What size bolts for turbo elbow?

[onecrazyfoo4u]

I just checked, and I'm missing 3 out of the 5 bolts on the turbo elbow --- turbo side. Don't know how that happened, guess they backed out. What size of bolt and pitch and thread and all that stuff are they? Anybody know by chance, I can't find it anywhere. And do you guys use locking washers or any special type of nut to keep them on there? Thanks alot!

its hard to say if locking washers will even help. i think once they get extremely hot, they tend to lose their gripping abilities. ive had the worst luck with these bolts and about 4 of the holes on my turbo need to be retapped.

i know they are 13mm, im guessing the size is M8 and are standard, i think 1.0?

Cool, thanks, I'll try those out. Can anybody else verify this is the correct size? Thanks again!
