ok thanks dodge

Is this a serious question????????????

Dude.......Theres a company called Nissan...and guess what??.You can get head bolts from them....How suprising!!!!!

Who cares if they cost $6 or $7 or $8.

Come on...I'm a tight arse my self but really.....

When you look for your replacement head bolts try and get the ones with "13" embosed on the hex head, I am guessing this refers to the tensil strength of the bolt, to the best of my knowledge cap head bolts have a tensil strength of 12.8.

The bolts with the "13" on them are the GX head bolts, so you would need to specify "1200GX" when you ask. These have a higher tensile rating than non GX ones.
I will post a picture in the photo album of a relevant document, because i haven't mastered the intricasies of posting it here.

The bolts in my A15s have been the 13 ones. They must come standard in the A15.

go to NISMO. Skip going to the junk yard, you should never reuse headbolts.

Why shouldnt head bolts be reused?

even the best head bolts will stretch and over time loose thier strength from repeated retorquing, many newer engines have true stretch bolts, or "torque to yeild bolts" that require replacement after use.
it's always a good idea to just replace them whenever the haed is taken off, it's cheap insurance against a blown head gasket. most dealers can get them for you even if they don't stock them. 6 months ago they cost me about $3.00 (US) each.

but the only time a head bolt will stretch is during the torquing process, so if they fail, just replace them on an as needs basis.

I have never seen a head bolt fail in service!

Had one snap on me a couple of month ago.

Of course it was the last one I was tensioning!
