I think there should be a distinction between a kit blowing an engine and just general FI causing an engine to fail. Some kits out of the box have failed engines, this one went for a while and had mods and retunes so it then falls into general FI failures.
Second not all engines will be the same, there are manufacturing tolerances and also manufacturing defects possible where one engine will fail and another one wont given same kits and mods. Some even have blown in NA form as mentioned before.
Third a failure usually cannot be determined by the conditions at the time of the failure, a piston failure definetly happens over time and a rod more than likely as well, it will take the beating until it just says enough and fails. For a rod to fail instantaneously it would have to be such a force that it is hard to believe it would happen while running the car.
Only way to be sure is to build the engine with forged internals which are made for that. I just hit 40k miles total on stock block with 20k on FI and still running.

Not to hijack this thread but...
Sorry to hear your loss. Did I hear that you are considering using GRD? I just dropped my car off with them and they are extremely helpful and kind. I'm sure that they will help out a lot.
For those that used GRD, did you have your car dyno'd at their shop before you had the FI installed? If so can you PM with your results? Thanks.
End of Hi-Jack...

Obviously, I'm not pointing any fingers at the kit, the installer or the shop that did my last oil change. It could be as simple as I didn't monitor my fluid levels close enough or my internals were some of the weak ones. This is my first FI car so who knows.
One thing I've noticed and I hope this is genuinely understood, I really appreciate and I'm amazed at all the sympathy and encouragement from you Z and my fellow G owners. This might sound silly but it really helps knowing you guys understand and want to help. Thanks again guys! Man, what a great forum.

While others blow after mods and tuning and at that point it will be from bad tuning or attaining power level above the capacity of the engine.
BTW it is whether not weather.

Brian, sorry to hear about the engine failure. It must def. suck since your car is down and now the wait begins, but hopefully the disappointment will turn to excitement as you plan for the built motor. Reading this kinda stuff is making me speed up my engine plans for sure. I hate down time.
Good luck!
Ron

I didn't respond to that to start a tit vs tat debate, only to point out that your over-generalized response is just that.
By the way, your first "sentence" is a run-on and you misspelled "definitely" in your first post.

Between the different FI systems for the 350z that I have experience with, they all leave TONS of room for improvement.
Maybe its because I am submerged in this industry on a daily basis, but with these types of FI kits, the only thing they are worth to me is a set of manifolds, turbos, and pipes. The rest of the kits are essentially garbage IMHO.
But even being a business with full fabrication capabilities and experience designing/building higher end FI systems from scratch, you have to weigh out the time vs. money. This is a car that is hardly worth most shops taking the time to build a custom system for targets of less then 800rwhp.
The risk is not associated with what kit you decide on, the risk is associated with the consumers understanding of the supporting modifications that are needed, and the selected tuners experience and understanding of what the vehicle needs and also their salesmenship abilities to convince the customer to put the money where it counts.
It doesnt help the situation that we have handfuls of nutswingers that you cannot avoid. All they do is post and post about how what they have is the best and how their tuner is the best, when the reality remains that they have no idea what they are talking about and they are trying to make comparisons when they have no experience with what they are comparing. A car that drives "perfect" and runs "flawless" to most guys, is a complete POS to me.
