We’re excited to announce that the CISON LS-52 is officially here, and pre-orders are open right now. If you’ve ever looked at the engine bay of a purpose-built race car — aluminum block, a row of individual throttle bodies lined up across the top, stainless headers coming out each side — the LS-52 is that engine, scaled down to 1:5. It’s a fully functioning miniature V8 gasoline engine. Four-stroke, water-cooled, real ignition and combustion. It actually runs.
Why the LS-52 is a must-have
This isn’t a refresh of something we’ve done before. The LS-52 was designed from the ground up, and it brings six things to the table that no CISON production engine has had until now.
1. Drilled crankshaft oil passages
The LS-52 has oil passages bored directly through the crankshaft, so pressurized oil reaches the connecting rod bearings the same way it does in a full-size car engine. Most model engines rely on splash lubrication because the machining is too complex — this is a first for any CISON production engine. Those small holes in the crank aren’t cosmetic. They’re doing real work every time the engine runs.
2. MCU digital ignition
Distributor ignition runs on a fixed timing curve. It advances mechanically as you open the throttle, and that’s about all it can do. The LS-52 runs MCU digital ignition — a microcontroller calculates the optimal firing point for every combustion event in real time. Cleaner burn across the full rev range, better stability at high rpm. With 52cc of displacement and a 12,500rpm ceiling, the difference at the top end is something you can hear.
3. Top-mounted intake manifold
That black plenum sitting across the top of the engine isn't just a design choice — it's a faithful recreation of the original LS engine's factory intake manifold, one of the most recognizable features of the real thing. Any LS enthusiast will do a double-take the moment they see it. It's the kind of detail that tells you this engine was built by people who actually care about getting it right.
4. Built for vehicle integration
The flywheel already has mounting points for a centrifugal clutch and 6-speed automatic gearbox. Drop it into an RC build and the drivetrain bolts straight up — no custom fab. The water pump is integrated into the block with no external hoses, so the bay stays clean.
5. 3D-printed stainless steel exhaust manifold
Casting can’t produce the internal flow geometry that 3D printing can. The LS-52’s headers are printed stainless with optimized internal passages — better exhaust scavenging, heat resistance, and a finish that looks as good as it works.
6. Replaceable connecting rod bearing inserts
When the rod bearings wear — and they will eventually — you swap the insert, not the whole rod. Keeps long-term maintenance costs down. It’s the kind of thing that matters once you’ve been running an engine for a few years.

Build the V8 Yourself
The LS-52 arrives not as a finished engine, but as a box of precision-machined parts waiting to become one. Piece by piece, the structure of a real V8 takes shape on your workbench — the crankshaft settles into the block, eight pistons line up inside the cylinders, and the valvetrain begins to move as the engine turns. At first it’s just parts. Then it becomes a mechanism. And eventually, a real working engine. The moment you rotate the crankshaft and watch all eight pistons move together, you realize something: you didn’t just buy an engine — you built it. And when it fires up for the first time, that sound is the reward for every bolt you tightened.
