HS30-H

This is the point at which a Facebook group would *call Carl Beck*, and roll out the digital red carpet... ;-)

Grande Nose is late 1971, so the 'G Nose' predates that crossmember/those mounts by quite a long way. I can state quite confidently that it's nothing specific to the ZG. The point about the horns is that these mounts simply move the horns forward of their normal positions. The horns then attach to the captive nuts in the forward end of the mounts, giving space for something quite big (like an aircon evaporator...) to mount in between them and the radiator. They are less horn mounts and more horn re-locators. Re-locating the horns is not their primary function. Oil cooler mounts is a red herring. The mount points for the (two types of) factory oil cooler are already in the (normal) body. Works rally cars never used anything like these mounts for sumpguards or spot/fog lamps. In any case, such mounts were 'free' in FIA Appendix J and didn't need to be homologated/attached to road cars to make them legal for rally use. If they are not the nascent air con evaporator mounts I am advised they are by people I trust to know, then I'll eat my hat and finish it off with my socks for dessert.

Well, I rounded up some opinions from *people who I thought should know* (no names, no pack drill...) last time I was in Japan. My use of "apparently" is a don't blame me if it's wrong get-out clause in case someone comes up with a plausible alternative story... ;-) Frame alignment is an interesting theory, but I don't buy it. If they are for frame alignment, what screws into the captive nuts? Some kind of measuring fixture? Where are the other reference points on the body then? Where's the factory literature to back it up (because shirley it would be for replacement panels in the field, and therefore the civilians need to know?)? Also, the lower radiator support crossmember is well forward of the alignment-critical areas of the unibody, and doesn't have anything of much importance hanging off it. Why have alignment-related hard points there, and for such a limited time? Doesn't seem to ring true to me. My main line of enquiry with them was aimed at nixing the idea that they were anything competition related. I don't think they are. In fact, let me be more definitive and say that I am SURE they are not competition-use related. It's surprisingly hard to prove a negative though. See? I knew we shouldn't have closed the case file on this one just yet...

Hi Kats, I think that bolt has had the oil pump duplex chain rubbing against it, possibly because the oil pump sprocket was not shimmed correctly on assembly. There are four grades of shim for the S20's oil pump drive sprocket and it is crucial to set it correctly. I don't think it is any kind of externally-caused accident damage. Much more likely to be an in-service failure and/or incorrect assembly. Not good!

When I mentioned the factory 'Roll Over/Safety Bar' mount prep points to ('Kaku U' team member) Osawa san in a conversation about competition influence, he had no idea they were even there. When I asked chief chassis engineer (also 'Kaku U' team member) Hitoshi Uemura about them he said "not my department...". It serves to remind that there was a cast of hundreds behind these cars.

I wouldn't close the file just yet. I still think there's more to be learned and understood about them and the story behind them. It's a mod/supersession that seems to have gone off half-cocked as far as I can see. I suppose we could surmise that the coming re-design of the rad support and lower crossmember (for the bigger radiator area) made the additional brackets obsolete, but I'm still curious.

Apparently they were part of a short-lived factory air con prep, relocating the horns to make more space for the condenser. 74820-E4201 was a factory replacement 'one size fits all' front crossmember/lower radiator support panel which incorporated them. It was superseded in 7/72. They are a little odd because they seem to be more often seen on cars that have had replacement crossmembers/lower rad supports fitted than on cars that left the factory with them...

You and our pal Grannyknot over here have something in common. Both fond of dropping lines which are easily shown to be a load of old cobblers. Apparently Sato 'couldn't drive' before he washed up in the IndyCar series, despite having been British F3 Champion, Macau GP winner and World F3 Masters winner before he even got to F1. Call yourself race fans? Even Lance Stroll 'can drive'. The vast, vast majority of drivers who pitch up in F1 and Indycar (even if it is riding on Daddy's money) can drive a car well enough to make the likes of you and me look like complete and utter tuggers.

Certainly don't want you to go to the trouble of coming up with any race results or statistics to back up your claims. Heaven forfend... But I'm still not clear as to which cars you are referring to? In reference to the lines I bolded above, you seem to be saying that S30-series Zs were raced in *stock specification* against modified Porsches? Where and when, please? I think it's nonsense. Porsche simply out-homologated the likes of Nissan during the period that the S30-series Z was current. They created cars like the aforementioned models (911S, 911T/R, 911R, 911S/T, 911RS 2.7 Carrera, 911 RSR 2.8, 911 RS 3.0, 911 RSR 3.0 Carrera) which could be purchased from a showroom and either driven on the road and/or on the race track, with factory support in readily available data and homologated, race legal competition parts. Nissan were not even trying to compete with that. It simply was not on their radar. They took inspiration from the 911R for the 432R (two cars of which you'll find no more enthusiastic fan than me) but the 432R was an exercise in domestic race homologation for JAF sanctioned events and it was never intended for export. Nissan didn't bother with FIA homologation for the 432 or 432R, their most sporting showroom-stock models of S30-series Z. I have been "following and examining the performance of various cars" from the late 1960s until now. In a previous post I mentioned that I was present at Le Mans as an 8-year old kid in June 1970 when Porsche took their first outright win at the event with the 917. I watched a Porsche 914/6 win the 2 litre GT class and a Porsche 911S win the 2.5 litre GT class in the same race. It made a big impression on me. I think I'm pretty well informed about the S30-series Z's race history (yes, including quite a lot of those pesky statistics) so I'm all ears if you can tell me something new. What have you got?

You are Lance Troll, perhaps? There's none so blind as those who will not see. Takuma Sato and Jenson Button took the Honda-engined BAR 006 to second position in the 2004 F1 Constructors Championship, with Sato scoring 34 WC points. There are many good drivers who have never scored a single point in Formula One. Sato's career before F1 tells us that he was a race winner and a championship winner. His F1 career came to an abrupt end because the cash-strapped Super Aguri team pulled out of the 2008 season after just four races, not "because of his erratic driving and for continually crashing into other drivers". I doubt that Sato - a self-effacing, decent, honest man - far from the Prima Donna type perhaps best illustrated by a certain Mr L. Hamilton, would claim to be the fastest and least mishap prone racer out there, but he has proved himself good enough, and in the right place enough, to win the Indy 500 whilst still being regarded as an underdog. And for that I take my hat off to him.

No, I think he just doesn't know anything much about motor sport.

If we're playing, here's a couple of shots to prove Takata - like most Japanese companies - were working on Christmas Day 1969. Nissan part number was 86800-E7201, and I think it should be fairly easy to guess on what variant of S30-series Z this was stock equipment:

Sato took the 2002 Jordan Honda to fifth at Suzuka in 2002 (in a season where the car broke more often than not), following it up with a sixth at his one-off run in the 2003 BAR Honda at Suzuka the following year. In 2004 he scored 34 world championship points in the BAR Honda when teamed up with Jenson Button. in 2001 Sato won the British Formula Three championship, the Macau Grand Prix and the prestigious annual World F3 Masters event at Zandvoort in Holland. I don't think he needed anybody to teach him how to drive before he took his career to the IndyCar series. Maybe you're confusing him with Alex Rossi?

Interesting, but a more than slightly non-sequitur post considering what went before it. What series, what races, what years even? I've been trying to elicit an answer regarding some cars that were - allegedly - "...just the best and far superior to anything else in the world concerning production sports cars at that time." So far no specifics... Meanwhile, as I have already pointed out, what manufacturer totally dominated the FIA International Cup for GT Cars during the period when the S30-series Z was being sold? Answer: Porsche. I have mucho respect for the likes of BRE and BSR, but they largely concentrated on national series races. However much we admire the engineering of their cars we can't compare them like-for-like with Porsche's best. Sure they punched above their weight some of the time, but they were not comparable to the might of a full fat factory effort that was sending cars all over the world to race and had a fleet of specialised homologation models to sell in their showrooms.

I'd say more like 1971, if not even early 1972. Most of those drivers were assembled for a similar shoot with the photos published in 'Auto Sport Young' (a special edition of Auto Sport magazine) in early March 1971, and the difference in hairstyle/length is noticeable. They were pretty much all following a trend for longer hair at the time and I reckon your photo was taken later than that shoot.

"...no Euro designed production car could match it." In what terms? You state "superior design", but what does that mean? What exactly was superior? I'm honestly wondering if you have come into close contact with any of Porsche's premium models of the period? I'm thinking 911S, 911T/R, 911R, 911S/T, 911RS 2.7 Carrera, 911 RSR 2.8 (how about the IROC RSRs?), 911 RS 3.0, 911 RSR 3.0 Carrera? That list takes us up to the end of 1974, when the S30-series Zs being sold in North America were still being offered with a choice of 4 speed manual or Automatic transmissions (FFS!). Porsche's stock-in-trade was making and selling sports cars, racing them and winning. They out-engineered, out-homologated and out-raced their opposition because they focused pretty much solely on doing so. You might well believe the S30-series Z is "a superior car to Porsche's offerings at the time", but I don't see any evidence whatsoever to support the belief. I guess a world that has space for Creationists has to have space for other kinds of fantasy too. By the way, I'm still nonplussed by the following statement: "...the US development of the racing Z covering S30 to Z31. .....those race cars were just the best and far superior to anything else in the world concerning production sports cars at that time." ...as you don't appear to have answered my repeated questions as to what specific cars it refers to. Considering you have now refined your claim to refer specifically to the S30-series Z I reckon it should now be easier to answer, no? So, a racing Z "production sports car" developed in the US that was "the best and far superior to anything else in the world" at the time. What specific car, please? You won't find many more loyal advocates for the S30-series Z than me, but I'm a realist who has been watching Porsches race from the late 1960s (yes, before the S30-series Z existed). To acknowledge Porsche's historic success in their chosen field - specialising in sports/GT cars - is not to diminish Nissan's excellent achievement in creating the S30-series Z. Two very different companies with quite different product ranges and philosophies. Being loyal to one should not make you blind to the merits of the other.

Correct the spelling for Yasunori TOSHIMORI and it will be correct, I believe.

"Yusuke Toshimori" = Yasunori TOSHIMORI "Tsujimoto Seiichiro" = Seiichiro TSUJIMOTO "Masahiro Hasegi" = Masahiro HASEMI "Yoshikazu Sunagi" = Yoshikazu SUNAKO "Kitano Yu" = Moto KITANO "Kenji Tsubairi" = Kenji TOHIRA Family names are in capitals, and in the Western format of given name first, family name second (whereas Japanese format is family name first, given name second). The "240Z' is actually a Works (Nissan Racing School) 432-R in drag.

The Kameari Engine Works HQ/store in Yashio City is an easy train (then taxi) ride from Tokyo, but it's a good idea to have the address (in Japanese) and a map printed out for the taxi driver at the local station, who may well be an 80+ year old who has never heard of the place... I'd advise you to give Kameari fair warning of your intention to pay them a visit, and also give them an idea of what you are planning to buy. They can send bulky items to your hotel by Takkyubin (you won't be wanting to struggle home on the train with big boxes under your arms), but don't leave it to the last couple of days of your trip in case there's any delay. Don't expect something the size of Walmart. K.E.W. are a compact operation. Small but perfectly formed.

Moving the goalposts on the pitch is one thing, but you appear to be moving them to another continent entirely. I asked you exactly what you were referring to when you stated "...the US development of the racing Z covering S30 to Z31. .....those race cars were just the best and far superior to anything else in the world concerning production sports cars at that time." and you don't seem to be able to specify which particular cars you are referring to. You now say that the World Sportscar Championship somehow doesn't count in all of this and "...anything else in the world..." doesn't actually mean what it says on the tin. So it's like the 'World Series' of Baseball's link to a newspaper rather than the 'World' implied by planet earth, right? Gotcha. There's no point in starting any kind of debate about S30-series Z cars circuit racing in Europe ("pathetic" or not) as Nissan simply were not ready - as a company - to embark on a serious Works campaign of that sort. They did however commit themselves to a rally campaign for the Z with the main focus on three 'halo' events - the RAC Rally of Great Britain, the Monte Carlo Rally and the East African Safari Rally - winning the Safari outright in 1971 and 1973 and placing a fine fifth on the Monte in 1971 (a result which astonished the rallying world) and followed that up with a third in the 1972 Monte. Nissan did take Works Zs to some selected events outside Japan to test the waters and gather data (including Brazil, Malaysia and South Africa) but circumstances - the 'Oil Shock' being the biggest - conspired against them expanding on that. From then on the focus would be mainly on four cylinder machines. My point still stands. If you want to talk about "World Excellence" in terms of sports cars and GT class racing during the period when the S30-series (and S130-series) was current, then Porsche were the reference point. No contest. There's no shame for us as Z fans to admit that, but it makes us look stupid to deny it.

OK, as I suspected, it's an example of custom/privateer fabrication making use of the factory-installed captives in the rear header rail. I guess it proves what they *could* be used for, and may well have been planned by the factory to be used for, but (as far as I'm aware) they didn't. As mentioned - I think - way back, there were at least two different positionings for the two vertical drops in the factory roll over bar/'safety bar'. There was the 'normal' gap width (as seen on the circuit race cars and the Sports/Race Option parts sold to the general public) and the factory Works rally cars, which had a wider gap between the vertical drops, to allow them to carry two spare wheels/tyres. I think the gap between the two sets of captives corresponds to one of the above, but I'd have to go to the garage to check....

That photo needs some explanation. It looks like a privateer/custom bracket fabrication to me? Despite the four captive nuts being in the rear header rail, I've never seen a factory or Works installation that actually used them. Certainly none of the Nissan Sports/Race Option four-point roll-over bars had them. I still think it's something that was mooted (hence those four captive nuts in that location) but never used for factory/Works parts.

Tee hee...

Like many road-going 432-R users, they probably found that it was a nuisance when night driving. In just the same way, quite a few road-driven 432-Rs ended up with gloveboxes, heat/demist controls and centre consoles etc within a few years of being sold.

96321-E4100 was the '69-up interior mirror for the S30-S Fairlady Z 'Std' model and the PS30-SB Fairlady Z432-R model, with no Day/Night adjustment. Many other Nissan models (especially in Japanese market) had similar style mirrors. What makes them Z specific is the curve of the stalk and the mounting.
