contact dan-tss, he has an ss bolt kit for the exhaust manifolds...

I have them, so I know they do. The problem is I don't know the part number because adam88ss used to sell them in a kit for the Z31 and filed the name/part number off the ends of them. I'm sure if you call ARP with the size and thread pitch they will help you out.

M5-100-1LB for the Short Stud
AM5-900-1B for the Long Stud
AMW-750N for the washer
AMN-12-1 for the nut

Does anyone have that 7 digit part# for those?

I don't understand... these are the ARP part numbers:

AM5-100-1LB - Short Stud (18 needed) - $6.43 each = $115.74
AM5-900-1B - Long Stud (8 needed) - $7.56 each = $60.48
AMW-750N - washer (26 needed) - $.92 each = $23.92
AMN-12-1 - nut (26 needed) - $4.15 Each = $107.90

Total cost = $308.04

Finnish retailers need part no. that are in ARP catalog .

Like 202-6003 for rod bolts.

They say that those are not part numbers. Just names.

It's my understanding that ARP only has part numbers for kits or components for a particular car/applicatiopn. The rod bolts are a kit designed for a particular engine. The main studs are not a kit; it is peiced together from individual items, so those are the individual item numbers they have to order. They will not make a kit, so you won't have a part number to order. You can call ARP to confirm this.

that just means ur not torque'n them hard enough LOL

I still don't see the point of head studs before you even start having gasket failures. But I guess if you want to overbuid everything, that's the way to spend money.

Wicked.. I just got few prices.

(ARP Connecting Rod Bolt Kits)
ARP 202-6003 KK-PULTTISRJ NISS 87.00e -> $110 [in Summit $51.88]

(ARP Main Stud Kits) ->
ARP 202-5402 PINNAPSRJ RUNKOL 149.00e -> $190 [in Summit $89.88]

236.00euros -> $300 [in Summit $141.76]

Cheap eh?

If i order from summit. I pay maybe $200 including shipping (International order pay $24 extra). When they arrive here i pay 4.7% customs for engine parts and %22 for taxes.
That would get me $253. Only $50 difference :roll:

And is someone in usa buys them and sends me cheaper i might same more.. (more eBay reading)

After I bought mine I called ARP and told them that the above said part numbers made up a kit for our Motor, the represenative I spoke to kind of just blew me off.
I just called and got the same thing; a flat "no". Essentially what he explained is there is not enough demand for a kit to be made for our application. They like to engineer each kit to an application, whihc would mean getting the actual engine in question and installing the parts to say something beyone "it fits and holds the head on there". Can't say I blame them, he said they are always willing to sell the bits individually if you ask by part number.

Final part numbers and prices from ARP:

AM5-100-1LB - Short Stud (18 needed) - $6.43 each = $115.74
AM5-900-1B - Long Stud (8 needed) - $7.56 each = $60.48
AMW-750N - washer (26 needed) - $.92 each = $23.92
AMN-12-1 - nut (26 needed) - $4.15 Each = $107.90

Total cost = $308.04

how about just using the long studs? it'd give you the nice studded head ability of laying the gasket on and then sliding the head down into place.

and not be as hard to clean around the next time you have to change gaskets.

not to mention 1/3rd the cost.

Any consensus on whether there's really much benefit in this? Doesn't seem like the clamping force would be improved much overall and isn't there dowels to hold the gasket in place while installing the heads?

any body know how much torque our vg heads needs with arp studs

Thanks

This information is in the turbo faq.

God it must suck repeating yourself 50 million times.

Stock bolts can streach under extream load causing either the head to lift off the deck and eventually burning the gasket out, or the gasket firing ring can distort and just go. The studs are stronger than bolts and prevent that from happening.

well I couldn't find any info on how much torque to give the ARP head studs. Sow I put them at 75 using the ARP assembly lubricant.

Thats a lot. You are supposed to reduce the amount of torque when using different lubricants. The torque specs that are givin are allmost allways while torqing with a dry bolt or stud which you should never do. Allways reduce the torque accordingly with the lube you are using.

Also ARP studs are designed to streatch and the stock bolts are not. Somthing Dweezil forgot to mention but i'm sure he knew.
