thanks for thinking of me when starting this thread.
I'd suggest you sell your car and get a car more responsive to modifications.
My reason is that if you have a civic EXi and wish to fit branded turbos etc to it you'll spend alot of money on it and at the end of the day you'll spend enough to have bought/leased an EVO or RX8.
You're better off only doing (so called) stage 1 mods to your EXi and leaving the car alone, but if you are planning on going further my honest opinion would be to change your car first.
