What are the specs for the stock head bolts to use when torqueing the head to the block after doing the head gasket? I was going to buy an ARP head stud kit but was told it would take 3 months to get to me. Anybody know where i can get new stock head bolts?

What should I ask for? the bolts from an NA Sentra SR20DE? I am going to do the head next week and want to have all the goodies here. How much do new stock head bolts cost?

well if you want aftermarket studs you can get a set of arp head studs for a 1.8 non vtec integra motor... motor code is B18A1 and the arp product number is 208-4302...

i got a price form my local shop for 145 for these.. i cant imagine the dealership charging that much less...

again this is to fit a sr20det redtop head

I went to the store to get ARP, they had none in stock, ARP has none in stock, and they told me 8 to 12 weeks to get one to me. They have to make them, so stockers it is.

did you ask for arp's for a sr20det or for the integra motor i just mentioned... i just went last week to my shop and they told me they could have them in 3 days... im sure you can find some on the internet somewhere without a wait

Integra B18A Non VTEC was what i asked for. They had none in stock in any of their stores, they called ARP and ARP has nothing. Unless the store you bought them from is having them transfered from another one of their stores. The chick at ARP said they would have the supplies to make the kit in about 3 or 4 weeks, another 2 weeks to have them made and then more time for delivery. So I just said man oh man, just buy stock head bolts lol.

So has anyone figured out why ARP sells the headstuds for an SR20DET for ~$300 and the exact same studs (apparantly) for a Integra for about half the price??? Has anyone questioned ARP directly about this? Or is there maybe a difference in the studs for the different cars? I can't see why they'd charge more for one set and less for another unless the grade is different or something. Im a little skeptical about this because I've seen so many myth's floating around here that turn out to be incorrect (like greddy SR oil pan's not fitting on an S14 chasis)...

Can't find the link right now, but it was proven earlier by 1bad180sx that the studs for the Integra are, in fact, too short. Do NOT get them.

Ok then. No ARP. Then when I go to get new stock Head bolts which do I need and how much are they going to cost? Can I simply go into nissan and ask for the head bolts from a NA Se-R SR20DE? Good thing i read the head bolts wont work now, would be big waiste of money.

Yes, just get headbolts from an SR20DE. If you want to be definite, just say a 1992 Sentra SE-R or something like that.

How much are they likely to cost? I cant see nissan letting them go for cheap, that would against their entire business practice...

Not sure how much they are but you should order them from Courtesy Nissan... they'll give you 25% off if you tell them your on the internet and want the internet discount. They give this 25% off to practically every Nissan internet group... 300ZX's, Maxima's, SE-R's, X-terra's, 240's, etc.

www.courtesyparts.com (http://www.courtesyparts.com) is the website, you can get their number from there.

Please find that link, as I am skeptical about it being "proven" ... what gets me is I did not come across any bad fitment issues. They were NOT too short.

Proof would be nice before telling people to not get them. Not saying you are wrong, but I don't recall such a thread debunking the studs that ARP sold me.

I don't understand why ARP is charging so much for them? I remember paying only $120 or so for the correct part number, including washers and fasteners. Get back to me on this, I'll try to locate and scan my invoice.

What is the part number for the SR20DET ARP kit then? What is the difference between the two?

I checked the Freshalloy archives to quote what I got directly from my invoice back in the day...

I ordered my headstuds from ARP direct and they charged me $125.24 (shipping included).
Part number is ATP7.100LU and the item is an 'ACURA B18A1 Short Stud 1.5' costing $11.05 each. Add in $2.11 for the 12pt nuts and $1.04 for the washers.
Stud specs: M11, 7.1" length, 1.5 thread pitch.

here's the original thread (http://forums.freshalloy.com/ubbthreads/showflat.php?Cat=&amp;Board=UBB9&amp;Number=138460&amp;Forum=U BB9&amp;Words=primeral&amp;Match=Username&amp;Searchpage=4&amp;Lim it=25&amp;Old=allposts&amp;Main=138456&amp;Search=true#Post138 460)

I hope this helps, dude

funny thing is that 1bad180sx got his studs from mckinney for a "good deal" tho...

I think after all this i'll just use oem head bolts. No point in taking any risk. I know there are some pro's to using the arp kit, but oem will suffice. Not like i'm going to be running 500rwhp lol.

I have the ARP headstuds in my SR right now (redtop) with no problems. they are the ones for the B18A. I checked 'em 10 ways 'till sunday sunday before i installed them and they are on there with no problems.

ARP's TQ spec seems a little low however. I know of quite a few Honda engien builders that are torqueing the ARP studs to near 80 lb-ft.

oh well..whatever.

If you still have trouble finding the ARP SR studs let me know. We have some.

Ken,

How much are you guys selling them for? I can get them from a company in town for $168 CDN. If you can give me a half decent price on them I will take them from you. I will probably be getting you guys to do my ecu come december anyways so why not do it all at once right.

Is there any issues with them being short?

But nobody has directly questioned ARP about B18A headstuds vs. sr20det headstuds? There has to be a difference...

cdn_w_sr20
10-28-2002, 08:55 PM
I think asad said somebody called ARP and ARP said that those were the ones to use. I don't think there is an "sr20det" kit. Just the B18A.

I had my machine shop measure the hole depth and thread depth of the block, and I personally called ARP, spoke with one of their techs, and gave them the specs that I needed.

They cross referenced my specs with an equivalent bolt which happened to be the same as a particular Honda's motor. Why is everyone so skeptical when I have photo evidence? If it's beyond comprehension, it's ok to have stock head bolts... really it is...

Thanks for straitening this mess out. The reason I want to get ARP head bolts isn't necessarily because they are stronger, mainly because they are re-usable. If you rebuild the engine/head once per year well having re-usable head bolts is a good thing right.

Now i just have to hope enjuku has them...
