HS30-H

Just in case you haven't seen it, here's a factory document showing the system as fitted to Japanese (RHD) variants. You can see the hose and grommet that go in your drain hole:

I would imagine it was a matter of cost, weight and complexity (both in hardware and in fit/no fit building and ordering). The struggle in keeping weight down for some markets was something chief engineer Hitoshi Uemura often mentioned in his stories about the creation of the S30-series Z, so it may well have been a key factor. Nevertheless, the aircon-related details were built into every bodyshell, as well as the basic design of both RHD and LHD heater/fan units.

"Thanks Mr K!" /jk

It's the drain hole for the factory air conditioner that was never offered on the Export market cars, only on Japanese domestic variants.

@Derek Maybe this would be a good time for you to mention that there are already two of your Datsunworks KN20 head conversions (soon to be three) built up and running in Japan with this very same GIKEN CC and NISMO 32010-RRS50 reinforced 6-speed transmission conversions attached to them. Like I said, I think Sagami san of GIKEN CC knows what he's doing and it would be a shame if his engineering facilities, capabilities and judgement were to be called into doubt by omission. The NISMO 32010-RRS50 is an off-the-shelf product that's been available for quite a while so there's plenty of hard data and personal user reviews out there (largely in the S13/S14/S15 scene). NISMO Japan has some nice hard data and graphics here: https://www.nismo.co.jp/products/web_catalogue/clutch_mission/reinforced_cross_6-speed_transmission.html Torque 'capacity' is often quoted at 40 kgfm (392 Nm) but I would have thought such values are more than a little subjective. @Zed Head Call me old fashioned if you like, but I'd recommend that anybody with any serious questions (rather than just arcane, onanistic point-scoring nitpicks ) might be well advised to contact the supplier of said parts and ask them there.

Give it a rest, FFS.

Derek, are you aware of GIKEN CC's other work? I think Sagami san knows what he's doing...

Godzilla Raceworks are offering CD009 and Aisin TL70 conversion kits, I believe? Not the same as the NISMO reinforced 32010-RRS50 6-speed. As for GPS signal to cable-driven speedo, Speedhut SPEEDBOX is a good option: https://speedhut.com/speedbox

Clearly stated on the S30.world web page for the transmission, the Japanese designer and manufacturer of the front case and bellhousing conversion is a company called GIKEN Combination Company ('GIKEN CC'). I also mentioned it in my above answer to your question: I rather doubt that - admirable though Derek's work is - either GIKEN CC or S30.world will have got the idea for an L-series conversion kit for the NISMO S15 6-speed from Datsunworks. Nor will other manufacturers of similar products such as ESCORT Japan, who have had their version on the market for at least two and half years already. Conversion cases/bellhousings are hardly a new idea. are they? I believe the owner of GIKEN CC - as a fellow automotive engineer and machinist - is an admirer of Derek's Datsunworks KN20 cylinder head and that's why he is prepared to make a custom front case/bellhousing for a customer to mate the Datsunworks KN20 with the NISMO S15 6-speed in the same (clocked) way that the NISMO twin cam head conversion can be. As for your thinking out loud/stream-of-consciousness style musing on the word 'Takumi', I'm somewhat nonplussed at your direction of travel. Clearly (maybe not...?) the word 'Takumi' is simply being used as a catchy name for a particular themed line within S30.world's product range. No idea why you'd want to dissect it any more than that. Maybe - to stop the universe getting lopsided - there's somebody in Japan wondering why the word 'Craftsman' is written on a wrench...?

I think you've got your wires somewhat crossed again. The S30.world 'Takumi Series' TS-001 version of the NISMO 32010-RRS50 transmission uses a front case and bellhousing to match the L-series engine which is manufactured in Japan by GIKEN Combination Company (GIKEN CC).

It opens OK for me. Maybe your recent browser problems are to blame?

Hi Keith, Remember that this is about Japanese domestic variants (Fairlady Z, Fairlady Z-L, Fairlady Z432 and Fairlady Z432-R) with vented tailgates and non-vented quarters, not "non-US" variants. No rear-facing indentation (because it was not a vent...) and they fit flush to the body all round. They are assymetric (to fit the body) and oriented L and R with the letter cast-in, and - like the bonnet/hood 'Z' emblem - have an arrow pointing UP. An upside-down 'Z' just won't do...!

The early production changes to the '240Z' emblems are a legacy of the late decision to change the naming of the Export variants. Japanese market 'Fairlady' variants received a round 'Z' script emblem on their quarter panels which didn't change until the universal vented 'Z' quarter emblem was introduced. That design pre-dated the '240Z' emblem... In retrospect it's hard to understand why the Japanese market round 'Z' emblem could not have been used on all variants - Domestic and Export - until the vented emblem switchover. The '240Z' emblem, to my eye, always looks a little incongruous in that location. Too many angles and sharp edges in conflict with the swooping and flowing lines of the body. Round 'Z' script much more harmonious.

You have form. Just last week you were accusing me of "acting on behalf of the vendor" on an Australian market HS30 that you were making negative and ill-informed comments about on your BAT thread, when this was a scenario existing only in your own head. You accused the car of having the wrong engine, wrong transmission and then the wrong cylinder head. All false allegations which may well have negatively influenced the auction result, but little to no contrition from you. And then you wonder why BAT moderates your comments? Your accusations of me of being involved are the same conspiracy theory type nonsense which reflects your now-deleted "scam" comments about S30.world (before the penny dropped for you) and your rapid back-pedalling when you finally understood what they were about. Embarrassing to read on classiczcars. For shame! I see through you, even if nobody else does.

@Zed Head - and anyone else come to that - read back your first post and reflect on your position here: How's that intended to read? You seem to imply - as is so often the case - that this story is some kind of fabrication or exaggeration. Fits your usual MO. In the context of your (disgusting) denigration of S30.world on this forum - within the last six months no less - and your barking mad conspiracy theory nonsense about payola (accusing me of having a financial interest in S30.world, which you repeated last week) why should I give you the benefit of the doubt? You made your bed, now lie in it. You're whining about the second post in this thread when the fact is I've responded with an even-handed and fair post. I gave you the benefit of the doubt. Yes, many people may not be aware of Nissan's Sports Option parts, but how does that warrant your negatively slanted commentary on them? If you'd been paying attention, we have discussed just these very parts on classiczcars in the past, with photos and part numbers to boot. What's your projection of cynicism about? Doesn't make any sense to me. It is - all things considered - very strange indeed. I view it in the context of your past comments about S30.world on this forum, so how about you take some time to reflect on their consequences? You do a great job - with thousands of posts - helping people on this forum with your expertise, data and advice on subjects for which you have experience. But when it comes to certain subjects - and certain people/organisations - you seem to reveal a chink in your armour which is not pretty to look through. Look in the mirror.

Keyboard playing up? Probably getting a bit cheesy under those keys now that you're knocking 20k posts. Make sure you shut it down before giving it the wet sponge treatment. And don't put it away wet.

I have period Nissan Sports Option adjustable platform struts on three of my cars. I know a fair few other people who have them too. Seeing as these parts are news to you, maybe it's the case that you 'saw' them but didn't know what they were, so it didn't register?

It's not written very well on the auction description, but the car in question would indeed have been fitted with an E31 cylinder head when it left the factory. I guess the "high compression" distinction is being made to confirm that it doesn't have a later, lower compression, E88 head casting. Many E31 heads were replaced over the years with the more numerous E88 castings due to cracks forming between their valve seats and corrosion around the coolant passages causing head gasket sealing problems.

You're still at it, I see. I'm reading the auction description and it says - clearly (although not clearly enough for you) - "refurbished in the early 2000s". I don't know what you are expecting but I look at this car and see a fairly honest rolling refurb with some non-originality (it's not a sin) which would be similar to many of the cars owned by members of the classiczcars forum community. I don't see any claim of concours-level originality or bare metal nut and bolt type restoration and the photos speak for themselves in showing a well used 56 year old classic car. Why are you giving this particular car so much of your unfocused and ill-informed attention? Yes the auction description and photos are perhaps less than perfect (if the dash is pretty good then take the cover off it and show it) but that's being matched - if not exceeded - by your asinine comments on it. Your "Any ideas on where the original engine is?" comment is still up there, isn't it? Brake line material "wrong" in what sense? Again, I don't see any claim of it being "right". Looks to me like a typical Kunifer/Cupro-Nickel aftermarket set sold by the likes of Automec. As far as I'm aware there are no steel aftermarket brake hard line kits available for RHD cars. How is an E31 cylinder head "wrong" for this car? A 1970-built Australian market HS30 would have an L24 fitted with an E31 head as stock equipment. What else would you expect it to have? Yes, it doesn't have it's stock wheels any more. Four of the five other 240Zs currently up for auction on BAT don't have their original steel wheels either. Here's your chance to drop a comment on each of those auctions too. However you might have trouble getting past the BAT moderators now that you've embarrassed yourself by suggesting a car doesn't have its original engine or transmission when it clearly - yes, clearly - does. From the auction description: "A stainless steel exhaust system is fitted...". You're looking for factory stock features on an aftermarket exhaust system, then? Really? To quote the great Leroy Pullins (one for the Saturday Night listening thread)... "Is it wetter underwater if you're there when it rains? Is it shorter to New York than it is by a plane? Between myself and I, I wonder who's the dumber Is it hotter down south than it is in the summer?" https://genius.com/Leroy-pullins-im-a-nut-lyrics

You haven't got one, have you?

If you can't tell the difference between an A-series 5-speed and a B-series 5-speed I recommend you subject yourself to a crash course in early Z transmission identification. The car in question was fitted with an FS5C71-A as standard equipment. The photos show it clearly. Even the sliding spline centre joint propeller shaft photo confirms it. This stuff is early Z 101. You really are a piece of work aren't you? I haven't forgotten the sly comments you made with regard to my "shares" or financial interest in S30.world (more stuff that exists only in your head) so I already know what to expect from you. Put a sock in it before you embarrass yourself further.

Trust me. It's the original type FS5C71-A, as I pointed out above. Not fitted as standard equipment on North American market variants, so I guess you might not be familiar with it.
