HS30-H

Great Magnesium scare stories guys. Meanwhile, Nissan's Kobe Seiko 'Rally Mag' and '432 mag' wheels were made from Elektron. If you find yourself in a situation where your wheels are on fire, you're probably half past cooked in any case. If the 60-odd litres of fuel in the tank, whatever oil is left in your engine and the fumes from the plastics of the interior haven't already killed you, you can at least luxuriate in the white hot expense of burning magnesium alloys turning your bones to dust...

Case in point: My 432 type airbox was supplied as a replacement part via Nissan, in the Tsuchiya house blue. If it had been fitted on a 432 ex-factory, it would have been a particular shade of red.

That blue was manufacturer Tsuchiya's 'house' colour for Nissan product. When parts were supplied as OEM replacement - as opposed to when attached to a new car - they were supplied in Tsuchiya house blue. Happened on other models than S30-series Z cars too. Some Nissans had the Tsuchiya blue as stock equipment, so less impact in those cases.

Stock water pump delete! Love the 'Orange Box', and the Magnesium valve cover must be a Works item. Fantastic!

Nissan Sports/Race Option exhaust manifold! Just like mine. Hand made! Lovely...

Works rally car identities, race entries, crews, start numbers and all the rest of it are a real minefield. Lots of the photos you can find on the 'net are mis-captioned or don't tell the whole story, and even some of the protagonists themselves don't remember as well as would be ideal... Case in point is with Shekhar Mehta on the 1971 and 1972 RAC rallies. Both times he was in a car with start number 26, but they were different cars that often get mixed up. The car he drove on the '71 RAC had also been a 1970 RAC Rally car, so plenty of scope for confusion. Big topic.

Gav, The caption doesn't fit with the event there. The photo is '4541' (originally part of a batch of Works cars built for the 1972 East African Safari Rally, which started in March) on the 1972 Acropolis Rally in Greece (it took place in May). It was an entry in a "borrowed" Works car co-ordinated by Cal Withers, and Shekhar Mehta had negotiated a tyre sponsorship deal with Sears Roebuck. Apparently the tyres were not the best tools for the job (to say the least...) but the money was right. The white roof was an attempt to reflect some of the strong Greek sunlight and keep things a little cooler inside. I doubt it had all that much effect. The data from the Tour Of Dean website for this car relates to when those Tour Of Dean rally stages were used as part of the 1972 RAC Rally (December), where the car had start number 26. It still had the white roof and some of the white banded Sears tyres...

Sorry I could not see you, Kats. Maybe in London next time?

The stock centre mount (numbered 7 in my post above) attaches to captive nuts in the diff crossmember. One on OEM single pipe systems, two on OEM twin pipe systems. I don't know where you read that the new system was "developed for the 280Z"? That might be something a bit lost in translation? Fujitsubo themselves have not mentioned anything about the 280Z in particular as far as I'm aware. I think the new system is designed to work on a wide range of production years, and - as I understand it - they have not welded mount tabs to the system itself because they wanted to allow more scope for custom mounting methods through the use of band clamps which can be positioned on a case-by-case, car-by-car basis.

Which bit in particular? I don't want to scan each individual photo...

Kats, I have had SO many people over the years tell me that my ZG was "damaged" or "wrong" because of this detail. They haven't seen genuine OEM parts before. I was always reassured to see 'the gap'. It was a semi-secret way of telling OEM parts from replicas. Thank you!

Lovely 'ZStd' details. I noted the non-heated rear window and switch blanking plug, rubber mats instead of carpet, no bumper trim and can just about see the clock delete blanking trim (I want!). Rear spoiler would have been a later addition. What a great survivor. Chassis number is probably close to that of my '70 Z-L. Love it!

Hi Kats, Yes, after January 1972 (according to UK market factory documentation) UK market HS30s (and RS30s and GRS30s) received the FS5C71B transmission with the following ratios: 2.906 1.902 1.308 1.000 0.864 REV: 3.820 So, they were the same as yours quoted above, but they had the sliding spline type rear joint instead of the flange type seen on the Japanese market models. Personally speaking, I love the FS5C71A when it is in good condition and well set up. However, the design seems to have a very short ideal operating window and wears relatively quickly, and then it's horrible! The FS5C71B seems to stay nice longer. I think a lot of people only have experience of these transmissions when they are in bad shape, and that's why so many people (especially over here) are changing to later C type transmissions...

I don't know about your version, but my (old) version of the Spirit Garage system was designed to use the stock horizontal Nissan hangers forward of the diff.

No. They originally came with white paint where the red paint is now. Somebody painted them red, that's all. The only factory 'Red Z' for Japanese market S30-series Z models was on the horn pad of the S20-engined 432 and 432-R models.

Your comment being an example of the latter...

So when Nissan did it on their S20-engined cars and on their works race (S20 and L6 powered) and rally cars (L6 powered) and the likes of BRE and Bob Sharp followed suit on their race cars, you believe it had no reason other than "sound"?

Hi Kent, If you look for Peugeot 505 GTI vented discs you should get the right ones. They are best used with the late '73-up ('260Z') hubs, as that way you don't need to use a spacer. The '260Z' type hubs are distinct from the '240Z' type as they don't have the scalloped cut-outs in the wheel mounting area and are a solid circle of metal when looked at straight-on. However, there's now a new alternative. Kameari Engine Works in Japan have commissioned a reproduction of the original Nissan Sports Option vented type disc (long unavailable from Nissan/NISMO), which is a straight bolt-on to the '240Z' type hubs and has the right offset for the vented MK63 calipers. Back to a proper off-the-shelf bolt-on kit again.

Fujitsubo quote the current pipe diameter - several times in several different places - as 50.8mm x 2. Volume 13 of NOSTALGIC SPEED magazine - published July 2017 - carried an 'Advertorial' feature on the new Fujitsubo Legalis R system for the S30-series Z. See scans below: Old design on the right, new design on the left: Box on the bottom right gives data for an L28 engine in the tested car. Apparently their improvements have been realised through various changes, notably the exhaust manifold and the resonator box re-design.

Sean, where's the data regarding pipe size? A little bit further back up-thread you were quoting *STOCK* Nissan twin pipe system pipe diameter, but I am 100% sure the Fujitsubo systems use a bigger pipe diameter than that. Where are you getting your data from? Another thing: There seems to be a discrepancy between what the re-sellers (RHD Japan & Whitehead Performance?) are claiming about applicable models. I notice that Fujitsubo themselves are quoting fitment on chassis made between 1969 (Showa 44) and September 1975 (Showa 50-9). Caveat emptor. Also, "stock L20"? Where's that come from? In my opinion you're in danger of throwing a bit too much shade in Fujitsubo's direction. As a manufacturer/supplier of competing product, you have a dog in this fight. If I were you I'd concentrate on your own product and let the market decide.

From back towards the beginning of this thread: As with many things on this forum, we've been there before. Mike has a colour version of that Transcendental Racing/Frisselle/Morton shot.
