I'm in the northern part of the state (ATL) so I'm looking forward to stretching my Si's legs through the mountains when life returns to a new normal this Summer. I've done new tires (Michelin PS4S) and will do the 27WON Front Strut Tower Bar and maybe the Whiteline 22mm RSB but every time I think I want to do a CAI and TSP Stage 1 I read threads like this that make me think that a good tune and maybe intake is the limit for reasonable with this engine. It seems that after that you have to upgrade to say a CTR clutch retrofit that with install is close to $2500 if you go beyond a tune/bolt ons. Then you have to do a turbo upgrade to really get gain anything on the higher end of the revs, so you're now in another $2000 at least with labor. I dunno....Well, I know my Z32 would run a 13.5-14.00 consistently with stock boost. My Civicx with a 19.5/21 basemap w/quicker spool and better throttle response is noticably quicker than stock but would not be as quick as my Z32 even at stock boost (though that might not be 100% fair as there's more done to the Z that just more boost). I've seen a few YouTube videos with reflashes putting a Civicx around a 14.25-14.5 w/a CVT, though it also had an intake. Perhaps a 14-flat is possible.
0-60 times on a FWD car are never all that impressive. The SI runs a mid-6... pretty much just like how SIs have been running the last couple generations.
If you look at Vits blog, you can see how the Hondata and Ktuner maps don't do a great deal to 5000-6500... essentially nothing after 5800 RPM. Thats where you'd be staying after a launch running 1/4 mile. His Stage 1 basemap is a definitely improvement over the regular Hondata/Ktuner ones, but for any big power improvements up top, I'd say a tune is mandatory... or running E85 w/the ethanol sensor. Adding boost to this tiny turbo does help w/midrange power and torque drastically, but it chokes out at high RPM. Still... again, on Vits blog he makes impressive power on the stock turbo with an actual tune.
If you do a basemap reflash only and crack into the 13s, I would say you're a great driver.
In southeast GA... I'm pretty sure the closest strip to me is over 2 hours away so... yeah, it won't be me.
To me, the car shines on a twisty road, keeping revs between 3000-6000 RPM. I had to drive from SE GA to Atlanta the middle of last year. I ended up skipping I-95 and I-16 and cut across the state on county roads and state highways in my 9th gen SI. Looking forward to my next reason to do it in my 10th. Maybe I could get my old lady to go to a strip... I think there is one near Macon. Hell... she might out drive me, though she can't launch a car to save her life. She'd probably get a 3 sec 60 ft.
A blast from the past. That post was before I did anything to my car. About $5k later my car is totally different. A guy with a car like mine is now pulled out his passenger seats, put slicks on and went 12.6 seconds in the quarter. The first mod was a Ktuner. Slippery slope!Was looking at hondata and have
Not seen any information that would
Make me want it for just a tune with no mods have a 2018 coupe si stock
And my 0 to 60 is around 5.5 to 6
Stock with only k n filter any hondata tune on stock coupe doing any better
