4D55/6 ARP Head stud part numbers

...just wondering how my factory turbo is holding so much boost...

You know that Mitsubishi turbos get sourced as replacements for use on other vehicles? The Porsche guys rip the KKK turbos off their engines and use factory Evo ones, too funny
(don't know if it's because the Mitsu turbos are geniunely superior or they feel bad about getting their asses handed to them by guys in Evos and will try anything )

That makes no sense - they are ARP studs, way stronger than any factory stud / bolt, and they don't trust it? Then why are they selling it?

The thought is, those studs i listed are being flipped over and used the wrong way.
12x1.75 into the block would be using all the threads, but flipped it will only have a 3/4" nut on it. Far less surface area to grab than a 12x1.25

They do last a lot longer than most turbos, side note the stock turbo didnt even last a week at 30psi, but thats because i dropped throttle to fast in a quick panic and bent all the blades
