Just ran my first full tank through the Stagea since I fitted the 26. Got 490kms on 56L which included mostly open road (with a fair bit of WOT) but a bit of round town driving aswell. Interestingly I only got 200kms out of the first half.
I'm just about to fill up again with the km's sitting on 420km with mostly round town driving & one hour long open road trip. I must say I'm actually quite pleasantly surprised.

I think sydneykid has mentioned it before, the Walbro needs 13 + volts to perform at 255l/hr
You may only be getting 11 volts and therefore your pump is not pumping enough fuel for your thirsty rb26
Try this mod
Ahhh I see. That makes sense.
I had considered hard wiring the pump with a direct feed from the battery but my concern is of the safety side of it; I don't want it to keep pumping fuel if I ever crash it (well if someone crashes into me
) -
Ok, not sure if this is a subject covered before but I'd thought I'd bring it up.
People talk about fitting a fuel pump to their Stagea but I haven't ever seen any detail about it.
I currently have a Walbro 255 in the tank behind the 26 but to be honest its not right. It won't run right when its cold (like its starving of fuel) & if you thrash it it doesn't seem to catch up for a while. Talking to a fuel pump expert he said that some Nissans (Z32 300ZX for example) run variable rate earths at the ECU & that may be what is causing my problem. I personally have a re-shelled 260RS if that makes any difference (including the entire 260RS wiring loom) so I'm just curious as to whether anyone has had fuel pump problems with their Stagea/260RS.
I have access to a Bosch 044 with a the appropriate fittings to adapt to the Nissan setup but have been told (by the same guy) that I will at the very least need to change my fuel pump relay for fear of burning it (or the wiring/ECU) out. Of course I haven't wanted to risk a 260RS ECU so haven't taken it any further.
I'd like to wind the boost up to 1 bar but I don't want to risk a lean out with a sketchy pump so I'm holding back at the moment but I can tell you my RH foot is getting itchy.
What are other people running in their Stagea/GTS25T/GTR etc etc?
On a similiar note; how do people wire up secondary fuel pumps? Into the same earthing point (via the ECU)?
-
using the standard radiator mount was fine, they had to cut some metal out of the support to fit the headlights, make up some custom headlight mounts out of fibreglass and move the bonnet catch forward
Ok thats not too bad then.
Where did you get your guards from? Are they MASA items?
-
I dont know if it was a r32 or 33 gts4 before anyone asks lol.
A RHR R32 GTS4 axle fits the LHR of the Stagea with perfection. Don't use the LHR GTS4 (like I did at first) as looks like it will work & it does fit but the first time you squat the rear end with a fast take off the output flange walks out of the diff
I used a 260RS axle for the RHR. -
How did you get on with using the standard rad support? Any dramas fitting the stuff up? ie the headlights
-
All sorted.
* RS-Four hub carriers with 260RS (or GTR or R32 GTS4) hubs fitted hence enabling me to use my RS-Four adjustable coilovers
* R32 GTS4 LH Axle in the LHR (unmodified)
* R34 GT-T RHR Axle with 260RS ends
Anyone would be able to recreate what I've done easily enough apart from needing a 260RS axle of course
-
Just so everyone knows; 260RS axle are not the same as GTR in either thickness (including splines) or length. They are the same diameter & spline count as R34 GT-T though.
MY RH axle is done using a combination of a RH GT-T axle & 260RS diff end & I am getting a GT-T CV modified to fit onto a R32 GTS-4 LHR axle as I write this. Hopefully should be done in a week or two as the guy is pretty busy.
-
Just out of interest I thought I'd share this; from top to bottom;
RS Four LHR Axle
260RS LHR Axle
R34 GT-T LHR Axle
Hopefully when my R32 GTS4 axle turns up this morning I'll be all set
-
Stagea is smaller than gtr unless you have a rs four s or autech which are the same as the GTR
Well I have an Autech axle & its 90mm but trying to confirm that it IS the same size as GTR as a 90mm is what I need
-
errr
let me rephrase then
for people that took the front driveshaft out, and need a diff...lol
:laughing-smiley-014: Sweet as.
Saturday went 90% as planned but I'm still short a LH axle. Just trying to figure it out at the moment. Unfortunately thats what happens sometimes when you make assumptions
-
im using a gts4 one on my car now im 99.5% sure thats what its from, and they are the same as gtr ones, only the stagea ones are the smaller ones from what ive seen.
Thanks. Can anyone confirm?
-
well i got a 32 gtr axle here without the end u need but the rubber boot measures 105mm or so, so i'd say 100mm
Buggar.....................thanks bro. Anyone got a GTS4 they can check?
-
Trying to get my Stagea sorted (pretty keen to race it at Dragwars this coming Friday) but run into a small problem with my LHR axle.
Can anyone tell me the outer diameter of an R32 GTS4/R32 or R33 GTR axle cup? It should be either 90mm or 100mm. (see pic). Its the part that bolts to the Diff outout flange.
This is the make or break moment for my rear end setup. Its all back in & bled up just missing a LH axle. Help :confused:
Thanks in advance!!!!!
Sorry about the crap photos.......................
-
im just trying to say there is more than one option
gtr
gtr is hte LAST option id do mainly becuase of hte cost
you can get an r200 and shim it and get great traction(or loss of it, whatever your desire)
I understand. If anyone else were to do it (and not start with a GTR diff like I did) then yes there are definitely more options. It is difficult finding a 4.11 ratio to match the GTR front diff though.
-
If I was it upgrade my RS4 diff and driveshafts, what parts do I use?
Will let you know on Sunday Darrin. I'm fitting it all back in on Saturday
-
So what is the final parts needed?
Diff?
Output shafts?
LH and RH axles?
Anything else?
For me personally? CV grease & LSD oil. Otherwise I'm not quite sure I understand the question Darrin...............
EDIT : Sorry, I just read further up the thread. I'm fitting it all on Saturday so provided I don't run into anymore issues I'll post the full diff swap with pics on Sunday
-
you guys are crazy with your GTR setups
SIMPLE solution
S13/14/15/y33/y32/gtst/r32/r33/
all the diffs are interchangable
Yup, I know. I work for a Nissan dismantler
you might not have mounts for the attessa shit, but you can make themI have an s13, with WGNC34 rear cover, s14 solid diff mounts, and Nismo 2 way
swap the input shaft for the driveshaft from teh C34 to the s13 diff, bolt that ish up
throw some greddy or veruspeed gear oil in there and your good to go guys.
just make sure you get the output shafts wit hhte same number of bolts (6 i think?)
Yeah but in the end it seemed crazy for me to buy another diff (I'd already bought 2 others) when I had 80% of a GTR diff already. The flange only cost me $300 & now it bolts straight in and includes the mount for the ATTESSA pump. The axles were easy (don't believe what people tell you) and I get to have a mechanical LSD as opposed to Viscous
-
Here it is :
Will fill you in on the axle/diff situation after the weekend but should be all good
-
Well I have it all sorted now, my R33 GTR RH Output flange is on its way from Japan.
On top of that I sorted my axles and I don't need to change my hubs to GTR/260RS spec either. In case your wondering, no I am not going to use my piddly RS-Four axles nor am I using axle/diff adapters.
It was (in the end) all very easy. If anyone is interested I'll update with photos when my Output flange arrives in 2 weeks.
-
Dammit. I meant to say output shafts the same, not the axle shafts... My bad, sorry.
Oh ok, so I need R33 GTR output flanges then, thanks for that
EDIT : I can confirm that yes they have the same part number. Cheers Psy
On the subject of R33 GTR. Can I use this :
Its an active differential. These apparently came out in some R33 GTS25T's aswell. Has anyone ever retro-fitted one of these to there Skyline/Cefiro etc. Can anyone forsee any problem?
-
Ive smashed my front diff (rear is still good) so you might want to look at that too.
I'm already running the 260RS front diff, hence why I need to change the rear to match it.
R32 GTR output flange is close enough that I could probably use it. On a whim seeing as they are also R230 I tracked down some 300ZX TT output flanges to compare against, as you can see they're quite a bit different again
-
260RS diff is R33 GTR diff. So are the axles.
The only R33 GTR diff I had to compare against was an Active Differential type (which was definitely different) so you could well be right. To be honest I had always assumed that 260RS was R33 GTR but I suppose R32/R33 output flanges could be the same.
-
Change to a GTR diff and axels. You going to have to at some stage man. Might as well get it over and done with.
Well it appears 260RS is essentially R32 GTR anyway so I should be alright. I hear what your saying though, thanks
)
I used a 260RS axle for the RHR.

Definitely better than the 25DET I had in it before. Was lucky to get 450km to a tank of casual driving on the open road. Even after I converted it to manual it wasn't really any better (but that could have been my right foot :laughing-smiley-014: )
I honestly believe that if I drove a full tank nicely I could get 525 - 550km's. Watch this space
