Need help on bolt sizes.

[panamarojo]

Hey everyone. I have a few bolts and was wondering the sizes. This is a 1g gsx, looking for the stock exhaust manifold bolt that connects the manifold to the head, I have the Nuts just looking for the size on the two bolts that connect into it also.

I am also missing the two bolts that connect the oil line to the turbo, and the nut that connects the exhaust manifold to the O2 housing. I have the 3 bolts that connect it, just missing the one nut that connects it. And what size are the bolts for the radiator fan??

Thanks for the info..

There are no exhaust manifold to head bolts. They are all stud/nut fasteners and, for a 6-bolt, are M8x1.25x28mm

EDIT: The length of 28mm refers to the portion of the stud external to the head. See this thread for more accurate information: http://www.dsmtuners.com/forums/bolt-tech/401691-exhaust-stud-8mm-x-1-25mm-x-xx-what-length.html

From the turbo to oil return line, the bolts are M6x1.0x16mm.

The nut for the O2 housing is an M10x1.25.

The condenser/radiator fan bolts are M6x1.0 and about 12mm long.

Thanks very much 19eclipse90 Hmm who ever owned it must have tapped in a bolt or something cause i took two bolts out I know. I found one and the nut for the manifold fits on it. Ill probably just get the same size should work.

You have a 28mm for the length? is this for the size of the stud?

And are you positive on the length of the fan and oil return from turbo bolts? They seem kinda short. 1st gen eclipse gsx

The 28mm refers to the length of the stud.

I am absolutely positive on the oil return line bolts.

The fan bolts, not so much, which is why I said about 12mm. The two fans use different length bolts, the driver side fan uses shorter bolts than the passenger side. The driver side, however, are definitely 12mm and the next size up is 16mm which sounds right for the passenger's side.
