Hi guys just an update

Came back from the workshop and he said that it was likely the actuator on the turbo that is stuffed overboosting the turbo causing it to whistle.

I advised him at first that it maybe the gasket between the manifold and Turbo so he opened the bonnet and reved it. He said if it was a leak he would have heard it.

So we then went for a spin and at times the boost would spike to around 13-14 psi and make that whistling noise. When the boost only when to 10 psi it wouldnt.

So his diagnosis was that since he had removed the boost controller and put the stock bits in and it was overboosting that it is probably the actuator that is stuffed causing the turbo to overboost and make that noise.

Opinions please? Sounds plausible? Should I get another workshop to look at it before I decide to shell out for a new turbo.'as he said I just may as well buy a new turbo.

Any help much appreciated :)

I would say hes probably telling you the truth. I've unfortunately got an exhaust leak from my rear turbo and the sound doesn't come or go, it's always there. You can hear the 'airy' sound on decel and it runs like a bucket of shit. Have him finish of his work and before you pay the bill ask him to come for a quick lap to see if it's still doing it.

I doubt you need a new turbo.. more like the actuator hasnt been put on properly or you have a leaking hose, why not get in there yourself and eliminate all these possible causes, source a second hand acutator and try it yourself

i leaking hose would give you overboost, cost to replace =zip

get a bright light in there and look for any soot gather around the gaskets which = leaking gasket

make sure you dont have some garrett highflow, i never knew myself until i was told,

you dont have a cheap split dump pipe do you?

Just an update guys!

So after 2 weeks of being told the noise is my boost controller, then my turbo , then my actuator and dismissing that it can't posssibly be the gasket between the turbo and manifold, I dropped off the car to Rob at Sabbiddin Automotive to get the car checked out. I've had my car for their for mechanical work in the past and respect his professionalism.

I just received a call from Rob just then and hey prestoooo...It's the gasket between the turbo and manifold, and that there's a bit of shoddy work from the previous work :rolleyes:

Regardless I'll be eventually getting a new turbo soon, but didn't appreciate the advice from the previous workshop even after telling him what was the problem.

So just a shout out to everyone that helped and especially Daniel from Elite Racing :cheers:

I won't publicly name the workshop as that isn't appropriate & allowed and to a certain extent everyone makes mistakes, but I will say this workshop is in the South-eastern suburbs of Melbourne and is a workshop referred onto by one of the top Tuners in Melbourne that is regarded on this forum.

:thanks: to the SAU Community :action-smiley-069:

Glad to help. It's good that you found someone to sort it out for you. I was going to suggest someone when you asked but thought again about it. I was absolutely certain it was going to be that gasket so it is a good thing you persisted with it or you end up like every other poor bastard around.....even poorer and still without a fixed car.

Rule #2 is: If it smells like shit, feels like shit and tastes like shit....it's most likely not going to be a cheese sandwich

Thanks guys :cheers:

Just picked up the car and it feels great again. Rob said some bolts were missing, some bolts not tight, hoses weren't in properly ahhh i just had to laugh.

Now its time to save up for some ID 1000 injectors and a Hypgear turbo :thumbsup:

    • Ok I get you. But isn’t the butterfly intake a headache with the +T?  see this is my plan so far but please advise me into the right direction.  Nistune Ecu, 1000cc Bosch injectors, TD05 or TD06 Kinugawa turbo using stock rb25det exhuast manifold, walbro fuel pump unsure of model I think it’s 450/460, spitfire coils and sparks to suit and a R35 MAF sensor and boost sensor.    I was thinking maybe do a cheap eBay plenum $400-500 or try find a stock det neo intake. I think I’d port match it so it’s getting the full capacity but open to advice please.  Thanks 
    • The issue now is the 'fuel cut' while driving, and when it happend, it does not stall. This, I did not test the fuel pressure while driving as I cannot with a fuel pressure gauge. I do have Nistune logs, yes. I have also replaced the MAF Sensor.   Also related to the FPG Fuel Hanger – I just realized that I need a Deutsch Crimp Tool to crimp some cables for the FPG Fuel Hanger. Need to purchase additional cables as the kit only included 2, which are for the float. FPG has not responded to my emails so far since purchasing. I thought about taking it to someone and having it done professionally, but I am reluctant since everyone I took it to messed up in some way.  
    • There's a good German place in Brisbane if youre up for the drive 😛
    • The German place in Cabramatta was rock solid, fresh pretzel cooked to order back then. Then it went all quiet, after all the poker machines were removed, then I believe it closed for good. I did drive past the other week and noticed outdoor lighting a big screen, but no idea what is there now.  
    • Yeah I suspect even if you hold airmass per cycle/cylinder constant if you get too far away from stock you're still going to have problems running the factory tune within the bounds of the factory load scale. Cams, different displacement/rod ratio, etc. I'm just lucky that the GTIII-SS with wastegate boost + CA compliance cats is pretty much equivalent to stock turbos. When I have actual space I can finally get it tuned and modify the fuel system for flex fuel to 100% handle any detonation concerns when cranking the boost to whatever those dinky turbos can put out.
