As the title suggests, this review covers a selection of 1:18 scale motors from MotorHelix. While I may not be an expert in Japanese cars or their rich culture, I’ll do my best to provide an honest perspective on these detailed miniatures. Hopefully, the accompanying photos will speak volumes where my words might fall short.
MotorHelix is a relatively new player in the scale model market, but the team has already impressed with standout pieces like the Alfa Romeo Giulia GTA and the iconic Honda S2000. These motors, sent to us alongside the previously reviewed models, are no exception to their dedication to quality. The lineup includes the following engines: Nissan VR38DETT, Nissan RB26DETT, Mitsubishi 4G63T, Honda K Series and Honda K20C.
Each motor is securely mounted on a sleek plastic base, featuring a metal badge that identifies the engine model. The packaging design mirrors what you might see with 1:43 scale car models: compact, functional, and protective. This setup not only ensures safety during shipping but also gives collectors a display-ready piece straight out of the box.
MotorHelix has poured an impressive amount of effort into recreating these engines. Made primarily of ABS or PVC, some models also feature photo-etched components for added realism. The layers of detail are remarkable, extending beyond the engine block to include elements like transmissions and intercoolers.
A standout feature of the Honda K20C and Mitsubishi 4G63T models is their removable parts. The K20C comes with a detachable engine cover, while the 4G63T includes a removable valve cover. These pieces are secured using either friction or tiny magnets, adding an interactive element that sets them apart from static replicas.
The use of textures and colours is where MotorHelix truly shines. Exhaust systems, piping, and other intricate details are carefully painted and textured, creating an authentic look. The contrast between metallic finishes and rubberized elements gives these models a level of depth that appeals to enthusiasts and casual collectors alike.
That said, some black components lack the fine-tuned realism seen in other parts of the models. This is noticeable only upon close inspection, and it doesn’t detract significantly from the overall quality.
When asked if the same level of detail is applied to the engines in their car models, MotorHelix confirmed that they strive for consistency. However, the variability in engine series—B, K, F, and so on—poses some challenges.
Excitingly, the brand has plans to expand its lineup beyond Japanese engines. Additionally, these models are not limited editions, so there’s no need to rush. Collectors can take their time building their collections without the fear of missing out.
MotorHelix has carved out a unique niche in the diecast world by offering standalone engine replicas at an accessible price point (MSRP USD 23.95). These miniatures give collectors an opportunity to appreciate automotive engineering on a smaller, more affordable scale.
While not flawless, the level of craftsmanship and attention to detail is impressive, especially for a relatively new brand. Whether you’re a diecast enthusiast or simply intrigued by automotive design, these scale motors are worth considering. Feel free to reach out with any questions, and we’ll do our best to get answers from MotorHelix. Enjoy the pics!
Thanks for the review. Yet, with so little resonance in the comments I recommend that the engines should be sold separately, not as an add-on with the model cars, so that the model cars can be cheaper with the engines as a separate option.
We would agree with the above too. Lower cost on the model cars, remove the filler and target a more aggressive price. This would be disruptive!
Agreed. I have so many of them now, multiple of each.
Probably in collecting Alfa Romeo colours? If so, you will get more Alfa engines, once the GTAm is released. And yet more if Motorhelix add the Quadrofoglio, which I hope they will, and in a POLIZIA (with lightbar) and CARABINIERI (with beacons and message box) version too.

I do have 2 of the Alfas but I actually don’t display the engines. They don’t look as good as the others imo, too modern. But I have one S2000, three R34 GT-Rs and three EK Civics. So that’s 9 engines, plus one from Polar Master. I also bought a couple of extras to use in future builds, so yeah. Lots of engines sitting around lol
