long story short,
bought arp head studs for my ca18det,
but there is no instruction how to torque these.

there must be some guys out there who know this stuff

how much tourque should be used to screw in the bolts in the block and how much to screw down the nuts (cylindrhead), maybe stock????

there come a tube of "screw-locking" with it, should it be used on both ends of the bolts or just on one?

i looked on the arp homepage,(maybe its my fault) but didnt found anything

thanks

black brandon, dvd david, or jap chris (local norcal guys) all own ca18s and should know. david rebuilt his ca and jap chris took his apart to install cams and turbo upgrade. wait to see if they can chime in.

Call ARP

fsm is ur best friend.

yea check out the fsm and try calling ARP

Call ARP.

For an SR20 you hand screw in the studs (Put on the moly lubricant first) AFTER you put on the head. Then coat the nut, washer, and top of the studs with the moly lube. Torque down the nuts to I belive 65 lbs/ft. (don't quote me on that number. I just know it's NOT the same as the specs found in the FSM).

Anyway, that's the procedure for studs on an SR20, call ARP, to make sure what it is for a CA.

bleachcola · 09-12-2006, 01:43 AM

are they brand new?

95zilvia · 09-12-2006, 01:48 AM

yeah for my SR i torqued them to 65.

TipStylez · 09-12-2006, 02:03 AM

Is it true that for these studs, they are only ment to be torque down once. If you untorque them they are noo good anymore?

95zilvia · 09-13-2006, 02:36 AM

bolts
no, they stretch.

thanks for your info,
at least i contacted arp

screw the studs in the block "hand thight only"
the tourque for the nuts are 70ft lbs, but with a aluminium cylinderhead (more heat expansion than steel) it should be reduced to 65ft lbs.
you must use the arp moly lube on both threads, nuts and washers.

looks like the same as an sr20

thanks for your help

isnt the CA made of iron so you would stick with 70 ft/lbs?
