having a problem with my car lately, it doesn't happen all the time its just happened to me twice. I think it might be boost spiking. When I'm on 4th gear boost kicks in at 4.500rpm it starts pulling and then all of the sudden its like the car downshifts and over revs. I'm starting to freakout, I'm leading it to boost spike but I need to be sure, I need your opinions to what it might be? like I've said just started to happen recently, mainly in cold nights. I've had all the mods done around a year ago and was working fine. I told my tuner if I needed boost controller and he goes its fine as long as its set to 16psi

do you have a boost gauge? that will tell you whether you are getting a boost spike or not. if the boost pressure increases then you have a boost spike. if it stays the same there is no boost spike.

when you say it's like it downshifts and over revs, do you mean it sounds like it's hitting a rev limiter? so in other words, the car is misfiring? if yes, then it is most likely your coils are on the way out, or possibly the spark plugs.

I don't know I've changed the clutch 2 years ago, but it sounds like the same problems before I got the new clutch put in, surely the clutch that's gone. I don't drive the thing hard. But damn its like I hit power and then the car goes to neutral and revs like crazy. only happens on 4th gear.

      Stagea Front CV Axle Question

      By Duncan · Posted

      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.

      Stagea Front CV Axle Question

      By soviet_merlin · Posted

      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?

      Stagea Front CV Axle Question

      By S1_C34 · Posted

      I ordered a GSP Front R/H Axle from here - https://justjap.com/products/gsp-premium-front-driveshaft-r-h-nissan-r32-r33-r34-skyline-gtr-stagea-4wd#description It lasted around a year before one of the boots blew out. I'm lowered, but I have GKTech roll center adjusters. One year seems a little premature. I think I'm going to spend the extra money on an OEM cv axle this time. This website - https://tfaspeed.com/collections/nissan-stagea-wgnc34-x-four-parts/products/nissan-stagea-awc34-260rs-rb26-right-front-axle-drive-assembly Makes it sound like the readily available OEM CV axle will only fit 11.1999 Stagea and up (mine is a 2.1997 S1). The JustJap listing didn't mention any years or anything for the GSP axle. Amayama shows '11.1999' and up as well for that part number. As well as 'plastic boot type'. See attached picture. So I guess my question is, does that axle (39100-23U60) really only fit S2 Stagea? It's the front driver side. If it does, I'd love to buy that instead of rolling the dice on another GSP. I've found that OEM one cheaper here: https://www.partsfornissans.com/oem-parts/nismo-jdm-r32-r33-r34-skyline-gtr-r32-gts4-right-front-axle-3910023u60 and here https://www.nissanparts.cc/oem-parts/nismo-shaft-ft-drive-3910023u60 Just a little confused because the JapSpeed listing for the GSP front driver axle doesn't mention any specific years or anything and it fit my S1 Stagea fine. So will 39100-23U60 fit my S1 Stagea even though technically it says '11.1999' and up? What would have changed? Thanks.

      CD009 RB Conversion

      Thanks for the info. The only "Issue" I've had with the shifter is I always found the throw between 4th and 6th gear too close. I'm always worried to shift into 4th accidently and sending my motor to the moon. Adam LZ recently came out with a video and stated Serialnine revised their shifters to correct this and will change all the revised parts for 150$. Strangely enough, I contacted Serialnine right after and they denied it and said it's bullshit. I found that strange as he's a distributer. I'll keep this forum post updated on that saga.

      Yep that is correct. It allows you to adjust the short throw range from what I can tell
