I picked up a clean as heck 2002 WRX about a week ago. It was tuned a few months ago. Not stock, has intake, exhaust, 3in intercooler piping, ball bearing turbo thats ported, Clutch, and a few others. stock trans. 5 speed. I can hear a knocking/tapping sound very slightly when holding the throttle completly still from about 2600rpm to 3400rpm. unlucky me i am guessing its rod bearing. i was thinking if it will make it till March i could daily my 240sx and tear down the subie. i was thinking while its apart to do some forged internals for extra saftey. I could dump maybe $2000 into parts and do all the labor. Cars at 320hp and i am fine where its at. it is my Daily driver and i want it to be my daily for another 100k miles. what do you guys suggest?
