Hi there, have an s15 3.69 long nose abs diff in my r34 and would like to go to a 4.11 and 5 bolt shafts

Does anyone know if pinion and crown wheels from a NON abs diff (short nose) will fit inside the abs (long nose) diff?

Ring & pinions are not interchangeable between long and short nose. Pinion is longer in a long nose diff. Cheers. 

How did you get a S15 diff to fit in your R34? I understand in a R33 with ABS but doesn't make sense as the diff is the same length as a R33 non ABS. R34 has 2x ABS rings and sensors on the output flange where as a S15 or R33 has the ABS sensor on the diff input flange area.

Pov spec R34s (ie, without turbo), and in particular auto ones (I think) have that silly diff with the slightly longer nose with the speed sensor on the side of the nose. I'm not even sure that it's an ABS sensor. I think it's actually the VSS sender. Anyway, it's not an S15 diff, it's whatever was jammed into the stupid things.

Nope, the R34 Non-turbos have literal S15 parts for their subframe, axles, diff, diff internals, and ABS system (including the ABS ECU and wiring/pinouts)

The non turbo part is where the difference is.

It's just one of those bugbears that I bring over from Facebook. Lots of people think the dividing line between them is Sedan vs Coupe or Manual vs Auto for some/any feature but it's always NA vs Turbo (or GTV).

I have no idea if GTV got the GTT rear end. I'm just gonna pretend I know and say "yes they did"

And you'd be correct. The GTV got the viscous LSD (I'm pretty sure they didn't get any helicals) and the same fork shock connection as the GTT and GTR. For all intents and purposes it's a non-turbo GTT.

My car was originally an na auto GTV hence it has the abs sensor at the front of the diff. Previous owner swapped the diff out for an s15 3.69

You would be correct. It is "technically" an abs sensor but it is used for vehicle speed to the na dash cluster

Correct. They came with a viscous lsd or open diff with the sensor in the nose of the diff. Brakes from a GTT, shocks and hicas from GTT as well. Only thing drivetrain related that isnt GTT is the diff and gearbox which would be all na stuff

learn something everyday!

In that case you would be better off just getting a R33 GTS-t diff, 5 bolt stubs and shafts. Similar to what the S15 guys do, at the same time put in a proper LSD centre as the viscous centre is junk.

yep thats the plan now. only problem is theyre impossible to find. I wanted to see if the crown and pinion from a non abs would fit cause those are a dime a dozen. There's a guy selling a non abs 4.11 with axles and a 2 way for cheap as f**k but wont suit my car unfortunately :(. Just gotta stay on the hunt for an abs diff and axles when they do pop up. For now just gonna rebuild my 6 bolt axles and take it easy on the car until i can get a new diff and axles

Is it a S15 helical diff? if so they're decent.

Just a few idiosyncrasies to deal with when going up driveways when 1x wheel is off the ground, etc.

it is indeed a helical. it feels nice on the road but the ratio is way too long for me and I like to drift the car. I need a proper lsd and stronger axles for the amount of abuse this thing gets ahahaha. Also doesn't help that im a stance boi that has air suspension so my car is sacked to the ground. Diff always one wheel peels when im going up my driveway which is annoying as f**k

Use the handbrake to load it up!

Could try a S15 Auto LSD, brings it to a 3.9

Tried that ahahah, thats what broke my inner cv joint. Handbrake + clutch kick and then broke the cv joint bearing

Sounds like an issue with the car's height than anything else.

The car itself when driving doesn't sit too low. Front bumper is probably 80mm off the ground but chassis rails and everything else sits at least 120mm off the ground. Could possibly be the alignment settings I have now are pulling the axles out of the diff/hubs a bit but its all basically factory specs

    • Thanks everyone for the replies and suggestions. Got the seats out (hoping I could find some existing grommets but no such luck). By tapping and measuring etc. I could figure out where I could drill through if needed. But first I borrowed an inspection camera and managed to go through factory holes in the chassis rail and could see that the captive nut was holding steady which is why it could retighten. So it was indeed a stripped section of thread, so I applied downforce by levering the bolt head with a screwdriver and went slowly back and forth until it came out. Camera helped a lot cos I could monitor that the captive nut was holding tight. Now I just have one very seized main subframe nut to tackle 馃槄
    • BOVs do have a purpose, if you ever log pressure before and after the throttle body, you will see a spike pre throttle on lift off from a WOT condition. Enough to bend throttle blades / damage e-throttle motors or simple assist in blowing off cooler pipes. FWIW, the above on really applies to those running at least 2 bar of boost. OP shouldn't have an issue, on the other hand, here are some videos of my shit box over a decade ago with some succulent dose with the airbox on and off. That shit box is unrecognisable these days 馃珷    
    • I've tried all different combinations of BOVs/ no BOV and stock bypass valves over the years, on gear changes the stock bypass valve seems to get the car back on boost quicker because in part the turbos wheel speed isn't being slowed down by reversion, although they have issues holding boost much over the stock setting. Most aftermarket BOVs you can adjust the spring, tighter will make it open later and close sooner, but in my experience it'll cause a bit of flutter at low load/rpm anyway. I've also got some input into this whole no bov causing turbo wear, never had an issue on any on my turbos HOWEVER, I got my R33 GTST with 200k kms on it, with from what I can see still has the original turbo, no lateral shaft play but has about 4-5mm of play in and out which to me seems like a worn thrust bearing from years (100-150k kms?) of turbo flutter running no bov, so maybe there is some truth to it in the long run. But that'll never stop me loving the Stutututu while I have the car.   OP just wants to know if he can run a atmo vented BOV with no major issues and the answer is YES, plenty of people do it, there's no harm in installing it and seeing how it runs before spending $$$ on an aftermarket ecu, last time I bought a Nistune it was $2400 for install and a tune , unsure of todays prices but you get me. Crazy money to spend just to fix the minor inconvenience of stalling that can be overcome by letting the revs come down to near idle before putting the clutch in or a little bit of throttle to avoid it. You're better off leaving the ecu and tune for after a bigger turbo/injectors have been installed to take full advantage of the tune and get your moneys worth.   Let OP have his Whoosh sound without trying to break his bank haha
    • I see you missed the rest of the conversation where they have benefits, but nothing to do with avoiding breaking turbos, which is what the aftermarket BOV made all the fan boys, tuners, and modders believe was the only purpose for them...
    • But they do so for the other reasons to have a compressor bypass. It's in the name.
