hi all

i get this strange "choking/fluttering" feeling between approx 4500 and 6000rpm with my rb25det.

under and over this range the car feels strong as normal.

at 6000, it comes good again with a noticable increase in power.

First i thought it might just be the factory boost solenoid doing its thing because of the change at 6000 but now thats been disconnected - no change.

happens at standard and slightly raised (9psi) boost. same deal.

only mods are 3" cat back exhaust.

standard ecu/afm etc

i recently changed plugs to NGK PFR6A-11 ones re-gapped to 0.70mm

could this be my problem, too small a gap?

help! :)

is it manual tranny? my NA R33 does that too when i slip into the 3rd or 4th with lightning speed, the engine flutters abit then off it goes. i was wondering if it had anything to do with the gearbox because it doesnt happen in any other gearbox. i guess it could also be me dropping the clutch with no accel. resulting in a bouncy effect. Its more annoying then worrying

      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.

      R32 GT-R: 4WD Light Turns On After Bumps – Code 19 (ETS Motor) But No Issues Found

      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)
