warning, Ebay'd ARP studs don't fit

[biosehnsucht]

I bought a set of these studs and they don't fit. They appear to be correct overall dimensions except they won't thread, comparing to the stock head bolts the thread pitch is obviously incorrect. I have emailed the seller to inform them they don't fit (so they don't try to sell any more as fitting, and to try and see if I can get a refund since they don't fit as advertised).

Just a word of warning, that Opel Vauxhall kit won't fit!

sonofabitchbastard! my blocks been at the shop so i havent been able to check it myself. i hope for some dumb reason mine fit

[biosehnsucht]

Did you buy yours from the same place ? If so I doubt it'll fit, unless they just mispackaged mine.

[f s t caz]

i bought from the same guy, but didn't get the U/C's.

[biosehnsucht]

Good luck, but I'm not too optimistic

I just bought a set too. They shipped today (I was already pissed cuz I bought them on Oct 1st). I won't get them till monday. Call them tomorrow and let us now whats up. There is a phone # at the bottom. It's 305-251-7018. You'll have to call a few times, as they never pick up the first time. I'm not super impressed with them so far...

[biosehnsucht]

Mine took awhile to ship but that was between/during hurricanes #2 and #3 or #3 and #4, I forget.

I emailed them last night and today they emailed back to send them back and they'd refund.

Does anyone remember offhand the correct thread size/pitch etc? I'd like to see if they can get a set of the correct parts instead of just a refund, that way also they'd know what to send out for CAs in the future; it's also possible that somehow I just got the wrong kit, another reason I'd like to be able to say "it should be X".

I think mine took ~ a week to recieve. But my heart dropped when i opened the box and pulled out the piece of paper that read Opel VAUXHALL Head Bolt kit. It took a little while to remember the awkward coincidence? that they were supposed to work for our motors and for Opel motors. you're right though, i'd much rather have the correct parts than a refund.

The correct ARP stud and nut numbers were posted on the old board by boost_boy. Unfortunately, that thread didn't survive the switch to the new forum. Also, one of our fellow forum members was selling complete sets of ARP studs/nuts and had them in stock. Hopefully he's still around and can jump in here......forget his forum name at the moment.

It figures. Both my sets did, but it sure as hell didn't come from ebay. That sucks though! Are they going to refund your money?

So did you get yours and they didn't work either? I'd kinda like to know what to expect when I get these on Monday.

Dee, did you have the Opel set too, and they worked? I'm frigging confused as all hell...

I dealt direct with ARP. I experimented with a set of studs and they didn't work. The main studs worked the 1st time around, but the head studs were sent back and were replaced with the correct part #s. If I can find my invoices, I'll repost the part #s. Word to the wise, on complicated parts for the CA18, you guys may want to avoid ebay. You just may very well end up getting played, screwed or misguided.

Thanks Dee. If you find the #'s we'd really appreciate it. I might send Aaron back down there with a gallon of 151 for ya!

No you won't

LMAO, I kinda figured you'd say that...

M11 thread with 1.5mm pitch

[float_6969]

^^ thanks! ^^

[f s t caz]

negative ghost rider, the regular studs do not fit as well.

[biosehnsucht]

OK so 11.5mm x 1.5 thread pitch, how long should they be? As close as I could tell the opel ones were long enough without being too long, but better safe than sorry. I'd like to be able to email them and tell them what I want, if they can't get it fine, I'll take a refund, but better to get the right stuff if I can.

[float_6969]

Well the ones from a VG30DETT are supposed to work, but if you buy that kit, you are getting an extra 6 sets (I think), and I think you have to modify the head just a little as the nuts don't clear or something. Something to think about...

Searching the archives, found:

Part #s are APN12-1 (10pcs)(nuts), ATP 5.060-1 LB (bolts) (10pcs), APN-58 (washers) (10pcs). Revised.............

[float_6969]

I just got of the phone with Daryl (Cuzan0) and what he used was a kit for the SR20. Only what he used was the Main Stud Kit. He said that he talked to Dee and that is basically the individual parts for the whole kit. Daryl said to just get the kit and it should work fine. He also said that you will need a thin walled socket to tighten the nuts up as it's pretty close quarters in there. He also said that the stud over by the thermostat housing will stick up a little higher, but it's not a big deal and tightens down fine. He's been driving his for a while with good power no problems, so I think this is the route that we need to go with.

On another note, I'm not calling anybody stupid (Unless you're Tim) but did you guys make sure you were trying to thread the right side of the stud into the head? There is a up and a down to them. Just thought I'd mention it....

[biosehnsucht]

Hadn't tried that but it did go half a turn before stopping..

Edit: wait, you mean SR20 kit should just work ??

[float_6969]

Ok, just got off the phone w/Al at ARP (great guy, BTW, very helpful) Here is the part # that we need to use. 202-5402This is the part # for the whole kit; studs, nuts, washers, and lube. Remember though, this is the part # for ARP's SR20DET MAIN STUD kit, but it's supposed to work perfectly on the head. (minus the minor clearance issue with tightening the nuts and the one bolt being barely longer)

[float_6969]

Oh, I almost forgot, you will be using the Nissan reccommended tightening sequence, but you will want to follow the torque specs that are included in the kit. Incase there is confusion, the kit comes with moly-lube. If you use THAT lube, then you'll want to torque them to 65-70ft/lbs. If you use oil (30/40W) you'll need to torque it to about 80ft/lbs. Remember to re-torque after the motor has been heated up and cooled down a couple of times.

[biosehnsucht]

The.. what.. huh? Really? That's fsckin' weird!

i handed the box to the guy that's working on my motor at the engine shop and he disappeared for a few minutes and told me that the thread was off and that they didn't work.

[fraz]

They are the same bolts as the RB20/25/26DE/DET series of engines. I dont think the rb series has the longer bolt for the front right hole

[r34 gtr]

i would be glad to tell you the part number on the kit i used if you still need it this weekend. only problem i had was that the front, intake side stud was longer than it needed to be, so i had to stack 2 washers on top of each other instead of just 1. other than that they worked great, went in first time.

i got mine from justin (justinmc), he carries them so if he's around somewhere he should be able to help you out.

- tim

edit: there isnt any real clearance problem, you just need the wierd 10 point socket or whatever ARP uses and when you run into a clearance issue, just turn the camshaft so the socket goes in ok. its really easy. also, i torqued my head down to 76lb/ft if anyone cares.

[float_6969]

Is it the same part # that I have listed? (202-5402)
