Yeah seems to be a bit of luck involved. I've hammered 10 pr 12 laps around Wakefield at 1 bar without hurting the turbo (spat a few other things though). Don't have a FMIC either. Other people spit bits of their turbo out at .81 bar. Go figure.

been running my 32 with exaust pod without touching the turb and it went to 11 psi just from that now its got a bleed valve to set it to 14.7 switchable and she is running nice and hard all day every day.

Then again im just waiting for it to blow so i can get a 2540 :)

I am looking to boost my GTR and waant to know is it always the case that all debris from the exhaust wheel goes down the exhaust pipe or is there ANY chance of any bits entering the exhaust ports. I can probably live with the replacement cost of a turbo but don't want to stuff the head/valves etc.

i was told if u back off it can go back in the motor ?

anyone know?

ed,

wasnt aware that 32 turbos are a bit more heat resistant. :D kinda happy about that i must say, though i  still want  a 2540 on it.

Its not that 32 turbos are more heat resistant, Its more the fact that the rb20 produces less heat to the turbo than rb25

Its true that a steel wheel will take more heat than the ceramic one. But if you take a RB25 turbo and put it in a RB20 you will be able to run more than 14psi that is possible in its original application.

I did not know that the RD20 turbo had a steel wheel? Why did nissan go to the ceramic one? Maybe for a quicker spool up yime or something...

The biggest mistake people make with bikes, Karts, and cars is forget the guy who designed the thing had a fair idea.... After all he earns a heap of Yen and would be out of a job otherwise.

Safest boost level is standard... end of story! It allows for fuel variables, worn engine components and is working with its mate the ECU who was born the same day.

Additional boost = additional performance. and the reliability is inversely proportional.

That is why most performance mods are sold as a package... and considering you can hardley notice <20kw, it becomes a game of chance, you decide at what level you wish to play...

Good Luck

    • 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).
    • 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)
    • Yeah, shame. Maybe  driver's carpet is available 🙏. I am waiting for both amayama and nangun to confirm.
