Hi, ive got a question about ARP headstuds. I bought Silverludesi's car recenlty and to just to let u guys know what ive got, heres a link:
https://honda-tech.com/zerothread?id=380514

The head was apart, and while it was i had Inline throw in some ARP's.
Right now i am running 7psi for low, and 10psi for high on my profec b....maybe up to 13 if the situation calls for it. This is on a t3/t04b .63 a/r stage 3 super v. I plan on runnin this turbo for a good bit, to just keep it a street car for now.

My question is, ive heard that i should retorque the ARP's after 500 miles? or 10 heat cycles? IS this totally nessecary?

My mech has said that he has also heard of this before, but hes never retorqued an arp, and has had no problems, but then again im not sure how many H series theyve worked on with FI.

The only reason i ask is that i am in school right now with no way of transportation,no tools, no time, and a very busy academic schedule. Otherwise i would retorque them myselves.

So what have been you're expiriences on boosted H or other series engines, do i need to retorque? Thanks for helpin a honda newb.

it is a good idea to retourqe, i am running the same studs, i never retourqed, but i sould and will prolly do it one day when im bored, but its not leaking do im not that worried

 

How much boost u runnin and what turbo? How long have u been running that psi on those studs? Nice to see another built h23
Just curious what setup ur runnin and what ur puttin to the ground. And how did u get H23 ARP's? i thougth i was the first.

 

If you have:
1 good cyl compression
2 no blowby in the crankcase
3 no compression in the coolant

then you have no reason to retorque but if any of these probs arise that's the first thing I'd check. There's no reason in taking it apart if you don't need to. next time you adjust your valves or timing belt check the studs. The arp are heat treated so they not supposed to streach.

 

Most peopel on this board think one should re-torque the arp s after a couple heat cycles. The problems u described is what im trying to prevent by re-torqueing the studs.....if i decide to that is.
