thread size of greddy type s or rs oulet?
 

i need to recirc my car but i dont want to pay $25 for a recirc pipe for my ebay type rs.

maybe i can find a threaded pipe at hd or plumbing store (what hmt is all about).

anyone know the size and pitch of the thread?

pounded a 1" piece of copper pipe into the flared trumpet piece it came with. IIRC i may have had to sand down the copper a bit, but just used a rubber mallet to pound it in.

And the shitty thing too is the knock offs use a different thread size than the real ones.

I have a knock off rs and I bought the recirc adapter that was for the real ones and it was a much larger thread profile. So, I wasted 25 :(

But when I did for the longest time was just force thread a PVC pipe into my BOV and then sealed it with silicone. Worked for as long as it was like that.
