2.0L CivicX 2.0L Tuning - BIG Gains Confirmed For The Second Time

Has anyone seen this?? The description says its for the 2.0. But there are no reviews or anything so im not sure about it.]

That manifold is for a different gen civic.

If you want to actually gain power, beyond a tune and a downpipe, you have to upgrade the front pipe.

The problem is that the stock front pipe tapers from 2.25” ID to 1.75” ID after the flex section, so you have to remove that restriction to gain any more power.

But since it’s not possible to buy one, you have to make one. I did this by cutting an Invidia 1.5T front pipe and welding it to the OE downpipe connection.





When combined with an aftermarket “catback” I noticed a substantial increase in torque throughout the rev range. Gain was about as noticeable as the RV6 downpipe.

Isn't this for the turbo model?

The engine doesnt adjust to the different fuel? The ECU isnt as smart as I thought... So the Si and Turbo cars can see a downgraded fuel, But the 2.0 Cant see an upgrade in fuel

That's not exactly how the ECU or fuel grade works. ECU is designed for the expected combustion of a specific grade of fuel. 89 actually explodes quite a bit more than higher grades, but not nearly as cleanly. Lower octane burns faster and harder (think of pine wood as low octane, and oak as high octane, though that's only part of the story). Piston rotation and compression timing is a lot tighter on higher octane. You can even roll compression ratios into the mix, but isn't as big of a factor until you're dealing with extreme high revs (8k+)or high compression (turbo). Tune adjusts the timing to account for the different octane, allowing it to be much more efficient at higher revs - which is why is sucks more gas in traffic at low rpms, it's having to try harder. Opposite at high rpms.

Well my Ktuner V1.2 came in and I flashed my ecu. It did lower my vtec engagement and I selected the improved throttle response. But I was wondering does anybody know what all this program is supposed to change. Like the speed limiter, adjusted rev hang are already included in this program?

I havent seen 2.0 software but I assume rev hang delete is in the "enables" tab. I dont have a 6MT either but it should be here.

Thanks guys I’ll check it out this Friday and see if I can find it. I’m also thinking about getting the acuity shift kit. I reading that it helps the shifting a lot. So I’m doing my research

I would suggest getting a data log tune from somewhere. One for 93 octane one for regular octane and of course back to stock for dealer purposes

I have been trying to find those 9th gen si rims you have but haven't had any luck

I got mine at roadreadywheels.com. They are actually replica rims. But rims are rims in my book, they are just cast chunks of aluminum. They are the same exact size, weight, and everything. They are very good quality. When I got mine they were $146 each. They have gone up a little since then but still cheaper than buying from Honda.

Thank you all for the info!!
I’m ready to start upgrading under the hood.

I wanted to post a picture of my rims when they came in. As you can see they look great.

Other rims that are nice are the accord sport rims. But they are 19”

Yeah the older accord sport wheels look really good too

Yeah I like how Honda actually puts good looking rims on their cars stock
