I'm 17 years old just got my first 2002 Subaru WRX 2.0L. It is BONE stock and I need some educated answers on how to safely upgrade it. I'm not looking for 400 horsepower or an engine rebuild. But stuff like turbos, intercoolers, fuel injectors, exhaust systems, etc. Any ideas or experience please let me know o what to do or direct me to specific parts. Thank you so much!
