My invoice from McMaster says $45. They are slightly used, less then a thousand miles. Lets say $35 obo.

I know a lot of turbo guys use metric blues, do you know their boost limits?

**ivprodigy@gmail.com** · 07-11-2013, 08:15 AM

Can these be re-used?
I thought that these are stretch bolts that once torqued, shouldn't be used again

these do not stretch

**325est13psi** · 07-11-2013, 08:22 AM

but there isnt a defined torque, some say 60 some say 70...

im only at ten but tuning is holding me back, read some m20 turbo stickies, some run metrics to 2bar
