Full Race A6

****, I buy a zex kit form a member on here and he doesnt inform me that he doesnt have the tap. It doesnt say anywhere on the manual or on the site which size the tape for the CAI is. Any help with the exact size so I can grab it from work

Thanks

Pretty sure all nitrous nozzles are a 1/8 NPT

Mario.

1/16 NPT straight from the online install guide.

Its not 1/16 have you looked at the thread for the jet?

THIS IS EXACTLY WHAT IT SAYS IN THE MANUAL

<FONT COLOR="red">We've enclosed a tap should you need to mount the nozzle in a metal duct. Just drill a 1/4 (.250)-inch hole where you want to mount the nozzle, then tap the hole and install the nozzle</FONT>

NO TAP FITTING MENTIONED

its a 1/8 npt tap

i'm pretty sure it's 1/8 npt, but if you're not 100%, just bring the nozzle to work and use a thread guage to check it.

How could it possibly be a 1/8 tap? You have to drill a 1/4 inch hole so obviously its bigger than that right? Or am I not getting how its installed right?

But if you drill a 1/4 inch hole, you cant tap it with something 50% of the size

If it's wet, it'll be 1/8. If it's dry, it's 1/16. It says right there, so don't tell me that you checked their website.

It would help if you told us if it was wet or dry in the first place.

If you look in the 'parts list', there is only one tap mentioned. It says it's size right there.

If you can't find it, let me know and I'll circle it and post a pic up.

Thats not my point man. If you drill a 1/4 inch hole which is a LOT BIGGER than a 1/16 tap, how could you possibly tap it? It would drop right through

Also 1/16 is NOTHING, I dunno if you have the kit or not but its bigger than 1/16

Its a dry kit BTW

Mario.

Check the online manual and tell me what it says.

Are you not listenning dude? I quoted the exact line from the Instruction sheet right infront of me, its RED if you cant see it. Thats the exact phrasing when they show how to tap the intake

HOW CAN YOU TAP SOMETHING WITH THE HOLE 4X BIGGER THAN THE TAP

YOU CANT!

Mario.

Dude, I'm just trying to help out. Chill...

Anyways, I had no problems getting my kit installed, I think you are thinking about this way to hard. Just go and do it.

Full Race A6

Um how can I do it if I cant install the nitrous jet.

Just think of the logic of the tap though, makes no sence. Knowone has the tap infront of them?

Mario.

I installed mine just fine, I didn't use a tap. I dunno what to tell ya then.

Bump I got 2mm-12mm from work today

Guess Ill just tap a piece of scrap and fine out which one it is

Thanks anyways

Mario.

Post up information when you do it.

The designation of tap size has nothing to do with the pre-tapped hole size. Below is the correct drill sizes to use:

1. ZEX dry nitrous system nozzle thread size = 1/16-27 NPT = .246 diam. drill (.250 is fine too)

2. ZEX wet nitrous system nozzle thread size = 1/8-27 NPT = .339 diam. drill

That is the honest truth........end of thread...........

I have an NX tap in front of me. Its 1/16th" NPT. It is not however 1/16" in diameter. 1/16th NPT male threads are just over 1/4" in diameter.

Full Race A6

Oh see thats what I didnt get, I didnt no 1/16 taps were actually 1/4 inch lol

mos

Yeah... ' 1/16"NPT ' uses an arbitrary naming convention like AN, JIC, BPST or any other. Their measured size doesn't match the name inch size.
