Honda NSX type 1
A reproduction of an iconic car from the 90’s : the honda NSX type 1 featured V6 fake engine with rear wheel drive, steering with steering wheel, double wishbone suspensions, pop-up headlight, opening doors, hood, trunk and rear glass roof, and adjustable seats.
The story of this project
I am a big fan of Honda (no really ?), but it is not a big deal, I am trying to cure myself.. by buying Honda car and motorcycle. I own a 89′ Transalp, and recently a Honda legend Ka8, but having a NSX is still not in my budget ! So I planned a long time ago to make one in lego. In beginning of 2017, a fan of lego and honda named Elvis, contacted me for questions about the Honda Ra300 I made in lego. Following some discussions about Lego and Honda, I discovered that he ownes the legendary Honda NSX. After that we met in order that I give him some parts to finish his Honda RA300 and it gives me the opportunity to see in real the NSX, take detailed pictures and drive it ! Then, I decided to make the NSX in lego.
I have started to use the 53mm wheel instead of big 68mm because of the scale and the result in quantity of parts. I think it is a good scale for manual car. Then I started with the chassis, trans-axle, and finished by the bodywork. The reproduction of the NSX in lego is equipped with full suspensions, as double wishbone inspired by the Groupe B Rally Car.
The trans-axle is a rear wheel drive, due to the scale it is always complicated to have wheel drive and double wishbone suspensions. On the Group B rally car I used soft ribbed hose to connected the wheel to the differential, because these parts are 2-stud wide, instead of the 3L U-join but it works only by friction, excluding motorization. But for the NSX, I figured out to find an other way. I use in fact a floating differential enables me to not use U-joint for the axle, only Cv-join connected to the wheel hub. For that I use a 4L old differential which drives couple of 16t gear, and then 24t/12t to drive the V6 engine. Of course at this scale this is not possible to have a gearbox, or with removing the detailed of the interior which I did not want.
The steering is classical made with rack and pinion on the front, with an axle for the hand of god (which is by the way removable) and an other with a gearing and 2 U-join to operate the steering wheel in the interior.
The pop-up headlight are operated by a lever in the dashboard. This lever drives a connectig rod which is also connected to a lever. And this lever command the displacement of the headlight by pushing the base, which causes the small rotation of them. It was a bit tricky to pass the whole connecting rod and system in it but it works fine and can be operated from the interior which was important for me.
The design was of course the most difficult part to do. It was also the most important ! Because the Honda in lego need to be realistic but also easy identifiable, that is why there are some interesting and important parts to reproduce, like the rear wings, the black roof, pop up headlight, shape of opening parts and so on. The only compromise that I did is for the doors, which do not respect the airflow intake shape.
I started the design by the rear parts with the bumper, exhaust and rear wing. I wanted to reproduce the gap between the bodywork and the wing and use simple configuration of panels, which I did. Then I do the opening trunk and started to build the front. I made the front bumper, originally with more parts and more bulky but I restarted it by using some black parts to give the front bumper enough stiffness but also aggressive look. After that I build the black roof with the opening glass roof and the important C-pillars which are oblique. Then I finally make the windscreen and the opening hood and pop-up headlight.
I have to restart many time to get the correct shape of this hood including the system for the headlight and have a correct opening shape, which was very difficult. You can see some holes without parts near the headlight, which is a compromise because of the room I have a steering wheels. You can see also on the video that I implement (at the end) a system to release the hood with a lever between the hood and windscreen.
Then I finished the design by the doors, which have been also complicated because of the airflow shape. I would like to reproduce the thickness and the curving shape of the doors, and also include the airflow shape, which was not possible at the end. Maybe with bigger scale. But at the end, the shape is a bit here and there are also the two big airflow intake just after the doors before the wheel arch.
I made the interior at the end, which was not complicated with the dashboard, central console, lever and parking lever. Then added two bucket seat thanks to many panel and made the adjustable position which is in fact a slidding connector on axle.
To conclude, I have tried many time to do the honda NSX in lego, but this time I started by the most difficult parts : the rear with the wings, and then build the other parts. Make the correct opening shape with the functions like pop-up headlight was complicated, that is why I have to do compromise (like the hole near the headlight, and the shape of the doors) but at the end, I am really happy with this car. On some views, the shape of the car is well done and respected, plus the distinctive parts like the wing, roof, and headlight make it easy identifiable. I could say that I find the front parts a bit bulky and more heavy in style that the rear, and some continuity problems of the panels near the doors (again for enabling the opening). But making lego scaling is always compromise to find the correct parts and assembly to fit, with good homogeneity and continuity, and respecting the functions ! I do my best for it and at final thing that the bodywork is rather successful.
Purchasing the creations or the instructions
You can purchase either the whole creation on the website mochub, or just the building instructions. Regarding the building instructions, you can download one version as a photo sequence for free or buying a other one which looks more Professional with rendering step by step instructions with bill of material at each step.
Want to buy this creation ? The Lego Honda NSX in Red or white have been indexed to mochub and are for sale at $539.95 for Red version or $439.95 for the white version. The whole package included the parts, and the Pro rendering PDF building instructions.
You can also buy if you want special NSX rim cover designed by Sevenstuds and 3D-printed from shapeways (9.11$/rim) :
I have not tested yet but I think it cover nicely the wheel. You can keep the original light bluish grey wheel or put it some black one. In any case the rim cover are not supplied with mochub package.
I have made two instructions as usual. A free one based on picture and a pro one, with bill of material, step by step, callout and step group with pro looking. Both include the bill of material :
As this car was at first a dream in lego (I wanted to do it for a while), and then a gift for Elvis, I decided at the begining to make the building instructions, by building with a comprehensive assembly and no rare parts (except some flex of course..). That is why, I have made the photo sequence instruction in correct order and then send to Kevin Williams who plans to make the pro-building instructions. So I can propose you the download of the photo-sequence as PDF (188 pages – 62mo) or buying the Pro-looking version made by Kevin Williams in two version : a red one and a white one.
Here is the complete bill of material in picture file for the Red one :
Here is the complete bill of material in picture file for the White one :
But you can also checked it on rebrickable :
You can buy the instructions with the following button for 10€ (red version or white version).
After your payment, you will be redirected to a page for downloading your instructions, and will receive also the link to download by email. Please check the spam box and be patient to receive it. If you have trouble to download your copy of the PDF after payment or open the document, do not make a paypal dispute, please contact me using the contact form. The link to download the instructions expires within 24h. Contact me if you have lost your instructions. Note that you can print it, but not copy or distribute. Thank you for supporting my work 🙂
Free Photo Sequence
Please note that the bill of material can be different for the free version, because the bill of material has been generated by the CAD model of the NSX of for sale instructions which is an improved version. The free version of the instructions refer to the first edition of the NSX, therefore watch carefully the parts you need before (not big change, some pins, conenctor, front hub wheel).
