Turbo question/ Boost ?
Hey guys
Question on how much boost I could run on my stock motor.
Right now i have a turbonetics kit witht he t3/t4 hybrid turbo running around 8.5PSI. Just got a turboxs UTEC to run my tune and I have had a greddy Prospecb boost controller but hvan't turned my boost up at all. Only other mod I have on the motor is the SSV and pulleys.
Just wondering if anyone else is running close to this set up and how much boost can I put to my stock internals ?
Thanks guys

We did a dyno run on what I have it set up with now and i believe it was 359. Yea I guess with the right tune I hope to aleast get 400 out of it with stock internals

Read this twice: https://my350z.com/forum/forced-indu...for-noobs.html
Motors have blew below/above 400, but 400 is the average safe zone in this crap shoot... TUNE is always key.
Try and use the search button. You'll live longer around here if you do....

I think luck has more to do with it than the quality of the tune. These n/a engines are built with particular tolerances in mind and engineered to diminish failures to an acceptable level from a quality control standpoint. When you throw boost into the equation on a VQ the failure % increases substantially. Nissan knows a particular amount of n/a engines will fail at 100K or 140K (or else they would have be warrantying the powertrain longer than 5yr/60K or 6/60K like opponents). Your engine may be destined to last 150K+ and you put boost on it for 50K with no ill effects. Or your engine may have been destined to blow a head gasket n/a at 80K in which case you may only get 20K boosted before failure.
I think people who talk up the tune so much may be just trying to make themselves feel more confident that their engine won't fail. Yes, a tune further diminishes your chance of engine failure from running too rich or too lean, however proponents of "it's all in the tune" are being shortsighted out of convenience, in my opinion.
Search for "blown engine" in title or in the "how long did it last boosted" thread and you'll see plenty of blown engines with tunes from reputable factories.

So says the salesman.
Well I'm convinced, i'll go ahead and click on your link and buy Uprev or Haltech etc...maybe I'll throw a built engine in my cart too and go ahead with you guys installing my twin turbo.
Also... ROFL @ your website name too in context to this post
"www.failsafeperformance.com"
There couldn't be any bias to your well formulated refutation of my post...
Oh also, could you tell us what warranty you offer with your tuned turbo/built block installations? Just for any of us in the Oklahoma area...

lol this thread is going too winz
From what I've heard its not the HP its the torque that kills the rods. 400 Wheel torque should be a nice target goal, although most people who run the TN kit tend to blow their **** up if the kit isn't running on pretty much everything stock. Every single person I know (again just the ones I know) that ran the TN kit were fine until they changed things around.... BOOOOOM went the motors.
TN kit IMO is the perfect turn key kit for 350-360WHP on a pretty much bone stock car, for anything else go with something else. I just dont trust it.

yes tune is important, but it doesnt guarantee a reliable and safe motor.
People blanket statement, "its all in the tune" all the time, when thats just not true. I cant think of more than a few of ALL the built motor failures that were tune related.
The tune is one critical aspect but so is supporting part selection, driving habits, tolerances, etc.
