spinr33 Donating Members 964 Member For: 13y 6m Posted 14/06/12 12:20 PM Share Posted 14/06/12 12:20 PM Hi Guys,Im having afew problems with my car atm its a BA turbo 03 the problem is its currently making no boost,About 2 weeks ago it was dyno'd after fitting another engine with valve springs as previous engine started knocking badly, and found to be running lean and 14psi (previous owner had it tuned ?), my tuner couldnt get the boost lower so pulled timing out and maxxed the injectors so I could limp it home.I havent been driving it until I saved up the money todo the exhaust and injectors and re-tune it properly anyway today I got a new 5" venom cat installed and the middle muffler removed and straight pipes fitted, then took it to the tuners to get the 60 pound injectors fitted and retuned.Anyway later in the day I get a call saying that its making no boost and would need ti be their another day to sort it out.Is their any common reason that these turbos make no boost as it had previously held 14psi with no issues other then the lack of fuel, I have read all the other threads I could on the topic and common things seemed to be boost leak - intercooler hoses coming off , split hose on the throttle body , possible diagpahram failue in the actuator, possible sticking of the wastegate, actuator not sitting on correctly rod alignment etc.I would love anyones other ideas or experiences they have had that might help me, the tuner I am using is mostly Expensive Daewoo based but has done alot of turbo supercharged v8's so I trust him todo the tune correctly but has only really done my turbo and a couple of others.So im hoping someone might have some usefull info to speed up the process that I can susgest as I also live 2 hours away for work haha not having good luck with this car atm.All help appreciated Thanks Rory Link to comment Share on other sites More sharing options...

Not saying this one atm doesn't but I'd prefer going to a tuner who has done 23 turbos as opposed to 3 turbos.Who you with atm? Link to comment Share on other sites More sharing options...

Good luck mate and let us know what the drama was..nothing worse than someone bringing up a problem they're having and never follow up with what happened! Lol..just incase someone else comes on here with the same problem and searches and comes across this thread Link to comment Share on other sites More sharing options...

I ask this as if it was stuck on 14psi it sounds like it has an uprated wastegate actuator installed, hence not being able to get any lower than that. I would have hoped your tuner could have figured something like that out. The engine that has gone into your car cant take the tune with it unless it came with the ECU as well from my understanding.As for no boost could be all kinds of things as stated earlier in this thread. Hope you figure this out. Link to comment Share on other sites More sharing options...
