  1. Si Aftermarket Valve springs and retainers

    Titanium is lighter than steel. That means the valve system is lighter and can rev a bit higher before valve float.
  2. 2016 civic questions

    I installed an RV6 catted dp on my stock turbo Si. It cut the turbo response time in half! I also love the increase in sound of my exhaust.

    Best 10th Gen Si daily driver!

  5. 1.5T How much of a difference does a performance Intercooler make V. Stock

    It mainly depends on the driving as to how much benefit you get with a performance intercooler. It depends on air flow across it. With stop and go driving in the city there will only be a marginal benefit. With highway driving or repeated pulls at a drag strip it will be fantastic to keep...
  6. Si A quiet exhaust?

    It was easy to install. The shop charged me $80. It fits on a coupe. I have a sedan so they had to extend the three tips. They just welded on some new hangers.
  7. Si A quiet exhaust?

    Type R exhaust on Si sedan. Three videos. Including drive through neighborhood, take off and drive by. With Catted RV6 dp. Type R Exhaust with catted dp
  8. CEL after Catch Can Install

    I have the Ktuner V1.2. I just go to the ktuner menu in Tunerview where you flash and it has options to scan codes as well as clearing codes.
  9. Flex fuel or turbo upgrade?

    I decided to get flex fuel and not a big turbo. I did it because I wanted the lower end torque for daily driving. Ethanol gives me more torque when the turbo isn't even on pressure! Makes driving around town more pleasant. I feel like my engine has more than 1.5L. The stock turbo comes in...
  10. 27won iat/external temperature difference

    Actually they are very different. As you said the PRL pulls air from the fender. The 27won pulls air from there AND has a slot in the filter box that pulls air from the hot engine bay. It mixes the two air sources. Runs hotter than the PRL Cobra.
  11. Anyone Running the aFe Catted Downpipe

    I was told from an inspector here in Texas that they check for readiness flags. She told me that Ktuner disables the the O2 system software so it doesn't come up ready. No Cell but also no readiness flag. She said it would fail inspection. She extended her O2 cable to screw the O2 sensor...
  12. PRL BIG TURBO. Who’s running it?

    27Won says their TIP gives them 9 more hp. The W1 has a better lower end which may be most useful on the street. The PRL used to have a lot more turbo lag, but I haven't heard reports from users or tuners at how the electronic wastegate helps PRL's turbo lag. Maybe there isn't as much...
  13. PRL Downpipe 3"

    Posted dyno charts show a nice power increase across the board. The biggest differences I noticed when I put in a catted RV6 downpipe was that it was a bit louder and turbo lag was much less. Going steadily along at 50 mph in 4th gear it took 2 seconds to reach 10 psi when I went full...
  14. Type R Clutch/Flywheel in an Si

    Eman quoted me a price of 17 hundred installed at a shop about a year ago. I'm sure that's a little more now. I don't remember if that included the CMC.
  15. Tips for getting ECU Number

    Just take your cell phone and stick it into the engine compartment near level with the sticker at the corner of the engine block. You can then take a picture and read it. Don't drop your phone.

    Oops! I was thinking you had a base 1.5T civic. Sorry, I don't know anything about the NA 2.0.
  17. Recommend Mods

    I recommend getting a Ktuner 1.2 from TSP. They give you a free TSP Stage 1 tune. It is a very refined tune. The exhaust on the car is pretty free flowing. I would only recommend a catted downpipe in the exhaust system. That will allow your turbo to spool faster and give a bit more power...
  18. E85 questions

    I am sorry to take so long to answer. Tunerview lite just connects via Bluetooth to Ktuner. Tunerview app on phone may have more connections via the phone's internet connections. I am not certain about that. It is just that some versions of Tunerview may be able to connect to google maps. I...
  19. E85 questions

    Looking at the Ktuner help file on the Ktuner website under Tunerview Lite, it says it supports 2019 cars. Yes you need to install hondahack. The ethanol sensor in the E85 kit you buy will send a signal to the car's ECU to the tune you install with ktuner. That will adjust your timing and...
  20. E85 questions

    I have the Ktuner 1.2 with TSP stage 2 tune and a TSP ethanol kit. The kit is quality, but the PRL kit is killer! It wasn't available at the time I got my TSP kit. I run E35-E40. I love it! I like the Ktuner 1.2 over the 2.0 as I can run the Tunerview app on my head unit and it talks to...
