NGK Spark Plugs (better idle, possible HP increase)
Underdrive Pulleys +6HP

Camshafts +15-20 but expensive

Just to clarify your HP quotes here: an exhaust will add 12RWHP at best with a properly built dual exhaust, cat backs normally gain around 5. The ECU tune wil not you no more then 18RWHP without larger injectors, regardless of the octane you use. You can't make power without the fuel. Just an example with the injectors added to the CAI and ECU tune we picked 29RWHP, from just adding injectors. That doesn't mean injectors added to a stock motor will add 29HP, it's a ll about harmony.
With a spot on tune and the stock intake and exhaust manifolds, 300HP will be extremely tough to get, but doable. A new manifold and headers will really wake this engine up.
