m20 arp studs

[TS87325IS]

Yep thats the nuts, also you would go with the 175 mm long studs i belive 150 is too short, there would be none sticking past the head.

The nuts cost more than the studs lol, i will try them robert. Im not scared.

Honestly, I bet its the exact same hardware.

EDIT: For reference the part # for the nut on McMaster Carr is 91005A037

Total cost on McMaster Carr is $82.74 for studs and nuts.

Closest thing is Black-Oxide M10x1.5 150mm Length Spacer Stud. McMaster-Carr Part # 93275A046 = $2.79/ea

EDIT: Hmmm.. looks like ARP head studs are also Black-Oxide steel.. if these work then lots of people have been getting butt raped @ $225 a pop.

My old metric blues held up pretty well for the past 3-4 years, but i do recommend to buy new ones if you have to pull the head, i belive mine were fine the first two times but not the third, just pisses me off because i allready had 5 torqed down .. lol

Maybe you were part of the 0.02% percent failure rate. I plan on switching to ARPs next time i pop a head gasket mainly for ease of installation. I plan on going through a lot of head gaskets in the next 6 months.

That one probably didnt even make it to about 50ft lbs. It just snapped off. Oh well, live and learn.

[einstein57]

Thats because some people think its a god idea to torque them down to 80lbs. I never go above 65lbs on metric blues. I've had good luck up to 18psi.

[TS87325IS]

of course, but metric blues are super cheap and generally do the job.

Until one breaks off in the block....never again for me ;-)

Yeah we know where to purchase them. People want the actual part # for the bolt itself from ARP.

From what I heard, they are generic, cut to size, and marketed up for m20 builds.

[Cyrix2k]

I think your misunderstanding, metric blues do an decent job, but are not anywhere near the clamping force of studs.
