Bolt size?

[S14Dorikin]

My bolts that hold the turbo elbow to the back end of the turbo keep comming loose, I have a Garrett GT2871R, 5 bolts. I want to buy some locking bolts from stage 8 like the nuts I bought for my manifold-to-turbo section.

They need to know the bolt size and thread pitch. He's guessing their either 8mm-1.25x30mm OR 10mm-1.25x30mm...If anyone can verify this I would be appreciative. Thanks.

8mm x 1.25 is it.

Thank you...Just to make sure, Do you know if the length 30mm?

couldnt really say, still have the old ones? measure those and there you go.

With an aftermarket elbow, my bolts were too long by about 3/16ths. Get some high grade(not stage) lock washers.
