  1. Si Installing ACT Clutch and Flywheel

    So I finally decided to bite the bullet and drop the tranny turned in to a two day job and day one was harder than I expected. Thankfully I have access to a lift and a full complement of pneumatic tools, jacks and stands. Not recommended if your thinking of going DIY. It is a serious undertaking...
  2. Si Finally got my Catback but what a hassle

    So in mid August I ordered a Borla S Type Cat Back exhaust system from Hoonagians Carcain. I bought` it for one because its Borla and they make quality stuff and two it was like 780 bucks on sale. It confirmed fitment for 2020 Civic Si Coupe but it did not give me a part number that I could...
  3. I just fell in love with my car

    Coming back from a little road trip. Mustang and Merc CLK wanna play and for 50 Miles we dipped through traffic and at no time did I exceed 110 MPH in the end my Civic took down a Stang and some German engineering. Maybe some luck involved but no overheating, that pherables tune had my boost...
  4. 1.5T How much of a difference does a performance Intercooler make V. Stock

    Thinking about what my next upgrade will be. I have cold air intake, I ordered a Cat Back, I have a sport clutch kit and single mass flywheel. I put in the acuity sifter bushings. Thinking about it the next logical step to get performance gains would be an intercooler. I dont have a tone of...
  5. Does Modding your car raise or lower the value?

    I'm not talking cheap carbon fiber accents for the interior trim I am talking quality performance mods. Cold Air Intake, Single Mass flywheel, sport clutch, short shiftier, big brake kit, Cat Back exhaust. I was thinking today I bought (partially financed) my car, a 2020 Civic Si, and...

    Running Pherables Stage 1.5 Map 2 2020 Si So I noticed no my drive tonight after reviewing the data log that I am getting 3-5 on the knock retard when MAP pressure exceeds like 8 PSI.

  8. Trying out new Octane Booster (Boostane Professional)

    So I have been using STP Octane booster which I have actually had decent results with. No real negative effects I saw and no MMT to foul your spark plugs but doing more research Boostane Professional kept coming up. Also VP Racing Octanium but that stuff is stupid expensive. Ill keep this post...
  9. What is the Fastest you have Ever "Theoretically heard" of an Si with a 1.5T going

    I know the factory governor kicks in at 136 MPH if I am not mistaken. I also know you can remove that restriction with an ECU flash. Just curious what is the highest speed you have lets say heard of an Si with a 1.5T go and with what mods and tunes? I am just wondering what the upper speed limit...
  10. Installed my Corbra CAI yesterday and the increase in power was way more than I expected.

    Wow. First drive I took after installing the Cobra I could feel the increase in power plus the temperature delta between pre intercooler and intake is down by 20+ degrees. Awesome. One question is since the intake filter is in the wheel well with no vent would cutting a vent of drilling a...
  11. Should I get paranoid at odd insane high blips in STFT 2020 Si TSP tune

    I did a log tonight driving and everything seemed okay. Hitting boost targets, knock seemed okay except for one instance where it registered 10 knock events in literally a second but on a 20 Min drive had 48 logged knock events and some misfires which I know to expect now. What I do not get is...
  12. Boomba Civic 10th Gen 1.5T Engine Dress up Kit

    Not bad really. Looks sharp. Better than stock and pretty easy to install. Worst part was Dip Stick Handel. I wish they would’ve just charged a little bit more for the kit and included the precision aluminum dipstick. For the dipstick you have to get the metal piece out of the plastic and for...
  13. So I am gonna run my Si in the California Gumball Rally in October

Figure it will maybe help me promote my own business and if anyone wants to send me stickers be more than happy to run them on my car and hey if anyone is interested in a feature sponsorship Ill take free parts and sell out a large bit of real estate on my car but really I...
  14. 1.5T What is the consensus on running a Hybrid Blow-off Valve

    I know there is debate in the community on running the sound plates and even the bolt on BOVs but what about a Hybrid that recirculates some of the air and vents enough to atmosphere to get that cool sound. I would imagine its gonna cause still a bit a a rich condition since you are loosing...
  15. Pherables is awesome

    Just gotta shout out Pherables. Their customer service is top notch and they take care of their customers. I am very impressed and grateful and the tune is as I have said before awesome. Highly recommend.
  16. Should Honda have kept VTEC engines in Civics or is the 1.5T a welcome change?

    I mean I guess tuners have been throwing blowers on Honda engines long before they came out with the 1.5T but to have a factory fresh Civic that is not NA with VTEC was strange. IDK, I think VTEC engines were for sure more reliable the tech was tried and tested for decades but the turbo is fun...
  17. Anyone here done a DIY Clutch swap on 10th Gen Civic with MT?

    Im just wondering how much of a pain it is to drop the trans-axle. I have done clutch jobs before on other FWDs with a Transverse orientation the last being a 2003 Saturn Ion and it was a pain in the ass. Had to take half the dame car apart including the front suspension including the struts...
  18. Tune Question about GOD Mode on Pherables tune

    So I have been running the Pherables tune with GOD mode and it rips. I have heard that GOD mode can cause damage to your engine if used excessively and what not but I have been doing my own experimentation and with GOD enabled my STFT remains fairly stable during decel between 5000 and 3500 RPM...

  20. Si Just got done trying out the Pherables tune for the 2020 Si. Two Thumbs UP

    They were cool enough to send me the updated tune when I bought the old tune for the 2019 civic and realized I could not flash it to my ECU. They told me initially a couple of weeks but within days they sent me the tune just today and it rips. Great responsiveness, Boost is on point and engine...
