    Hi guys, I have a 8th gen civic si, and today I came to see that I was getting a constant blue tinted smoke coming out the exhaust when the car was idling. I know the car burns oil but I have never seen it like this. I did a bit of research and most people say it is because of a bad PCV valve. I...

    Hello all, I am from Barbados trying to complete my project. It is a JDM FD1 auto R18 that I am in the process of converting to Manual K20Z3 So far, we have swapped in the K20, did all the suspension work, brakes, axles, and now at the electrical side of things. I will create a complete build...

    Hi everyone, Feel free to just link me to a similar thread if this is a repeat if another question, but I have an 8th gen si that has 200k miles and I would like to boost it when I eventually rebuild/swap. I would prefer to keep the low torque of a k20 so would it be worth it to rebuild over a...

    How high can I up the limiter on a bone stock k20 with hondata and still rev safely (not blow anything), or can I up it all? What supporting mods would I need to safely rev to 8500 or 9k rpms? Thinking about getting a type s oil pump but if that won't be much help should i go with a type r...

    Hi, I have a 07 civic si with the k20z3. I disassembled the bumper to change the windshield washer tank and change my bulb to LED for the headlight and I was wondering if it was worth it to take apart the injector rail and clean the injector if my k20z3 have 338 600km (around 212 000miles) btw...

    Car is no start no crank. the starter I pulled from the k24 accord is working (verifie& tested by autozone) but wanting to make sure it would work. I have also seen this plug that goes into the starter has broken? Will it still work fine? Or would I need a new wiring harness?

    Hey, dont know alot about cars, wanted some insight. 3 months ago I bought an 8th gen civic si with around 220,000 km on it. Just noticing that the engine vibrates a bit? Is this normal? Any opinions are greatly appreciated. I have a video (not the best quality I apologize lol) which sorta...
  8. Civic Si
    I just set my K20Z3 rev limiter to 8800 RPMs with VTEC raised to about 6100 RPMs and she's making power all the way up to 8800 RPMs. I think it can make power well into the 9000s. But I'm at 8800, what I have modded is not much. Straight piped exhaust, aftermarket valve springs, aftermarket...

    Just bought my si at the start of the year and already the engine has locked up on me. I believe the previous owner most likely knew of some sort of problem and didn't tell me, but regardless I have a new engine coming in and it will be swapped the week of April 3rd. I wanted to come here first...

    * Video at the end of this post * Anyone have any idea what causes the car to click when accelerating from a dead stop? The clicking even sometimes happens when I accelerate going about 50 km/h (30 mph) in 4th gear but not as bad as going from a dead stop. When changing gears, the clutch pedal...

Every time the passenger side door is opened, the handle would have to be pushed in in order for the passenger...

    I pretty much bought a shell of an 09 Civic Si 2Dr. Was looking to purchase a k20z3 since its the same one that came with it, didn’t want to have to change a lot of parts.
