A15 is still in production.

D while I always enjoy folks who tinker like our friend who does many race car fabs but does the most out there bits for himself: his Pinto wagon's all in one speedo/temp/mileage/tach/ air fuel ratio gauge pack fit into the stock speedo hole with custom backlit facia, his aim isn't to make something worlds better but to simply work out an idea..............he's the kind of guy who will restore a car but has no real interest in driving it after it's up and running.........he's off to work out the next idea.

Now as for A sereis blocks going away, I don't see that as they are still in fork lifts and haven't been out of production in road cars for that long. Of course I've kept a spare block for myself.

The 1000 2 sdn gave me the largest loss of years of my life, a temporary 13b that on my 3rd drive ended up in court for some offences Im not proud of and neither was my wife so I didnt jump all over the forums about it as I was reminded often of that achievement by more than one person both non and related.
The other engines I gathered where many for that project but now finally a ca18
will be the final conversion. (I went from A10>A14>fiat>Daihatsu>Rotary>Suzi>CA18)
Not counting trial fitment of the ally Peugeot 2.2 or the Cossie I never importd but bought.
Sidedraft ended up with my old KB10 it started with the A10>2xA16> A12 all 5 speeds
quad carbed and Sigma GE brake conversion. The 1608 cracked bores twice.
Those where just the 1k datsuns I played with not the countless makes of cars Ive
come across over 26 years.
On other make of cars and bikes Ive had over a hundred but the completed ones that
stand out are not appropiate for this site but a caterham replica, 67 pagoda w/ 6.3 litre and Vw shortpan Manx where my weirdest 4 wheelers of all not really for this site. Weird in that the 7 had a daihatsu HD motor with supra box, the Pagoda 1 of the largest factory dry sump engines instead of a 6 and the Manx an Alfa Romeo Boxer before
going back 2 a stroker Combi setup.
My treasure was a BSA Royal Star from the year of my birth, restored for 11 years as a
side thing and stolen not long after its first show and shine and never recovered.
I can tell you bitter is not the word that comes to mind everytime I think of that bike
long with the BSA c11 and Bamtam (also restored) that went with it on a saturday night.

Yes you can buy some incredibly old machinery if you look hard enough but I believe
the A series is an engine used in more than one make. Ive seen them re-power everything
under the sun and the larger capacity ones are already starting to fetch good prices.
The owners have always been "mainly" not all tight butts :) and if the bodies dont survive
like other cheap skate classics (eg Austins and Morris) then i dont see them sought after
much unless you want to re-power or restore a modern forklift.
The early A series are available but usually end up crushed or given away.
The cars they come in themselves are modified with late motors like I myself am doing
to one of them for now. The other 2 I have will remain A series.
They are not a significant engines like the Caddy or even the Kent but I feel this and
many other reasons why both the engine and the coupe bodies will be rare.
If they dont become rare then Ill be very happy as day by day I adore them that much more.

Ill show other photos my VB10 its almost finished to my liking...Ive already put some pics up of it somewhere. Its the Pano version with now with a fussy detailed a12 (a10 in storage)
Saturday I decided to change the alternator to a new type with internal regulator and fan yet couldnt get it finished and had to go back to the old setup. If someone helps me with the link to a thread on here somewhere I will try again. All for aesthetics as i hate the
external reg and fan on all alternators and especially hate (a big word i know) generators
they spoil all aesthetics on engines of yesteryear.

Pugs and BMW use the all alloy Diesels, Pugs having them for years before any other make.
The PSA HDI has just hit the 10 million mark.

I don't know of too many alloy diesel blocks

You have some great crazy ideas D
Alfa diffs
Wierd gearboxes
Way out engine designs

What have you completed that you can show us ?

And as far as scarce A series... nope
I would think a V8 flathead Caddilac motro... or even their V12 or V16 cousins would be alot rarer due to the very small number made
But guess what
I could lay my hands on at least 3 of each if I was to try hard ... and thats just in far off Australia where they didn't have too many
So if I can find a 1930 Caddy engine that wasn't brought in here...I'm sure when I'm ready for the pine box there will be plenty an A series to rev at my funeral

Yeah alot of closet mardigras like complexes, lets leave it there!

In terms of simplicity and performance there is little to fault an A series.
More modern engines are complicated, harder to maintain and rebuild.

I believe bio-fuels will be entrenched in our future from bacteria or algae type
organisms and bastards like Agri-Corp Giants (eg Monsanto).

Will we be driving our own billet blocked bio-diesel/alco retro customs in the
future? Only possible if CNC billet alloy blocks become affordable.
Either way It will be great to look back if we are lucky to live to old age to
reminisce about what crazy things we thought.

Why do people want engines in their arses? WTF is that supposed to imply?

When these are rare, we won't be driving anyway (or driving fossil fuel powered cars anyway).

not sure what the whole point of this thread is, but if A-series engines ever become so rare that is it cheaper to make a new engine block out of a billet of aluminium I'll swallow one up my arse too.
The crazier thing about this pie in the sky conversation is to think that even if that did eventuate, why the hell would you even bother? Why spend tens of thousands to recreate an A-series when you could just get something newer, better and cheaper to do the job?

If I had more time on my hands I would convince and help my nephew to CNC such
a block at his mechanical engineering campus before he transfers to Robotics.
Whatever you want to stick up your pie hole is your issue.
Mark my words the A series will become rare in our lifetime.

edit: Thanks for the input on cost breakdown, there is a place in the state
that does billet blocks for cheaper. Im not saying its affordable for every1
but I remember the same thing when i first started using Apples, Silicon Graphics workstations and color laser printers. Who would have thought a 150,000aud a4 color
printer could be bought so easily now for so cheap?
3d is not comparable to 2d but who knows what lays around the corner?

That's a big (and very hungry) anus by the sounds of it!

You clearly have too much time on your hands
If the A series ever becomes rare in my lifetime and billet machined cosworth blocks become commonplace I'll swallow one up my anus
OHC or DOHC won't matter then when its turning 10k rpm using my poop as a lube
