How to make honda civic ex faster

In 2016, Honda kicked off the Civic’s 10th generation by redesigning the car’s exterior, boosting its handling, and offering a turbocharged engine option.

The new Civic is great on its own, but sometimes you just want that extra performance boost, like one of these five tried-and-true performance modifications:

1. Engine Tuners and Programmers

Every new car has an engine control unit (ECU), which is a computer system that manages the engine’s performance. To boost performance, you can tweak your ECU's settings with tuning software. This software is usually referred to as a "tuner" or "programmer." By changing the fuel map that's built into the factory ECU, more engine power can be unlocked. Usually, the trade-off is that you'll need to buy premium gasoline (not a big deal).

The trouble with Honda is that there aren't a lot of companies offering tuners/programmers. Hondata has a couple of reflash options, which you can find here:

  • 2016-2017 Civic Turbo 1.5L Hondata FlashPro
  • 2017 Civic Si Hondata FlashPro

But these aren't so much tuners as they are reprogrammed ECUs. While they have some advantages, they're expensive compared to a regular old engine tuner/programmer. Until the aftermarket offers more options, Hondata is basically the only game in town.

Still, you can't argue with the benefits - depending on what tune you select, you can increase the 1.5L turbo engine torque output 30%. That's incredible...with a $600-$700 upgrade, you can make a regular 1.5 turbo Civic into a car that puts out more power than a new Civic Si.

2. Cold Air Intakes

Upgrading to a cold air intake setup is a quick, easy, and affordable way to give your Civic a little extra kick. While this modification doesn't add a ton of power (5-10 horsepower is about the limit of what you'll gain), there are some other benefits:

  • Improved throttle response
  • More engine noise at wide open throttle - your car will "sound faster" when you get on it
  • The modification is easy - all you need is 45 minutes and hand tools

Cold air intakes add power because they include high performance air filters that do a better job of moving air thru the engine. OEM air filters are made from paper, which is primarily chosen because it's so inexpensive.

Additionally, cold air intake kits pull air into your engine further away from the engine compartment. As your engine heats up, the air around the engine heats up too. If your engine is breathing in hot air, it's less efficient.

3. Cat-Back Exhaust Systems

Factory exhaust systems have two goals:

  1. Be quiet
  2. Be cheap

They're designed to be quiet and cheap because that's what a majority of new car buyers want...if your older neighbor buys a brand new Civic, they want a good price and an exhaust that they can't hear. But you? You're probably willing to spend a few dollars on a system that boosts performance, even if it's louder than stock.

If you invest in a tuned cat-back exhaust system that's designed specifically for your Civic, you'll enjoy improved horsepower and torque. That's because aftermarket systems use higher quality mufflers that aren't as restrictive as the lower cost OEM mufflers, as well as mandrel-bent tubing that flows better than than they typical crush bent tubing in OEM exhausts.

Of course, aftermarket exhausts are louder than OEM. If you don't mind the noise, an upgraded exhaust is an easy way to add another 5-10 horsepower to your Civic.

4. Suspension Lowering Kits

Lowering your Civic so that it's a couple of inches closer to the ground has a number of performance benefits:

  • A lower center of gravity that reduces body roll (or lean) while cornering
  • A lower center of gravity also improves cornering ability, as it allows the tires to grab harder (basically...you're increasing lateral force on the tires, which makes them grab more)
  • A lower ride height reduces drag, especially at higher speeds

However, before you go out and buy a lowering kit, it's important to understand that lowering your car can have a big impact on ride quality. If you install a new set of adjustable coilovers on all four corners, you'll be able to tune the suspension to reach the right combination of cornering ability and ride quality.

But if you go with the least expensive set of lowering springs you can find, swap those out with the OEM srpings, and then hit the road, you're going to feel every bump. So, if you're concerned about ride quality, avoid the cheap stuff.

5. Forged Alloy Wheels

Last but certainly not least, we have upgraded alloy wheels. While some wheels are designed only for looks, a good set of forged alloy wheels will improve performance in a couple of ways:

  1. Forged alloy wheels are a few pounds lighter than the standard cast wheels, which means it takes less engine torque to get them rolling (and less force to stop them). A slight decrease in wheel mass can lead to measurable improvements in 0-60 times, as well as reduced braking distance.
  2. Forged alloy wheels have less unsprung weight, which means your shocks and suspension system will work better in terms of responding to the road. You'll notice the car is a bit "quicker" in the corners if you upgrade to a forged wheel.

Forged wheels are also stronger than cast wheels, which is nice if you plan to race your Civic on the track.

Summing Up

The first Honda Civic slogan was, “It’ll get you where you’re going.” With all of the above performance-boosting mods, your Civic will be shockingly quick compared to a bone stock Civic...it won't just 'get you where you're going.'

  • A Hondata reflash is good for 20-40 horsepower, and even more torque
  • Cold air intakes and tuned cat back exhausts are good for 5-10 horsepower each
  • A lowering kit will improve cornering speeds, as will forged alloy wheels

While you won't notice all these upgrades day to day, you'll definitely enjoy the increased performance while taking off from a stoplight, or passing on the highway. And if you track your car? Forget about it.

As always, drive safe.

How fast is a Honda Civic EX?

Utilizing the quick shifting to surprise drivers, the 2021 Honda Civic has a top speed of 137 mph. Quick on the draw, this speed is reliant on driver ability and displays the engine ability of the 2021 Civic.

Can you turbo a Civic LX?

A turbo engine is standard on all models except for the LX.

Why are tuned Civics so fast?

A popular reason why Civics are popular is because of its VTEC engine. VTEC is a valve timing tech of Honda that gives better combustion/fuel atomization that improves total airflow providing higher top-end power.
