Which ARP part #'s for the manifold to turbo and turbo to O2 housing bolts, studs, etc?

 

Anyone know the correct size Nord Lock washers I need for the stock size exhaust manifold to turbo bolts/studs and for the stock size turbo to O2 housing bolts/studs? I'd like to order them right away. Thanks!

 

Use Stover Lock Nuts and you will never have a problem. Keep in mind they are intended to be installed and hold in place. Therefore, if you have to remove you need to chase the threads with a thread chaser and not a thread cutter. You will also need to use new Stover Lock Nuts.

What size?

 

Interesting solutions.

If you run extended periods on the track you will need to safety wire the bolts... I haven't found anything short of safety wire that keeps them from backing out.

 

i use these and they are AWESOME

yup, thats why Lockwire is used on Aircraft. I've used it on turbo bolts before, worked a treat

 

Can someone PLEASE post the bolt and stud size and thread pitch for the manifold to turbo as well as the turbo to O2 housing.

 

M10 x 1.25 most likely 30 mm for o2 housing and 90mm for turbo to manifold?

 

here's a video on nord locks for those interested.
