Hey guys.
I got ARP head studs back in 2010. didnt use them till early 2013.
I just realized something.
I got them from mjmautohaus.com and the part # of kit was 251-4701. and I just found vw 1.9TD specific items on the ARP site, Part # 204-4706.
the confusion is that my kit instructions said 90Nm. the kit instructions online for my kit# says 90 ft-lbs.
and the vw specific kit instructions say 125 ft-lb.
And mine are torqued to 100 ft-lb...
Is that good enough????? should I torque more???
P.S. I am running metal HG with 1.5bar of max boost with gov mod. and fmic.

The new kit is different material so they say and they were torqued higher because of that. The kit you bought is what we used before they came out with the vw kit. No real torque values for the vw application, but most on here go 100ft/lbs to 120ft/lbs. If you don't have a leak at 100 I would leave it alone. At 1.5 bar you could have gotten away with stock head bolts so you should be good.

yeah, if u have no issues i wouldn't worry about it.

Cool. Thanks guys.

maybe the 125 that vw recomends are for original studs... or maybe you are missing the conversion because 90 lb ft equals to 122 NM check if vw says LB FT or NM... but if you followed the studs tighting you are going on the right way because i think original head studs strech more than performance studs... thats why performance studs are better because they hold better the head and save your gasket...

Vw doesn't use studs so there are no manufacturer specs. They use torque to yield bolts which don't have a final torque spec. The ARP studs aren't even remotely similar as far as torque procedures go.
