why on earth would you? I'm not diff welding expert but I imagine it will be tricking as the GTR centre is a mechanical clutch pack type LSD. if you want a welded diff at least sell your GTR centre and get a crap GTST diff, weld that and put it in.

So a GTSt centre fits in a GTR housing? Or you mean the whole diff as one? What about the ATESSA pump mountings?

You would do this because youre low on money and need some traction at the rear! Im not saying its the best idea, but does the job?

you can run a gtst centre in a gtr housing no problems. You can't really change to the gtst housing in a gtr as it wil change your rear diff ratio (but not the front diff) so attessa will go all sad.

but you really should just shim up the standard one, you can get it as tight as you like without the disadvantages of a welded diff. under 300 to shim and adjust the stocker

early 32 GTR centres are worth next to nothing and Nismo shim kits are about $200...best way to go.

PM me if you want one with kit fitted ready to install.

later R32 centres on the other hand are expensive, much sought after and rare.

I thought f**k it, I went crazy and I got myself some 1.49 shims (LOL theyre hardcore thickest ones!) from Nissan, came next day. $6 bucks each!

Im going to chuck them in this week, will post results :)

Hopefully an insane amount of lock, I just didnt want a welded diff to wreck me suspensions...got a feeling it will be very close-to though.

if you really shim it up, it shoudlnt be as bad as a locked diff, but will still churp quite often on tight bends.

that said i dont see locked diffs as 'bad', infact my minispool was the best $100 i ever spent on my car :)

What is the difference? and how do you tell them apart?

what if you just buy a lock diff, i got one in mine, took me ages to find out why my car was always clunking/tyre skipping sound, when turning, the car already had the lock diff in it when i got it

Any one welded up a R32 GTR diff at all - open enough to get a bead in there?

Are you sure you don't just have a very tight diff? They will act like this around most corners.

What happens if you put the clutch in or neutral, and take a corner pretty slow? Same locking on the corner?

Guys please remember this request for diff lock or full spool is for drag application only and i simply want to lock the back diff up to keep her straight as posoble - i have no attesa or hicas etc - all gone - do have to make a choice still have done as yet.

Have engaged an engineering entity that says that bthey willl send me a proto type full spool but sadly have been waiting a very long time - have my doubts wether will come good .

need suggestions lads got to do in next few weeks - any one know where i can get a full spool.

Any examples that you know of with big HP with shimmed up tight rear diff - results ??

      Low oil pressure after WOT

      Don't turn down the limit yet. Put a mechanical pressure gauge on the car in the same spot and go and prove it.

      I've done a few BMS systems. Code in Canada use to force us to have any safety components outside of the PLC but with a code change back in 2018 I believe it was, we can now use safety PLC's to control everything. Sadly to your point, AB Guardlogix safety instructions for example are only available in ladder.  Machine safety is a very big thing here though, you're constantly forced to migrate to the next best thing by OSHA. I honestly prefer safety plc's, including anything from AB more then I do working with old school safety monitoring relays. PLC is only one portion of it, the rest of the electrical still has to follow to meet SIL (Mechanically linked dual contacts, bla bla)  Now tell me how to feel about safety over comm's (e.g Ethernet/IP CIP) on a unmaintained network haha

      To your point, boolean logic. We're not only working with bools in ecu's, so it's very limiting. I wanted to setup a low WMI pressure alarm. After 1 second I want WMI line to hit 100PSI, 2 seconds 175PSI, etc. and trigger an alarm if it doesn't meet those thresholds. This would of taken me one very short line of text, but instead I had to bugger around with generic timers, conditions, etc. and so forth.

      By pogman · Posted

      I much prefer that to an actual oil pressure issue, never would of thought it would of been a volt drop issue but SAU brains win again. Guess ill be turning down the oil pressure limit for the track and hunting some grounds. Ill hopefully update this thread with some high oil pressure and solid ecu voltage logs.

      Question about BoV on RB25DET NEO

      By Murray_Calavera · Posted

      You've just discovered a really good reason to tell yourself, yes, I do need to buy an aftermarket ECU. Put the MAF in the bin. Slap in the new ECU and have a think about what turbo sounds you prefer.  Do you want a 90's style BOV wooosh? Do you want a hektik tsututututu?  Mate, can't go wrong. Just gotta get that ECU and the world is your oyster.
