to find a suitable thread fitting to use for my brake booster. I want to use one of the larger holes but have no idea what the thread size/pitch is?

Can anyone help?

Thanks!

 

1/4" npt. it should have come with the intake manifold.

 

hi, thanks for the reply, is that for the larger size? This was from a parted out car so i have had to find bungs from all over the place!

 

yes larger is 1/4", smaller ones are 1/8" both npt.

 

thanks man, huge help!
