Blown HR Engine!

it could've even been bad gas but he says he was at WOT at 5k rpm.
i wonder how the a/f ratio is on the tune he has with the block. it does scare me how the VQ35HR is a high compression to begin with. at least the connecting rods are strong and those didn't break first. really suprised at the piston

Heres a couple videos of midz350's car. Notice the strange rattle when he lets off the throttle.

Let me start by sharing my condolences with the OP. However, there's always risk when taking a normally aspirated engine and adding forced induction. We can minimize the risk, but never eliminate it completely. Anyone doing this sort of thing must accept these facts.
If a customer comes to us asking for a guarantee on forced induction, we tell them to keep it stock. Even then, there are no guarantees, as we know of a couple people on the370z.com that have blown their motors with nothing more than exhausts and intakes. Having said that, we have done certain things in designing our turbo kits to try and mitigate the risks associated with forced induction. For example, our fuel system that we supply with our Turn Key kits is basic, simple, and effective at ensuring adequate fuel pressure. This system does not require a vacuum hose that could pop off and cause a fuel pressure drop. In the early testing of the system, we installed a fuel pressure gauge on our R&D car and the fuel system pressure was consistent all the way to redline. This fuel system has been proven to work very well and safely even though it is a returnless fuel system. Since we are using the factory ECU for tuning, the separate fuel trims for each individual cylinder to compensate for the returnless fuel system is retained.
When it comes to ignition timing, flashing the ECU ROM has been very consistent and reliable. Anybody who installs a forced induction kit should verify the Air/Fuel Ratio before ripping on the car. Even the timing values can be verified with a proper dyno test and the cable we supply with our turbo kits…that allows any parameter to be logged: Timing, Base Fuel Schedule, Water Temp, Air Temp, Wideband O2, MAF, etc. So if there is any problem with the install or even the tune, it can be detected and rectified accordingly. In a nutshell, if you install a turbo kit on a car, you put it on the dyno, verify the AFR, you verify the timing values to be safe for the application, what else can realistically be done? The risk can be minimized, but never be eliminated.

Judging from the video's sounds like it was
