Actually I get significantly better mileage in the WRX no matter how I drive (or how I drove the STI)...
 
And my whole point is I don't want to do any non-manufacturer modifications. So adding my own sound-deadening material or my own MP3 player jack would be against that idea.
 
And I'd only want to add new parts to my new car so junk salvage would not be an option for me as a source...

Even though SPT/STI parts are built by Subaru of Japan, they are not sold for US subarus through official Subaru channels, are they ? I believe they are imported into the US through non-official aftermarket channels and will not be warranteed by Subaru dealers, even if they are willing to install them. Maybe the exhaust or so may be through official channels but that has little if any impact, on the driveability or performance. I could be wrong and things may have changed in the recent past...
 
The SPT suspension parts will introduce a harsh ride to your stock WRX. A couple of friends of mine have installed those parts and even though it sharpens handling response a bit, it is pretty harsh when compared to the stock setup. One of them has put on max performance summer tires and the ride is bone-jarring.
 
I personally feel you should have kept your STi. People who know about these things, realise that the STi is a completely different beast from the WRX, even though on the surface both employ a similar 2.5L turbo engine and both have AWD. In fact, the WRX is closer to its 2.5i brethren (other than the turbo engine and the rear viscous LSD), than the STi, surprising as that sounds.
 
The few thousands that you pay additional for the STi over the WRX Ltd is worth every penny and more. The more powerful engine, the MUCH beefier 6-speed transmission, Front/center/rear high-end mechanical differentials, HIDs, MUCH beefier/durable/sharper-responding/stiffer world-class suspension that is tailored for the high-end differentials, high-performance Brembo brakes, high-end BBS alloy wheels, Quicker steering Rack and ratio, again tailored for the sharper responses from the high-end suspension etc, etc, etc. JMHO.

Hmm ... well something must have gotten confused in the thread ... my initial point was that I had no interest in changing my car's suspension. Only air intake/output parts like the SPT exhaust components which, it seems pretty well agreed (here and with the dealer), can increase power substantially. (And possibly small "accessory details" like the HID's, etc.)
 
But no, I have no interest in otherwise changing the car's drivability. I wanted the WRX ride. I also prefer the appearance details (the decklid spoiler, the WRX wheels). The WRX transmission is also a lot more user friendly than the STI's, although that could be related to the stiff/notchy short-throw shifter option my STI had, which my WRX does not have.
 
Oh, and I'm getting better gas mileage than I expected. The published 18/24 for the STI vs. the 20/26 for the WRX is deceptive. I'm typically getting 4 mpg more with the WRX.
 
Honestly though, after a couple months, it's highly unlikely I'm going to modify the WRX at all. Looking at what I still owe on the car, my financial interests would be better served by just paying it off.

I heartily agree with this assessment. Enjoy your car. The only 'modding' I would make if I were you, would be to change the tires that came on the car. Nothing else.

I'm still sorely tempted to get the Homelink/auto-dimming/compass rear-view mirror accessory installed. My STI had it and my WRX has only the auto-dimming/compass mirror. After a couple months with Homelink I'm spoiled by the convenience and I miss it (and the storage is so limited inside that car, it would be nice to have one fewer item -- my garage door clicker -- cluttering it up).
 
But then again that's not really a modification per se. Just an option present on some vehicles and not others.
 
The jury is still out on that one anyway. And I don't mind the tires. At least, as all-season tires, they should last a while.

I have had my 2002 for 5 years now and let me tell you that I know where you are coming from with the "only factory mods" sentiment. I used to feel the same way but realize Ive just been a puss so I started doing my own mods, I suggest if you do the same... screw the warrenty, you wont need it (trust me, the wrx is rock solid). BUT I have to say that the wrx is a performance car at heart and I just dont understand why you wouldve shunned the sti for a wrx... thats just rediculous. If I wanted a more tame luxurious ride I would get an infiniti or a bmw. My .02 cents

Electric exhaust by srt8u

I was concerned on my WRX about exhaust noise, so I got the electric exhaust system. I love it! Plus my girlfriend will ride in my car again since I reinstalled my original exhaust back on. I totally control how loud I want it and it pulls like crazy when it's fully opened up! I got from rolloutedition.com

In my experience the heat of your exhaust kills these electric cutouts in short order. Not to mention they are completely illegal for street use.

I have a 93 impreza L m/t 1.8L and would like it to become an ej20t dohc turbo. will this ever happen, and if so how much is it likely to cost in time and expense? this is not something I expect to happen immediately or even soon but figure i should start asking experts now before im neck deep in an engine switch that will never work

8k-10k by paisan

8k-10k to make it into a 2.0 WRX beast. That's soup to nutz, worst case scenario. But there is a lot to take into account on doing a swap.
