1/12 Datsun 240ZG

The head is starting to look great, keep us posted. Can't wait to see it finished or even with paint on it!! You got pm.
Many thanks Mark..:smile:
Yes...got a little side tracked with the head....it was not originally in the plan, I just loved the look of it and figured I'd give it a crack...:evillol:

PM replied too, thanks mate. :cool:

Hey Stump, no doubt about it.... still one sick puppy!!!:wink:
ORSM work as always:)

Thanks B. :wave:
Started to re-do the head a little last night....it's still a bit fat. Plus about 4mm too high. :lol: A mate gave me some real dimensions to go by. :wink:

heres some motivation:smokin:

Many thanks AzN 2NR ....
That IS a very kool clip, and yes, I have seen it before..always fun to watch again though....:evillol:

Got some more done yesterday and this morning....
The head is finally taking shape, inlet runners/tubes are made, just need to add a bend to each..

Here is the stock motor set up (on the right) with my spare motor and new head.
Height difference is negligible, so I am really pleased I trimmed the thickness of it...:naughty:

Inlet side. I made 6 adaptors to bolt on here, they will be made to suit Webbers or a turbo...??:biggrin:
http://images50.fotki.com/v406/photos/6/63306/7073322/jan162010005-vi.jpg

Closer look at the new water distribution holes. Flanges added and drilled for tiny bolts.
http://images17.fotki.com/v522/photos/6/63306/7073322/jan162010012-vi.jpg

That's all for now...The rocker cover is shaping up nicely, maybe a pic or two later......
cheers
Greg :aus:

Love it Greg! :wave:

Thanks Bill, she's almost done.....:runaround:

Those funny looking things to the left will become my intake runners...
Just two hollow tubes, siamesed together at one end, then added a bend to each...
http://images50.fotki.com/v1522/photos/6/63306/7073322/jan172010001-vi.jpg

Overall view looking down on the head and cam cover...
The oil cap is from the kit, I just added a hole for it to sit in...may leave it with no glue...

That's it till I get those inlet runners sorted....still a work in progress...:naughty:
cheers
Greg :aus:

Mmm, eye candy.

To be honest, I'll be sad when this is done, it's a pleasure to watch it come together.

:iagree:

Even the oil cap comes off. Reminds me of hiros r32 progress thread. :bananasmi:

Just one word for it.. WOW..



Paul.

This is a very interesting and amazing project. I could learn alot from you in determination and patience. I like how you did the interior holes for weight savings. That will look very trick when it's all painted. I think you have more time in the engine then I have in any of my complete models. Great job you are doing. Fun to follow along.

Thanks so much Bill, Mark, Paul and quadzero..:smile:

Bill and Mark,
That's what has slowed me down I think....the thought of finishing....:p
Never fear....whatever ends up on the bench next......be prepared.........:evillol:
Leaning very heavily towards the 1/12 RX-7....................................:cool: It is just begging for some extra TLC....:smooch:

Lovely job...really enjoying your workmanship!

just WOW.



Paul.

Thank you John and Paul..:p

Been getting some bench time this weekend......:naughty:
Also, had some requests to see how it looked in the engine bay......coming up down the page...

First I wanted to check the hood fit....not all that good. :confused: I had checked it briefly very early on, but never paid it too much attention. :mad:
The fit is horrible. The hood is warped slightly, but it makes a huge difference at all corners....some up, some down....I'll probably display it open. :tongue:
http://images38.fotki.com/v266/photos/6/63306/7073322/OSGikenjan252010009-vi.jpg

Finally got the runners almost completed...just some final sanding and smoothing to go.....
http://images47.fotki.com/v1477/photos/6/63306/7073322/jan242010006-vi.jpg

http://images17.fotki.com/v521/photos/6/63306/7073322/jan242010007-vi.jpg

The Weber/Solex carbs have had their mating surface "machined"..(trimmed with a #11 blade..)
Their flange was molded as one with the manifold flange, so I thinned it down. :smile:
Mocked up, they look right at home hanging off the head....
http://images19.fotki.com/v276/photos/6/63306/7073322/OSGikenjan252010012-vi.jpg

Not a huge amount of spare room in there...the rocker cover actually hits the hood as well, so I''m modifying the sump to allow it to sit lower...
http://images54.fotki.com/v554/photos/6/63306/7073322/OSGikenjan252010015-vi.jpg

And with the amount of time I've spent going over ALL the reference pics I have..the engine orientation did not hit me till I test fitted it....:rolleyes:
It NEEDS to slant the opposite way.................DOH ! :jerking:

OLD motor set-up......
http://images52.fotki.com/v304/photos/6/63306/7073322/headerssystem016-vi.jpg

NEW motor set-up...........
http://images52.fotki.com/v642/photos/6/63306/7073322/OSGikenjan252010008-vi.jpg

I swapped engine mounts from side to side and cut the gearbox off and re-aligned it. :evillol:
Sump/oil-pan modifications are progressing nicely...I'm adding "wings" to it to replicate a baffled high capacity unit. :smile:

More to come guys, thanks for watching..
cheers

Isn't that always how it works? Great work on the engine, can't wait to see it painted, it's really something to look forward to for us. Nice save with the engine slanting. Keep up the good work. Also, couldn't you tweak the hood with some heat or hot water?

Thanks Quadzero...:)
Yes, I will try and save the hood...haven't tried yet, but I was thinking some hot water will help. Cheers man. :wink:

Well, the weekend got quite busy in the end..............:biggrin: We have PAINT !

Engine block. Sprayed Tamiya TS-10 (?), topped of with their new matt/dull clear. It gives a nice dull look..
http://images54.fotki.com/v1592/photos/6/63306/7073322/OSGikenjan262010014-vi.jpg

http://images21.fotki.com/v208/photos/6/63306/7073322/OSGikenjan262010015-vi.jpg

Head was sprayed gloss aluminium, at a distance to try and give the rough cast look...
Rocker cover in matt black, again, it has a semi-rough appearance. The fins are now silver. :biggrin:
http://images21.fotki.com/v208/photos/6/63306/7073322/OSGikenjan262010001-vi.jpg

http://images18.fotki.com/v438/photos/6/63306/7073322/OSGikenjan262010004-vi.jpg

Now, the issue with hood clearances I'll resolve later....for now.............
This is the NEW sump/oil-pan. Bigger, deeper and wider. Cooling fins added too..
http://images18.fotki.com/v438/photos/6/63306/7073322/OSGikenjan262010012-vi.jpg

Comparison beside the stock unit...
http://images54.fotki.com/v1592/photos/6/63306/7073322/OSGikenjan262010009-vi.jpg

This afternoon I added all the bolt heads to the inlet manifold, head and rocker cover.. It's starting to take shape. :p

More coming soon guys..
cheers
Greg :wave:

That looks awesome man, i wish had more time to build so we don't have to so long for updates :P..

Keep up your great work, can't wait to see more..

Paul.

Fantastic! The new twin cam head is just stunning.

couldn't you tweak the hood with some heat or hot water?

Just out of curiosity, has anyone ever done this and had it work? Not at all to be critical, but I think that's one of those techniques that always sounds good and sensible- up until you try it.

Just out of curiosity, has anyone ever done this and had it work? Not at all to be critical, but I think that's one of those techniques that always sounds good and sensible- up until you try it.

I have used the hot water technique loads (see my Nissan Silvia thread!). Some model plastics are a lot more flexible than others and a lot more easy to re-shape. I have experienced a couple of occassions when the plastic has strated to split due to too much bending but it was usually progressive and therefore any un-repairable damage was avoided!

Just realised I should have mentioned that this is a fantastic thread with superb quality work! The Datsun 240ZG is looking stunning so far!

Thanks guys..:naughty:

MPWR and Viccario,
I gave the hood a bit of a tweak, it didn't require a lot....but it was enough to annoy me. :rolleyes: :iceslolan
But it appears to run a little deeper than that.
The hood now rests with all 4 corners touching my bench top, so I must have glued the front end not square or true...:banghead:
I will carefully unpick it a re-do the front parts....:runaround:

Also spent the weekend re-doing other parts...:uhoh:
I had something bugging me with the rocker cover.....:screwy:
Last week I contacted a person in Japan (Mechanic shop owner) who has worked on a car equipped with an OS Giken head.
He very kindly emailed back with lots of excellent detailed photos to help me. :1:
Fresh with new reference, I shaved another 1.5 - 2mm off the top of the cam cover, the bulky part which covers the gears.
This allowed me to finally add the OS logo which has been missing, plus some extra hood clearance...:iceslolan
http://images17.fotki.com/v521/photos/6/63306/7073322/OSGikenjan312010003-vi.jpg

After a re-paint...also the stabilising bar added to the inlets.
http://images20.fotki.com/v533/photos/6/63306/7073322/OSGikenjan312010014-vi.jpg

Carb linkages added as well...
http://images18.fotki.com/v437/photos/6/63306/7073322/OSGikenjan312010019-vi.jpg

Dipstick....
http://images20.fotki.com/v533/photos/6/63306/7073322/OSGikenjan312010008-vi.jpg

Aside from a few other little tweaks, that's about it this week....
With some luck, once I reset the front end sheetmetal, my hood clearance issues will disappear....:rolleyes: :icon16:

More soon guys...
cheers
Greg :aus:

This is amazing work, can't believe the realism and details. The OS logo looks like a molded on part. How you got the cooling fins on the pan so straight and parallel is beyond me. Good luck on the hood issues.

WoW
the pan and the valve cover are amazing...i can hear the Datsun fans cheering

Thanks so much Quadzero and 675datsun..:tongue:

Hasn't been a lot of activity here of late, but I did make a new set of headers..

Started adding detail to the block, water bypass pipe added, mesh hose painted matt black.
Also have the oil pump and adaptor in place, ready for connection with a cooler..
http://images20.fotki.com/v528/photos/6/63306/7073322/OSGikenfeb072010005-vi.jpg

Start of the new headers, made from 3.2mm solder.
http://images44.fotki.com/v1419/photos/6/63306/7073322/OSGikenfeb072010007-vi.jpg

Done....almost.
http://images22.fotki.com/v817/photos/6/63306/7073322/OSGikenfeb072010014-vi.jpg

Bolts added, also added to the water pipe along the head...lotsa bolts.... :shakehead :tongue:
http://images52.fotki.com/v8/photos/6/63306/7073322/OSGikenfeb072010033-vi.jpg

And getting ready for plug wires....took forever to nut out how I would tackle this...
I ended up making a punch from brass tube, punched out some .005 inch sheet.
The result left me with six nicely domed tops for my plug towers..:naughty:
http://images47.fotki.com/v1588/photos/6/63306/7073322/OSGikenfeb072010003-vi.jpg

Take no notice of the yellow leads....not for this build....:grinno:

More to come soon guys...thanks for hanging around.
cheers
Greg :aus: :wave:

:eek2::eek2::eek2::eek2:. That's the only thing what i can say..




Keep it up Greg, would love to see your engine done.

beautiful car and build.


Paul

this build is looking awesome, I love all the detail, especially on the engine!
Man I would love to build a 12th scale car, you can fit so much more detail in something a little larger.

great job again, and I can't wait to see this project finished.

Steve

Looking great!! Are the tire/wheels still for sale?

Thanks so much guys...:wink:

Paul,
I'm getting a little anxious myself.....waiting on some parts to arrive...
Even started piecing together the motor for my "stock" 240Z build to help fill in time....:lol:

Steve,
If you get the opportunity to get your hands on a 1/12 kit, go for it mate...You will have so much fun it's not funny....:naughty: :wink:
(Darn it....I just bought myself another one this morning............:disappoin :lol: )

Jmpsebring,
Cheers mate. :)
Yes, wheel and tyre packs are still available man, just PM me if you like.
AUS$49 plus AUS$12 postage Worldwide.

cheers guys
Greg

Hello all,

Well, the small amount of work started on my second (stock) build has escalated....:evillol: Oh, but I have started to detail the triple Solex carbs for this build as well...:naughty:

The stock version will be built along side the other, so I haven't worried about a second thread...
Initial work began on the exhaust system...I had used several key components on the modified car, so.....I began scratching up a stock system.

First version was a twin pipe, twin-tip.....
http://images51.fotki.com/v177/photos/6/63306/8487227/stockzfeb222010023-vi.jpg

However, most reference show that a single tip would be more accurate....so I then made that.
http://images53.fotki.com/v546/photos/6/63306/8487227/stockzmar182010007-vi.jpg

The single tip will win out in the end I feel....:smile:
Motor reference also show a heat shield fitted to the manifold, a part Tamiya did not add...
I made a basic one from .5mm sheet, added some ribs and bolted it in place.
The carb linkage mounts were also added at this time.
http://images42.fotki.com/v1380/photos/6/63306/8487227/stockzmay102010006-vi.jpg

http://images53.fotki.com/v535/photos/6/63306/8487227/stockzmay122010009-vi.jpg

And reworked some detail on the SU carbs. Added a choke cable mount and lever/linkage plus some extra fuel lines.
http://images53.fotki.com/v536/photos/6/63306/8487227/stockzmay162010006-vi.jpg

Once they were mounted, I added extra fuel line connections, vacuum hoses and it was starting to take shape....
http://images39.fotki.com/v1285/photos/6/63306/8487227/stockzmay182010007-vi.jpg

I wasn't satisfied that I would be happy using what Mr. Tamiya supplied for the main fuel line either...:uhoh: I is quite prominent at the top of the motor...
So, I made mine from .7mm solder. I added a couple of brackets and fuel junctions to hold it all together.
It is bolted to the front engine cover and a bolt on the rocker cover.
Tamiya's version in the back ground...
http://images12.fotki.com/v532/photos/6/63306/8487227/stockzmay182010001-vi.jpg

From there, I made some mods to the air cleaner...
Adding some extra connections for vacuum lines and making an air cleaner element fro hi-density foam.
http://images116.fotki.com/v706/photos/6/63306/8487227/stockzmay252010003-vi.jpg

http://images12.fotki.com/v531/photos/6/63306/8487227/stockzmay272010007-vi.jpg

Finally, some plug leads....plus an extra hose or two.
http://images116.fotki.com/v1596/photos/6/63306/8487227/stockzmay292010011-vi.jpg

http://images12.fotki.com/v252/photos/6/63306/8487227/stockzmay292010010-vi.jpg

There is still a few touch-ups to take care of....but it's getting close.....
More as it happens..( to both builds. :) )
cheers
Greg :wave:

Holy crap......embarrassment +++ :redface:
How long since you guys got an update......? Hmmmm....Here we go then. :)

First up, the "stock" version.
Basic fuel and brake lines run. Done. Started at the rear.....
http://images56.fotki.com/v1600/photos/6/63306/8487227/stockzjune06a2010010-vi.jpg

Including a new fuel filter I made up...the kit part looked to awkward or weird....??
http://images116.fotki.com/v1596/photos/6/63306/8487227/stockzjune082010003-vi.jpg

I made some brackets and linkages for the firewall, they will connect to the throttle linkage eventually....
http://images19.fotki.com/v1612/photos/6/63306/8487227/stockzjune132010003-vi.jpg

Added some extra hoses to the motor. Just the heater hoses....Had to re-route my thoughts with these, as my reference showed mixed methods of running them.
I think they will be ok as is.....
http://images112.fotki.com/v584/photos/6/63306/8487227/stockzjune11a2010004-vi.jpg

And finally, an overall look at the bottom. Motor in place, along with the single exhaust system. :)
http://images54.fotki.com/v202/photos/6/63306/8487227/stockzjune112010009-vi.jpg

Then, an update on the modified 240.......
After several agonising attempts at plug leads, I had success....:p
And many.....many hours of testing, cutting, re-testing........I had the carbs ALL linked up..:runaround: :tongue:

http://images19.fotki.com/v1612/photos/6/63306/7073322/240ZGjuly042010009-vi.jpg

Work is still (kinda) progressing, all be it slowly......
I've started to modify the guards to fit the over-fenders a little higher than stock.
This will enable the car to sit a bit lower too....which is what I was hoping to achieve....:evillol:
I'll update as soon as possible guys, and truely apologise for the delay....

cheers
Greg :aus: :wave:

Wow! I love just how much detail you've put into this. Seeing those carb linkage pictures I can imagine hearing it revving already!

The wait was worth it I think. I almost have to laugh when I see this wip I enjoy it so much. The throttle linkage is amazing but really all your work is. This will be an incredible model, if you can even call it that now when it's finished.

Hmmm..very nice...Keep it up!

That engine is just so realistic, its incredible work

Stump, your work is exquisite. When this little beauty and the 'stock' one (haha stock, yeah right) are finished, you will have to tell us where they are to be presented to the modelling judges. Must see this in the flesh.

NICE! I can't believe how much detail you're adding. The tiny jamb nuts on the throttle ball links blow me away. I've never owned a real Z but after reading this thread I'm pretty certain I could work on it without the manual.

hey greg, any update of this beast is worth waiting for. keep up the awesome sausome progress.

GREATEST JOB EVER.

Congrats on the job so far.

Cheers,

Gus

Utterly gobsmacking. The detail work is stunning.

Truly fantastic work Stump. Those carb linkages are outrageously good and I'm loving this build!:smokin:

any news?

Wow, incredible build! I love how all the details are coming together. I especially like the OS on the valve cover. The linkage for the throttle body is just gorgeous! I am sure it would fool people!

Thank you ALL so very very much guys..I'm pleased you haven't lost faith and interest...:)
Believe it or not......I HAVE been doing a bit on it this last couple of weeks.....:eek7:
Not so much that it has garnered a photo shoot, but little bits none the less.....
The driver/race seat has started to get modified. (Porsche 934 spare) I shortened the back and bolstered the top corners.
Plus I made a "sliding" rail assembly....not very to "scale", but it WILL slide....:screwy: :rofl:
And made some adjustments to the cage...a couple of the bars were not lined up correctly, they are now. :)
Hope to have something worth getting pix of soon....
cheers
Greg :aus: :wave:

I haven't checked the forums much lately.. and am kinda glad I haven't missed anything! Hah.. I'll probably be using your thread as reference when I get back to mine, which hopefully will be sometime this year.

Cheers mate. :thumbsup:
Aye, things have slowed to a crawl....was starting to experience "Datsun burnout"....:lol2:
It surely isn't forgotten though, and hope to get back to it soon enough. :wink:Working on a couple of drag cars to break the boredom. :iceslolan

Guys, sorry for such a delay....never expected to be so withdrawn for such a long while...:shakehead
However, things are on the up. :iceslolan
A little over a week ago, I got the Datsun out of storage and began to get highly motivated once more...
As I have 2 of these large 240's on the go, soon to be joined by their 3rd brother, I shall keep all 3 in this one thread to make things easy.

Plans have been altered along the way too, with plenty of time given to consider my options, I have re-arranged most of my photos in my Fotki albums.
There may be a few still incorrect to their build, but they are few. :)
The main changes are to do with motor swaps, but I hope these changes will only be seen as a positive move, and trust that you will still enjoy the ride as much as I do. :)

The blue car (original build) will now be getting a turbo'd RB26 from a Fujimi GTR. :evillol:
The "showroom" stock build now gets the OS-Giken motor, to be replicated (close) to the TOMITAKU version.
The 3rd will be a stock 240ZG "wide arch" model. (slight mods of course....:iceslolan)

So, this passed week my attention has been towards both turbo and Tomitaku.
I started by adding a modified fuel system to the TOMI car. An inline pump/filter was made, then I ran a fuel line to a fuel block on the inner front fender.

http://images15.fotki.com/v588/photos/6/63306/8487227/DSCF8611-vi.jpg

As the interior will require mostly stock components, I started making some seat belt hardware.
I have some surgical tape which I hope will become a better seat belt than my "trial" version. :uhoh:

http://images9.fotki.com/v131/photos/6/63306/8487227/DSCF8640-vi.jpg

And I have started a basic roll cage.
Driver seat is from the Fujimi GTR and will have a race style harness.
http://images43.fotki.com/v398/photos/6/63306/8487227/DSCF8644-vi.jpg

This is my plan for the turbo-charged version....
http://images45.fotki.com/v148/photos/6/63306/7073322/stockzjune202010004-vi.jpg

But.......................stock, it will not be. :iceslolan :naughty:
So, after a long session searching reference, I decide on a semi-race look.....
I made these to begin.

You may see, I have also altered the cam cover, deciding on two separate covers instead.
Here is an overall photo of some of the parts being used/made.

So, with some luck and time to work, I sure hope these builds keep me busy for a while. :)
I hope you like and approve my decision to change things up a bit.
Thanks for stopping by, and please ask questions if you have any, critique is also highly valued.
Cheers
Greg
