ARP head STUDS

Supra_87_mk3 · 05-17-2007, 04:32 PM

ARP studs. I took mine up to 85 flbs. In 5 settings instead of 3.

have you found any problems with putting so much torque on the block, the fac specs say liek 55 pounds or 65 pounds some thing like that. since you put the new studs in have you had any head gasket problems

well heres the thing.. if you mean me saying they can be torced to 100 you would be wrong for doubting me. i do have alot to learn but this is a Quote from the ARP Staff member that wrote me back when i asked if you could torc them to 100ft pounds

HELLO,

THE RECOMMENDED TORQUE IS 75 FT LBS WITH ARP MOLY LUBE, OR 115 W/ 30 WT
OIL. IF THIS TORQUE IS EXCEDED IT COULD DAMAGE THE STUD AND WILL VOID
ANY WARRENTY WITH THE STUD.

Sorry i didn't read you post in time IHATEHACKS.. you just said that.. but at least that also proves my point that it can be done.. but after reading all of this stuff 80-85ft pound will be just fine for me.

Arp studs and headbolts are the two most popular choices. The problem with the MKIII's head gasket wasn't due to anything wrong with the OEM head bolts or the OEM head gasket... it was the low torque rating. The OEM head gasket can take quite a beating when properly torqued.

I'm running ARP head bolts at 75ft lbs (the OEM head bolts will work fine at this level too, but I'd recommend new ones over reusing the 20 year old ones in your car now).
