1. I Put a Real V8 Engine in My RC Crawler—Because Why Not
One of the wildest CISON V8 builds we’ve come across is from a guy who decided that his RC rock crawler wasn’t complete until it had a real, working V8 engine crammed inside. Not just for looks—this thing actually runs on fuel, shifts gears, and shakes the whole chassis when it starts. He ditched the stock electric motor and went full mechanical: CISON V8, custom gearbox, handmade exhaust, throttle control via servo, the whole deal. It wasn’t easy. The engine was way too heavy for the original frame, so he had to rebuild the mount from scratch. The balance was off, so the chassis got reinforced with aluminum plates. And hooking up the drivetrain? That took days of trial and error. But once it fired up for the first time—loud, raw, and real—you could tell it was worth it. “It’s kind of ridiculous,” he said, laughing, “but also kind of awesome.” This build isn’t about performance stats or efficiency. It’s about making something absurdly mechanical, just because you can. And in the end, that engine didn’t just power the wheels—it brought the whole project to life.
A Quick Heads-Up from STIRLINGKIT:
If you’re serious about your builds and love adding that next-level realism, the new Cison transmission gearbox is definitely worth checking out. It makes your V8 engine feel more authentic by letting you actually shift gears — just like the real thing.
Whether you’re a hardcore modeler who loves fine-tuning every detail, an RC driver looking for better control, or just someone who wants their engine to perform like the real deal, this gearbox takes your build to a whole new level.
We know you care about quality and the small stuff that makes a big difference. Adding this gearbox turns your Cison V8 into a true mechanical gem — more fun, more realistic, and totally satisfying. Give it a shot and see how much more you can get out of your model!
2. When an RC Truck Gets a Real Engine: The CISON V8 Swap
Another standout project comes from a builder who mounted the CISON V8 engine into a 1/10-scale RC pickup truck—not just for show, but as a fully functional, fuel-powered upgrade. The goal was to keep the realistic proportions of a classic pickup while integrating a real combustion engine under the hood. This meant completely rethinking the truck’s internal layout. The builder custom-fabricated an engine bay, reinforced the front chassis to handle the extra weight, and mounted the gearbox to transmit power to the rear wheels. One tricky part was heat management—ventilation had to be added to prevent the body shell from warping under prolonged use. Another challenge was throttle response and idle stability; it took hours of tuning and servo calibration to get a smooth, controllable feel. The result? A pickup that doesn't just drive—it rumbles. It starts with a flick of a switch, breathes through its own exhaust system, and idles with the subtle shake of a real engine. It may still look like a toy truck on the outside, but under the hood, it's pure mechanical reality.
3. Tiny Car, Big Power: When Your CISON V8 Gets Too Excited
John is not only a passionate RC modder—he’s also a cat lover with a soft spot for high-speed builds. His latest project features a heavily customized CISON V8 engine mounted on an open RC chassis, complete with a tiny NOS system at the rear. While warming up the engine for some launch tests, John got a bit too excited. “Kids, this is why you always keep the body on,” he joked. At around 20 mph, a quick throttle pull sent the car into a full spinout and a dramatic cartwheel. The aftermath? A damaged air cleaner (already repaired), a popped camber bolt, and a locked clutch. But setbacks didn’t slow him down—he used the opportunity to upgrade from a 2.5:1 to a 3.2:1 gear ratio, aiming for better top-end performance and more controlled launches. With the clutch fixed and the new gearing in place, John’s ready for the next round of tests—weather permitting. His build is raw, loud, and unapologetically overpowered, just the way he likes it.
4. The Builder Who Never Stops: Jamie’s 4-Build RC Engine Saga
Jamie is the kind of builder who never stops experimenting. With a deep passion for mechanical realism and a hands-on approach, he’s already tackled three standout projects—each one more ambitious than the last. It all started with a rugged RC4WD Beast 2 6x6, which he converted from electric to gasoline using a Toyan FS-L400BGC engine. Then came a beautifully restored Model A pickup powered by a CISON OHV V8, followed by a 1/5-scale Morgan 3-Wheeler featuring the CISON V2 FG-VT157 engine. But he’s not done yet. His fourth project, still in progress, is an old-school trike powered by the Toyan V8—his most complex and visually striking build to date.
More than just a builder, Jamie has become a source of inspiration for many in the community. His relentless curiosity, willingness to experiment, and generous sharing of progress and setbacks alike have motivated others to pick up their tools and dive into engine model building. Whether you're into vintage pickup trucks or high-revving trikes, there's something contagious about Jamie’s passion. And with the Toyan V8 project still in the works, we’re all eagerly watching—because when Jamie builds, the whole community gets excited.
5. Miniature Muscle: Retro Air Filter Meets CISON V8
Sometimes, the magic is in the details. This builder leaned into the CISON V8’s factory orange paint—already reminiscent of classic Chevy small-block engines—and gave it the finishing touches it needed to fully channel that American muscle vibe. By adding a retro-style air filter on top, modifying the intake mount, and polishing up the valve covers, he transformed the engine from a raw mechanical model into a scale tribute to one of the most iconic V8s in automotive history. The result? A mini engine that not only runs and rumbles like the real thing, but looks like it came straight out of a '70s Chevy engine bay. It's not about speed—it's about honoring the golden age of combustion, in miniature.
6. Old Wood, New Roar: CISON V8 Powers Up a Classic Boat
Unlike most builders who work on cars or trucks, this gentleman in his fifties decided to try something different — installing a CISON V8 engine on his wooden boat. Steve has spent a lot of time working with wood and enjoys the simplicity and feel of a classic boat. Adding the V8 engine was his way to bring some real mechanical power and sound to it.
He chose a wooden boat because he likes the traditional craftsmanship and the slower pace of boating. It’s not about speed, but about enjoying the process and the experience.
Fitting a metal engine into a wooden hull wasn’t easy. He had to figure out how to secure the engine without damaging the wood, deal with vibrations, and set up proper cooling. It took many hours of trial and error.
Now, the boat runs smoothly and has that authentic V8 rumble. For him, it’s less about racing and more about mixing old-school building with real engine power — a project done with patience and passion.
7. The Ultimate Tank Build: CISON V8 Inside a Scale Model Armor
This builder W took on a serious challenge by fitting the CISON V8 engine into a fully handmade scale tank. Unlike cars or boats, tanks have cramped interiors designed for armored components, not engines of this size. To make it work, he had to completely redesign the engine bay and fabricate custom mounts that could handle the tank’s weight and recoil-like vibrations when moving over rough terrain.
Cooling was especially tricky since tanks rely on enclosed spaces and limited airflow, so he engineered a compact, efficient cooling system that fits neatly without compromising the tank’s authentic look. Another major hurdle was integrating the engine with the tank’s original gearbox simulation, requiring precise adjustments to keep realistic movement while avoiding mechanical strain.
Despite all the complexity, the result is impressive: a powerful V8 engine roar fills the model, paired with smooth, controlled movement over obstacles — a true testament to his skill and dedication in merging heavy-duty mechanics with detailed scale modeling.
8. Q90’s Custom 3D-Printed Air Intake Scoop: Elevate Your Cison V8 Build
Building on the creativity of Cison V8 enthusiasts, Q90 introduced a special upgrade: a precisely designed 3D-printed air intake scoop. This addition enhances the model’s authentic appearance by replicating the classic V8 air intake, while also helping to simulate improved airflow for better cooling and smoother running. Offered as an STL file, it allows builders to customize the material and personalize their engine with both style and subtle functional benefits.
9. He Actually Rode It: A Mini Motorcycle Powered by the Cison V8 Engine
When we first approached Let’s Learn Something (1.11M YouTube subscribers) about trying the Cison V8 in a project, we thought he might build a static model. Maybe something to look at, maybe RC.
We were wrong. Months later, he surprised us — not with a display, but with a fully rideable, hand-built mini motorcycle.
From designing the clutch bell and building a planetary gearbox, to welding the chassis and assembling the wiring — every part was meticulously crafted in his workshop. The proportions? Spot on. The engineering? Seriously impressive. The fact that he could actually sit on it and ride? Absolutely mind-blowing.
As one commenter put it:
“I thought he was just making an RC bike — but he rode it himself. That’s hilarious and awesome.”
This project proves what the Cison V8 engine is capable of when it leaves the display shelf and gets bolted into a real machine. Small in size, big in heart — and yes, loud enough to turn heads.
