Thank you Blue , that is a good picture. I have just taken this pictures under the sun, I see a teeth coming from the side which does not have a round window. According to a mechanic who has rebuilt a R192 four pinion LSD, 6 plates inside (4 plates of two pinion) makes the case thinner to have enlarged plates space. Do you agree this LSD is four pinion R192 ? Kats

And this is my spare used R192 LSD two pinion type. Kats

Hi Alan, your S20-000877 is also a good example, casting code is corresponding to the serial number. My 000884 is a bit later from yours , so that my casting code is showing bigger numbers than yours. Alan and anyone please help me to identify this LSD, do you think this is a correct R192 "4 pinion " / 2 way LSD ? I only see two round windows which are open for pinion shaft, these are supposed to be four , are not they? And two way or 1.5 way, it looks two way for me, but I am not for sure. I visited Matsui -san today, he said hello to you Alan, I wish I had plenty time to talk with Matsui-san , it was so fun. Kats

Blue, I will make thousands of copies for my project .Nice idea ! Kats

Engine casting code, this thread is useful. Kats

A front cover of the S20, an unusual surface at top of the crank hole immediately caught my eyes, what is that? I am worrying about this cover has had repaired once before, has not it? As a reference, the third picture is my Z432's cover, I see a lot of casting small dents, and some rough surface at top of the crank hole. I need to look at it more carefully. Kats I see casting code, "9 6 6 20 " I think this means "1969 June 6th " , I do not know last "20" And the water pump, temporarily a GTR one is fitted.

Hi Alan, thank you for your input, that is what I was expecting. Mr . Yamamoto said the engine pulled from a Z432-R, but everything which I saw was a standard S20 engine parts . I understood that is correct, Z432-R which was sold to the public has a standard S20 engine. When you want to race , you have to buy and install race option parts into your S20 engine, I got it. I have seen and missed race option piston, 8H/8L camshaft, camshaft sprocket , but if I managed obtaining those parts, it would not work. I need to have a specific head gasket, specific valve springs, seals, etc, etc.. And professional assemble work. It is just a long way !! Kats I restored my race and rally manual , Terashima-san kindly gave me . I used the parts catalog' s picture. The Z432-R is exactly the same size picture of the manual.

Hi moelk, yes it is. I am so impressed that they are so beautiful, so clean , and installed some race options. Kats

Hi Gave, I am wondering about future price of our car and other old cars. When can I trade my Z432 with a Dino 246GT (or 206GT is more suitable for 2000cc car)? Never going to be happened? If I have a Z432-R , I would be able to trade. On the side note of this Z432-R , recently this car was bought by Japanese car guy in Shizuoka , Japan. I think I said there is a gentleman who has three Z432-Rs in Japan, his cars are pristine and still upgrading the level of originality. We will see them someday in the future. Kats

That is right, this car has trimmings! Additional items which are not harming original parts are better than "missing " Kats

Thanks everyone, By the way, some Z432-R will be showing up on the market not so far from now. Every owner becomes old, wife wants to sell the car. This Z-432-R was sold recently at 55000000JPY( approx.500 000 USD), we do not need to hurry for availability but, the price is going up like this. I guess millionaires are mostly out of Japan, so these cars will left Japan , sadly. Kats

Thank you everyone, we have more to discover, let's keep going. Today I went to a shop , to see a S20 which is going to be my Z432's spare. Mr. Yamamoto is very passionate about S20, LY engine, he loves racing. Mr. Yamamoto said this engine might come from a Z432-R which was totaled , I will be happy if it is true. Does Z432-R's engine have racing piston, racing camshafts from the beginning? Alan , let us know. Kats

Thank you Manny, I received mine today, I am so happy with the perfect tags ! Kats

I think so too!! Kats

Blue, thank you for the useful information. I checked my blue 240Z's SU, they have same oil (0W-20) , same amount, but not same force (very stiff though) to lift up the piston. Also not same timing when they drops. When oil is empty for both, the force and timing is the same. It will take much more effort to find out what is wrong.. I have bought nozzles from MSA, they supposed to be black plastic do not they? Also repair kit, the tube does not have to be cloth braided, this tube makes me wonder if it is going to be a problem due to not so flexible. Small things make me wonder. I hope these parts will work perfect. Kats

Thanks Alan ! Now I see the reason. I do not want someone like this to overhaul my engine!! I am asking Matsui-san to hear some advice for installing the gear driven pump. Kats

Gave, I do not know that, I will ask Ando-san about it. R-Factory is the famous shop , the owner Aihara-san rebuilt the engine. Aihara-san has rebuilt so many S20 for customers. This yellow Z432 has an unique all gear driven mechanism (including cam shafts gear driven) which is produced by Aihara-san. You can hear different sound from other S20s. Kats By the way, do you know who is an owner of this car? Mr . Nakamura Shiro , a former senior vice-president of Nissan. He got this car a few years ago. He was a chief of styling department. I hope Nakamura-san tells designers "make S30 again! " .

Here is an oil pump for S20, this is a gear driven type only used for the early GTR. When Z432 was began to produced the pump was already switched to the chain driven type. I took pictures with a chain driven pump for comparison. An engineer said in an interview in a magazine, the change was made for reducing noise level. But later, many owners want the noise, we feel it as racing sound, we think it is music rather than noise. Some car have altered with this gear driven oil pump, I want to here the noise in some day. I found one terrible thing on the spare chain driven pump, a bolt head is scratched half ! What happened with this engine?? The car had an accident in the front section ? Kats

Thanks everyone, I really like these conversations, anything is well come here. Gave, I too think the support member is generic , as Alan mentioned it has a part number Z432 code, E42 . That is strange because Z432 does not have air conditioning system. And we see the member even has a small brackets for a Z432's air filter box. Would Nissan engineers have intended to put the two big rudders just for horns for Z432 with an oil cooler , and for a condenser for air conditioned car ? "If you do not use it, just leave it" Kats

Here is my 12/1971 automatic 240Z, it runs very nice.I do not know what oil is in it. Kats

Hi Mark Maras, ATF ! I have never imagined it , thanks for the information. Kats

Thanks everyone, bartsscooterservice, I am looking at ZT website, seems to me the roller bearings are good for the butterfly moving, they will give much smoother and almost trouble free for years to come. I saw ZT's 920 gold 240Z at Las Vegas convention 2000, I took my Blue 240Z there too. I am afraid my SU's shafts are sucking air due to wear. And how is everyone doing with the SU damper oil? 0-20W is stiff for the pistons movement, I will try much thinner oil. Kats

Thank you too 240Ziggy, we love tags, and stickers ! Just for someone's interests, here is the tag's location and facing. Nissan made a single facing application for each belt, as the results, tags are not facing the same at the driver's side and the passenger's side when we looking at in position. One important thing is, the tags must not be flat with the belts, tags must be loose so that tags can be twisted and bended without breaking / peeling . These tags are my home made tags on Z432. Kats

Thanks Blue and Alan, We want to know what purpose does these nuts have for ? Kats

Hi , thank you for the information, the shafts are notorious when they are getting old, I want to check my SUs after seeing your reply. And also some car magazines reported on "new car test" , the throttle pedal was sticky. My blue 240Z had same sticky throttle problem when it was restored like new . Maybe ball joint linkage? Kats
