You seem to be mis-informed. With the proper setup there have been S2000s cutting 1.4s - 1.5s in the 60ft. There is hardly a traction issue with those types of times, and those times are in fact better than what some AWD cars are achieving.

 

Completely untrue...


The only person to mention head float was cody from lovefab a couple of YEARS ago back when no one boosted the s2k. Since then, its been proved overall OEM bolts are more reliable then ARP studs.

 

I wouldn't go so far as saying "its been proved overall OEM bolts are more reliable then ARP studs". I am going to say now what I've been saying from the very beginning--any problems found after installing ARP head studs are primarily attributed to installation error. Most people installing these studs on their S2000 have not torqued them properly, have not used the supplied moly lube, and haven't retorqued the studs after heat cycling.

 

true...

 

Notice I never specified how the ARP studs failed

I'm aware they fail a lot due to improper installation, but if 9/10 people can't install them correctly, why chance it?

 

You didn't state that they failed, but you mentioned something about OEM head studs proving more reliable. That simply isn't the case.

10/10 people should be able to install them correctly. I installed ARP head studs on my wife's Evo and have had ZERO issues. I plan on having them installed on my S2000 when I have the engine built. When properly installed, ARP head studs give you a lot of extra peace of mind.

 

well overall, there are more failures in ARP studs verse 0 failures in the OEM bolts regardless of HOW they actually failed


10/10 people should be able to but somehow they still fail all to often which leads me to think they are not ALL improper installation.

 

The problem with that statement is the fact that there aren't many high-powered S2000s (high like 700rwhp or more) (I can count them on a couple fingers) out there and for those out there they haven't been in operation very long. I can all but guarantee you that the OEM head stud will fail (stretch) after being subjected to a high amounts of power over an extended period.

 

I will agree with that, definatly, but at only 21psi....highly doubtful. I've as high as 25psi with OEM bolts working perfectly fine.

Now if we're talking about 30+psi, I wouldn't recommend OEM bolts either

 

Great! We are on the same page regarding the OEM head bolts having a limitation when it comes to high-powered applications. Evo guys like to upgrade to ARP head bolts early in the mod process. Although my wife's Evo is only making 350awhp, we upgraded to ARP head bolts when installing the new cams. I wouldn't hesitate to upgrade my S2000 head bolts.
