GT Motorsports is carrying the only current turbo kit for the 370z, the Indonesian made GTM kit. This kit looks like a high quality system with cast mainfolds and Garrett ball bearing GT turbos. Although I don't think this has been tested on the Z, it has worked well on the G37.

What I wonder about is the VHR's 11:1 compression with boost on 91 octane fuel. GT motosports has reflashes for the kit via the Cobb access port or a semi stand alone HKS V-Pro.
Other than the 11:1 compression the VHR is built pretty damn stout. SHould make a good FA motor.
Mostly accurate post but there are a few discrepancies, the kits are not made in Indonesia - wondering where that information came from? The kits are all designed and manufactured by GTM, in the U.S.A.. Also the flash is being done via Osiris by UpRev, not Cobb. Testing on the 370Z should be done within the next month. -George GT Motorsports
Hi George,
Thank you for replying. For the Indonesia rumor, I am afraid that there is an Indonesian company that ripped off your design and is marketing there kit using your name. When Sarah and myself were researching avalible VHR turbo kits, I got an email from a asian website called alibaba that represents different manufacturing companies and they had a link to a company that claimed to make your kits. Here is the link to the bastards that copied your product. They fooled me.

I hate this sort of stuff, these sorts of companies are runing our industries. I hope you can bring legal action on these thiefs. Let me know if we can help, I will run an article to expose their fraud.
I am willing to do anything I can to help stop this.
We would also like to do a detailed tech article on the real GTM kit. Let me know what we can do! Sorry for giving these guys one bit of credit for your hard work.
I really feel for you, they fooled me, I thought that this was your company.
