  1. Possible belt tensioner sound?

    Howdy yall Up to 88k miles now, tensioner showed past due for a belt replacement so I grabbed a mistoboshi brand one because oem availability is slim near me, I replaced the belt, the hasport motor mounts mean I was able to do it just from the engine bay and the flap held by two clips on the...
  2. New Hampshire FS: New kzcmc

    Howdy, I bought this probably around October '21 and many things never happened. Never got a custom tune, so I never put in a new clutch, so I never needed this kzcmc made by Eman. With how life is going, I'd rather it go to a good home than sit on my shelf. Asking $275 obo I'll add a photo...

  4. Is it worth it to put lowering springs on high mileage struts?

    Howdy, I've got a 17 civic SI with about 82k miles right now. I wanted to lower it, and I wasn't sure if it would be worthwhile to throw lowering springs on for some time or if I should go full coilovers right away. A local 10th gen si to me has just as many miles but has been riding on D2...

  8. SOLVED: Car pulls left after alignment

    Howdy, Trying to chase down some suspension gremlins. I was due for tie rods and ball joints, so I picked up some moog inners, honda OEM outers, and SCP static ball joints. Install went OK. Got the car aligned at my local honda dealership, they gave me a big stink about "modifications" but it's...
  9. Massachusetts Trade my catless RV6 plus $ for catted RV6

    Hello, figured this is a long shot. Looking to trade my catless RV6 downpipe with the vband clamp, for a catted RV6 catted downpipe with vband clamp. Rv6 stopped selling the catless due to the EPA, and I don't want to switch & swap for each inspection, so I'm hoping for a trade with $ on my...
  10. Si Troubleshooting fuel trims before performing MAF scaling

    Howdy, I'm trying to chase ghosts, namely fuel trims. From most information I've been reading, short term trims should be within 10% positive or negative, and long term much closer to 5% positive or negative. I keep seeing everyone post their 0 to -3% fuel trims and so I want to look into it...

  13. Massachusetts Looking to buy lunch for a local who lets me ride passenger to hear their AWE or Invidia exhaust

    Howdy. Recently did a DIY muffler delete and it's the tone I want, but the cabin drone is a little much around 2.5K rpm to 3.5K rpm for a "daily". Before I drop money on a REAL exhaust, I'm looking to see if someone will let me hear their AWE, Invidia, or similar exhaust, to help me make a good...
  14. Si Broken transmission stud - replace or full send?

    Upgraded to the 62A hasport motor mounts all around this weekend. Install went good, major improvement for the car. During the install, when removing one of the nuts on the studs, the stud snapped. Was a big "oops" moment as I'm holding what looks like a bolt. There was plenty of thread on it...
  15. Raceseng plate mount on the SI

    Howdy! I was looking at different plate mounts for the 10th gen platform, the raceseng specific one was appealing since it can double as a towing solution with an appropriate attachment. I was having a hard time finding what it looks like on a sedan/SI, the only two images I can find for 10th...
  16. Si Fixing clutch lever squeak

    What is the best way to diagnose and fix this squeak? Is intermittent depending on temperature, humidity, and temperature of the parts. Pulling away from stops, the loudest thing at the intersection is my rubber duck clutch lever. Does the slave cylinder need to be regreased, or the point of...
  17. Lowered sedans running 18x9.5 +38?

    Hello friends, I'm currently running 18x9.5 +38 wheels and 255/35R18 tires, which give a bit of poke on the stock suspension. I have a three finger gap on all three corners. Looking at lowering options, can't be more than 2" for state inspection. Will come through the lowered thread but does...
  18. Ultra Racing strut tower bar doesnt allow strut nuts to be fully threaded

    Howdy, 17 civic SI sedan, When installing the ultra racing strut tower bar it looks like there is not enough stud to thread the nuts on. I made sure its torqued to 46 ft/lbs and added paint marker to ensure it's not coming undone. When I look for other pics of mention of this, it seems to be...
  19. Si Short term fuel trims causing knock in cylinder 1 at low throttle

    Hello! First, I am aware that knock control is more important than knock count in our cars. Just trying to make sense of phantom knocks that are reoccurring, incase it is an early sign. I'm using Ktuner V2 with the TSP Stage One+ on a 17 Civic SI, with PRL CAI and Intercooler. My plugs are OEM...
  20. Unable to clear codes P2127 and P2122

    Hello! I installed the Acuity Throttle Pedal Spacer. Part of the instructions is to unhook the connector. Realistically, you can install without doing so, but I didn't want to put tension on the wires, so I used a flathead to pry the connector off, like what it shown in the video install...
