Sounds to me that alot of people that do it themselves are blowing motors when they are done putting it on. Could there be something they aren't doing right? I think the motor can handle a good about of power with the right supplys. Just hope the people installing the kits themselves know what they are doing.

Regarding the Greddy kit, it far from perfect out of the box. But in my opinion, its a better setup for really high boost applications. The APS turbos, with their current wastegate can only boost to 12psi. This has been confirmed by several members I have spoken with. Now, the wategate can be upgraded, but apparently, Garrett and APS are very unresponsive at helping these customers out. Several calls to Garrett and they unreturned.
Hopefully, people will be able to find parts, maybe from HKS, that will work with the turbos included in the APS kit.
The Greddy system with optional return fuel system, Walbro 255, and shielded CAS, and a REALLY good tune....are a strong setup.

Greddy is capable of putting out more power with the stock turbos. APS cannot, and so far, is not showing any signs of being able to do so.

It's tragic to say the least . . . I run a basic Greddy kit (stock maps, no ignition timing or fuel solution) and have yet to have any probs--knock on wood Something as simple as wiring up the boost controller incorrectly could lead to 9lbs + . With the stock maps being extremely rich and the boost really low (5.6lbs), I cannot fathom a blown engine.
Now if someone created their own tune and didn't address timing and / or fuel, it seems plausible.

So basically u guys finished the install and took it out for a spin and the engine blew? Did u have a boost gauge? Maybe u got a huge boost spike like another member here and blew it.

Any GReddy kit that has blown a motor was due to the owner's own fault for not doing research IMO. (assuming you didn't push the limits of the rods (which are around 450-500rwhp)

I may be beating a dead horse but if the pistons and rods aren't the issue then whats the point in forged internals? I know why but still, I find it hard to believe that in just a matter of driving home Dave's internals completely failed. He was barely hitting boost and the engine blows while there are other Greddy kits that ran perfectly fine for a good while not to mention the other kits that are running safely, I'm no expert but that doesn't scream bad internals to me.
I guess my question is does your friends shop have experience with installing Greddy kits on 350Z's? If the wrong issue is addressed then the same problem is liable to happen again, even with forged internals. (it just may take a little longer for it to happen) Were you hearing any noises before the failure? I'm not sure how easy it would be to hear pre-ignition or detonation though.
I know it has been brought up and debated but oil starvation is another possibility.

G3po, cant wait to see how yours is gonna turn out. When are you coming down so we can meet up. I was there when you called yesterday, how funny hahahah.
I can't belive to this day Greddy sells these things...The turbos themselves might be great and all but the kit is not engineered in my opinion to be installed on these cars. SHould be called Greeedy because thats what it seems like they are.
And whats up with APS Not returning calls about boost levels. They need to man up! Lucky they have a good product.
