Can we make our Suzuki Cappuccino faster than a Mazda MX-5 _ Yuki Ep.2

**MOT Failure and Road Legal Makeover**

The car's MOT test was a disappointment, with the inspector citing several issues with the exhaust system. However, upon closer inspection, it became clear that the problems were not as severe as initially thought. The examiner had noted that the rear submountings were close to the flaky areas, but further investigation revealed that they were actually quite solid. With a bit of TLC and some clever repair work, this car was ready for its road legal makeover.

**The Exhaust System Makeover**

The exhaust system was one of the first components to be tackled. A new exhaust pipe was fitted, complete with a cool coating and a HKS finish. The old exhaust was carefully removed, and the new one was fitted, taking care not to damage any surrounding components. Next, the air filter was replaced, along with a new spark plug, which was surprisingly small in comparison to the rest of the car. A special HKS filter was installed, ensuring that the engine would breathe easily.

**The ECU Upgrade**

The next major upgrade was the installation of a new ECU (Engine Control Unit). The old ECU was removed and replaced with a new K-Sport unit, which promised to be "Plug and Play". This meant that minimal adjustments were required to get the car running smoothly. After some tweaking, the car was ready for a test drive, and the results were impressive. The engine sounded more purposeful, and the turbo noise was noticeably louder.

**Dry Ice Blasting**

Meanwhile, a new toy had arrived at the workshop - a dry ice blasting machine. This machine uses liquid nitrogen to blast away old sealants, rust, and grime from surfaces. The owner of the car, Steve, wanted to test it out on his NSX, which had been acquired recently. Half of the car was already done, but there was still plenty of work to be done. With the dry ice blasting machine, the process was quick and efficient, leaving the surface smooth and clean.

**The New K-Sport ECU Results**

After installing the new ECU, Yuki decided to give it a test drive. The results were remarkable - the car sounded different from the inside and out, with a noticeable boost in power. The ignition seemed to have improved, and the turbo noise was more pronounced than before. While not quite 100 horsepower, the numbers promised by this ECU upgrade looked promising. With any luck, Yuki would soon be able to push his NSX to new heights on the dyno.

**The Future of the Project Car**

As we left the workshop, it was clear that this project car had undergone a significant transformation. Half of the car was now done, and with the dry ice blasting machine in play, the rest should follow soon. The ECU upgrade had been a major success, and the sound of the engine was music to our ears. Coilovers, brake kits, wheels, and tires were on the horizon, along with more upgrades to push this car to its limits. With Drivetrack, we'll keep you updated on Yuki's progress and share every twist and turn along the way.
