Hi guys,
Basically, my question is how do i mod it to get the HP and the control of a Civic SI?
I know i can get easily
- Hondata and flash the ECU
- Tires + Rubber to 235/40R18 91W
- Larger brakes
Will these upgrades above help?
I am not sure if the Active dampers suspensions and Limited-slip differential is gonna be a easy or cheap upgrade
Below is the full list of difference from Wikipedia on current Civic SI (i removed the items that are not performance and control related)

Below is the full list of difference from Wikipedia on current Civic SI (i removed the items that are not performance and control related)
- engine output increased to 205 HP @ 5,700 RPM (SAE net) and 192 lb-ft torque @ 2,100-5,000 RPM (SAE net)
- higher maximum boost pressure (20.3 vs. 16.5 PSI)
- lower compression ratio (10.3:1 vs. 10.6:1)
- higher-capacity MHI TD025 turbocharger (9-vane vs. 11-vane)
- helical limited-slip differential
- larger front brake rotors (12.3" vs. 11.1" vented front and 11.1" vs. 10.2" solid rear)
- two-mode damper system with normal and firm settings
- SPORT mode replaces ECON mode - increases suspension damping, reduces power steering assist, increases throttle sensitivity, and raises the activation threshold of the Vehicle Stability Assist system
- 235/40R18 91W tires vs. 215/50R17 91H
- 7% stiffer front spring rate
- 18% stiffer front upper damper mounts
- 7% stiffer front stabilizer bar rate
- 32% stiffer rear spring rate
- Solid vs. fluid-filled front and rear compliance bushings (rear shared with the Type R)
- High-stiffness rear upper control arms (shared with the Type R)
- 26% stiffer rear stabilizer bar rate
- center-mounted polygonal exhaust outlet
- higher-flowing intake system
- 23% higher-flowing exhaust system
- 10% shorter shifter throw
- revised shift linkage
- increased rigidity of shifter bracket mount
- additional items in Driver Information Display including G-force meter, turbo boost gauge with PSI indication, lap timer, throttle percentage, and brake pressure
