  1. What kind of MPG are those of you getting with 450 - 500 WHP?

    Currently running Phearable phase 2 with downpipe and intercooler. Est. 375 WHP, when I drive it aggressively in city driving I get around 20 MPG. Wondering what those of you with a bigger turbo and upgraded fuel system pushing 450 to 500 WHP are getting? Thanks for any info, thinking about...
  2. Please assess my mod plan for my mostly stock FK8 running Hondata 93 Octane Tune

    Car Current state: Hondata 93 Octane Tune, 19 inch rims, rest stock Overall endgame objective: I'd like to run 400 to 450 WHP reliably as a daily driver with a rare track day maybe once a year, nothing too serious on the track day though so I wouldn't be pushing the car for time. I do live in...

  4. Good price to target to get good quality 18 inch wheels for the Type R?

    I'd like to pickup some durable 18 inch wheels and keep them close to $200 per rim. I was thinking something like the Enkai Raijin for $220...
  5. Why I traded in my Civic X Si

    This isn't intended to be a bashing post. I’m just going to throw the reasons I traded my Civic X Si in for a 2018 WRX out there for discussion. The Si is a very good car that is a fantastic value. I’m going to start off with a couple great things about the Si. Starting off with what the Si...
  6. Other than clutch,What extra upgrades or maintenance to support a higher psi tune?

    Other than the obvious clutch, what other upgrades or extra maintenance should be considered to support a 23 or 25 psi tune on this car to drive it for 100,000 miles plus?
  7. Always high idle RPMs when starting cold car... is this normal?

    I'm always hitting high idle RPMs (1400-1500) when starting the car in the morning, then after about a minute it's down to typical 750-800. Is everyone seeing this or should I have it checked out? BTW, I live in Florida so it's not cold.
  8. Would a mild Ktuner tune impair longevity?

    I'm looking into getting a Ktuner for my 2018 Si. I know we can only guess at this point but any thoughts as to how the +1.5 or +3.5 psi tunes would affect engine longevity? Would any other parts need to be swapped for mild tunes like this? I'd like to get 150,000 miles out of this car so I...
  9. Why does the stock 2017/2018 Si seem to underperform on the 0-60 & quarter mile relative to specs?

    According to this post: http://blog.vittuned.com/introducing-the-2017-civic-si/ and other dynos I've seen it seems that Honda slightly undersold the torque and horsepower specs on the 10th Gen SI. We're talking ~220 ft-lb of torque observed at the wheels and 205 HP at the wheels, which is...
