Project FC3 Gets a Little Stiffer

Project FC3 Gets a Little Stiffer

By: JP Alonso / November 13th, 2019

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.

Project FC3 Gets a New INTAKE SYSTEM | Great Results, Dyno Proven!

By: JP Alonso / October 29th, 2019

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.

Project FC3 - Completing the Turboback Exhaust Setup On Our 10th Gen Civic Si

By: JP Alonso / October 22nd, 2019

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.

This has got to be one of the best mods for the money, if not THE best. Rear motor mount upgrades are not uncommon on front wheel drive cars. But for the price and effectiveness of a product like this, it is literally a NO BRAINER. Did I mention it takes about 15-20 minutes to install?

Project FC3 Gets a 3 Inch Exhaust - DYNO RESULTS!

Project FC3 Gets a 3 Inch Exhaust - DYNO RESULTS!

By: JP Alonso / October 8th, 2019

With Project FC3 fully under way with new suspension and custom ECU tuning, we wanted to start the bolt-ons with an exhaust system. After tuning, the exhaust is the second piece of the power puzzle we’re putting together. I’ve seen a lot of people talk about how exhaust isn’t that important or that it doesn’t gain very much power. I often don’t get a chance to prove this isn’t the case but this is one of those times.

Tuning Project FC3 - No Parts, HUGE Gains

Tuning Project FC3 - No Parts, HUGE Gains

By: JP Alonso / October 4th, 2019

Before we got started on installing any hard parts with Project FC3, our 10th Gen Honda Civic Si coupe, we wanted to see what this thing was capable of right out of the box with just some good ol’ fashioned fuel injection manipulation aka ECU tuning. By way of our KTuner device and custom tuning software which applies changes directly to the factory ECU, we were able to mess with the turbo boost pressure, ignition timing, and fueling to create more power and torque, all with just a computer and a dyno.
