ARP head studs torque

[xero1]

whats the torque spec when using arp studs? i have a s13 sr20det redtop.

[Gramentz]

It's been over a year, but doesn't it specify in the instruction paper?

[ILikeMy240sx]

same sequence as the stock head bolts (starting from inside to outside)

but go in these torque steps20 40 60 80

Ive torqued mine to 80 numerious times..

i got the head studs with a bloan up sr20det engine, so i don't have any torque specification.

25ft/lb, 50ft/lb, 80ft/lb. make sure you coat the threads with 30w oil before torquing them. you can call arp and ask them. this is what they told me to do on used head studs for redtop s13. please call them though(for your own peace of mind.)

[spider_slayer]

i'd call as well. cause i remember when i got them there were specific specs on a piece of paper in the box

I would not use anything but assembly moly lube for lubricant. I would not trust just regular motor oil.

Get a tube of ARP assembly moly lube.

i called up ARP and they said 70 ft lb on sr20det head studs, is this correct? what does the instructions say that comes with the ARP head studs?

If that is what ARP said to torque them to, then that's good. I don't remember what the instructions say, don't you have them?

[xero1]

no, i don't have any instrucions. i got the studs from a bloan sr20det engine.

The instructions that came with mine said 70 ft-lbs if you use their assembly lube or 85 ft-lbs if you use 30 wt oil.

I torqued mine to 80 using arp lube. I have heard of some people taking it to 85/90 on the last step but i didnt trust it.

I have about 1500 miles on my motor now, i checked the torque on them at 1000 miles everything was still nice and snug.

my arp's came with 25ft/lb, 50ft/lb, 80ft/lb using their lube and 85 if using a 30w as someone stated above.

with my head stud kit it said 105 Ft/Lbs on my tag with ARP Moly lube. That seems Extreamly High. If thats the Case I'm betting I'll need to Helicoil the block.

ARP has recently revisited the torque rating for their studs. Personally, I would take a few minutes to call them and confirm that the torque reading on your instructions is correct.

Also, helicoil headstud holes? Ew.
