Spoon, Toda and Mugen have performance upgrades for Honda car owners. You need a turbo set up and custom exhaust to match with the set up. 4-5k for the turbo setup and another 1k for a custom exhaust.

B18b1 Upgrades

you can always start with the intake/headers/exhaust. however if you wanna go turbo your gonna be looking at a decent amount of cash if you want it to be reliable. you'd have to rebuild the whole motor from the bottom up to handle it. as for naturally aspirated, a new intake and intake manifold, a set of cams and springs/retainers, a good header and full exhaust, and an ecu flash would be a good start

1) A "turbo" is not enough, you need a full turbo kit, will be around $4k USD

2) more upgrades? you can change your gear ratios, that improves dramatically your acceleration

3) Brands, Turbonetics is a nice one, Garret

4) As much power for your money... well.. and budget is ___?

You can try in the meanwhile a car performance simulator, there you can virtually do all the mods you want to your car and test how it performs, that way you could decide what upgrades use in real life.
