The ultimate power upgrade to your smart. The smart Turbo Upgrade Kit.
The smart 451 is a uniquely small and extremely power deprived vehicle that is typically thought of as a commuter car. Its small 1 Liter, 3 Cylinder engine is perfect for putting around town, to your job or even for long trips due to its compact size and very good gas mileage.
However, we felt that this particular car could use a huge boost in performance. Our goal was to provide a reliable upgrade backed by an experienced company that knows how to design a proper Turbo system and most importantly one that will stand behind their products.
Well, the task was accomplished and the Turbo Upgrade Kit is in production and available.
What is this upgrade all about?
Turbocharged with a high quality Garrett GT20 turbocharger! Garrett has a vast experience turbocharging a wide variety of high-end cars and due to this they have been able to come up with the perfect, eco friendly turbocharger system. This Turbo System allows the use of the factory catalytic convertor and still realize power increases of 90%!
To keep emissions down and still get the performance is really an incredible feat. We know how difficult it is to make power and still have a clean running car. We also know how important this is to the planet and all man kind!
Now you can experience a whopping 90% increase in power of your smart car!
This literally turns this car from one of the slowest thing on the road to a car that will shove you into your seat when the pedal hits the metal. Performance has increased so drastically, it will astound you.
When we first drove the pre production version we made a decision to become a distributor and even install this same kit in our own smart. After thousands of trouble free miles we still cannot believe how big of a transformation it is.
The quality of the system is top notch!
All of the hot side portion of the turbo system is made out of 304 grade stainless steel.
Every part is TIG welded on their special fixtures to ensure a perfect fit and finish.
All of the cold side components are made out of 6061 aluminum and TIG welded.
This system uses a real muffler which gives the smart an incredible sound, but makes very little noise. The sound inside the cabin is nice. You can easily carry on a conversation with a fellow passenger.
The tuning on this system is accomplished with a piggy back computer which controls fuel and ignition timing.
The smart ECU is made by Bosch is extremely sophisticated.This ECU's O2 sensor is constantly making adjustments to the air/fuel mixture to keep it as close to Stoichemetric (14.7 to 1) as possible. This is great for gas mileage but this is dangerous for boosted applications.
Thanks to the proprietary engine management system, a safe and reliable way to tune the car was found while still retaining all functionality of the stock ecu. The nicest part of this turbo system is you can go back to stock very easily if you ever had to. Just remove everything and that is it. Bone stock again....but what fun is that?
The Stage 2 smart 451 turbocharger system bumps up the power to an incredible 115 Horsepower at the wheels. The stage 2 system comes with an intercooler and boost is increased to 8 psi.
The intercooler is installed in the engine bay. It functions very well, thanks to an electric fan underneath it.Each turbo system comes with everything you need for a complete installation. Typical installation time is about 6-8 hours.
