Hi

I have read in many threads that the Std IC is pretty much useless & something about a *pressure drop* after 6000rpm which infact causes the turbo to have to actually work at alot higher psi than the reading showing on gauge (taken at the plenum) & that this is the main reason that you should upgrade to a FMIC before increasing boost as its will have better flow etc...

Could someone please explain this to me as i do not really undserstand the whole concept?

Also if i were to upgrade to a larger R34 GTT side mount would this eliminate the pressure drop or has it something to do with the piping etc & the fact that its a side mount?

Any help appreciated as i like to know all details (why is it better?/how things work? etc) before i do any mods

Cheers

Noel

www.are.com.au has an explanation of static and dynamic pressure drop.

with a standard turbo an R34 GT-t intercooler is an improvement and are cheap to install. they bolt straight up to an R33. there is no truth to the 6000rpm theory. if you push more air into the IC than its interior design will allow or beyond its ability to cool you will have issues. due to the same pipe run response is unchanged and you get an improvement in keeping charge temps down over a standard R33 SMIC.

(ps. i have an R34 SMIC if you are looking for one)

how much better is the R34 stock smic over the R33 stocker ?

I might be interested.

Also, while we're at it, is there much difference in response time when running 80ft :blink: of piping for a fmic, compared to the stock side mount's shorter piping ?

      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)
