Hey All, I posted on here a couple months back about a few noises I had on my car. I was able to fix a few with a clutch and flywheel change, found out my dual mass had died. Swapped to an excedy lightweight and a heavy duty organic clutch kit. However, 2 of the noises haven't stopped. One of which I am almost 100% is my brakes which I will get looked at another time. The main reason for this thread is the main noise I get from my turbo (front left of engine bay where turbo is, may not be turbo though). It used to be intermittent, now it is almost constantly making this noise when I hit boost. It's easier for me to explain like this. When you floor a car, you should hear a clean and constant VVRRROOOOOMMMM getting louder. What I hear is this: vvvrr*TURBO KICKS IN HERE*OOOoooooOOOOOooOoOOOoooOOOOOooOOoOOooooooMMMMMM. My foot is flat the entire time, the engine noises gets quiet, then loud, then quiet, then loud, then quiet. Originally it was just an intermittent ticking noise which has now turned into this. The clicking is still slightly there, the only problem now is it gets drowned out by my engine not being able to decide how loud it wants to be. The entire rev range it feels like a smooth pull, but I have noticed lately while on idle it can be a bit temperamental. I had the car dynoed a few weeks back and it is making 161.7rwkw so there is no performance loss (completely stock jdm except the clutch/flywheel). I thought initially it was a stock boost solenoid being the issue, is this still likely? I have taken my car to a mechanic and they have said not to worry about it as there is no performance loss there may not be an issue. But I am certainly not hearing things and the car never used to do this at all and I refuse to drive the thing until it completely dies and maybe have to fork out 10x more than what I may now to fix it. I apologise if this is a bit hard to understand, I will see if I can get a recording of it making the noise over the next couple of days. Thanks.
