I currently don't have one on my car, I ordered two from Saikou Michi custom catch cans at the end of May and I am still waiting on them.

Just wondering why you went with a stock head gasket instead of something like Cosworth? It's not the first time I've seen it done and my shop actually said it would be better to go with stock. Thoughts?

Too bad HKS doesn't make a VHR head gasket... Those are the best gaskets.

You hit it right on the nose my machinist recommended it to me , also from research I have notice people using it .


So far so good with the stock head gasket 17k miles .

Stock head gasket is strong enough to use one on new build paired with ARP head studs combo it will be as good as you want it to.

On more than one occasion, engine builders have recommend the stock head gaskets for HR/VHR turbo builds. I will be using these on my upcoming build as well.

Excellent, thanks guys.

Any updates on the beast?

The beast is in hibernation in my garage for the North East Winter upgrades coming in the spring time.

patiently waiting :driving:

Cant wait to see what you do next

Great build! Any reason you are going with the single? Slower spool up isn't a concern? Curious on the daily drivability of your setup. Thanks

The pond he plays in has a huge power level entry point. One turbo > than two when it comes to efficiency.

of course, always worry about compressor efficency ranges, but if you overlay his dyno to some of the single builds out there, no comparison <4000 rpm. I'm looking at boost levels below 20 psi, which isn't exactly pushing the limits for some of these turbos, i could see in the 20+ psi range you would want to go single, but he has far more torque at the same boost level. with c16 there is no reason bigger turbos can't run >700rwhp, nobody here has dynoed with real race fuel to this point.

The reason I am switching is for peak performance I want more power.The GTM kit with log style manifold .64 A/R housing was just not cutting it anymore. I am not concerned with slower spool with the twin scroll 6766 setup. I waited a year for GTM V2 manifold's and was going to switch to GTX3076r turbo's with it just got tired of waiting. There is not a single 370z with that setup yet.

To sum it all up I am willing to give up some low in spool for top end power. I use the car for highway pulls and roll racing. Also daily driveability was not a problem with my old setup.
