R33 GT-R Active LSD removal - What to do with the hoses?

Hi guys, searched all of the topics but can't find anything about what people do with the hydraulic hoses when removing the Active LSD from an R33 GT-R (or factory optioned GTS-T)?

My thoughts would be just to replace the banjo fitting with a "blank" which could be machined up or just whack an AN outlet banjo on it and whack a cap on it.

Banjos & Bolts - Fittings & Adapters - Brake Hose, Fittings & Accessories

 

Has anyone done the removal and have any tips on how they went about it?

Thanks.

EDIT - I did find these photos from R31Nismoid (had plenty of keyboard warrior battles with him over the years...) where he did it and looks like just banjo blanks blocking it off-

Will look into that a bit more when I go to do the change over.

Can't imagine you'd have a problem with capping the hydraulic output line on the actuator block for the A-LSD as long as the solenoid isn't trying to actuate and send a bunch of pressure through the line to test just how leak-proof the threads on your blanking cap really is. I get the impression that the pump is a common pressure source for both the diff and the transfercase so I presume the solenoid is what controls how much pressure the diff/transfer actually sees.

Yeah the way I look at it, it shouldn't cause dramas to block it as the system is designed to hold a high amount of pressure once the diff has been "active"-ated.  It's a high pressure activated system so it really shouldn't make a difference whether the pressure limit is reached at the fitting on the pump when blocked off or in the hose that attaches to the diff to activate it under normal circumstances.

Shoota, I assume you are replacing your A-LSD with a mech LSD?  If so, what mech LSD are you using?  I want to replace my A-LSD with a mech LSD but seems there is nothing aftermarket available.

Good to see your build is progressing.

Hi mate, yep putting in a mechanical LSD out of a non V-Spec.  I really don't think there is any other options other than what came with the vehicles which is pretty surprising.  Surely someone can make a custom one that is relatively affordable?  The genuine mechanical LSD's are worth a fortune nowadays so glad I have one...  The one I bought 8 or 9 years ago the guy thought it was stuffed so I only paid about $200 for it.  I had it checked over and reco'd by my diff guy and he said it's perfect! 

Yeah the build is VERY slowly progressing but slowly is better than not at all I guess! 😁

      I mean, I got two VASS engineers to refuse to cert my own coilovers stating those very laws. Appendix B makes it pretty clear what it considers 'Variable Suspension' to be. In my lived experience they can't certify something that isn't actually in the list as something that requires certification. In the VASS engineering checklist they have to complete (LS3/NCOP11) and sign on there is nothing there. All the references inside NCOP11 state that if it's variable by the driver that height needs to maintain 100mm while the car is in motion. It states the car is lowered lowering blocks and other types of things are acceptable. Dialling out a shock is about as 'user adjustable' as changing any other suspension component lol. I wanted to have it signed off to dissuade HWP and RWC testers to state the suspension is legal to avoid having this discussion with them. The real problem is that Police and RWC/Pink/Blue slip people will say it needs engineering, and the engineers will state it doesn't need engineering. It is hugely irritating when aforementioned people get all "i know the rules mate feck off" when they don't, and the actual engineers are pleasant as all hell and do know the rules. Cars failing RWC for things that aren't listed in the RWC requirements is another thing here entirely!

      Best place to order Authetic R32 Parts in Japan

      By GTSBoy · Posted

      I don't. I mean, mine's not a GTR, but it is a 32 with a lot of GTR stuff on it. But regardless, I typically buy from local suppliers. Getting stuff from Japan is seldom worth the pain. Buying from RHDJapan usually ends up in the final total of your basket being about double what you thought it would be, after all the bullshit fees and such are added on.

      Ethanol Content Sensor - Always at 11%?

      By GTSBoy · Posted

      The hydrocarbon component of E10 can be shittier, and is in fact, shittier, than that used in normal 91RON fuel. That's because the octane boost provided by the ethanol allows them to use stuff that doesn't make the grade without the help. The 1c/L saving typically available on E10 is going to be massively overridden by the increased consumption caused by the ethanol and the crappier HC (ie the HCs will be less dense, meaning that there will definitely be less energy per unit volume than for more dense HCs). That is one of the reasons why P98 will return better fuel consumption than 91 does, even with the ignition timing completely fixed. There is more energy per unit volume because the HCs used in 98 are higher density than in the lawnmower fuel.

      No, I'd suggest that that is the checklist for pneumatic/hydraulic adjustable systems. I would say, based on my years of reading and complying with Australian Standards and similar regulations, that the narrow interpretation of Clause 3.2 b would be the preferred/expected/intended one, by the author, and those using the standard. Wishful thinking need not apply.
