Almost. The standard gauge is mmhg or millimetres of mercury. 7 on the gauge (which is 700) equals 13.5 psi

ok well explain why on my old gauge all it had was -1, 0 , and +1 and in the middle of the gauge it says X100KPA

have a look for your self .

that guage doesnt look stock / OEM

it loooks like a cheap knock off

ive never seen a guage show +1 to -1 KPA like that

are you sure its stock ?

yes its stock

my mate has an r34 and guess what its the same !!!!

maybe there different in the r33 (whitch you own NOT AN R34)

go onto ebay and type in r34 stock gauges and see what they are or better yet ask someone else on here who actualy has an r34 and see what they say !!!!.

mine has -1 to 1 in kg/square cm, which is pretty close to one atmosphere, which is 14.7psi. So when mine shows about 0.8 max boost, thats something like 12psi. Assuming its accurate.

Mine are pretty much the same as the pic above. They have a dark background tho, but maybe thats just the flash. It looks pretty similar in symbols etc to the dash

My R34 boost gauge is just like that, not like the one in the picture. Contrary to popular opinion, my one is also very accurate.

I have tested it against my PFC boost controller output on the hand controller, and on another mechanical gauge and they all read the same.

It is however very unreliable! It only works about 10% of the time!

yeah i thing the whit backgroung is because its a series 2 my mates is a darker background as well , but i was trying to point out to the know all its not a cheap ripoff its just that its in kpa not mmhg.

there must have been a change between the r33 and r34

yeah i was told its more acurate to put in psi because its easyer to get a psi reading instead of the conversions and guess work (as in if its .7 .8 or .9 kpa)

?!

Mines the same also, dark face, -1 to +1 and i have an 02 model. And it's accurate. Although it's been replaced by the nismo triple gauge cluster now, as it didn't read high enough.

    • Yea that's a fair assumption. I'm presuming they call them solid lifters as they have no moving parts like hydro lifters. 
    • I believe you're confusing WMI with water injection. Looking at that graph, the 93aki+WMI car is making more power than C16 race gas. Boost juice, which is what I also run, is Snow Performances 50/50 premix. 
    • GCG is a good company, they're a major distributor for Garrett in Japan as well.
    • Nah, OEM washer bottle and brake fluid reservoirs are fine I don't know what it is with the plastic that Mazda used, some plastics, like the washer bottle and brake fluid res are fine, and still look new after 20 years use, where as the coolant expansion tank, and PS reservoir, that I replaced with new OEM items when I first got the car, turned yellow and started getting brittle a few years later If the dirty yellow stained plastics didn't trigger me there wouldn't be an issue, but they did, much like the battery bracket....... Meh As for going back to work full time to support car stuff, nope, why, because I own a Mazda NC MX5, not a Nissan R series Skyline 🤣
    • I've never heard of CJ-motor, so can't advise you on them. I'd just go straight to GCG for a GCG highflow though. Seems no point to use a middleman. I'm somewhat surprised that the price on the CJ site is lower than the GCG retail price. Even though CJ would get a discount of some sort, you would hardly expect them to give up so much margin. Maybe the price is out of date? Having said that "I'd go to GCG"...when I did my highflow, I went to Hypergear. I did this https://hypergearturbos.com/product/rb25dethighflow/#tab-dyno-results with the R34 OP6 450HP profile. With the BB centre (extra $400) and intially with the standard boost actuator, but I eventually got him to send me the high pressure one when I got to the point of being able to actually use it. Ends up costing the same sort of money as the GCG highflow, but this is, of course, the turbo that I KNOW has a shorter length core and so moves the comp cover rearwards. The GCG apparently doesn't do that. My mechanic also swears by the GCG highflow, given that we have another turbo rebuilder who does something essentialy the same as theirs, using Garrett wheels. He says it stands up at really low revs and makes good power. I haven't pushed my HG highflow past ~240-250rwkW yet (should have a little more in it, but unclear how much) and it does have a fairly gentle boost ramp. OK, it's much better now that I have gotten my boost controller tuned up on it.  A lot of my earlier unhappiness was because I couldn't keep the wastegate flap as closed as it needed to be (including some mechanical issues). I'd still prefer it to boost up nearly as quickly as the stocker, and it certainly a bit slower than that. So maybe the GCG one is worth the first look (for you).
