hi, everyone, i'm a newbee to a DC5R. and jus wondering few question about the modification which i gonna do on my K20A.

1. i got a Apexi air intake kit atm, and is it gonna be better if I replace by a Mugen Air intake kit?

2. what can I do if I meant on bringing more hp under a $2k$ budget?

3. also wondering is there have any specialist or mechanic on tuning DC5R in Adelaide.
