miskyline94 Posted October 18, 2016 Share Posted October 18, 2016 Car stalling while driving with new turbo hi all, i just replaced my turbo on my gtt from factory turbo to Garrett gt 30/76 internals on my factory housing. when i drive at a rpm over 3k and put it in neutral the revs will go all the way down till the engine stops. does anyone have any idea why this could be ? thank you Link to comment https://www.sau.com.au/forums/topic/467306-car-stalling-while-driving-with-new-turbo/ Share on other sites More sharing options...
hardsteppa Posted October 18, 2016 Share Posted October 18, 2016 Either something not connected/air leak or something not plugged in/electrical.

miskyline94 Posted October 18, 2016 Author Share Posted October 18, 2016 ok thank you cuz the car also over boosts but i assume thats just the factory computer @hardsteppa Link to comment https://www.sau.com.au/forums/topic/467306-car-stalling-while-driving-with-new-turbo/#findComment-7784728 Share on other sites More sharing options...
Dose Pipe Sutututu Posted October 18, 2016 Share Posted October 18, 2016 take a photo of your turbo setup, and focus on the intake pipe @miskyline94 Link to comment https://www.sau.com.au/forums/topic/467306-car-stalling-while-driving-with-new-turbo/#findComment-7784738 Share on other sites More sharing options...

Dose Pipe Sutututu Posted October 19, 2016 Share Posted October 19, 2016 factory pipe work.. could be leak somewhere.. Are you running any wanky BOV? or is everything stock except the turbo? Also it might be overboosting because the turbo has a larger actuator on it.. not ECU related.

miskyline94 Posted October 19, 2016 Author Share Posted October 19, 2016 It's a factory bov but it is blocked of to re-curc and I have a front mount intercooler other than that its stock Link to comment https://www.sau.com.au/forums/topic/467306-car-stalling-while-driving-with-new-turbo/#findComment-7784777 Share on other sites More sharing options...
admS15 Posted October 19, 2016 Share Posted October 19, 2016 unblock bov and see if problem goes away. Link to comment https://www.sau.com.au/forums/topic/467306-car-stalling-while-driving-with-new-turbo/#findComment-7784802 Share on other sites More sharing options...

miskyline94 Posted October 19, 2016 Author Share Posted October 19, 2016 Why would the bov have anything with the engine stalling when I come off boost cuz the pressure is just going back though the turbo ?

admS15 Posted October 19, 2016 Share Posted October 19, 2016 The pressure is also going through the air flow meter backwards. The ecu sees this as additional air flow and injects more fuel. On some cars with air flow meters this causes stalling problems on others just rich running, unless the ecu has been tuned for it. Try unblocking and see what happens. Im sure dosepipe will correct me if im wrong 1 Link to comment https://www.sau.com.au/forums/topic/467306-car-stalling-while-driving-with-new-turbo/#findComment-7784999 Share on other sites More sharing options...
miskyline94 Posted October 19, 2016 Author Share Posted October 19, 2016 ok thank you @admS15 i will give it a go today. really appreciate the help and i am no expert. will let you know how it goes Link to comment https://www.sau.com.au/forums/topic/467306-car-stalling-while-driving-with-new-turbo/#findComment-7785001 Share on other sites More sharing options...
miskyline94 Posted October 19, 2016 Author Share Posted October 19, 2016 Also i might add, the reason i changed the turbo is because the factory one shit itself but when it went out there was a bit of oil around the intake hoses, so i was wondering if some of that oil would have gotten on the AFM. should i remove it and clean it with contact cleaner? @admS15 @Dose Pipe Sutututu Link to comment https://www.sau.com.au/forums/topic/467306-car-stalling-while-driving-with-new-turbo/#findComment-7785006 Share on other sites More sharing options...
niZmO_Man Posted October 19, 2016 Share Posted October 19, 2016 Cool, plumb the BOV back as per factory and see how you go. Link to comment https://www.sau.com.au/forums/topic/467306-car-stalling-while-driving-with-new-turbo/#findComment-7785035 Share on other sites More sharing options...
miskyline94 Posted October 20, 2016 Author Share Posted October 20, 2016 will do, but also for my peace of mind, would it have anything to do with the factory ECU? @niZmO_Man Link to comment https://www.sau.com.au/forums/topic/467306-car-stalling-while-driving-with-new-turbo/#findComment-7785050 Share on other sites More sharing options...
GTSBoy Posted October 20, 2016 Share Posted October 20, 2016 Well, the factory ECU will certainly not be happy about the much larger quantities of air that will flow. You MUST get an ECU or at th every least a Nistune board into this car.

miskyline94 Posted October 20, 2016 Author Share Posted October 20, 2016 ok so i there is nothing the bov is doing to the stalling, but we did rasie the idle a tad so the car has stopped stalling and also must of fixed the over boosting problem. a new ECU is defs on my list but money wise it is not going to happen very soon. and whats a nistune board? easy install and pricey? @GTSBoy Link to comment https://www.sau.com.au/forums/topic/467306-car-stalling-while-driving-with-new-turbo/#findComment-7785277 Share on other sites More sharing options...
