Yeh its very tempting just for laughs, Individual constructed vehicle is a whole world of bullshit. Better off building your own kit car and putting a fibreglass datsun body over the top...

Would be fun to just dump it in and drive around for a while...
...but I'm pretty sure there are severe penalties for doing that these days :D

So I just received my spare 1uz motor today, and it just so happened that the datto has its motor out at the moment.

I knew it would be close, but I didnt think it would fit so well.

Got a couple of photos for anybody else thinking of something crazy like this.

Bear in mind the following:
- It is just hanging from a block and tackle, its too far toward the drivers side, its also rotated.
- There is no sump on it hence why its not lowered right down (dont want to scratch the sump face or rotating assembly) But there is a lot of room below it, id guess it would fit under

the bonnet if dropped in completely.
- There is a bit more then an inch of clearance at the firewall end as it is pictured.
- I'd guess a few inches clear between valve cover and strut towers each side.
- you could use the normal water pump if you modified the radiator support.
- if running an electric water pump i think you would get away without rad. support mods.
- theres a surprising amount of room for headers. (Will get more photos in daylight if anyones interested)

I am very doubtful any state would allow this to be passed for road use, but anyone looking to build something for track/strip/fun with arse loads of power potential and keeping it all

Japanese it might be a goer.

Enjoy...

Yeh wurzel the manifold is yours if you want it, ill find out how much for postage. PM me your details etc.
its quite rough but i think youll be able to either clean it up and muck around with it or chop it up and use it as a guide to make a nice one...

I too started off knocking up designs in 3D then I bought a mig and 'silver pigeon sh!t' welded up stuff like that for practice.
The ole gasless is not much better then stick welding but will get you outta the sh!t until you can get a wire/gas setup going.

Another thing consider when knocking up a 3D design is to adhere to the already available mandrel sizes, shapes and radiuses.
Model the common bends first then you can make some presets for use in your design.
Otherwise you may need to get pipe custom mandrel bent (expensive not to mention there are physical limits as to what minimum radiuses can be bent)

Heres a bit of inspiration for ya:

To be honest I dont think it matters too too much, sure for absolute peak horsepower blah blah yes it would help.
but really if you want all out peak horsepower why have you got a datto? :D

I think the best bet is to position the carb in a practical location, bolt the carb plate onto the carb, bolt the manifold plates onto the head, then join the dots. Keep in mind the air/fuel will 'slow down' around corners so less bends is better.

I basically tacked it together then got the air compressor and blew air into each runner and tried to get a 'feel' for how it was flowing, moved bends here n there until the air coming out the port holes felt about equal... not very precise i know but it does give you an understanding of whats going on in there as you change it.

Start by making the port divider, make them as symetrical as possible and tack them on first, all the rest can be moved easily.

Best thing about using mild steel is it is easy to weld, cheap to modify, 'softer' to work with then stainless etc
Just play around with it and see what works best.

When your happy with it, make it out of stainless or alloy.

If you decide to go with a stainless final version, you can tack it all together using mild steel wire (or gasless), just put as few tacks on as needed and try to put them in easy to get to places, that way when you take it in to a welder/ fabricator all they have to do is put their own stainless tacks on then grind yours out and weld.

can save you a lot of $ on labour etc not to mention practicality.

Obviously this rapid prototype method doesnt suit everyone, but not everyone has a TIG and milling machine in their shed.

There is a bloke coming to look at my A15 motor this weekend, if he doesnt want the manifold you can have it to play with or dissect etc, as I have no use for it any more (sold the carbies)

Hey mate, you could always knock something up yourself.

I made a single sidedraught manifold for my A15 using only a drill, grinder, die grinder and gasless mig wire.
Although i made mine out of mild steel (only a test after all) you can do all this with stainless if you plan on keeping it.

I got 10mm thick mild steel manifold plates waterjet cut, cost $60 (take in your standard manifold for them to trace)

I used alumanized mild steel (exhaust pipe steel) 1.3/4" / 38.1mm.
From memory I simply squeezed the pipe in a vice and it lined up EXACTLY with my ports although mine were slightly larger then stock oval port, you are handy with a dremel so just grind the 10mm plate so theres a smooth graduation to the head.

for the bends buy a couple of 180 degree mandrel bends from an exhaust shop.

You may find you will need to rotate the carb toward the front of the engine bay for clearance, (i had a dellorto 45 with intake trumpets in a 1200 ute and there was no room)

as you can see in the pics i roughly equalised the flow by making the shorter path having more curves and the longer path straighter, the seat of pants dyno said it was pretty close anyhow.

To add a vac hose nipple (for the dizzy) i just cut off some old brake line, drilled the same size hole into one of the tubes and welded.

All in all it came up pretty good, very fast throttle response, good power throughout the rev range, although I have not compared it with a stock A15 I'd say it works very well.

If you are interested i can take some more photos of it or give you more info on how to make the tricky bits like the intersection of 2 ports into a single tube.

Good luck.

Have a pair of Dellorto 45's for sale.
2 carbs, 1 complete and still on a running engine, other dismantled and cleaned ready to be rebuilt.
Includes 2x Full rebuild kits, Manifolds, linkages, ramtubes etc
Average wear, tear and corrosion for age.

Also listed are the left over parts for a EFI conversion (hence the sale of the delos)
Have two complete quad throttle body sets, including all injectors, tps, air sensors, plumbing etc.
Both of the sets for sale can be easily split in the centre (IMPORTANT IF ADAPTING TO A SERIES ENGINES) so that you can space them apart to clear the centre exhaust ports.
Both are in very good condition and I had to scoure the wreckers to find ones that would be able to be used for a datsun conversion.
I still have a set that im currently making manifolds for.
Also listing soon a spare megasquirt 2 kit.

Dellortos: Dellortos
Quad throttle bodies
R1: R1 Throttle Bodies
ZX636: ZX 636 Throttle Bodies

ITEM:
2x Dellorto DHLA 45 Carbies
1x Manifold to suit oval port head (A14 / A15 / GX)
1x Linkage setup
2x Rubber soft mount kits
2x Rebuild kits for carbs
4x Ram tubes

Has the 30mm chokes already installed and I was told jetted to suit a mild/warm A15

Condition
Used / average
could do with bead blast or equiv.

Have had these carbs installed with manifold & linkages on engine and seemed to work fine.
Removed them due to mistaking a damaged dizzy for poor tune of carbs. Unfortunately they never made it back on to the engine so I cannot tell you how they preform on the road.

One carb is still on my ute mounted to a single carb manifold that I knocked up.
Works fine without problems (single manifold will be given away with carbs)
The other carb has moderate corrosion, started to clean up ready for rebuild.
Thats as far as I got due to building quad throttle body efi setup and losing interest in carbs.

PRICE

Best offer.
Prefer to keep these in the Datsun community rather than ebay them.

Photos
We all know what they look like but if anyone is seriously interested ill take some photos.

Thanks mate, will save me a fair bit of time.
And cheers tnpshow for making that available!

Hey fellas.
On the old site somebody had posted a cad drawing of intake manifolds for A series?

I cant seem to find it with the new search...
anybody know where I can find it?

Bout to make a new manifold for the fuel injection conversion...

Thanks
