04 unmodified wrx, what mods should I start with?
Yea, just bought a 2004 WRX and I want to know the with what mods should I start with to get horsepower to drift?
The first thing you should do is get a new up pipe, downpipe, exhaust and accessport.
change your air filter, either keep the panel filter but upgrade it to like a k&n 1...if u wanted to spend the cash a CAI( cold air intake) pipe..pretty much it's a pod filter but instead of in your engine bay it's in the gard so it's getting fresh cold air instead of hat air from your engine bay...maybe invest is a aftermarket plumb back BOV, a boost tee so u can up the boost a lil...but not too much..the standard engine wont be strong enough for a sustained anything over 18psi, 3inch exhaust also works well..from the turbo back it really depends how much u wanna spend...like u could go straight and get a ecu tune.. but for a estimated 30kw gain out of stock everything wouldnt be worth it yet untill u have the said items yet...
Nathan is right.. cant say more
ECU tuning (COBB TUNING is great)
listen the current computer will control the valves at the same rate COLD AIR INTAKE OR NOT THE COMPUTER COMPENSATES FOR THE ADDITIONAL AIR, there is no horse power gain (i dont care what a box says), until you leave the intake valves open a longer duration....reprogram the ecu (called chipping it) adjust the cams, (larger), increase the exhaust size,"headers", and to drift are you on dirt or road? spent a few years in the drift scene, so I have much background in the style, removing the front drive shaft works best, it's almost impossible to get a awd car to drift on road without the ground being wet., dirt is easier, but still rear wheel drive is recommended, start on dirt, it is much easier and cheaper on tires, then see if your vehicle has a heavy duty wheel bearing/axle kit to sustain the side pressures, or all the horsepower in the world wont help the rest of the drive-train.....
Ugh WHY would you modify such a beautiful, clean car? I weep for humanity that all these excellent cars are being ruined by children.
