R34 Gt Vs Gt-T

Hey guys,

I own a R34 GT-T and only recently realised during a clutch upgrade that it was originally a non turbo GT. Previous owner just replaced the GT engine for an rb25det neo but left the GT running gear in (gear box and diff)

Can anyone tell me the difference between the diffs and gear boxes of both models as my car made 200Kw last dyno run and i'm a bit worried I may be pushing the GT gear a bit to hard.

Also any opinions on upgrades would be appreciated thumbsup.gif

Cheers,

Luke

The RB25DE gearbag is the same as the RB20DET (ratios slightly different). ie, not really strong enough to handle the torque of an RB25DET (unless the RB25 is left fairly stock). The 25 turbo box is almost twice as big as the RB20 turbo box.

The diff is as strong as a turbo one. The only problem will be if it is not LSD, you will spin up one rear, which will slow you down, use tyre rubber and eventually break the diff if you twat about in it too much.

      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)
