I have done a little looking around and cant find a conclusive answer.

Is the NEO 25DET intake different to the NEO 25DE intake? If there is a difference, can i bolt a set turbo runners to the n/a head, or should i use a completely different one?

Who else has a n/a neo head in their build - what have you found / what have you used?

Any assistance is greatly appreciated!

Chris

I'll be using my rb25de neo head on my rb30 build.

Basically they are identical, even the cams have the same duration and lift. They only thing im not 100% on is the springs, on the r33's the na's have softer springs but im not sure with the neo. Regardless if you are rebuilding the head all the aftermarket neo cams, springs, lifters etc will bolt straight in since the physical head is identical. All the exhaust and inlet patterns are the same so all the aftermarket manifolds for the gtt's will bolt straight up aswell.

      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)
