hello! does anyone have the correct torque specs for the filler and drain plugs for:

  1. transmission: 
  2. front diff:
  3. rear diff:
  4. transfer case:

I have the service manual, but it only covers the engine, not the rest. I'm looking for specs on an r33 gtr, if it makes a difference.

thanks in advance, you absolute legends!

Well I happen to have those written down on a sticky note in front of me, but they are for R32 so use at your own risk.

1. Gearbox: Drain 18-25 / Filler 18-25

2. Front Diff.: Drain 18-25 / Filler 18-25

3. Rear Diff.: Drain 43-72 / Filler 43-72

4. Transfer Case: Drain 18-25 / Filler 7-14

All units are in lbs/ft., convert at your own risk.

Transmission:

Transfer case:

Front and Rear differential:

All taken from the R34 workshop manual, I'm pretty sure that the differentials and therefore the torque specs are the same. The R34 GTR transmission is different but they list a torque spec for the 30A transmission which is shared with the R33 GTR. Transfer case is a different part on the R34 GTR with a thinner chain. It would be nice to get the Japanese R33 workshop manual, the english manuals out there tend to not be as comprehensive and between DeepL/Google Translate you don't really need a fully translated manual these days.

Don't be afraid to use the lower end of that range for those tapered plugs. They have an amazing ability to self tighten over time and I have never seen one of them leak from being undertightened.

A guy I know near me recently rounded off his front diff plugs so definitely don't go nuts, especially with the fill plug. Spark plugs are about the only thing where I try to tighten to middle of torque spec instead of lower end of torque spec and I do it with the engine cold.

@joshuaho96 i found a manual that they sell out of NZ, that is supposed to have everything (engine, chassis, and some other stuff) and it sells for a decent price, but i don't know anyone that has purchased it. what i don't want to do is pay for the engine only file that everyone has been sharing.

@Duncan always chiming in with the excellent advice!

 

thanks all of you!

They mention that the engine manual is a crappy scan of their old translation uploaded to the internet. The 150 dollar manual is the complete workshop manual supposedly. I might spring for that down the road, it gets tiring to cross-reference against the R34 manual. The suspension components especially are different so I'm not sure what the torque specs would be there.

As far as I know, the only JPNZ R33 manual is about 500 pages and engine only. Given that JPNZ went to the effort of scanning, translating and collating all those pages, I'd encourage anyone who needs it to pay the small amount for the trouble it can save you.

I have not seen a scanned full copy of an original japanese R33 manual, although I do have the W34 Stagea one.

"Below is the index from the manual it is a copy and paste and not laid out as it should be but is the full index. Please note this is a full factory workshop manual not just the engine but a manual for the entire vehicle. Some idiot did copy our engine manual for this vehicle and sells it online and it is a shit scan and only covers the engine, since then we translated the rest of the Japanese manual which covers the entire vehicle. We get asked all the time if this is just the engine or the full manual. This is the full manual."

Good on them....massive job.....buy, buy, buy and give them a small payback for the huge effort they have put in.

I have the R33 chassis manual - it is excellent. Waited ages for them to finally do it, as I was annoying them all the time for full version in 2004 after buying their engine manual.

I find it much much faster to have the hard copy out. Speaking of, this is very very temping when back in stock:

It's the official Nisssn Australia 32 GTR manual. I know it's the one everyone has a scanned copy of including myself, but the fact it is still obtainable is tempting.

I reckon the scan of the 32 manual originates with me. I sneakily borrowed a copy from Nissan back in about 1999 or so. I made 3 photocopies (because scanning it at that point in time was actually a bit too much of a challenge) and distributed 2 copies to others who knew I had borrowed the original.

Although, the Nissan original was in a lever arch folder, not a bound book, so was probably a workshop copy anyway.

The PDFs that are around all contain some artefacts from my photocopies that were not on the original paper I copied. So I reckon one of the other copies got scanned early in the 2000s and ran away to the internet.

well, you have done the world a great service then!

I actually have the original hard copy too picked up a copy I saw a few years back like a seagull on a hot chip, I only really use it for tracing wiring as the scan it not really legible for a lot of the detail

    • Not sure the US can import anything other than the C34 Stagea's, but if you can and you need to to tow, DO NOT under any circumstances get an M35 Stagea. If it is just as a family car and your country/state allows it, absolutely and definitely get an M35 (3.5L if possible as it is effectively a 350Z) over a C34.
    • Punch your VIN (nm35-xxxxxx) into Amayama.com You can see everything there quite easily.
    • Thanks for that, I'll check it all out. I can always do the brakes last anyway if its a problem.  The 16's are super cool, if they do fit I'll cruise around with them for a bit.  
    • Well, that's kinda the point. The calipers might interfere with the inside of the barrels 16" rims are only about 14" inside the barrels, which is ~350mm, and 334mm rotors only leave about 8mm outboard for the caliper before you get to 350, And.... that;s not gunna be enough. If the rims have a larger ID than that, you might sneak it in. I'd be putting a measuring stick inside the wheel and eyeballing the extra required for the caliper outboard of the rotor before committing to bolting it all on.
    • OK, so again it has been a bit of a break but it was around researching what had been done since I didn't have access to Neil's records and not everything is obvious without pulling stuff apart. Happily the guy who assembled the engine had kept reasonable records, so we now know the final spec is: Bottom end: Standard block and crank Ross 86.5mm forgies, 9:1 compression Spool forged rods Standard main bolts Oil pump Spool billet gears in standard housing Aeroflow extended and baffled sump Head Freshly rebuilt standard head with new 80lb valve springs Mild porting/port match Head oil feed restrictor VCT disabled Tighe 805C reground cams (255 duration, 8.93 lift)  Adjustable cam gears on inlet/exhaust Standard head bolts, gasket not confirmed but assumed MLS External 555cc Nismo injectors Z32 AFM Bosch 023 Intank fuel pump Garret 2871 (factory housings and manifold) Hypertune FFP plenum with standard throttle   Time to book in a trip to Unigroup
