I've heard that the factory boost gauge on the R33 GTS-t isn't very accurate.

Is the innacuracy mainly due to the meter, or the boost sensor itself? If the boost sensor is accurate, I thought perhaps I could use a more accurate voltmeter to replace the meter on the dash, as an alternative to installing a pneumatic boost guage.

I think when people refer to it being not accurate i think because it's so hard to read. Replacing it with a more accurate voltmeter might do the trick, but i can't see that as being better/good as an aftermarket boost gauge.

The measurement unit in std factory boost gauge is not PSI, but x100 mmHg

(millimeters of Mercury at 0 degree Celcius). It's actually written on the std

boost gauge if you look closely.

1 Bar = +/- 750 mm Hg

1 Bar = 14.5 PSI

Hence +7 on std boost gauge is 700 mmHg or about 13.5PSI

I have the Nismo aftermarket dash cluster, but it is still in x100 mmHg,

only the speedo that goes up to 300km/h (like I'm gonna ever reach it...)

as mentioned its not inaccurate like people say its just hard to read

is your tacho inaccurate? is your speedo inaccurate? no they're not and neither is the boost gauge

on the r32's the gauge is easier to see and read :cheers: but still a bit of a bitch.

remember aftermarket gauges attract theives so keep that in mind when wanting to add in stuff...

Waz.

also the factory gauge is way slower to respond than the autometer mechanical gauge im using, eg... you cant see boost spikes on the stock gauge

i was thinking of wiring up the apexi boost sensor (from avc-r) to the stock gauge, to see if if becomes more reponsive,

will have to use some adjustable resistor in series to get the right voltage signal

as mentioned its not inaccurate like people say its just hard to read

is your tacho inaccurate? is your speedo inaccurate? no they're not and neither is the boost gauge

on the r32's the gauge is easier to see and read :D but still a bit of a bitch.

lol, interesting question, both my tacho and speedo read high by about 10%

but, out of interest, what use is a boost guage?

The boost guage is the best thing i have installed. On the these hot nights, i turn my boost controller down and i get 10psi, then i can fiddle back at any time and get more psi, so easy, i love it.

I checked my speedo against a satellite speedo, and the tacho against PowerFC (also the fact the rev cut is at an indicated 7,200 not 6,900). They are definately not accurate in my car.

    • 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.
