bolt on mods or internal?

[Red B16A]

What do you guys think sould I go for bolt on mods or for internal mods to the engine? For a B16A Jdm engine, I already have a cold air intake fron AEM, and trying to go naturally asperated but dont want to spend over 2,000 for now. Tell me what you think.

Well Ive already got the cold air intake and a Greddy exhast, but was thinking of getting Header, Type R pistons and a stage one cam. My only worry is I dont have any specs on the motor and dont know if I should keep the stock vavles, springs, and retainers or do I also need ajustible cam gears.

when u change the cam, its always best to change the entire valvetrain to match what u buy.
