Default Bolt size for 14b

Does anybody know the size for the bolts that hold a 14b to the exhaust manifold? I can't find it here, I can't find it on google, I can't find it on DSM Talk, and I can't even post there for 7 days.

I need to order a new set and I would like to order them from mcmaster when I get the fancy lock washers.

If anybody here is a member over there, maybe you could ask for me...

14B/16G TURBO bolt size - DSM Forums

that help?

Oops that is for the turbo to turbo outlet... hmm.

Okay... I found this quote:

"I did end up breaking a turbo bolt when trying to loosen it from the
manifold. Luckily my stock turbo had 4 bolts, and my 14b had a stud
attatched to it. More on this below. Do yourself a favor and buy *4* new
turbo to exhaust manifold bolts as well! You should be able to get these at
Pepboys. The bolt is M10x1.25x80. Even if you don't break them, it is a good
idea to use new ones because they do get very weak over time. It will be
less of a head ache for you when you decide that the 14B is too small and
decide to install a Frank 4. <grin>"

Part # is MD132656

That does help. I think the downpipe bolts are the same as the manifold bolts. I do know that the J-pipe bolts are smaller though.

Call a Mitsubishi dealer with the part number, they could probably tell you.

80mm would be about right. the DSM manifold has the bolt holes going through the top of the manifold.

I have a bag of 50 of them for my 16g but only 25mm. Just enough to make it through mani. flange and fully into turbo flange with a lock washer. But M10x1.25x25mm worked for me.

I ordered a box of 10 in a 30mm length. 80 seemed way long, so I made a random guess based solely on how far my fingers were apart from each other when I imagined my engine bay. I also ordered 5 of those fancy locking washers, and some copper anti-seize.
