Need help with cracked turbo manifold

Blackcrimzon

Back in 2011, I bought the HKS prototype twin-turbo kit off of a member here. I have had the kit on my car for the last 10 years with no problems up until today.

As the title says I have a cracked turbo manifold on the passenger side. Not sure if turbo manifold is the correct name of the part as I have seen a few names for it but to be clear it is the part that connects the turbo to the engine. The part that would be the headers if I didn't have a turbo on the car.

I was wondering if anyone has experience in this and how to fix it? I read a few posts online that JB weld high heat would work but I don't really think that would work. Unless anyone here has tried it and it worked.

I also tried to find another one on google but I can't seem to find one for a 370z and even if I did I am not sure if it would fit my turbos. I did write HKS and I asked them for some advice but I am still waiting to hear back from them. So in the meantime, I thought I would come here and ask all of you for some help. Any advice would be helpful. Either on where I might be able to buy a new one or how to repair the current one.
