Very simple Turbo housing question???

[hippy]

I have a t3/t4 SCM61 turbo took it of tonight because my exhaust housing (o2) part is loose and some one never put the right size bolts in it. SO my question is are they standard or metric?? And any one know the right size too would be great??? I tried a 1/2" in and it went in not bad but very tight in th hole after a few winds in. Thansk guys!!!

The O2 housing to turbo bolts, right? They're metric..I dunno what size though. Go to Ace Hardware & buy a size M8, M9, & M10 bolt. I'm sure it's one of those sizes...dunno about the thread pitch, though.

I want to say M10x1.25 is your answer, I'm about 80% sure.

M10 x 1.25 x 30mm... be careful how big the cap is though... probably want to find an allen type cap for clearance as regular metric bolts would not fit, at least on my o2 housing.
