Turbo Oil Feed Line thread pitch

[ipt]

What is the thread pitch of the fitting that goes into the block on the SR20? I have heard that it is a M12x1.25, but all the fittings that I seem to be able to find are only a M12x1.5.

Which one is correct?? Can some one help??

It's probably 1/8"bspt. M12 is a fastener, not pipe thread.

It has got the banjo bolt that goes into the head, I can get adaptors that go from M12x1.5 to -4AN so I can use a Braided SS line to feed the turbo, but I just don't want to get everything and it not work.

I'm pretty sure it's 1.25 pitch. I've heard of people using 1/4NPT to -4AN fittings and cutting them down on a lathe and rethreading them to 12x1.25
