Im just posting this up while it flashed in my memory. Subaru wrx's run R160 and R180 diffs.

The R160 is found in wrx impreza's and the R180 is found in wrx sti's. I know the sti version is definately lsd.

im not sure about the R160's if they are lsd but they might be. They share same bolt patterns and everything!!

Anyway, thought some of you might find it interesting, if you didnt know it already.

The problem with this is that the Subarus use a different diff centre. The Datsun/Nissan halfshafts don't fit. You would need to have someone make up some custom/hybrid halfshafts that use Subaru splines for the diff and use the Nissan parts that bolt to the companion flanges (wheel end). Not a cheap exercise.

i realise its not a cheap exercise but i just thought that maybe someone changing their diff or upgrading or whatever,

they can be aware that these R series diffs come in cars other than nissans. I got stuffed around making up halfshafts for my car, and thought that other people might have the same problem and maybe be able to do some mods like this. I know it probably would have worked out cheaper for me!

Last time i take anything to someone that doesnt know what they are doing...

I wish I had read this a week ago before I bid on a Subi diff centre on ebay... bummer.

has a HEAP of info there, about 3 pages!

ALSO

my mate from tassie WogsRus (his username)

he sent his R180 diff to get rebuilt into LSD spec, and the workshop used Subi Liberty parts and it worked really well... was in a R30 sedan (it was about 5 years ago too, so this cars probably history now...)

there seems to be so many options concerning these R series diffs that i am sure a lot of people are unaware of.

There are not a lot of people that specialise in these parts, thats what i have found anyway.

      Upgrade an rb25neo

      By Tekitsune · Posted

      Hello, just just bought an 1999 enr34 with a stock rb25neo and I'm looking to upgrade the engine to 500whp I know some basic things but wondering if there are things I'll need to do to upgrade the stock block and all the bits and pieces to achieve this.

      Rear subframe stay bracket bolt removal issues

      By DatsunBanana · Posted

      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 😅

      Question about BoV on RB25DET NEO

      By Dose Pipe Sutututu · Posted

      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 🫠

      Question about BoV on RB25DET NEO

      By Yeetus · Posted

      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...
