soldering iron and solder obviously. scratch as much of that crap of and clean it up before starting. try to get the joints hot quickly and either shake it to flick out old solder or just add to it depending on what it looks like. try not to get too hot as diodes and other components will break down and fail. sharp knife or scewdriver when you finish and scratch a line between the tracks on the board incase any residue has settled between them. goodluck

The three main bits with the orange around them are the usual culprits for dry joints - you shouldn't even need more solder - just clean up the gunk, then heat them up with an iron to re-flow, and should be good. The orange is a good indicator of an issue with the joint. I re-flowed those three joints on mine (only ones showing issues) when the gauge was starting to play up on occasion (usually going over bumps), and it's been perfect since.

If you see any others that look dry - might be worth cleaning up & re-flowing those too.

Is the hose still intact from the plenum? One of the times my gauge failed, I found the hosing split to pieces, barely noticeable - but it just sat on 0 (or just off). I think they fall to pieces after a few years in a hot engine bay - it was terribly brittle.

I pulled it off the sensor and started up, the suction was defiantly there, didnt see any cracks or splits...but will mulit check it.

Edit: Hose is clean and not cracks or holes that i could see..

Does it matter if i have an after market boost gauge on / will that effect if the stock boost is working ?

Aftermarket gauge will typically be hooked up to a different point, so should be fine. As long as the piping from the plenum is going into the boost sensor, and the sensor is plugged in fine, should be good. You could also try reading the voltages out of the boost gauge - the R34 service manual lists what voltages associate with what boost levels (will rule out whether it's sensor or gauge failure)

I'd offer to drop past and let you try out my boost sensor, but the front end of my car is in pieces at the moment for fitting FMIC and not sure it's gonna be driving for another week or so... (depends how lazy I am)

Try borrow a boost sensor some wreckers will let you try to buy. Or you could blow into the sensor with a hose and watch the guage. I had to wiggle the plug on the boost sensor all the time to get it to work until i re soldered. The pins could be dirty where it plugs in. It sounds like its trying to work. The guage wouldnt even move if it wasnt for the sensor sending something.

Thanks for the offer Jenna, I read your FMIC didnt fit which sucks.

I found the after market boost is hooked up via the BOV so that didnt affect it at all. I went to Andrew's (nightcrawler) last night and picked up his spare triple gauge. Put it in and seems to be working, but only quickly tested it. Looking at the back of the Nismo one there are a few orange solders so i will go over them today and see what happens.

As for the sensor anyone know if the r33 and r34 use the same one ? I read on a couple post people using r33 sensors and they seem to work the same, anyone confirm?

      Stagea Front CV Axle Question

      By soviet_merlin · Posted

      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.

      Stagea Front CV Axle Question

      By dbm7 · Posted

      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?
