According to this page.
http://jdm-car-parts...atsun-240z-260z

Back in early 70s', Nissan offered this type spoiler only to NISMO authorized racing teams and shops in Japan.


I've got great respect for Jay Ataka of JDM Car Parts, but sometimes his knowledge of the Sports Options and race parts is not really up to snuff.

Two problems with his statement: 'NISMO' didn't exist by that name until 1982, when Nissan's in-house race divisions and the standalone Nissan Omori "factory" were realigned to form a 'new' division. Previously Nissan's in-house race departments had been known as 'Nissan Sports' and various other monikers, and the selling of the race option and sports option parts was spread around a bit too much. With the formation of NISMO the idea was to rationalise and centralise as much of this as possible. Nitpicking I know, but why refer to 'NISMO' in a time period when 'NISMO' was a Telex address?

Second problem is that no such spoiler can be seen in any of Nissan's 'Sports Option' or race option lists and catalogues for the S30-series Z. So if Nissan were selling it, how were they marketing it? Was it some kind of secret? No, the answer is that it's in fact an aftermarket part based on something originally made by a company other than Nissan themselves.

It's very similar to an item sold in the early 1970s by Scuderia Nissan (despite their name, nothing to do with Nissan) who were racing a few S30-series Zs and had a thriving FRP parts business. My guess is that Scuderia Nissan may have been the original authors of the design, but it's been copied and copied and copied for the best part of 45 years since then...

I hadn't realised it was 6 months since the last update. I was going to wait, but there is some news to share. When I was in Melbourne I dropped my E31 head down to Les Collins workshop (Stewart Wilkins is very busy - hence going interstate). The cylinder head has some corrosion in the combustion chamber from sitting 20 years. So the cost to refurbish the head is a little bit higher than expected the chambers will require some re-welding and repair, but... since it was the E31 I decided to go ahead rather than use an N42 or later cylinder head. On an early girl it just feels a bit more 'correct'. I am fully aware for the most part it's just a casting number.

 

Camshaft specification is likely to be standard A-grind or a mild cam to suit induction (SUs). This way I'll retain standard rockers, lash pads etc..Cam towers will be changed from external oil bar lubrication to internally lubed camshaft and towers to suit.

 

I still haven't fully decided on the block, but I think I'm going to use an L24 block also (even if it won't strictly be matching numbers). I have a spare L24 crank from my 72 240z and 2 L28 cranks (2.6ltr) laying around. Not sure if I'll give her the slight bump yet.

 

I am doing this to stick to a sensible budget, rather than modify while it's apart. For those wondering yes, there is good reason for sticking to a budget which will eventually come to light, but for now it's an Auszcar secret. ;)

 

Benefits of staying stock are, cheaper to rebuild, I can retain the SUs rather than "need" triples along with the standard airbox and I think it will set a good baseline if I do hot her up in future. Also a standard motor will be easier to drive, so my partner can also drive it relatively easily. I forgot that driving an S30z is not quite as easy as modern cars and I think this will be a good way of getting her comfortable driving an older car.

 

Finally I opted to go for water jet blasting on the cylinder head and valve cover after seeing a couple of P90s with the treatment down at the shop I thought the finish was awesome and not too much "hot line bling".

In other news, the tafe course should resume a couple of weeks into February so I should be able to get cracking on the body again. This years build moto is to outsource a few more jobs and get the project moving along faster.

Good to see progress Gav, the cover looks like it just came off the production line, well done ;-)

I like it because it gives it a very plain like new finish. I remember when Adam's Brown Hornet was done and I saw how he opted for the flat alloy look I really liked it. I think James at MIA Engines in DeeWhy had used a scotch bright pad to get that finish on it.

 

The water blasting is a little more bright than the dull look of Adam's valve cover.

 

 

Ultimately I think you can have too much bling. This is a bit more understated. The finish looks even better in person! I am anxious to see the cylinder head with it also.

Good to hear things are moving along Gav, it's easy to lose enthusiasm on the big projects.
Do you have a dead line in mind, or more along the lines of "when it's done, it's done"
The water jet blasting finish looks great, does the cover in that photo have a sealer on it? Do you think carbs (Webers) could be treated with it? How much does it cost? And finally, any idea on where this service is available in Sydney?

Did you consider using your LD28 crank to stroke out to 2.7L as a possible build scenario?

Yeah tell me about it, that's why I am willing to outsource more work. I have plenty of work cut out for me without trying to do it all.

 

Deadline, well I originally bought it off eBay thinking I could get it running and slap it together as a rat rod, that was before discovering the seized up motor and the rust spots. Last year I couldn't attend the Tafe classes from mid-end year for a combination of reasons. So that set me 6 months behind. I just hope by the end of the year I have a lot more to show than the end of last. Let's put it that way.

 

I don't believe it has any sealer on the cover, my understanding of the water jet blasting is that any oil leaks can easily be wiped up unlike the standard finish where it can impregnate itself into the surface. It sounded good to me, hence the reason I went with it. We will see if it works in practice though.

 

I am pretty sure Peter Mac posted a photo of some Mikuni's that had been blasted, don't see what harm it would do. Gotta be better than other solutions! Between the head and the cover it was about $200 (so $100 each). I don't know anyone in Sydney I'm afraid.

 

 

Did you consider using your LD28 crank to stroke out to 2.7L as a possible build scenario?

 

Not sure if you will take this the wrong way, but this is exactly the kind of thinking I am trying to avoid. I am even keeping the stock valve sizes in the E31 head. Why? Because every modification has a knock on effect. If I increase the valves I have to do port work, if I do port work I may as well install a different camshaft, a different camshaft and I need Triples. It's a cascading effect.

 

The LD28 would be wasted in the L24 block anyhow, I can get it to 2.7ltr without it. Using a regular L26/L28 crank with an overbore. LD28 cranks are expensive and hard to find, L26/L28 ones you literally have to give away. I'm trying to recycle any parts I have, so I guess it may depend on which crank is in the best shape (L24/L26/L28). If I keep the LD28 crank it would be to build a big 3.1ltr with triples etc..

Fair enough. The L24 with LD28 crank just intrigues me, as a way to maximise displacement whilst retaining original bore size i.e still allowing the possibility for the motor to be returned to stock if desired. I guess if it is not your original L24 then it doesn't really matter however.

If you think a LD28 crank in a L24 is something, LCR is building 'CBRJeff' on here a L24 based 3ltr - 85.5mm bore, with a 89mm stroke crank! ;)

What sort of power at what revs are they hoping to get from that config?

I'm starting to think I'll be going to Melbourne when I'm ready to get my engine done. Goddam they do some amazing stuff.

That rocker cover looks awesome Gav!

I just looked at the bill for my Water-jet basted rocker cover & it was $200 to have done (inside & out). 

 

What sort of power at what revs are they hoping to get from that config?

7k and 290 to 300hp.

There is a reason why Les has SO MANY people from interstate & around the globe getting him to build L-series engines ;)
There is also a particular twin cam head being worked on in there at the moment...

Yep have been following this build with great interest :) is there any merit to building an L24 with the LD28 crank and retaining original bore size for the reasons stated in my previous post? Sorry this is getting a little off topic from original thread..

It's the 260 +/- ft lbs from about 3500 that will make the car.

Right you lot, get your own thread to discuss the virtues of stroker options and their performance. All this talk is like discussing how great booze is in front of an alcoholic. I need pure thoughts of standard L-series rebuilds. Otherwise the tail is gonna start wagging the dog in this engine build.

 

However if you want to discuss L24 porn, perhaps you could discuss the 11041-E4621 (Safari Head) or the LY cylinder heads. Nissan's own LR24 engines. That I would permit.

I'll even get the ball rolling.

Update from the Candy Shop.

 

And boy am I glad I opted for the water blasted finish. I reckon it looks the ducks nuts. You can see how it looked before looking at the Overview Of L6 engine heads thread (the images of the E31 are this cylinder head).
