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:

      Baron's R34 GT-R build thread - car in Japan for 5 years -_-

      By BaronOBeefdip · Posted

      Back again. I returned to Japan in Jul/Aug to spend time with the car on my birthday and remind myself what all the sacrifice and compromise is for. It happened to line up with the monthly morning meet in Okutama, which I have been wanting to go to for a long time. It's a unique event at a unique spot with really rare, interesting, and quirky cars. It's where all the oldheads and OGs gather. The nighttime scene at DKF certainly has its place and should be experienced if you're into cars, but there's too much bad attention and negativity around it now. IMO the better time is Sunday morning at DKF or Okutama; it's more chill and relaxed. I'm glad I was finally able to go, but not sure it's worth the drive from all the way from Nagoya immediately the day before, unless I was already staying in Tokyo for the days right before the meet, because you have to wake up quite early to make it in time. Funnily enough though I didn't drive the car all that much this trip because it was just too damn hot. While there were zero issues and running temps were nominal and the A/C was strong, RBs already run crazy hot as it is. Sure, it took it all like a champ but something about driving these cars in the ridiculous heat/humidity bothers me and makes me feel like I'm asking too much of it. I'm just me being weird and treating the car like a living thing with feelings; I'm mechanically sympathetic to a fault. Instead I was mainly driving something else around - a KX4(silver) 2001 X-Trail GT, that I acquired in May. There's a few different flavors to choose from with Xs, but visually it's the Nissan version of the Honda CR-V. Mechanically it's a whole different story as this, being the top-trim GT, has an SR20VET mated to a four-speed auto and full-time AWD! It was a very affordable buy in exceptional condition inside and out, with very low mileage...only 48k kms. Most likely it was owned by an older person who kept it garaged and well-maintained, so I'm really happy with how it all worked out. It literally needs zero attention at the moment, albeit except for some minor visual touch-ups. I wanted something quirky, interesting, and practical and for sure it handily delivers on all three of those aspects. I was immediately able to utilize the cargo and passenger capacity to its full extent. It's a lot of fun to drive and is quite punchy through 1st and 2nd. It's very unassuming -in the twisty bits it's a lot more composed than one would think at a glance- and it'll be even better once I get better tires on it(yes, it's an SUV but still a little boat-y for my liking). So...now I have two golden-era Nissans in silver. One sports car and one that does everything else; the perfect two-car solution I think👍 The rest of the trip...I was able to turn my stressed brain off and enjoy it, although I didn't quite get to do as much as I thought. I did some interesting things, met some interesting people, and happened into some interesting situations however, that's all for another post though only if people really want to know. Project-wise, I went back to Mine's again to discuss more plans and am hoping to wrap that up real soon; keep watching this space if that interests you. Additionally, while working in the tormenting sweatbox that is the warehouse, I was able to organize most of the myriad of parts that my friend is storing for me along with the cars, and the 34 has a nice little spot carved out for it: And since it can get so stupid hot in there, that made it all the more easy -after I was standing there looking at the car and said 'f**k it'- to finally remove all the damn gauges that have mostly been an eyesore all this time. Huzzah. The heat basically makes the adhesive backing on the gauge mounts more pliable to work with, so it was far less stressful getting this done. I didn't fully clean it up or chase the wiring though; that will happen once I have the car in closer possession. Another major reason to remove all that stuff is to give people less reasons to get in my car and steal s**t while it's being exported/imported when/if the time comes, which leads us to my next point... ...and that is even though it's time in Japan is technically almost up since it's a November car and the X would be coming in March, I'm still not entirely sure where my life and career is headed; I don't really know what the future looks like and where I'm going to end up. I feel there's a great deal of uncertainty with me and as a result of that, it feels like I'm at a crossroads moreso now than any point in my life thus far and there are some choices I need to make. Yes, I've had some years to consider things and prepare myself, however too much has happened in that time to maintain confidence and everything feels so up in the air; tenuous one might say. Simply put, there's just too much nonsense going on right now from multiple vectors. Admittedly, I'm struggling to stay in the game and keep my eyes on the prize. So much so in fact, that very recently I came the closest I ever have before to calling it quits outright; selling everything and moving on and not looking back. The astute among you will pick up on key subtext within this paragraph. In the meantime I've still managed to slowly acquire some final bits for the car, but it feels nice knowing there's not much left to get and I'm almost across that finish line; I have almost everything I'll ever want for my interpretation and expression on what it is I think an R34 should be. 'til later.

      Thanks for that, hadn’t used my brain enough to think about that.

      R33 GTR running -9 with no tune

      Also playing with fire if they start to flow more air down low than what the stock twins can. It's not even up top you need to worry, it can be at 3000rpm and part throttle and it's getting way more flow than it should.

      You still want a proper tune on the stock ECU though. Stock tune + stock ECU with GT-SS/-9s is probably playing with fire if you're running more than stock airflow/power.
