All the typical add-on will work just fine for the s2k, but I haven't seen any that went for the cam, pulley, and ecu, which is typical for a civic (eg,ek,ep) to gain greater respond & HP to the level of a s2k engine. Anyway, the combination of cam, pulley and stuffs will cost you a small fortune, may as well go straight to the supercharger system.
So, do buy the 07 model and get all the plug & play parts and leave the internal & ecu alone until months down the road when you think you really needed them. Good luck
