Up to this point, we've put on an aFe Turboback Exhaust, AEM Intake, and created a custom calibration through our KTuner device. The car is running great and has significantly improved in both power and torque, over stock. We're currently using 91 octane pump gas only. However, we've seen evidence that a better intercooler would help us out a lot. So the Mishimoto core was called to duty.

We've been seeing that many of the 1.5T 10th gen Civics out there experienced the stock clutch slipping and not being able to hold much more power than stock. We were curious when our 10th gen Civic clutch would give out and it came sooner than we hoped. After a turboback exhaust, intake, and some tuning, 4th gear started to spin the clutch and it just couldn't handle the power. In order to continue forward with our project and keep adding more power and torque, the only option we had was putting a new clutch in.

It was actually weird how well the 10th Gen Civic Si coupe handled when I test drove one before we bought it. I guess I just wasn't expecting it to feel that good. But like any factory car, it's not perfect. There is almost always aftermarket equipment that you can bolt-on and setup to make it perform even better. Whiteline provides us a much nicer set of suspension accessories to get that done on Project FC3, our 10th gen Civic Si. We went ahead and started with the Whiteline rear sway bar, rear end links, and front end links.

Our 10th Gen Honda Civic Si has been a riot so far and with the addition of a new intake system from AEM, we're excited to keep squeezing out every ounce of power that we can from the stock turbo. A turbo requires a lot of flow to work efficiently and, in theory, removing the factory paper filter and airbox should give us noticeable increases in power and torque. How much is something we had to find out for ourselves on our dyno.

With our newfound power courtesy of the aFe Power exhaust system, we were very excited to finish the exhaust part of the project with the downpipe and the midpipe. We knew this would really let the turbo breathe much more than the stock system and give us a great sound, as well. All of our wishes came true.
