Hey guys, I am trying to put in a turbo kit. My question is, where can i find a tap that is the correct size.

I am using a 1/2 inch npt to 5/8 heater hose barb. Now i have looked at half inch taps and they all seem so very tiny compared. I am thinking that the inside diameter of my fitting is 1/2 inch, so what is the outer diameter? I can't seem to find a tap over half inch...

Anyone have any pics of the process of tapping the pan.

Thanks. Any help would be nice, I don't know much about this stuff.

 

You will need a 1/2" NPT tap, not a regular tap... The thread is taper to get proper seal. 1/2" npt fitting is arround 3/4" outside diameter.

Go on http://www.mcmaster.com/ and look on page 3. You will get some information about NPT (National Pipe Taper). You can order tap on this site if you want.

 

Check in with plumbing supply stores or locally owned hardware (not "home improvement") stores. Places like Lowes/Home Depot likely won't have it.

 

So i need a 3/4 npt tap? or will the 1/2 inch tap be what i need. The outside diameter is larger. I will likely have to order online but i need to know what i need. I am not sure on the outside diameter of this sumbish

 

You don't have to order it, we got it from Ace Hardware. If you don't need it by today I can check to see what the exact sizes and stuff were. Ours fits perfect with no leaks. Heres a pic of it tapped:

 

Yeah if u could check the size of it, i'd be grateful. Still have the tap? ill buy it off you

I am doing the install this wednesday i think

I am suprised you tapped ur pan on the deep side, i hope you dont have issues!!!

 

Here's a set I bought from Harbor Freight tools. That's a great tool store if you've never been to one. Check them out online and you can find out if there's one near you.

 

This man speaks the truth. I completely forgot that HF might have it. That place is a toy store and will surely have it.

 

Yeah that's where someone else said to go but we couldn't find one here.

 

I shall be scowering there site.

Speed corps. What size was ur hole?
