Does anyone have the size/specs of the bolts and studs that hold the turbo to the exhaust manifold? Mine are rather unhappy and I would like to replace them. I assume (bad start) the nuts are of the locknut type; would any of you have part numbers?

Of the bolts that I have removed, I have had lock washers, no lockwashers, but no self locking nuts. Maybe one of our friends with a EPC can give us the proper hardware configuration. If self locking, it would have to be of the deformed type, since inserts would melt or catch fire due to the heat.

Turbo to Manifold hardware:
(17) Screw 79 79 156 x 4
(31) Washer 80 73 108 x 4
(32) Nut 75 19 291 x 4
(30) Gasket 83 66 262 x 1

I have assumed yours is a 16v. 8v may differ. Hope this helps.

Thanks! That will do perfectly! Both of my Saabs, as my profile mentions, are 16V.

Just go to Saab and get a set from them.
Local Saab dealer is the GM dealer. if I am going there I better have the part numbers with me.

There's no reason to use "special Saab bolts". It's not as if they're going into a thread in a casting. It's just a nut and bolt. Should be able to get a pile of 'em for peanuts locally.

Measure the diameter of the thread. IIRC it's about an M10 or M12. Measure the length of the thread.
