Default 2002 RS mods

What can I do for the biggest hp gain for my 2002 Impreza RS? Every time I look for anything it is only for 98-01 year models. i can get the Borla headers. Don't know if it would be significant hp gain. What turbos are available for 2002?

I think the 2002+ RS have the best of both worlds, you can use WRX piping, exterior mods, and what not, but use most 99-2001 engine parts like headers and what not. There are a lot of options for turbo kits, bolt ons and what not. Just look around in the N/A forums or find a turbo kit to bolt on

i dont think anything would give you big gain by itself or well anything at all

but doing an intake, headers, and cat back will help give you some powaaaa

Lightened Crank Pulley: Mr. Josh's or Unorthodox ($80-125)

Lightened Fly Wheel: Exedy, Fidanza, (not sure who's best or $)

Intake: Used/New Ganflow + K@N Panel (~$100)

Headers: Borlas for sound and price ($250-300). Or, equal length for power.

Exhaust: Any 2.25" midpipe (custom or Stromung $40-150) +
cheapest: WRX Axleback ($25-60)
Looks+Power: Brullen, Scoobysport, Stromung ($300+)


Most of these mods shouldn't throw a CEL. However the Borlas may, probably not. All this ain't gonna make a sports car, but pretty dang close.

Don't forget the carbon fiber. And remember folks; Real Carbon fiber gives you more HP while fake Carbon Fiber gives you mad Torque.

I have the dyno chart to prove it.

Do a set of cobb's stage 1 cams. they'll work with stock valvesprings, and make more power than an intake, header and catback combined, and only cost 500 beans..Trust me on this one. I've tried almost every gadget available for the EJ25 motor, and have already ordered my race motor for it (270 hp; if you can afford it) and other than a whole motor buildup, the cams are your best bet. they'll give you real power, not just a 'cool sound'.

What I didn't know is that replacing the cams actually effects your exhaust sound....in a good way!!!

I have heard that the cams will not let you pass emissions, but they if they give that extra kick in the pants its totally worth it. You may also want to think about having the car tuned if you do cams, intake, headers, downpipe, and exhaust (also if you change the valvetrain with stronger springs or a port n' polish). I have heard that this will help the car idle and run smoother through the power bands. Good luck!

does this apply to california emissions? i currently have ganzflow intake, borla headers, custom 2.5 midpipe and a apexi n1 muffler. however, im probably going to put back all the stock parts when i go to get tested. i really want to get cams. and i heard that the cobb cams break and then all the metal stuff goes all over in the engine. im not sure though...just heard about some cases where people's cams broke. i dunno if its the stage 1 or the higher ones.

where oh where do I look to get a scooby sport exhaust? would Borla headers and a cobb cat back (or scooby sport) be a good combination.

borla headers are fine. I have not heard many, if any stories about the new gens cracking. The problem with the borlas is that they dont give much power. however they dont give up power and they sound great. Not to mention they are affordable. Im quite happy with my borlas.

i have only read one story where a set of cobb cams broke.

lw flywheel was definately a nice improvement.
Short throw shifter and steering wheel added a great feel to driver inputs.
rear swaybar was the most noticable improvement.

list of mods - cobb intake, borla headers, custom 2.25 unres midpipe, scoobysport axleback, gfb pulleys, exedy sport clutch, exedy lw flywheel. BPM short throw shifter w/ kartboy bushings. Toyo fz4 tires, eibach prokit springs, cusco adjustable rear swaybar, cusco front and rear strut bars, apexi safc II, apexi ITC,(both computers are currently untuned), cobb cams (coming soon) autometer a/f ratio guage, autometer oil pressure guage, momo jet steering wheel, schroth rallye 4 harness. (just used it at an autocross, felt great! no more sliding around the seats, completely impracticle for street use.)
nice improvement to the car, quicker and much more fun to drive.

Sorry Alpha_32, I meant midpipe. I was just talking with some guys who have RS-Ts and about their downpipes, catback exhausts, and upipes. I know I am a stupid ............well.....yeah.
