I didn't see any available on the ARP website. If you find out they make studs let us know because I will want a set. As soon as I can find a used RB headbolt I am going to see if it's the same one. If so there are several companies that make head stud kits for the RB, guess I get a few extra!

I'm using stock bolts, try Courtsey Nissan and get teh discount (might be worth it) otherwise look up Pinacle nissan in AZ they have really good parts prices as well.

ARP doesn't make head bolts for the CA18 (period). They make them for the SR, KA, VG, but not the poor CA. The stock head bolts are very good and if torqued correctly, they can hold as much boost as you can pump out. $105.00 for CA18 headbolts and washers is a rip-off. I got mine for under $60 hear at esserman nissan here in miami.

they are the same! That means if you can find a stud set for an RB20 or 25, NOT AN RB26, you have CA studs with a couple of extra.

I would take it that someone has researched to determine if ARP makes head studs for those motors. The stock ones seem to hold up pretty good, but if there's something a little stronger then we all are very interested.
