Do I need ARP head bolts for a 50trim upgrade.

[Onefast99gsx]

Hi All,

I'm bolting a PTE 50trim turbo on my 99 GSX currently as my winter project. I have no clue how much i will be boosting this turbo yet as i don't know where its limits are. I would guess I'd be boosting around 24-26psi on race gas.

My questions:

Do I need ARP head studs (mandatory) for this turbo/boost ????

-and-

Do i need an aftermarket head gasket of some sort (copper) ????

Thanks for your input.
