Aftermarket Parts & Upgrades -- NEW AND IMPROVED
Second Generation Legacy
Aftermarket Parts & Upgrades

Under construction over the next few days.

If there is something you would like added to this list, please send me a PM and let me know. I will likely not look at this thread often since I know all of this info and I have no reason to reference to I probably wont see requests posted in the thread.

If you're wondering what happened to the old version of this thread, it has been closed and removed from the stickies. The member who was maintaining that thread is no longer active. The thread was full of dead links and there was no way for us to add new / more information to it. That is why it was decided to close it down and make a new one.

When available, I will be linking the manufactures website. A simple Google search of any part numbers can find you better deals than buying straight from the manufacture.

Engine Modifications

Note : Most of this information is for the EJ25D (2.5L engine in the GT and Outback). Some of this stuff crosses over the the EJ22E, but please verify before you do so.

Turbo Swaps & Builds
Looking for massive power? This is what you need to read.

Cold Air Intake
Cold Air Intake systems are generally frowned upon on these cars. The "better" option is a hybrid style intake.

Perrin Lightweight Crank Pulley
Karyboy Lightweight Crank Pulley
These will enhance your throttle response and make your engine rev faster.

Your selection of mufflers is almost endless. You can run anything from eBay "fart cans" to Flowmasters. A popular choice seems to be Vibrant mufflers.

There are a few different options for headers out there, but the Speedy Racer headers have proven to be pretty good, and very affordable too.

Note on Borla headers :
Borla headers are a more expensive option, but they are known to crack very easy. Unless you want to waste a bunch of money, I would stay away from them

MSD Coilpack
This is almost a "must do" modification for anyone interested in performance. Better spark = better power. Be sure to accompany your new coilpack with a good set of plugs and wires.

Intake Manifold Spacers
The theory behind these is that if you space your intake manifold further away from the block / heads, heat soak will be reduced....therefor air will be cooler and more dense. I've personally never tried them because I don't think they will make any notable difference.

Group N Engine Mounts
Solid / stiff mounts will reduce your throttles response time by eliminating twisting in the driveline. Keep in mind that with these types of mounts, you will experience more noise and vibrations in the car.
Kartboy Engine Pitchstop Mount

Kartboy Oil Cap

Port & Polish Heads
The idea behind porting and polishing your heads is to allow more airflow through them. More airflow = more power.

Header Heat Wrap
Helps keep the heat from your exhaust inside your exhaust instead of radiating out onto other important stuff (like the engine and transmission).

Camshaft Grinding
There are several different options here. Depending on how you grind your cams you can get more low, mid, or high range power. Remember though, there is always trade offs. If you grind your cams for a lot of low end power, you will be lacking on the high end....and it works the other way around too.

Steering & Suspension Modifications

Note about Steering / Suspension parts :
Most of the links I'm providing are for Whiteline parts. Whiteline is pretty much top of the line. They cost a little bit more, but their parts (at least in my experience) are much stronger then the competitors and perform much better. Remember, you get what you pay for. If you want to stay cheap (and have piss poor parts), then do an eBay search for generic Chinese parts. If you want something durable that performs great, I suggest sticking with Whiteline. Some of the other bigger names are decent as well (Rallitek, Kartboy, etc)
As far as handling modifications go, swaybars are the biggest bang for your buck. The difference they make is asternomical on stock suspension. Pair swaybars with a good strut/spring or coilover setup, and you will have one hell of a good handling car.

Front Swaybar
Whiteline 20mm BSF14
Whiteline 22mm BSF19X
Whiteline 22mm Adjustable BSF19XZ
Rallitek 22mm 109578 (40-1008)
Addco 25mm

Rear Swaybar
Whiteline 20mm BSR19XZ
Whiteline 22mm Adjustable BSR19XXZ
Rallitek 22-25mm Adjustable 109325 (40-1002)
Addco 22mm

Front Endlinks
Whiteline Heavy Duty KLC20A
Whiteline Extra Heavy Duty KLC31
Whiteline Front Endlink Bushings W22259

Rear Endlinks
Whiteline Heavy Duty KLC19
Whiteline Extra Heavy Duty KLC26
Whiteline Rear Endlink Bushings E22260

Rear Swaybar Mounts
Whiteline 20mm Rear Swaybar Mount KBR21-20
Whiteline 22mm Rear Swaybar Mount KRB21-22
Whiteline 24mm Rear Swaybar Mount KRB21-24

Swaybar Bushings
Whiteline Front 20mm W0404-20
Whiteline Front 22mm W0404-22
Whiteline Rear 20mm W0404-20
Whiteline Rear 22mm W0404-22
Whiteline Rear 24mm W0404-24

Struts & Springs
H&R Sport Springs (-1.5”, -1.25”)
RS☆R Lowering Springs (-1.25”,- 1.25”)
Eibach Lowering Springs (-1.2”,-1.2”)
Saggy Butt Spacers
Cures the "saggy butt" look when you use lowering springs.
One of the biggest handling modifications you can do is tweaking your alignment for the way you drive. Here are various parts that allow you to customize your alignment outside of the stock adjustments on your car.
Whiteline Rear Adjustable Lateral Links KTA108
Adjustable lateral links in the rear allow you to dial in your rear alignment setting further than what the stock adjustments call for. These will allow for both camber and toe corrections. When using these, be sure to use a toe lock out kit.
Whiteline Rear Toe Lock Kit
Whiteline Rear Camber Adjustment Bolts
These are needed to dial in your rear camber settings if you are not using adjustable lateral links.
Whiteline Camber Correcting Lower Control Arm Bushing KCA375
Whiteline Castor Correcting Lower Control Arm Bushing (Motorsports) KCA375A
Whiteline Anti-Lift & Castor Correction KCA319A
Whiteline Anti-Lift & Castor Correction KCA319 (Comfort)
Whiteline Anti-Lift & Castor Correction KCA319M (Motorsports)
Whiteline Front Roll Center Adjusting Ball Joints KCA313
This is a must for lowered vehicles. It helps with bump steer problems and brings the control arms & CV axles back to the proper angles.
Whiteline Offset Front Strut Mounts
Provides some Camber / Castor correction.
Whiteline Front Camber Adjustment Bolts
Our cars come out of the factory with front camber adjusting bolts (upper position on the steering knuckle), but these bolts will allow for further adjustment over what the stock bolts provide.

Whiteline Front Strut Tower Brake KSB660
Whiteline Rear Strut Tower Brace KSB590Q
HIGHLY recommended for wagons
Whiteline Strut Tower Brake Quick Disconnect Set KSB790

Coilovers are hard to find for our cars. Your best shopping for coilovers for any 02-07 WRX. Here are a few to get you started though. A general rule of thumb I go by with coilovers is that if they cost less than $1000, then expect a lower quality product. If you're looking for the best of the best, I highly recommend the D2Racing coilovers. They are simply amazing.
D2 Racing
Megan Racing
BC Racing
Raceland (budged coilovers - questionable quality)

Whiteline Front Control Arm Front Bushing W51709
Whiteline Front Control Arm Rear Bushing W51710

Performance Stickers

VTEC Badge
Good for 50 horsepower

The R stands for "racing". Instant race car status with one of these bad boys.
STI Rabbit Badge
This is for those homosexual guys who rock STIs....or straight people who think their car is an STI.
Turbo Inside
If you can't afford a turbo, get yourself one of these. It will make it appear to others that you have a 400awhp car!

I know pretty much all of the options available for these cars. Over the next several days I'll be adding a little bit at a time when I get a few spare the end of the week I'll have nearly everything in this thread.
