You have already used your 300 HP to your best ability? What I mean is not only using 300 hp to find out what your quarter mile/0-60 times are .. but learning its power curb, learning how to handle an AWD can in case of an emergency.. how to take/maneuver curves(ie.. optimizing the use of your all wheel drive mechanism).
Since purchasing this beauty a WEEK ago.. you are already hitting the rev limiter???
Hmmm.. Please help me answer these questions so that we can better help your needs ...
Thank you so much

Gary,
Cheepest? Be careful with that word, you just spent 35K on a *** Import Car - you didn't start cheep so why finish it cheep. Cheep = Honda, not STI. That said, it depends on your goal - find your goal, build you car accordingly. Every car will have bottlenecks (parts that arn't able to support your next power level), replace these parts in order of how the bottleneck affects your power.
Example - who cares if you have a huge turbo if you don't have larger injectors, fuel pump and rails to support the increase in airflow?
Start with engine management. Go with EcuTek or Cobb Accesport - these allow you or your tuner to remap your stock ECU to take advantage of what the car already has stock and take more advantage of bolt on components you put on later.
Next, look to your intake and exhaust. Perrin makes a great intake (needs ECU tuning) called the Big MAF. Then go turbo back exhaust. Don't wory about your uppipe - there is no cat in the STI.
After exhaust and intake, your injectors will be running close to 100% and its time to upgrade your fuel system. Larger injectors (PE or Perrin), I would recomend going with injectors that can flow 800 + cc. Fuel pump (Walbro 255l/hr), fuel rails, stainless braided lines.
This is a stage 2 STI. You will probibly put around 300 to the wheels with this set up. There is no stage 3 really.
Stage 4 is IC upgrade and Turbo. Some people try to stick with the TMIC (top mount intercooler), but I would recomend going with a large FMIC (front mount). You will be able to pull larger HP with a FM. Turbo upgrade is up to you - be careful going too big - you will loose spool up and drivability.
Thats power. Don't forget about suspension. Stock STIs have built in push (front wheels break before rear wheels) and is not the fastest way of moving the car around a corner. Cusco, Perrin and others make adjustable sway bars to counteract this. Combined with solid coilover dampners (Cusco, Tein...) your car drop center of gravity, decrease role and cut seconds off of your lap times. Other cheep but effective mods are shifter bushings (eliminates slop in your shifting), short throw shifter.
Thats my recomendation... oh and take the time to break that beautiful car in!

I've had my car for a good 9 months and didn't touch my 05' up till now pretty soon I'll be running stage 2. Only a week of driving isn't enough to get "used" to a car. And also there is no cheaper way to get power unless you got the cash to put into your vehicle. I feel sorry for your car if its brand new and only a week its been improperly broken into.
