1971 Nissan 240Z Fairlady - Alternate build of 42056 Porsche 911 GT3 RS




One of the most desirable cars to ever come out of Japan is the 1975 Nissan 240Z Fairlady and if you already own set 42056 Porsche 911 GT3 RS then you have all the parts you need to build one of you own! 

The MOC has a working 5 speed H pattern shift gearbox that's based on Mr Woo's excellent design and you can upgrade this to a 5 speed and reverse option if you add the part 32187 Technic Driving Ring Extension. This part is not found in 42056 but is easily obtainable via Bricklink. It can also be found in many other sets so chances are that you might already have one! Both options are included in the instructions.

The bonnet opens, as do the doors with working doorhandles and latches. Under the bonnet you'll find an inline 6 cylinder engine that's connected to the rear wheels via the gearbox.

Engine bay details include twin carburettors, performance air filters, exhaust manifold, distributor, radiator and a battery. Just to the left of the engine in the image above you can see the connection point for the HOG steering. The HOG wheel is tucked away discretely beside the passenger seat when not in use.

Inside the cabin there's an adjustable angle steering wheel on the right - I'm from Australia and the car is from Japan, both countries have right hand drive cars and we drive on the left side of the road. The wheel is 2.7 turns from lock to lock just like the original and there's plenty of legroom and even pedals on the driver's side. 

The wheels from the Porsche set may not be 1975 factory spec for the Fairlady but they do suit a street modded JDM style very well and make the car look more purposeful. 

To go with the wheels (and limited number of orange parts available) I've added a black bonnet and front spoiler.

Underneath you can see details of the drive train, rack and pinion steering and independent suspension, but don't expect too much travel in the suspension before hitting the guards!

The Fairlady is a little lighter than the Porsche and also a little more compact.
Dimensions:    50 cm long x 22 cm wide x 16 cm high
Weight:            1.85 Kg
Part Count:      2071

The instructions run to 629 pages with 597 steps and are generated Bricklink's excellent Studio program. 
If you've seen my previous work you'll find that they're also easier to follow and more refined. You can get a sense of the build by downloading the first 42 steps for free here.
This will build the gearbox which is slightly different to the one used in my Lancia Stratos MOC (also an alternate build of 42056) and you'll get a good idea of what to expect before you go ahead and purchase the full build instructions. I also think the trickiest parts of the build are in the gearbox, so if you can build that you should have no trouble with the rest.

I hope you have as much fun with this one as I have and I look forward to seeing what mods, tweaks and additions the Rebrickable community brings to the party!


I made a small mistake with the year of manufacture of the subject car and have changed the title of the MOC and the first page of Part 1 of the instructions to correct this. If you have already downloaded and don't mind having 1975 instead of 1971 on the cover then you're all good. If you prefer you can download the file finishing in "edited_year_of_manufacture" and have the correct date on the first page.

Part 2 has been revised to strengthen the front left suspension mount and stop the car sagging. This was a change that was missed from the first instructions and wasn't apparent until my test builder returned the model and I had a chance to check it over. If you have already passed step 395 don't worry. The area is accessible once the build is finished, just check step 398 for placement of the extra connector pin and change in Technic liftarm.

Part 3 step 516 has been revised to make attachment of the headlights clearer.

    how did you know the fairlady is my dream car! just building it now and i am really enjoying it. great work, dude!
    your building techniques with that limited set of pieces is outlandish and fascinating in comparision to normal lego :D  how do you even think of such things?
    just one thing: a little hint at the beginning of the manual to use the stickered up pieces where they dont stick out would be great (or i did i miss this?). i don't really want to remove them.
    • 13 hours ago Pleasedontspammebro Level 10 Designed this MOC DESIGNER
      How Did I know it was your dream car? Well - I guess that we both just have very good taste in the classics!
      That's a good point about the stickers - I really don't like stickers on LEGO so I rarely use them. I'll need to start accounting for them in future.
      I'm glad that you're enjoying the build.

    Maybe you've seen it before. Maybe there is nothing you can do about it. But take a look at this. Meanwhile the complete kit is available at Aliexpress.

    That's a shame.


    Best regards from Germany,

      Hi Florian,

      Yeah - there are a few of these out there now.
      It makes me sad that people are ripping off LEGO and to a lesser extent those of us that sell instructions for our MOCs.
      I think that there is still quite a bit of stock still from when Lepin was shut down and all of these "boxed set" MOC rippoff guys are trying to sell that stock off.
      I'm hoping that they will all go away once the old Lepin bricks are all sold - that is if the Chinese government actually shut them down like they said they did.

      In the meantime - let's keep on making with the good stuff!

    Just finished building this iconic car of the 70's. I don't know what's more impressive...the fact that this model looks better than the Porsche...or the fact that you managed to create this beautiful built with the restrictions of the original set. Looking forward to your creations with the Bugatti set ;)
    • 3 months ago Pleasedontspammebro Level 10 Designed this MOC DESIGNER
      Thanks Mate!
      I did just buy the Bugatti, it was on sale here for 20% off so I really had no excuse not to.
      I'm starting to think about what might look good in those colours and having a silly amount of cylinders to use in the engine leaves me many options! 
      I think that I'm probably going to stay in the 60s and 70s, so many iconic cars made in those 2 decades.
      Don't hold your breath waiting - I'm crazy busy with my work until next year:(
      • 3 months ago Scoot78 Level 5
        The Bugatti Will be under the Christmas tree this year over here. If I had the skill and patience needed I would really like to build a GT40. combining the bugatti and prosche set to create a GT40 in gulf livery would be epic.

    Hi, just finished this car, and it’s lovely. I did not like the Porsche kit much, so it has been in the loft for two years, but when I saw this, I knew I had to rip it up. This is the first technic set of some size that I build, so thanks for excellent instructions! The car is now going on display at my wifes job, a Nissan dealership in Trondheim, Norway. 😃 One thing: In the instructions, step 146-151 in the third part, are just grey. Is that ‘by design’ or sould I download it again? Anyways: great work. And hope that you make an alternate model of the Bugatti as well.
    • 3 months, 2 weeks ago Pleasedontspammebro Level 10 Designed this MOC DESIGNER
      Thanks for your kind words!
      I had not noticed that there were some blank pages at the end of the instructions, I think that this was where I had originally tried to put a parts list but removed it because it was a little glitchy and then forgot to remove the blank pages. I'll update it shortly.

      Im very excited about the Fairlady going on display at your wife's work! Please upload photos!!

      The Bugatti set is one that I'm planning on getting and I'll be making MOCs for that as well - maybe next year.

      • 3 months, 2 weeks ago Webizz Level 6
        Hi again, if it was "just" the parts-list, then it's no problem, since I had all the parts, except the one needed for reverse. Luckily I have AFOLS in town that could help. :-)  I'll be uploading photos as soon as it's on display.
  • 4 months ago kameiv Level 9
    Another awesome model. Reasons are:

    • The inline-six engine (not seen in any LEGO set). I like your engine ideas.
    • It is a big model, it took me about 7 hours to build (totally worth the money).
    • Building instructions are very detailed, clear and of high quality (no brute force needed).
    • The bodywork is very solid. Opening mechanisms for hood and doors work very well.
    • Nice details like battery and window opening handle :)
    • No issues found this time.

    I hope there will be another great MOCs of yours.
    • 4 months ago Pleasedontspammebro Level 10 Designed this MOC DESIGNER
      Thanks for the kind words mate.
      By the gods you work fast!
      Just a couple of days ago you built my Stratos and already you have made my Fairlady.
      I’m afraid that it will take a little while before I come up with a new MOC but I promise that Rebrickable will hear about it first.

  • 5 months, 2 weeks ago Crazy_Borg Level 8
    Finished the MOC yesterday.
    Looks really stunning, just have a few suggestions for further improvements:
    1.) I put the white clutch gear on the differential instead into the steering system. Steering is quite heavy because of the wide tires, the gears of the horizontal axle are slipping quite often. Maybe there is some room for improvements.
    2.) Step 141 is physically impossible. You have to remove parts of the front suspension to fit it in there
    3.) Power transfer from gearbox to engine has to much flex. So I replaced the 10928 gear with a 32270 on Step 114 so you can move the larger 32269 on the gearbox output shaft closer to the gearbox (Step 184). There should be one 32270 gear left over so no problem.
    4.) I removed the exhaust hoses on the engine, they were bended too much so one ripped. Not missing much because they are difficult to see anyway.
    5.) I switched the double-pin with center hole (87082) inside the fenders holding the mirrors with single-pin ones because stress on the fenders. I then put the double ones behind the doors on the rear fenders for the short soft axles guidance.
    It is absolutely beautiful, and the car is really sturdy and well designed.
    • 5 months, 2 weeks ago Pleasedontspammebro Level 10 Designed this MOC DESIGNER
      Thanks for your kind words!
      I have not found the same problems with the steering and power transfer but they are a bit twitchy, I recommend making sure that each component is not too snugly fitted and spins freely. 
      Set 42056 only has 8 of the 32270 gears so I'm not sure that you can make the changes you mentioned without having an extra - I'll look into it.

      The rest of your changes are sensible - I always love seeing what people do differently!

      I cannot claim credit for the "absolutely beautiful" part -  Datsun made a gorgeous vehicle!!
      • 5 months, 2 weeks ago Crazy_Borg Level 8
        Hmm, you are right. Seems my chinese white GT3 came with a spare 32270 gear, thats why I had a leftover. But you can for example use the last 32270 from the hands of god steering knob and switch it out there with one of the unused 94925.
        As far as I can tell once the front tires are off the ground the steering is light and easy. Both gears on the vertical axle of the steering are "hanging free" on the outside with no guidance behind them. So they are prone to slip once higher torgue is required. Also, I put in the 3L axle with stop on step 386 the other way around, because the small 6589 gear kept slipping off the end of it.

    Thank you so much for this it's one of my all time favourite cars. Now I have to order another Porsche kit to build this. Can't wait to get started.
  • 5 months, 3 weeks ago kahless1980 Level 9
    Hello Pleasedontspammebro
    Thank you, for your verry easy Instruction. Wonderful car! 
    I would have a "small" request: the length specification for the installed axles would be very good.  The 1: 1 statement is well meant, but not very helpful in a print or on the tablet.  so it's aso it is an indication of value that I have to estimate and mistakes happen in construction.
    • 5 months, 3 weeks ago Pleasedontspammebro Level 10 Designed this MOC DESIGNER
      Hi Kahless1980,
      Thanks for your kind words - I'm really glad that you liked the MOC!

      You make a good point about axle length, my laptop screen resolution must be about right because the 1:1 scale measures were accurate enough for me that I didn't notice the issue.
      Thanks for letting me know, I'll include the update in the next edit when I tidy up a couple of non-critical issues that other builders have found.

  • 5 months, 3 weeks ago Dutch260Z Level 6
    I've just finished building this MOC over an extended 4 day weekend and it's a brilliant peace of work. During the process I've had many occasions where I was wondering how this was ever going to fit, work, be stable or strong enough but a few pages along and all would come together perfectly. The designer is nothing short of a genius and this becomes even more apparent if you decide to change anything. I did, I tried to convert it to left hand drive and it was a challenge to say the least. At this moment it became clear to me how incredibly difficult it is to create a model like this, so many parts need to come together in just the right way to make this car look like an S30! With all the function and detail that is crammed into the 2000+ pieces there is very little wiggle room. So, if you want left hand drive, start with mirror building the gearbox, engine and frame and save yourself a few frustrating hours. Many thanks to the designer for investing the time and effort to bring this JDM classic into the Lego world. If I could rate this MOC it would definitely get 5 stars. 
    • 5 months, 3 weeks ago Pleasedontspammebro Level 10 Designed this MOC DESIGNER
      Thanks Dutch260Z,
      I'm blushing a bit from your kind words, glad that you enjoyed the build.
      Also, the mods that you made are awesome! This is the reason that I make MOCs, to encourage people to make their own designs and you've done a fantastic job. Very brave to go for a left hand drive variant given that most of the build is not symetrical and you still wanted the exhaust and carburettors on the correct side of the engine. Nicely done!
  • 6 months ago kahless1980 Level 9
    Hello!  I am very impressed by your creations.  I see you love the classic models.  I myself am a very bad lego designer, so I would be glad, that you look at the model of the BMW M1 and in the future could be made from the 42056 .... of course as a pure idea / suggestion template.
    • 6 months ago Pleasedontspammebro Level 10 Designed this MOC DESIGNER
      Hi Kahless1980,
      Thanks for your kind words!
      I have a folder with cars that I love and want to build MOCs of and the M1 is definitely in there!
      It's a brilliant car and even has the right number of cylinders to match set 42056. Just don't hold yoiur breath, I can't see me releasing more than one MOC a year and the rest of this year is crazy for me with my work.
      Keep an eye on Rebrickable - you never know what will turn up!
  • 6 months, 2 weeks ago dtrin Level 5
    I bought these instructions as soon as I saw your model. I'm currently building this and I must say that your model is genius. The structure, the lines and the functionality is better than any Lego officially released technic model. The instructions are great and challenging - for more advanced builders. My only concern so far is the gear that connects to the engine to the gearbox tends to slip as there doesn't seem to be anything fastening the end where the gear is... about a centimeter of floating axel?(could be me not following the instructions correctly too). Thanks for sharing your outstanding work, much appreciated. The Stratos will be next! Have you had crack at the Chiron yet?
    • 6 months, 2 weeks ago Pleasedontspammebro Level 10 Designed this MOC DESIGNER
      Thanks for the feedback!

      About the connection between gearbox and engine.
      This is how it is meant to be - the float allows for the gearbox not being in alignment with the rest of the build. Since all of the cv joints and bevel gears in the set are used elsewhere I have used the float in the axle to allow a little flex and make the connection.
      The the only clutch gear in the set is used to deal with potential stresses in the connection between the steering and the driver's wheel so allowing for some low stress skipping in the drivetrain was also important.
      Make sure that your engine is assembled accurately and no too tight - if the engine can turn easily then you will have no skipping of the gear in question.

      Hope this helps!

      • 6 months, 2 weeks ago dtrin Level 5
        Thanks for the response.  I may have to revisit the crank shaft alignment again i think. That maybe the cause of my binding.
        • 6 months, 2 weeks ago Pleasedontspammebro Level 10 Designed this MOC DESIGNER
          How did you get on?
          The crankshaft is the most probable cause of binding, did you manage to get it all moving nicely?
          • 6 months, 2 weeks ago dtrin Level 5
            Yeah all good! I love everything about this model.
            Unfortunately I had applied a lot of the Porsche stickers on the round 2x2 flat plates I so had to settle for round 2x2 studded plates for the wing mirrors. I managed to put the speedo and tacho in the interior for the dash though, so all good! Have you considered a b-model for the technic  Chiron, because you'll be taking my money for what ever you come up with for that too.
            • 6 months, 2 weeks ago Pleasedontspammebro Level 10 Designed this MOC DESIGNER
              Would love to see photos of the dash. 
              I’m playing with the Chiron set digitally at the moment. Haven’t yet put down cash for the set but I do like the idea of never running out of cylinders. 
              Watch this space...
              • 6 months, 1 week ago dtrin Level 5
                Nothing special with the speedo, found some spare studded blue bolts and  put the dials directly in front of the steering wheel. No binnacle  or anything.
  • 6 months, 2 weeks ago Pleasedontspammebro Level 10 Designed this MOC DESIGNER
    For those of you that have already purchased the instructions, please refer to the change log in the description and download the revised files. Turns out that catching bugs before release never goes smoothly ;)
    All the changes are implementable after the build is finished and anyone downloading the instructions now will get the revised edition.
  • 6 months, 3 weeks ago Dutch260Z Level 6
    I fell in love with your build, thanks Google suggestions for bringing it to my attention. I've been looking for a Lego Z since I bought my real project Z a few years ago as I occasionally need something to (re)build that is not rusty and falling apart, just to stay motivated! Yours is the first that actually gets the roofline and window curve perfect! I've ordered a Gt3 just for this. Can't wait to get started! I'll be thinking real hard on a way to make the dashboard look more like the original though ;-)
    • 6 months, 3 weeks ago Pleasedontspammebro Level 10 Designed this MOC DESIGNER
      Thanks Mate!
      I agree about the dashboard but I couldn't find any options in the bricks that were left that didn't look clunky.
      And I TOTALY agree about the Z - sooo jealous that you have one.
      Have you seen the brilliant and unholy things that the guys at Mighty Car Mods have done with one?
      Check it out on YouTube, it even starts with their trip to Japan to source the car.

      When you figure out the dashboard be sure to post some photos here!
      • 6 months, 3 weeks ago Dutch260Z Level 6
        I have some ideas for the dash, I'll have to plunder some sets I have though. I've seen just about everything on YouTube and Insta that is related to Z's. MCM is indeed one of my favourite shows along with home built bij Jeff. There's a wealth of information to be found online for the starting and novice car restorer. Not sure you should be jealous by the way, I have years of of work ahead of me before I'll actually get to drive the Z.
  • 6 months, 3 weeks ago zonoskar Level 8
    I like everything on the model, except the grey rear panels. I assume there were no black ones left? The car was called "Datsun" in my country though.
