Does any one know the thread size and pitch that the direct port NOS nozzles use? I want to plug off the manifold where the nozzles were and I need to know what size screws to buy. Thanks

 

i think its 1/8 npt. someone feel free to correct me if im wrong.

 

i was gonna get plugs, but they were a bitch to finsd, i plugged mine up with jb weld. it holds great

 

just jb weld it, its 1/8 plugs. or put screws un there and jb weld. i say just keep the n20

 

1/16 npt plug. Or you can cram any old screw and some jb weld in there if you like the rigged look

 

I haven't actually got the NOS system yet but I plan to get it. While I have the motor apart for rebuild, I want to drill and tap the intake now, so I won't have to pull it off again to do this. I just need to know what size tap to use. Is it 1/8 or 1/16 NPT? Thanks for the info!!

 

i'm right there wrong

 

ohh , the way u asked made it sound like you were trien to find a plug to fill it up. the tap is 1/16, hardware store or summit.
roby

what manifold? i have a cpl one s drilled for dp ...save u the trouble

 

It is a GSR manifold. I have already port matched the intake to the head so I am just going to drill and tap the one I have. It would be more trouble to report another manifold. Thanks though.

 

if the tap is 1/16 then the plug is 1/16 not 1/8

 

duct tape

 

what dont you understand? the fact that i misunderstood his question or the fact that i corrected myself?
