Toyan Engine Modular Upgrade: Plug-and-Play Wiring + New Gasoline V8/Twin-Cylinder Engines
Have complicated wiring diagrams and fiddly assembly ever put you off building a Toyan model engine? Starting this September, Toyan is rolling out a complete modular engine upgrade — a new three-module system, a universal base, customizable cylinder head colors, and two long-awaited gasoline-powered engines. Here's everything you need to know before launch.
- Effortless installation: the new three-module design connects with just 3 main wiring harnesses — no more wiring headaches.
- Universal fit: one base now supports the Inline-4, B4, V8, and methanol V8 engines.
- Beginner-friendly: the manual has been upgraded with 3D diagrams and installation videos, so even first-timers can build with confidence.
- Two new releases: a gasoline V8 and a gasoline twin-cylinder engine — both previously methanol-only — launch in mid-September.
Lowering the Barrier to Entry
Building a model engine has traditionally meant deciphering complex wiring diagrams, wrangling loose electronic components, and troubleshooting endless connection issues. We've heard from countless builders that wiring is the single biggest source of frustration — miswired connections, loose plugs causing failed starts, and hours lost tracking down the problem. It's also the main reason many newcomers hesitate to get started.
To solve this, Toyan has completely redesigned the wiring system. The new 3-wire plug-in connectors dramatically simplify the process, delivering true plug-and-play installation — so you can spend less time troubleshooting and more time enjoying the build and the drive.
The redesigned 3-wire plug-in wiring kit
Core Upgrade #1: A Three-Module Design for True Plug-and-Play
New releases are now split into three core components, each of which can be purchased individually or bundled together:
| Module | What's Included |
|---|---|
| Engine Block | The core power unit |
| Starter Kit | All the essential electronics and a fuel tank, so you can get running right out of the box (note: due to shipping regulations, batteries and fuel are not included and must be sourced separately) |
| Base | The new universal base, compatible with four engine types (see below) |
Foolproof, Stress-Free Assembly
- Simplified wiring: the entire engine now runs on just 3 main wiring harnesses.
- Plug-in connectors: both the main circuit and the switch use 3-wire plug-in connections.
- Minimal effort: just tighten the mechanical parts and connect the harnesses — no special skills required.
💡 Tip: We recommend buying the full 1:1 set (engine + starter kit + base) for the smoothest experience and fewest installation issues — but each module is also available separately for builders looking to upgrade individual parts.
Beginner Friendly: Upgraded Manual with 3D Diagrams and Video Guides
Worried you don't have enough experience to get started? This upgrade goes beyond hardware — Toyan has also significantly expanded the instruction manual:
- 3D diagrams: every key installation step now includes an exploded 3D view, so you're never left guessing which part goes where.
- Video tutorials: an official step-by-step installation video is coming, so you can follow along in real time.
- Truly beginner friendly: combined with the simplified 3-wire hardware, the upgraded manual means even first-time builders can complete assembly on their own.
Core Upgrade #2: A Universal Base for Four Classic Engine Types
The redesigned base offers exceptional compatibility, fitting all four of the following engines:
| Engine Type | Compatibility |
|---|---|
| Inline-4 | ✅ Fully Compatible |
| B4 | ✅ Fully Compatible |
| V8 | ✅ Fully Compatible |
| Methanol V8 | ✅ Fully Compatible |
Each base features a clear model ID label on the underside, making it easy for collectors running multiple engine types to keep everything organized — no more mixing up parts.
Design & Customization: Classic Red & Black, Plus Custom Cylinder Heads
Based on extensive customer feedback, the red and black colorway — a look that captures Toyan's signature mechanical aesthetic — is now the primary recommended finish.
Want something truly one-of-a-kind? Custom cylinder head colors, including blue, are also available:
- Lead time: custom heads go through an anodizing process, so please allow 2–3 weeks and order ahead of time.
- Bulk orders can ship together with the full engine set — no separate shipment required.
Optional upgraded cylinder head colors, including the signature red-and-black finish and custom blue
New Release: Two All-New Gasoline Engines Launching in September
The most anticipated part of this upgrade is the arrival of two brand-new gasoline-powered engines — both of which were previously available only as methanol versions:
| New Model | Details |
|---|---|
| Gasoline V8 | Previously a methanol engine, now upgraded to gasoline power. Expected mid-September. |
| Gasoline Twin-Cylinder (SQ) | Previously a methanol engine, now upgraded to gasoline power. Expected mid-September. |
Meanwhile, the classic OT methanol lineup will continue with its existing sales strategy, so current owners don't need to worry about discontinuation or supply gaps.
It's also worth noting that new production batches will carry the refreshed Toyan logo — including on components like the speed limiter module — marking a full brand refresh.

FAQ
When will the new gasoline V8 and gasoline twin-cylinder (SQ) engines launch?
Both engines were previously methanol-only and are now being upgraded to gasoline power. They're expected to launch in mid-September.
Can a first-timer with no engine experience handle the installation?
Yes. Beyond the simplified 3-wire plug-in wiring, the manual now includes 3D diagrams and video tutorials, making it easy for beginners to complete assembly on their own.
Can I buy the starter kit or base separately?
Yes. We recommend buying the full 1:1 set (engine + starter kit + base) for the best experience and fewest installation issues, but each module is also available for individual purchase.
Which engine types does the new universal base support?
The redesigned base is fully compatible with the Inline-4, B4, V8, and methanol V8 engines.
How long does a custom cylinder head take to ship?
Custom heads go through an anodizing process with a lead time of about 2–3 weeks, so we recommend ordering ahead. Bulk orders can ship together with the full engine set.
Final Thoughts: An Upgrade Worth the Wait
From effortless 3-wire plug-in installation, to a fully illustrated beginner-friendly manual, to a single base that fits four engine types, to two brand-new gasoline engines — this Toyan modular engine upgrade covers everything from first-time builders to seasoned collectors.
