I have just noticed a strange whining sound that comes on when I'm on moderate to hard boost up hills in 3rd gear. This has only happened a handful of times but would like to get on top of it early if it's an issue worth fixing. Any thoughts?


I am unsure as to whether it sounds like it's coming from the gearbox or the turbo? (The car is on 150,000kms and the turbo has never been serviced or highflowed so I'm expecting it to let go sometime soon but thus far no issues with it at all)


Any thoughts would be helpful

My car has sounded like a high pitched jet engine since I bought it some 50,000kms ago haha.

I was hoping that wasn't case, it isn't as loud as people say it sounds just before it goes.

How do people typically go about getting the turbo serviced? Does the engine have to come out to get to it? I have limited mechanical experience but do have friends who could help out, is it something any enthusiast with moderate mechanical skills could do and then get it sent off for a high flow? Sorry if this has been covered.

It is a big job. The motor doesn't need to come out. There is a few tricks to know which you can find by searching a bit on here. And a few custom tools seem to help a lot. Depending where you are located there are a few guys who can do ut for you at a reasonable cost considering the work that is required.

Just removing it to get sent off. Jetwreck is still doing some stuff. Would be worth hitting him up.

I got mine high flowed by precision turbo here in sydney and I'm very happy with it

    • Yeah, it's getting like that, my daughter is coming over on Thursday to help me remove the bonnet so I can install the Carbuilders underbonnet stuff,  I might get her to give me a hand and remove the hardtop, maybe, because on really hot days the detachable hardtop helps the aircon keep the interior cool, the heat just punches straight through to rag top I also don't have enough hair for the "wind in the hair" experience, so there is that....LOL
    • Could be falling edge/rising edge is set wrong. Are you getting sync errors?
    • On BMWs what I do because I'm more confident that I can't instantly crush the pinch welds and do thousands of USD in chassis damage is use a set of rubber jacking pads designed to protect the chassis/plastic adapter and raise a corner of the car, place the aforementioned 2x12 inch wooden planks under a tire, drop the car, then this normally gives me enough clearance to get to the front central jack point. If you don't need it to be a ramp it only needs to be 1-1.5 feet long. On my R33 I do not trust the pinch welds to tolerate any of this so I drive up on the ramps. Before then when I had to get a new floor jack that no longer cleared the front lip I removed it to get enough clearance to put the jack under it. Once you're on the ramps once you simply never let the car down to the ground. It lives on the ramps or on jack stands.
    • Nah. You need 2x taps for anything that you cannot pass the tap all the way through. And even then, there's a point in response to the above which I will come back to. The 2x taps are 1x tapered for starting, and 1x plug tap for working to the bottom of blind holes. That block's port is effectively a blind hole from the perspective of the tap. The tapered tap/tapered thread response. You don't ever leave a female hole tapered. They are supposed to be parallel, hence the wide section of a tapered tap being parallel, the existince of plug taps, etc. The male is tapered so that it will eventually get too fat for the female thread, and yes, there is some risk if the tapped length of the female hole doesn't offer enough threads, that it will not lock up very nicely. But you can always buzz off the extra length on the male thread, and the tape is very good at adding bulk to the joint.
    • Nice....looking forward to that update
