Newsflash for Grannyknot: The race in question was won by a 432-R pretending to be a 240Z so that it didn't get disqualified. You seem to have overlooked the fact that L24-engined cars weren't around to take part in the first ever race contested by an S30-series Z, or the first race won by an S30-series Z (READ THE NUMBERS). If you think you knew better you could pop back to 1969 and tell Nissan just how silly they were being putting Murayama's precious engine into their new American Sports Car as it would only lead to tears and confusion. And really, if the first post in this thread convinced you of anything it only goes to show that you didn't know enough to come to a view in the first place. The facts don't belong to me, and whatever I say about the 432/432-R won't change what they were, what they were homologated to achieve, what they did actually achieve in period and what they mean in context today. It's a key part of the S30-series Z story, despite the efforts of people like yourself who seem to want to diminish it for some unknown reason? What's that all about, really? Isn't it just the fact that you don't like the usual messenger? How about you pop up on one of Kats' threads and tell him his 432 is "not special"...? See how that pans out for you. My prediction is that you might find a few people to 'Like This' but not a lot else will happen. Don't worry though, you're not alone as you have a fantasy conspirator in my parallel universe Porsche thread. He's busy telling everyone that the Porsche 911R (Nissan's reference point for the 432-R) was also "not special", with similar reaction...

Clearly academic, but just in case anyone wants to know... That "400 RPM" cutout is a bit of a misnomer. They use the "N" output from the alternator to pull in the fuel cut relay #1, and that "N" output from the alternator is actually the "Neutral" connection of a three phase "Y" connected generator. The voltage on this neutral output is the normal alternator output voltage divided by the square root of three. So for example, when the alternator output is twelve Volts, the neutral wire should have about seven Volts on it: Datsun assumes that by the time the engine is spinning at 400 RPM or higher, the alternator is up and operating, and the voltage on the neutral output is high enough to pull in the fuel cut relay. So the "400 RPM" threshold is a little arbitrary, but the intent is "when the engine is running, the electric fuel pump will run". Geek mode off...

And no one ask himself .. must be a 300zx turbo? or '81-'83 year... I don't know if a old type 300zx has a R200.. all i know is that a 280zx was build till '84. please explain..

Here's the translation: I was able to see it as a race that achieved certain results by being able to confirm it. Based on this result, the development of Z432 is in a steady tempo Although it was thought to be advanced, Datsun Sports 240Z appeared in Fuji 1000 km just six months later. Not a 2 liter of 4 valve DOHC but 2.4 liter of 2 valve SOHC was chosen. Direct line of R380 For S20 type fans, it was an event that can not hide disappointment, but happened to be a series option, 2.4L engine It is a result unique to Fairlady Z which I had. "If the displacement is the same, it will obviously choose the S20 type, but the L24 type The difference in displacement of 400 cc that you have is great. Since the absolute value of the torque is large and there is torque from the medium speed range, L24 It was more suitable for racing, "said Masahiro Haseyami who returned to Nissan from this year. "With no other vehicles at all If I go around the course I think that there was not much difference between the S20 type and the L24 type at the time but always changing the line in the midst of battle Torque type L24 type engine became a big weapon in the actual battle to run. " L type engine There is another great merit in the 240 Z to use. Because the mechanism was simple, maintenance and tuning With regard to work on advanced technology like S20 type (although it is for racing reasonable level is necessary) It was an engine that can be operated on a tuner basis without needing it. After GT-R retires from active service The reason why 240 Z was supported by the private sector is that it is precious in this respect that supports the motor sports of the 70's It was a fighting power. Masahiro Haseyami, who has been involved in the development of the 240Z for the last time, left us an interesting comment at the end. "To tell the truth, Z was not very high in body rigidity, and in terms of body rigidity, the hard top body of GT-R It should be good to talk about Z, but the hard top body of GT-R was anticipating racing youth I am impressed again. The name of "Nissan of the race" is noticed that it is not Date as well. Speaking of this era, people of the former Prince family, especially since it will lead to R32 GT-R after ten years from here You can not but admire it. In the latter half of the 1970s which refrains from expressive activities, it can be interpreted that its existence was sparse, but it depends on private In terms of making the foundation so as not to stop the lamps of the motorsport activities, Nissan Works made the 240 Z The development and aging work had a very significant meaning.

Mike took a quick look but no pick.

I have a couple of LSD's but wouldn't part with either of them cheaply... Rusted? Inside or outside? Don't really care if the case has some rust. It's the guts that matter... Most LSD's you can source are an unknown quantity unless they were just pulled from a known vehicle. You will be hard pressed to tell if a CLSD is good or not from a visual inspection. I paid about $750 for each of mine 6 or 7 years ago and they haven't made any more since then... I am also not really offering them for sale here. The reality is someone will probably read this post that has one and might chime in if they feel like a deal could be made...

Looking just to optimize what I have without any heroics. Filtering air is important as it's mostly a street car I'd like to last a long time. I decided to try this route when I looked at the K&N filter at the end of the air box and it was all beat up from the engine shifting during revs and banging against the hood, etc. The dyno results were convincing, too, as I suspect the air box isn't flowing air like it should (I built it and it's basically just a box).

You'd better believe it. I don't want to read flippant comments dissing these cars or the people who were racing them. The title of this thread and the first post doesn't reflect the true scenario. Many of the guys taking part in this race were little more than enthusiastic amateurs in home-prepped cars. One of the 'six' mentioned in the thread title was a white 432 (not a 432-R) prepared, entered and driven by amateurs Isamu MIURA and Hajime SAKURAI. This is how their race ended on lap 35: Sakurai was 20 years old. The crash ended his race, but also put him in hospital with injuries severe enough to end his working career at that point. Sakurai had been a promising amateur racer marked out as a coming talent, but never raced again...

You are - quite simply - completely out of your depth. What - really - what value is there in your first post on this topic? That 'diamond rings and oil paintings' meme is all about the road cars. It still holds true (and don't forget it's usually an answer to somebody telling us that the 432 is "sh*t"). You get something put in front of you about one particular Japanese race (apparently it's news to you too...) and it's like you just realised that a G-Shock tells the time better than a Girard Perregaux. Hold the front page, huh? Perhaps there's a parallel-universe style scenario on a Porsche forum somewhere with somebody saying that the 2 litre Porsche 911R was "dumped" because the 2.7RS was "better". Hopefully the Porsche forum has one or two people who understand just how stupid that is... As for my comments regarding the real story behind that particular race (the context following tragedy...) you seem to have - once again - missed the point. Who said "the winner should not be taken into account"? Not me. Do you know what I'm referring to? My guess is that you have no clue. By the way, if anyone wants to see the original 'net based source of much of this thread, it's from this personal blog: http://vital.sakura.ne.jp/NISSAN SKYLINE KGC10 HP/index.html ...and this page in particular: http://vital.sakura.ne.jp/NISSAN SKYLINE KGC10 HP/S30kei.html ....which means it's already been filtered and weighted with some personal opinion. It is worth taking that into account.

And Blue, what's the true purpose of this thread? You've titled it "L24 Battles Six S20s. Guess who wins?", but why? You seem to be framing it as a simplistic L24 vs S20 fight, but it wasn't actually anything as simplistic as that. What's your real agenda here? The answer to the question posed by the thread title is, in fact, the latest Works car, with the 'ace' Works drivers behind the wheel... . You might like to remind yourself that the car in question was still in fact a 432R, running all the 432R-specific homologated parts and having the benefit of all the factory team development carried out up to that point. The L24 being installed in that chassis was far (far!) from stock, with special Works-developed crank, rods, pistons, head and many other details, and was running at a displacement of over 2500cc (yes, 25% greater than the S20) allowed by the GTS-II class rules. You can hardly frame it as L24 = great, S20 = $^!#, can you? Not only that, but I don't see any mention of one of the key points; The intra-company politics regarding the S20 engine and the fact that the very recently ex-Prince faction at Murayama regarded the S20 as 'their' engine and had effectively blocked the Nissan Works faction at Oppama from the better developments, updates and trick parts that the Murayama based team were using on their Skyline GT-R race cars. Murayama were not involved in racing the L6, so there was no potential for a reciprocal arrangement. Discussing the race career of the 432R without taking into account any of the Murayama/Oppama politics is to miss much of the point. And with regards specifically to the 1970 Fuji 1000kn race, you missed the elephant in the room for the whole event. Is that because you chose not to mention it, or because you didn't know about it? The big clue is what that particular event was supposed to be, and what cars were supposed to be taking part in it but for a recent tragedy. It had a huge impact on the race, and who/what won it.... It really ought to be taken into account.

I'm amazed nobody has listed this link. http://www.zhome.com/History/ZColorGallary/ 903 is the one of the original colors offered in 1970. It is solid blue. 115 is metallic. Introduced in 1972 or 1973, it sparkles. The 903 example photo is actually a vintage Z, repainted in PPG paint with their color matching. This is Kats' car - 903 blue
