mospeed Posted July 27, 2009 Share Posted July 27, 2009 Total Loss of power.. Mods are.. -Apexi power fc d jetro (no mafs). Mods are: -Turbosmart boost controller -K&N induction -turbo back 3" SS exhaust -2 x Garrett GT3076s. I lost all boost when driving a couple of weeks back. Have checked the plumbing for leaks, turbos, DVs, Engine compression.. all seems fine. Injector opening on the dashtop display indicates 10% at 100% throttle and boost is -0.30 at full throttle. No misfires, burning is good, consumption is fine. Please help! Link to comment https://www.sau.com.au/forums/topic/280968-help-with-my-r34-gtr/ Share on other sites More sharing options...

Drift_Online Posted July 27, 2009 Share Posted July 27, 2009 Could possibly be a problem with the actuators on the turbo's, I had a simular problem a while back on an s14 wasnt making boost & thats what it ended up being, Link to comment https://www.sau.com.au/forums/topic/280968-help-with-my-r34-gtr/#findComment-4738298 Share on other sites More sharing options...
mospeed Posted July 27, 2009 Author Share Posted July 27, 2009 Both Turbos and Actuators are brand new! Even disconnected the hose pipes to the actuators to confirm. Still no boost!

KR4-GTR Posted July 27, 2009 Share Posted July 27, 2009 I had this issue, was an AFM problem. On a side note, maybe if you sell me your standard r34 gtr rims you could get a mad set and your car would look even better - boost or no boost?

zebra Posted July 27, 2009 Share Posted July 27, 2009 Rag stuck in the piping?....ive seen it too many times to be funny anymore Link to comment https://www.sau.com.au/forums/topic/280968-help-with-my-r34-gtr/#findComment-4738389 Share on other sites More sharing options...
R31Nismoid Posted July 27, 2009 Share Posted July 27, 2009 test as close to the turbos as you can for boost. No boost = actuator/turbo related If there is, you've got leaky piping And considering you have two turbo's, its fairly unlikely they both blew @ the same time, you should still be making some boost so i still suspect leaky piping or similar Link to comment https://www.sau.com.au/forums/topic/280968-help-with-my-r34-gtr/#findComment-4738470 Share on other sites More sharing options...
mospeed Posted July 27, 2009 Author Share Posted July 27, 2009 I actually suspected the turbos at 1st and ordered brand new ones from ATP. You can imagine the shock I got when I saw no boost after installation! Actuators are HKS and are working fine. Funny thing is a couple of days ago the boost actually went back to 1.2bar and held briefly (2 minutes) before dropping back to -0.30 bar! Very confusing.. am actually losing hair over this.

mospeed Posted July 27, 2009 Author Share Posted July 27, 2009 Damn.. u may be right! Thinking about it, I'd stuffed some newspaper in the piping when I sent bits for polishing. The problem started the day I put everything back. But funny thing is, the boost came back briefly a couple of days ago then disappeared again. It's not even giving me atmospheric pressure man! The gauge reads -0.30 at full throttle! Too frustrating.

mospeed Posted July 27, 2009 Author Share Posted July 27, 2009 Thanks for the tip.. Problem with the rims are they are the Black Z-Tune Nismo ones. You probably won't like them.
