When should i get ARP Head studs? Only if I run higher boost or what?

 

When u want to run more then 22 psi on your motor or when u exeed 320 whp But i guess thats my personal safety barier

 

Damn! then I think its TIME! I might have a little over 325AWHP and im running about 20-21PSI.

 

???

 

It's more a safety precaution when you're going to run higher boost

 

I dont have it yet.. and its my next mod of my to do list..

 

I got mine when I did my cams, saved a little on install charges.

 

mid 20's with stock turbo and head gasket i think you are fine. that is what i still have on mine for now(evo). i will only change to arp when i get my turbo kit on. even with the arp on my talon, head gasket still let go at 29 psi with a 60 trim. i think if you need arp's then you also need head gasket. don't know any evo owners who had a head gasket go with stock turbo on(due to not having different headstuds).

 

I'll probally change mine if I ever do cams...

 

well about the gaskett though i read that the evo one is much better then most cars head gasketts... but i will be changing mine with my cams just cause i plan to do a big turbo... i would say at 21-22 psi ur fine anything higher and bigger turbo might as well its like a 90$ safty part

 

i know a guy running a gt35r that trapped 127mph and he has yet to get head studs, I say just get them when you get around 350whp for safety.

 

ive run 24 psi a couple of times at the track

on pump i run 21,5 psi every day

 

when u get new cams =D

 

Nothing the stock turbo can put out is worth installing studs on. If you have the valvecover off though for whatever reason, might as well install them. 27psi and 130 traps have proven that a tuned car should not require them.

 

don't get studs unless you're building up your engine. Stock is fine and i've never heard of any of the stock headstuds failing.
