this is the type i am thinking of, but more than likely with less coils

Looks good !

Put the cooler in the return-line, after it's left the engine bay, before it goes back into the tank. This is where the fuel will have the highest temperature, so You can get maximum heat rejection through the cooler. That also means it won't matter if there's some restriction in the cooler, since it won't affect peak flow to the rail.

The stock return into the main tank should be adequate, since You won't be pumping much more than the in-tank 040 does now.

Personally, I'd Y-Piece the two returns together into the main tank, that way the warm fuel from the rail doesn't heat up the surge tank, which has a relatively small heat-sinking capacity compared to the main tank. Make sense?

      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

      What brakes on R34 GTT(Europe)

      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)
