i just bought 272 hks cams but didnt get the headstuds because i was told they werent necessary. Some say buy just for safety and some say they have done fine without it. I dont want to buy if it's totally not
necessary. opinions needed

 

They are not neccessary it is more of a safety item. I have 272's and I do not have arp headstuds. You will be fine with out them.

 

sweet thanks...long as i dont go above stock boost?

 

i've got cams... i boost to 1.5... car hasn't blown up yet

 

As long as you dont go over 22psi I would think your safe.

 

sweet..good to hear this

 

yeah going to keep my boost around 21psi

 

It's hard to say if you really need them. The main reason being that Evo's aren't old enough yet to see what long term problems exist. Maybe we'll findout when guys start getting into the 70K + on their cars.

People do headstuds because it's easy when you're in there doing cams. If you are doing the work yourself I would put them in. It's only $100 and some more of your time.

 

I've been running 28 lbs of boost for almost a year/10,000 miles + with no head studs. (Windshiled wipers work great to get the coolant off the windshield .)

No problems as of yet. You're probably fine.

I'll put them in when I push it to 40 pounds with twin 35R's

 

I have been over stock boost level and I havent had any issues! It's all in your tune on how your car will respond and hold up!

 

Tommi Makinen and 26psi on race gas with stock head studs and no problems here.

 

272's stock blots 25psi= blown headgasket for me
Now my car wont keep coolant for crap over 21 psi
as long as you dont go over 21.5 psi you'll be fine. My car didnt start acting up until i turned the boost up with a race gas tune

i would buy them

 

i am not messing with race gas..lol ..and i will only 1/4 a few times a month...so i think i will be safe like the others say

 

First time I've heard of this so were you tuned and notice detonation?? Would arp head stud would have save you is the ???? here

 

al recommends arp headstuds when u get alky injection! (360-400whp & 27psi of boost)
buschure is still using stock headstuds on 400whp.

i dont wanna touch the stock head bolts!
i am confused
