when driving, usually when i rev to about 4-5 grand + i hear like a pinging noise.

ive put in octane booster prob about on 2 seprate occasions and it dosnt really help. just slightly.

does anybody know the reason of this? and if its a problem?

cause ive been told, that if u hear pinging, and u still give it, u can blow ur motor, so u gotta back off. is dis true?

also if it is a fixible problem,do u know how much sumthing like this would cost to fix?

thx

make sure you are running as high a ron as possible eg bp ultimate 98. what mods do you have are you still running stock boost. what car is it etc etc more details are probably required, make sure the engine is getting enough fuel etc etc

yea, 95% of the times i use 98 octane fuel, usually vortex, but only here and there i use premium unleaded from mobile (95 octane) only cause its all i can get.

i own a 93' r32 gtst, with minamal mods. 3" exahust and pod filter. also im running stock boost.

    • 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).
    • 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)
    • Yeah, shame. Maybe  driver's carpet is available 🙏. I am waiting for both amayama and nangun to confirm.
