Datsun-240z Vs Fairlady-z432

Recommended Posts

Thank you nix240z, I am glad that some are already started to working on, and also most of others have potential to be made .

My friends in Japan are very interested in your products, but most of them usually hesitate to contact and have fear for paying online payment. Even they are  worried about shipping from the overseas.

I'll give an enthusiastic nod to reproduction of early items. As someone with 3 early-ish cars. I am always happy to see some of this stuff being made. Thanks Steve!

PS: I always recommend your site to people looking for pieces you sell.

I bought several AM radio faceplates from Steve, very happy with his products! Packaged very nicely and quality is great.

Hi Gavin, I too have bought many parts from Steve , before knowing he is a member here ! I am always so satisfied with his products.

I have a question to Steve . Can you make this and if you can make it , how many orders does it require and, how much it is going to be ?

This cover and tray is for Japanese S30, I would say probably 99% of cars are missing them. I would think owners would have been happy if they were available. A metal flame is replicated by a shop in Japan. Exports S30s do not have a problem because you are making assorted parts.

This is a quite bigger parts considering your products line up. But if you do not have problem making this big , I would ask such as  an early wiper motor plastic cover , a Z432 cabin air intake plastic duct , etc .

Thanks Steve, I have got the grommets in hand, quality is just fantastic.

I will make two early shift boots for these grommets!

Hi

Central 20's, one of the only proper period items I own.  I'm in love with them!

Hi Jason, this would be more suitable for your wheels, color of the magnesium wheel.

The one which has a part number sticker is an NOS, has never been exposed under the sun .

Beautiful wheels there.  Its a hard colour to replicate.

Sorry for the thread drift.  The middle colour of the 3 wheel pics is what i'm leaning towards, an anthracite colour.

I look it carefully, it is close to the color of the magnesium wheel. If it is flat , not glossy, will be much closer I think.

Drift is always welcomed !

How hard is it to get a set of those Central 20 wheels? They seem even more rare than the Kobe Seiko wheels?

I don't know.  It took me a year ish to convince the previous owner to sell me these :)

I think that they're rare, one other set in the UK that I know of, seem to be on a few 432's in Japan. I'm not sure of overall production numbers though.  Maybe Alan could pen his thoughts.

A set of Kobe Seiko would finish my shoe collection for the car.  however I need to get the car done to make use of any.

I like the shape of Central 20 wheels , sometimes it pops up on Yahoo auction Japan, yes I think it is rare to see. Most of them is gold spokes with a silver outer rim.

Today I show you a new old stock 5speed gear box “ FS5C71B” which is used for Z432 , Fairlady 240Z series and Skyline GTR . ( this one is specifically derived to Skyline GTR , as a part number 32010-R5530)

After Jan 1972, (for example  HS30-10635 And after )

FS5C71B was applied, but gear ratio was different from other model. Those three types of cars has very nice ratio.

1st  2.906  (3.321 std)

2nd 1.902 (2.077 std)

3rd 1.308  (same std)

4th 1.000  (same std)

5th 0.864  (same std)

Rev 3.382  (same std)

I have a question about export Zs which have 5 speed , are they have this special gear box ? 

I am thinking using this for my 240ZG , I will replace S20 front section to its original 

L24 one then I will sell the S20 front section (so many  S20 owners in Japan want to swap FS5C71A to FS5C71B, because it’s good feeling and plenty of parts availability) 

Also I need to have a spline type propeller shaft (my ZG has a flange type as an original  , soon after they went spline type ) this one will not be difficult to find because so many S30 models used this one since September 1971 (I mean longer one for the diff mount changed)

Or should I stick with its original gear box and propeller shaft ? Everything on this car is original down to exhaust tip with its build date stamp. Hmmm..

Alan , please let us know.

Hi Kats,

I will have to check my factory parts manual for HS30's (UA - Australian Market) to see if they list ratios along with part no.s but in the interim I have some press releases here.

https://goo.gl/photos/yGt15kkjKMxXx6Sb8

72 + 73 model years had the following ratios with 71B box.

https://photos.app.goo.gl/zB8zJzHE5MTlPffw2

70-71 model years had the following with 71A box.

https://photos.app.goo.gl/f6rwh6bxr9LKFumw1

 

Zoom in to see them. Or I listed below.

73 model - 71B box

1st = 2.906:1
2nd = 1.902:1
3rd = 1.308:1
4th = 1.000:1
5th = 0.864:1

Diff ratio = 3.9:1

Early 240z 71A box

1st = 2.957:1
2nd = 1.858:1
3rd = 1.311:1
4th = 1.000:1
5th = 0.852:1

Diff ratio = 3.9:1

74 260z 2 seater (71B)
1st  = 2.905
2nd  = 1.902
3rd  = 1.308
4th  = 1.000
5th  = 0.864

Discussion here:

http://www.viczcar.com/forum/topic/5575-260z-gearbox-ratios-what-are-they/

I have a 71b/C hybrid box in mine, with the closer ratio 260z 2 seater box gears for the first 4 gears and the taller 5th gear with reverse lockout to prevent shifting into reverse. We used the 71B/C hybrid box because my car is HS30 10552 - which had a 71A 5 speed from factory so the shifter hole is further back and instead of bending the gear stick back to fit, we used this combination so that the shifter would come out in the stock position.

Given your cars originality, I'd be inclined to stick with the original box.

I wanted to go back to a 71A box in my 72 240z HS30 10552 but I already have 3 other 240z's that will receive this style box. So decided against it for now.

Previously I had the 280zx/240K gearbox with the wider gap between 2nd and 3rd gears, synchro's were well worn, so it drives night and day different now. I also fitted Triple 44's at the same time, so it's hard to say which I like better. The new gearbox or the response of Triples. Both have transformed my L28.

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...

Thanks Alan ,  UK market is the same as the Australian market , I also checked the parts catalog for HLS30 except USA and Canada . The book says yes, the FS5C71B has the same part numbers for the gears starting from 2.906 .

In Japan, the gear ratio was discontinued after September 1973. Never applied to S30 models again.

I would say the ratio is not rare, it is rare only in Japan, after seeing Gavin and Alan posted above.

I am also huge fan of FS5C71A , first of all,

It has a look , things of beauty.  I can spend hours just looking at the gear box.

Japanese people tend to give up rebuilding the FS5C71A because they think no parts available , they do not know there are some nice parts vender in the US.

However, Mr.Kawashima who did wonderful work for my two FS5C71A now became famous among not only S30 community, also GTR and SP/SR . 

Mr. Kawashima recently started to service for R192 diff , he managed sourcing some NLA shims and bearings from manufacturers in Japan. He even also made special tools for disassemble and assemble.

I agree I love the look of the 71a box and I love the straight gearstick and how it sits in early S30Z's. Alan actually convinced me to go back to the 71A box in HS30 00150 and I just think it's nice to go back to the original feel and form of the car.

There is Lou Mondello here in Australia (Melbourne) who specialises in the Fairlady Roadsters and as you know they had the same 71A box but different bellhousing. He can apparently rebuild them also and has access to parts.

Gavin , you may also want your HS30 10552 to resume FS5C71A more , as you are getting to realize it is rare more. 

There are only 634 or less  “ HS30s with the FS5C71A “  with the NEW center console around the world ! 

And how many automatic transmission HS30s were there between HS30-10001 and 10634 ? As I see the Fairlady Z catalog , Nissan seemed to emphasize the automatic transmission. They wanted to make Zcar not only sports car but also easygoing car.
