  1. Thanks for the replies. Stock intake. Someone told me that it is the sound of the nylon turbo fan, when it's about to say "goodbye". He had the same issue with an 2JZ. A bit worried about it.
  2. Hi all, how does the stock turbo of the R34 GTT sound during acceleration/boost? I almost cannot hear mine. It has a very high pitched whistle (not loud) and on highest boost moment there is a weird "drrrrrr" noise. I have no idea if that's normal. During pressure release there is also no sound at all. I know by installing an aftermarket BOV you get that typical loud blow off sound. But again.. is it normal that there is no sound at all? Boost gauge shows that everything is fine though. No boost control. I try to upload a sound file later.
  3. Thank you both. I hope you are right GTSBoy. I‘m going to check all parts for leaks this weekend and see if that solves the problem.
  4. No aftermarket, but I will check it. I just hope it‘s not a turbo damage. Just found this video and while driving it sounds pretty much the same:
  5. Thank you! I‘m going to check it. Would be surprised if the turbo is blown as I‘m driving on standard boost. On the other hand it‘s already at 160.000km. It‘s the stock one. Could it also cause the problem?
  6. Hi all, recently bought a Nissan Skyline R34 GTT with the RB25DET. So far everything runs great, however I noticed that the sound of acceleration is a bit weird. I'm not sure what it could be. Turbo leak maybe? I included a sound file in this post. Is the noise normal? Also, during the winter I might want to do some checkups. Would you recommend to do a compression test, even if I don't notice any lack of power or blue/white smoke? Thank you! IMG_5469.mp3
