I've seen it suggested that it's x100 mm Hg, ie 700mm Hg, which is slightly less than 1 bar (760 = 1 bar)

I think that's what on the cluster anywayz.

Makes sense..

I knew it was something like that.

the gauge is quoted in millimeters of heilium. This is a very old measurement which is pretty much obsolete. A stock HCR32 runs 10PSI of boost, this is what the actuator is set to, and what is displayed when you hook up an aftermarket boost gauge.

No, it's millimeters of MERCURY, 700mm of helium wouldn't be much pressure :D

It comes from when pressure was measured by seeing how much mercury it moved in a measured glass tube. It is also called a 'torr' 1 torr = 1 mm Hg.

either way you cut it the stock gauge is usualy wrong 1/2 the time anyways so just get a good aftermarket (not autometer) boost gauge and call it a day.

What's wrong with autometer? Autometer have been around for decades in the US and are made in the US.

I think you mean autogauge?

no i meant what i said, auto meter gauges are not as accurate as they tout.

my buddy with a rx7 had a auto meter gauge that said he was only boosting 7-8psi he threw on a greddy gauge (electric) and it showed boost to be more like 12.

just recently a buddy of mine dynoded his s13 hatch with a rb20 in it and the auto meter gauge read 11psi when it was really boosting 15.

from what ive been told the stock boost on a BONE stock gts-t is 7psi, however when the std exhaust has been dropped in favour of a highflowing one boost jumps up to 10psi.

From what you have been told is correct (sought of).

A stock R33GTST runs 7psi - RB25DET.

A stock R32GTST runs 10 psi - RB20DET.

RB20's and RB25's use different turbos, the RB25 (R33) turbo is slightly bigger than an RB20 (R32) turbo - therfore it can make more power at a lower boost level.

My R32 was running 10 PSI on my aftermarket Greddy Guage. After putting in a 3 inch turbo back egzorst it used to spike to 13psi and sit at 12psi all day - this is because the bigger egzorat is more free flowing and can get rid of gasses quicker - im sure on the exact technical term for it but thats what happens when you do egzorst mods to your car i.e: Air filter and egzorst.

    • 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.
