Thread Sizing
Wondering if anyone can quickly answer this for me. my lil earl fitting got fucked up for my turbo so i need to get a replacement. I know the incoming line is 4AN and i need to know the diameter for the part where it screws into the turbo, is it 1/4npt?
*Edit* Its a Garrett T25, its the fitting that goes into the oil pressure side of the turbo.

Re: Thread Sizing (g2_boosted)
If you have a T3, T3/T4 it will be a -4 to 1/8 npt. If you have a T25 or a 14b it will be a -4 to 7/16. If you have an RHB5 or 18g it will be -4 to m10x1.50. There's more, but I probably listed yours already.
