Ok, i ordered the Greddy oil adapter kit for my EF (b18b1), and im trying to connect the fitting of the greddy plate to the turbo oil line. The greddy plate is a really random 12.25 thread and the line is 1/4. Ive literally been to about 6 or 7 places and NONE of them have anything that even fits the greddy plate.

Any help would be appreciated

 

why not drill out to the next american size and retap with american thread
