Install a Turbo Timer: The Cool and Practical Upgrade
Want your engine to shut off by itself after you leave the car? Then it’s time to install a turbo timer. While it’s mainly designed for turbocharged engines, many enthusiasts add it to naturally aspirated (NA) engines just for the cool factor. Whether you’re doing it for style or function, this mod gives your ride a clean, pro finish.
What Is a Turbo Timer?
A turbo timer is a small electronic device that keeps your engine running for a preset time after you turn off the ignition. This allows the engine and turbo to cool down slowly, preventing sudden oil shutdowns and heat damage. It’s especially important after high-speed driving or aggressive runs where the turbo gets hot.
But here’s the twist: even if your car doesn’t have a turbo, the feature still looks slick. Imagine walking away and your car shuts off a few seconds later—it’s like a movie scene!
Why Should You Install a Turbo Timer?
Turbocharged engines heat up fast. If you shut off the engine right after hard driving, the oil can cook inside the turbo, causing carbon buildup and long-term damage. A turbo timer avoids this by letting the oil circulate longer, cooling the turbo properly.
For NA engines, it won’t save your turbo (because there isn’t one), but it still looks impressive and can help reduce engine wear if you’ve been driving hard.
Key Features of a Turbo Timer
- Automatic countdown shutdown
- Preset or manual timer control
- Prevent turbo heat soak

- Stylish touch to your car’s interior
How to Install a Turbo Timer (Basic Overview)

You’ll need basic tools and wiring knowledge. Here’s a quick look at how it’s typically wired using a relay:
- Signal wire (from ignition or a device like Apexi RSM) = Pin 86
- Ground (to car body) = Pin 85
- Positive battery connection = Pin 30
- Output to engine control or accessory = Pin 87
Make sure to check your vehicle’s wiring diagram and match your turbo timer wires to the correct ignition and accessory wires.
Pro Tip: Use proper connectors and fuses. A clean, secure install avoids shorts and system errors.
