no you dont need r33 axles, i'm running gtst r33 axles in my daily cefiro with the s13/r32/a31 type subframe in there so they should contract and expand to suit, which is just what they do if you have a spare set laying around to look at.

r32 LCA's are slightly shorter and the bushes are slightly thinner then r33 so that might be why its suggested also the camber arms line up the same they just might be slightly longer as i have a few spare sets laying around that i compared.

the r32 tie rod could be shorter and the hicas may not mount up to the same hole so i'm unsure those issuses

Why would you do that instead of typing it into Google?

whats the benefits vs cost in this perspective? in the near future i will be looking at getting power to the ground tho im sure that offset bushes and a decent suspension will be just as good aslong

If it comes with diff and shafts then I will take it. I have a crade but its a V-Spec and trying to find an R33 diff and shafts

^Thanks, mate. That was the last bit of information I needed.

I haven't yet installed the R33 subframe but it looks like I just need the items I previously mentioned and I can still retain my BNR32 axles.

I'm going to uninstall the HICAS at that time so I just need to figure out if I can use a HICAS lock out bar designed for the BCNR33. I imagine that BCNR33 lock out bars will suit me better than ones designed for the BNR32.

Don't use a HICAS lockout bar. Get one of the kits that pisses the HICAS rack off (and doesn't replace it with a bar) and instead adds some brackets to mount some new toe arms to completely get rid of the old tie rods. The tie rods are half the problem with old HICAS rear ends. They get sloppy. Why keep that crap in the car when you can get rid of it.

I went the whole hog and put a non-HICAS subframe into my R32 (GTSt) rather than have anything non-factory back there. That's because technically any HICAS removal/locokut is modification of a steering system and must be engineered or it is defectable.

My car just went through Regency like this for the engine conversion and the inspector (who knows Nissans fairly well because he's probably been under 50% of the S13s and R32/3s in Adelaide!!) did not even blink.

Thanks for the advice. You're non HICAS subframe is definitely non factory back there.

I'm changing the engineering of the rear anyways per the use of a different subframe. I doubt installing a HICAS lock bar.. Bars will cause more major geometry changes than I will already have.

Btw, I'm using SPL Hicas lock bars as opposed to a long bar.

No....my non-HICAS subframe is from a Cefiro but is exactly the same as a non-HICAS R32 subframe. There were plenty such cars made, just not as GTSts. So it is definitely factory. Factory subframe, factory toe rods. Unless you 100% were expecting to find HICAS under there, you wouldn't even blink. But the SPL bars look non-factory even though they approximate the same design as a proper non-HICAS subframe. If they are brightly coloured, paint them black before you fit them.

I don't worry about the geometry changes and so on that result from mods (unless they are undesirable changes from poorly thought through mods!! But let's assume that we're talking about intended geometry changes). I do worry about keeping it looking stock enough that no cop will bend down and jump for defect glory joy if he gets a hard on for me.

yes non hicas frames came from nissan and the a31/r32/s13 frames are all the same except for an extra exhaust mount on the s13.

gtr cradles are ment to have some extra bracing but nothing special as that can be welded to the others.

i'm just going to make up a mount out of plate and weld it in for the hicas r33 cradle i have for my non hicas ceffy.

edit: in fact s15 cradles are said to be the same as the r33 but the s15 were all non hicas

My point, and maybe I see things differently, was that a rear subframe other than stock is not "factory."

Great, yeah, its from another Nissan vehicle. Perhaps, that's "factory" according Aussie laws.

A subframe from another make could have hypothetically fit on there and been "factory" for that specific make. For example, lets say that a Ferrari subframe fit on there from the Ferrari factory.

Anyways, I get the point. I love the idea of not having to use hicas lock bars if not needed. I've been told that the R33, S14, S15 are basically the same.

I had mine done a while ago, Brad/Risking did it for me just before I busted my engine so I cant tell you how much better it makes the car..

didn't end up costing me that much in the end, I did it as an upgrade while I was changing my subframe and diff bushes.

How did you manage to fit the 33 frame to the 33?

When the 33 frame is fitted what suspension and brakes will be used??

When u want to fit after market parts how do you go about that ??

      Fark what are the changes of that snapping like that, clean. Nek minnit, custom radiator goes in, with built in oil cooler like those discontinued PWR ones from yesterdeacades ago

      7 Speed Auto transmission fluid change (Skyline, Q50, Q60, Fuga, Q70, A62 Titan and probably heaps of others including Navara...)

      By Duncan · Posted

      I thought I'd do a write up on an auto transmission fluid change for a the nissan 7 speed Automatic. At some stage the genius engineers decided that the fluid in the trans was "for the life of the transmission", (which seems kind of self supporting to me) and removed the dip stick and fill tube (funnily enough there is still a casting for it). Anyway, for this job you do need 2 specialist tools in addition to regular hand tools, jack and good chassis stands. You need a way to pump fluid up to the transmission; I got one of these but there are plenty of other options: https://www.ebay.com.au/itm/364584087070 Don't trust the generic listing though, it does not come with the required adapter for the Nissan 7 Speed. You need one of these, can't do the job without it: https://navarapart.com.au/product/genuine-nissan-patrol-y62-d23-np300-navara-re7-dipstick-fill-connector1 You need a heap of compatible transmission oil. Could be Nissan, could be anything else rated for Nissan Matic S. You need at least 10 litres, I had 15 to give it a better flush... Also, you need some biiig oil catch trays, at least one of these, or bigger if possible (volume was fine, size was very marginal): https://autobarn.com.au/ab/Autobarn-Category/Tools-%26-Garage/Specialty-Tools/Oil-Service/Garage-Tough-Oil-Drain-Pan-Black-16L---GT1068/p/TO03191 Finally, a measuring jug is very useful if your pump does not have volumes marked on it, I got a 6l one: https://www.repco.com.au/oils-fluids/fluid-accessories/measuring-jugs/penrite-measuring-jug-6l-pmj006/p/A5322648 Oh, and gloves.....this stuff is horrible (not as bad as diff oil, but getting there) ....First, jack up your car.....

      So I mentioned the apprentice, @LachyK helped take the bonnet off. We just undid the nuts on the hinges and unclipped the gas struts, then pulled the bonnet back a little as the front was catching on the front bar.  I had a good look at everything today and have removed the rams, repaired/reset the hinges and bolted it back together like it never happened. I'll do a separate write up on the repair, and I also removed the poppers from the Fuga today too to save grief down the road.....as said above it is at least $5k to repair retail. I'm also happier about my ability to prepare a race car, and less happy about Nis-nault's engineering (I can hear @GTSBoy sAfrican Americaning) because the top hose of the radiator didn't slip off.......it snapped clean off. By practice I put the hose clamp hard up against the flare on a neck to make it least likely to ever move (thanks @Neil!). I guess that puts a little more pressure on the end of the pipe as it is further away from the rad, but still, that is pretty shit. I've put it back on for now as there was a fair bit of neck still there, but obviously there is no lip on the neck any more so I don't think I'll track it again until I have a new rad. Speaking of which....more research required. It looks like Koyo makes a standard size radiator in ally which I'll grab in the meantime, but I really want something thicker so might have to go custom in the medium term (ouch) Coolant still needs a refill and I have the pressure tester on it over night, but other than a wash down of the engine bay it seems alright. And @MBS206 noted something noisy on the front of the engine and I think I agree....time for a new accessory belt and tensioners I think.

      our good friends at nismo make a diff for it, I have one (and a spare housing to put the centre in) on the way. https://www.nismo.co.jp/products/web_catalogue/lsd/mechanical_lsd_v37.html AMS also make a helical one, but I prefer mechanical for track use in 2wd (I do run a quaife in the front, but not rear of the R32)
