So you have an aftermarket guage and factory one?

could be a few things, both wastegates stuck open (not sure why that would happen)

big boost leak (but then car should run rough as it will be running very rick when losing all the air after the afm)

if they are ceramic turbos the exhaust wheels could be shattered?

what mods std afm and computer system?

yeah an apexi and a stock guage

both needles dont move a bit no matter how you drive, and even at idle.

ive had a leak before and the car ran like shit and usualy stuff comes out the exhaust

they're n1 turbos and the boost has never been overboosted to a dangerous level

usual mods

cooler

ebc

im just stuck to understand why the guages sit at 0..

well then have u checked where the guages are connected? if they read zero at idel something definatly wrong. are they plumbed in independantly?

you will have vacume at idel, if the guages have disconnected then they see atmospheric pressure and stay at 0 at all times.

i'll go check again now, but they all end up in the same spot near the firewall drivers side.

    • Man, different parts but the same numbers is terrible @dbm7! And it doesn't help that most online shops don't list the part numbers at all. They just give a list of compatible models...
    • Slow when hot could also be because its getting more dynamic compression, OR things are getting a bit tighter once it is all expanded. If it were an earthing issue, typically I'd expect you to have it have issues all the time. Unless it's really a combination of both things. Where the higher compression, and things being a bit tighter, is giving that bit of extra load and you do need a slight clean up on the cables/connections.
    • Yeah, this is one of the most annoying things about nissan part numbers... I've got an unrelated example... Image is of the AT output shaft ~ they have the same part#, but clearly the shaft on the left is beefier design to that on the right ...the difference (essentially) is the 'lighter' shaft on the right, is for engines up to RB25DE (this includes RB20 variants) : the shaft on the left is for RB25/26DET(T)....are they interchangeable? Yes...but obviously one shaft is going to be stronger than the other...and, the lighter shaft is around USD115, but the heavier shaft closer to USD150...same part#... ...epc-data usually tells a tale ~ the amayama listing for 39100-23U60 has a note "Longest side is between 60 and 105 cm" ; no such info is there for 39100-23U70 ...and given the great disparity in price between the 2 parts, it makes me at least curious (to the point of caution) where the 'extra money' went? ...ie; these 2 parts have a cost difference that (to myself at least) isn't explained by 'plastic boot'...ie; with amayama there's AUD700 price difference ...plastic versus rubber?...I'm not seeing it like that...and 60cm ~ 105cm...??...that's a huge disparity....something hinky going on here... I'd try searching by VIN, not model... /2cents
    • I don't know for sure, but I'd expect them all to be interchangeable given the diff end and hub end don't move/change between any C34 series. Often Nissan will change part numbers and the aftermarket follows those year ranges; but the original part number change doesn't mean other parts won't fit. The change could be a change in material, internal parts or even just supplier. For example, all the RB gearbox to engine bolts are no longer available and there is a new part number instead. The only change is they went from cadmium plated bolts to zinc plated due to the issues manufacturing with Cadmium. They look different but work the same.
    • One year is a bit concerning. Did you try contacting GSP? It says 5 year warranty on the box if I remember correctly. I'm also running their driveshafts on my S2 Stagea.   You could check the part numbers on Amayama for your year. Here's the link for my 1998 which gives the 39100-23U60 part number. Well, that and 39100-23U70. https://www.amayama.com/en/genuine-catalogs/epc/nissan-japan/stagea/wgnc34/6649-rb25det/trans/391 What does it say for yours?
