The biggest factor would be the tune not being stable. I imagine these two blown motors are not local? Local fuels can be quite different and effect a tune especially with E85. Also climate and sea level can as well. We also cannot be sure what boost they were actually running at the time...EBC's make it really easy for people to push too much. I wouldn't say that it is an issue with the kit. More or less the tune or user would be the more likely problem.

There are a lot of 500+ people here...

Yep, just a quick look I see 8 minimum over 500HP.

Also, SRPerformance, check your PMs. I want to finish the forced induction noob thread & want to make sure your info is accurate.

That is what I was thinki. S&R did the tune and perhaps thats the problem. As u can tell there's plenty of people pushing 500. This motor is stout and should hold much longer than these 2 kits did.
Just trying to make the community aware.
There's too many boosted cars out there to attribute to "bad" gas although it could be its highly unlikely.
Either tune/kit something might be off. Not trying to put S&R down jus tryin to maybe get u to look over something again.

Because if it isn't in that thread it doesn't exist :icon18: Seriously there a lot of people on here who don't post but every once in a while that probably aren't even in that thread.

I know 2 people running that local that aren't even on here and I am sure there are more through the US.

:wtf:
I am agreeing with you, saying that there are at minimum 8 at quick glance plus more probably. :facepalm:
I never said that was the full list of boosted 370z cars, it is a user database kept up to date as best as I can.

Yeah I am thinking it is the tune as well. Only reason I brought up gas is...atleast this is the case around me the E85 blends change depending on the time of year. So when your running a tight tune it can cause issues. I agree though there is certainly an odd trend developing around this kit. Hopefully VSR can comment soon.

ohhhhhhhh. My bad bro. My interweb skills are lacking today :ughdance:

I really thought you meant there were strictly only 8 builds. :roflpuke2:

If you do know plenty on their build post it up in the thread, will just call them unknown, I browse around now & again to find some online not on this forum.

Yeah there are some on the NICO forums and stuff like that. Ill try and gather some details...hopefully mine will be added to the list here in a month.

Lets get a couple things straight.

The G37 is a local build and that guy dropped a valve THAT HAS NOTHING TO DO WITH THE TUNE.
We have tuned well into the hundreds of Z's & G's and not have any blown up.

The truth is and i didn't want to throw any one under the bus. I installed a manual boost controller on his car. He raised the boost level after he left our chop at Z1.The tuner at Z1 even verified that the car was in great condition. Besides his engine blew up a year later. Again tunes do not change However mechanical can change. The customer also stated right before it blew it was running bad some hesitation and he decided to punch it. So there is no way this our fault

The G37 had a new engine installed by Infinti under warranty (don't Ask) and the tune is still on the car AND the car driven daily and beaten at the track. This car makes on 100 octane 658hp

We have done over a dozens of single turbo & Twins. If there was a issue the car it would have not made 14hr road trip back home beating it all way up north.

Like how everyone speculates or diagnosed the problem since no one has seen the car.

Can u blame anyone? Ur original response was vague in clearing anything up.
Where was this reply the other day when people asked? Smh

I will like to add that at 12 psi on these cars is pushing the limits of the stock block, this is from personal experience of a friend's car. The car had a stage 1 GTM the day before it died it maid 550whp on a dynojet. The car was driven hard for 13k miles and holds the mph trap speed record of 127 mph. I also know of 2 GTM kit's in the area one blew up and the other was caught just in time. Both of these cars have built motor's in them now, basically what I am trying to say is you just cant blame a kit things happen.


Like someone else pointed out in this thread double the power of the stock block.

Yes I know the potential of what can happen. Never know when it can happen. Now there's plenty of variables that come into play. Gtm is a proven kit that's been in VQ motor for years. There's faaaar more Gtm kits out there than SR kits. If I'm not mistaken I think I only heard of 3-5 MAX that have this single turbo kit? I think the number is far less. So this kit is fairly new. With 2 blown already. Doesn't look good. The response from the owner doesn't look good as well.

The last one to blow was not runnin high HP number. See where I'm goin?

Lastly. U said the one G that blew had numerous track and driven hard 13k miles. I'd be happy gettin 13k the way I drive. Valpozguy had no track days if I'm correct and only some spirited driving.

Just seems suspect on the out looking in. That turbo does look real close to the piping. Just wanted to bring to the owners attention maybe he can look into something that might be an issue or the tune might be off. The way he responded says a lot. I hope the fellow member goin that route with his built motor has better luck

It was a 370z nismo that blew up and lasted for 13k car did 11.7@127 and is on my youtube channel.There is also another nismo owner that only lasted a few months that blew up. Now when I say blew up I mean rod out the side of the block. Then you have Sharbycoop who has the G 37 that caught his motor just in time before it shot a Rod out the side.

Now I don't want you to think I am defending S&R kit,hell I don't even like design of it.
I am just trying to shed some light on the fact that these motor's can blow up.

Also you cant count a dropped a valve as part of this hell I can drop one in my built motor I am still using a stock head.

Here is a video of the pull.
