Oem turbo boost?

[krystalized_jdm]

What is the max these turbos can run? These are different turbos than the one in my gts. Needing to know how much pressure one of these could SAFELY push on stock turbo.

I would stay at or under 1 bar. Any more and the ceramic likes to go boom.

1.3-1.4 all day long w/ meth injection and a JDM chipped ECU for me. If they blow up they cost $100 used and there's probably a dozen or more on the classifieds at all times.

Just hope your right foot is planted when they go boom so the pieces go into the cat , taking your foot off when they go boom and the exhaust scavenging could cause alot of engine damage .. ceramic is harder than steel !

I did 1.2 bar for years. No worries.

Are you talking with one turbo on your gts? Or do you have a gtr as well cause if your only running one then 1 bar is way too much boost but I have been running at 1 bar in my gtr for a while now with 80,000 k on them and so far no problems. All depends how hard they have been run in the past though.

If your still running your oem clutch (like I was when I took my restrictor out... Oops) I would be more concerned about that for the time being. As long as you dont bag the car too much, the turbos should be fine. But like the others were saying, who knows how hard the previous owner drove it.

It's not boost levels that kill ceramic turbochargers, it's heat. Obviously more boost typically means more exhaust energy which equals more heat. You can run as much as boost as you want, so long as you control exhaust gas temperatures by running richer air/fuel ratios and compensating with more ignition timing.

1.1 bar is fine. go to 1 bar if you're scared of more and enjoy it.
