Grinding Noise/low Power..

Hello,

A few days ago my brother's car(hence why I'm a new user) started to develop this problem. The car is a 98 R33 GTS-T Automatic with 135,000km. Only mod is a catback exhaust.

The car is running very sluggish, with a lot of jurking. There is a loud grinding noise when accelerating, appears from about 2000rpm onwards, doesn't happen when idling though and the noise is coming from the turbo area.

Here is a video of it..

This video is just revving on the spot but it is the same while moving(if you can call it that). It would take about 10 seconds to get to 50kmph with even slower speed above that. As you can see on the factory boost guage it doesn't even get past -4.

I am suspecting that it's a faulty turbo. Can anyone give me some guidance for this?

Cheers.

      Yea - I mean I've seen my fuel pump which is decades old and uh, while I'm not saying this with real knowledge... but I sure get the ick at using anything in the fuel system that produced the state of that pump. Many years ago I went through multiple pumps (and strainers) before I dropped the tank to clean it out with extreme violence. I'm talking the car would do maybe 50km before coming to a halt, which resulted in me cleaning out the filter with some brake cleaner and going on my way. None of my stuff ever looked like what came out of your fuel tank. I don't think I'd be happy with it unless every single component was replaced (or at least checked/cleaned/confirmed to be clean here).

      What brakes on R34 GTT(Europe)

      I'm not going to recommend an EBC pad. I don't like them. Just about anything else would suit me better. I've been using Intima pads for a while now.

      Agreed, and in particular the earth strap that should go from the subframe to the chassis but it often broken or left off. There is a section in the R32 workshop manual you can follow for troubleshooting if you don't see anything suspicious, and depending where you are (there is no location on your user profile) you should be able to get your hands on a second hand replacement unit still if needed

      Yeah they mention as a R34 for 2.5 Turbo...but then again thos "small" were also for R34 by that different site. But i look into it and that 310mm EBC is for R34 GTT. And by those you linked the specs are the same 🙂    EDIT: I found these on one site here: DBA 4000 series T3 DBA42304S They are 310mm...and it says are for R34GTT...are there good? EDIT2: ok they have pads too.  What "color" should i get for street use? I dont want/need some noisy ones...(and if they are not that dusty that is good too)
