The guys here will give you a good indication of what the best options are. To begin with, think of the engine like a pump. the better the flow in and out, the better the power output. Therefore, get as much air in as you can: - A decent Cold Air Intake (CAI) and a good panel filter - More boost via edit Add fuel to ensure you do not lean out as the air/fuel mixture needs to be within specific paramaters to produce good power AND not be detrimental to your engine. Thge standard injectors will soon run out of puff and require replacement with larger units. This should really be done as a part of the first round of mods. It will allow for more boost and, if you buy a decent set (like the Siemens), they will last well into stage 2 and 3 of your mod process. On the outflow side, a decent exhaust will be a worthwhile investment, HOWEVER, the biggest restriction is the standard cat. Replace this with a large bore, highflow unit will get you started. All of the above require the engine management system to be re-mapped, to command more boost, change timing and allow for the bigger injectors. Do more research, and choose your hardware and tuner wisely. Doing sso will get you close to 300RWKW (safely) with your $3k spend. Hope this helps
