I posted the list below earlier of my wish list (my car is a 2.0T so application & prices might not be applicable to your car) for an idea of mods you could consider.
PRL Civic Type-R FK8 P600 Drop-In Turbocharger Upgrade $2649.99
PRL Plug ‘N Play Flex Fuel Kit $499.99
PRL High Volume Intake System $399.99
PRL Street Downpipe & Front Pipe Combo Upgrade $829.99
PRL Intercooler Upgrade $599.99
PTP Turbo Blanket (PRL) $135.95
K-Tuner or Hondata $649.00/$695.00
Mishimoto Baffled Oil Catch Can $270.00
Borla Cat-Back Exhaust System $1,049.99 (PRL)
With that list or any performance mod you may consider there will be one caveat.... if your car is an automatic (CVT) then you will want to be careful how much performance/power increases you do as it (CVT) is a weak point.
