Default I want more power out of my 2002 2.5rs...

I have had my Impreza rs for some time now and so far i have the normal stuff.
Weapon r secret weapon intake
SRS ebay catback exhaust
fake Borla headers
Rallitek plug wires
NGK Platinum plugs

I want more power and i have been looking for a tuning device like the perrin or cobb but cant find any. I was wondering what I can do to get some extra powa!!

Also could tighten up suspension, which helps with cornering faster.

+1 on a NA tuner.

Call Delta (down time, options on grind), or buy from Rallitek (cores available, only one choice for grind).

Another area you could check out are phelonic intake manny spacers. and you could take your car to a nice suby tuner and have them tune it cause subys are tuned so restricted.

I wouldn't bother with deleting the cat unless an exhaust you buy already comes without one, i.e., I wouldn't go out of my way to do it. Personally, I can't stand the smell of catless and I think it makes exhausts sound raspy. There's a thread on here showing that going catless did pretty much nothing. I don't feel like searching for it.

+1 for delta cams, i have them and it's made the biggest difference. I did them with a Exedy LW flywheel and clutch so it really livened things up. You will want some tuning done if you are going to do cams, I don't' remember if you can do open source tuning with the 02, it's been a while since I've looked into anything like that but I know it's not avail on my 04. I already had the Perfect Power 6 Piggy back so i just had to run the stage 3 map they Rallitek sent me. But not to be a downer but no matter what you do there will never be quite enough power and eventually you will run out of stuff to do and it get really expensive at that point, that's about where I'm at now.

If your car is equipped with EGR the spacers will cause the tube to be too short. You will have to extend it.

You can also take the coolant line off of your TB unless The IACV is built into the TB its self.

Cat delete or high flow cat can give u some gains if u dont wanna run catless.

lightweight pulley's orrrr get a lightweight flywheel. it'll rev a lot faster then with a lightweight pulley.

but seriously if you want POWER then u should just get a wrx. RS's are more of a fun driver then anything. The most power u could get with general mods (including internal) is around 230 (and thats probably to the crank). The most anyones gotten out of our engine is about 300 hp. But thats a specific build and not even worth it unless u have an unlimited budget.



I recommend lightweight flywheel.

A 2.5 RS will pretty much beat a WRX on a rallyx course any day of the week. The lighter weight, better throttle response, and instant torque make it a lot more fun to drive as well. They are actually really fun at autox too but currently not classed well.

You can knock close to 75lbs off the front end of a 2.5 RS pretty easily which makes it handle even better.

light weight battery -13+
light weight bumper beam -20
WRX hood -22
Lightweight flywheel -10??
headers -5??

Keep your RS brakes since they are lighter than WRX rotors and work absolutely fine unless you plan to use the car for track days. (in which case, you only need a pair of good WRX rotors and caliper brackets).

Don't forget how much money you're saving in gas since the 2.5 RS doesn't require premium.
