16g Banjo Bolt Sizes

[Tanro]

Should my banjo bolt sizes be different on my 16g? I just received this turbo from a member here. It seems that the oil feed on the top side of the turbo has a different banjo bolt size than the 14b I had been running.

Anyone know what size the banjo bolt should be for the turbo side oil feed line? I have the correct one for the head side of the oil feed.

12mm.

Should be 12mm x 1.25 on the inlet, although there are some center housings floating around out there with a 12mm x 1.50 thread on the oil inlet. These are normally only on larger (20G) MHI turbos.

I've also seen a couple Greddy 18G's that used a 10mm x 1.25 inlet thread, just like the oil fitting at the head on our cars.

I figured it out. The head I have as an AN Fitting for a ss feed line. But instead of just rtving the the orginal bolt they drilled it and tapped for a much larger bolt. I have fabricated something for the time being, gonna pick up an SS line next week though. The bolt on the old head was much smaller than the one on the turbo, and now they are the same size, I was trying to use the 12mm bolt on the head, but the feed line would not accommodate a 12mm banjo in both ends.
