Alternative head stud washer solution to ARP's.

What torque is everybody using?



JP said the digging in is due to lack of lube and the washer turning.

That picture is for the 11mm stud used on the stroker engine, don't use that torque value on a 2.2 engine

[Thuppu]

This one uses my washers(ID 12mm, OD 24mm).

Damn that's a big turbo!

[SteveH]

My ARP's have these torque values. I've assumed it's the 'B' option for aluminium.

Thuppu washers FTW!

Well I've inquired about the Toyota washers and they are on order from Japan if you want them in the UK. Two weeks minimum to get them here!

For strokers with 2.5 Block and 12mm studs. 12mm with 25mm OD so may need a bit of machining:

Hey guys

You can also use the washers of the VW T5 2,5 TDi

Part Number : N 901 157 01

Also a good choice

Diameter : 12,5x23x4,5

Seems I was talking bo**ocks with that previous post, ARP just changed the torque spec from 65 to 85ft/lb

BMW washers can be used as well, hardened and grinded. (1112)1265388 fitted on older M20's until the newer IL4's.
