while everything hyperlinked is fully compatible with your 2nd gen, keep in mind that it is only a guide to give you a better idea of what to look for..

Transmission Crossmember Bushings - These bushings can take the torque and vibration of high-performance street and race use

Sway bar Mounts - Super rigid forged light weight alloy mounting.

Rear Sub-frame Locking Bolt Kit - These bolts lock out the rear diff. sub frame bushings to maintain alignment under extreme conditions.

Aluminum Control Arms - Reduces your un-sprung weight and deflection under hard cornering resulting in improved handling

Performance:

 

Cold Air Intake – the Ebay intake was dyno proven at about a 6hp gain over similar Cosmo Racing ($200+) intake systems

MAF Adapter – You’ll need this to affix the cone filter to your MAF

Muffler - Anything works here

Borla UEL Headers - Not recommended due to the thin walls and chances of cracking

Borla Replica Un-Equal Length Header – Bring out the boxer rumble and free up a few HP. Much better reports than original Borla’s

OBX Equal Length Header – Sacrifice some of your rumble for more performance gains.

Header Heat Wrap – Keep the exhaust hot and the valve train noise muffled.

High-Flow Catalytic Converter – Increase exhaust flow

Camshaft Grinding - Low end gains and high end gains depend on how you want them grinded

Spark Plug Wires -

 

Lightened Flywheel - Reduce weight and inertia for better engine response

[ame=http://www.amazon.com/Grimmspeed-Lightweight-Crank-Pulley-Blue/dp/B0054RG63Y]Lightweight Crank Pulley[/ame] - Get quicker throttle response and more horsepower and torque. Reducing rotating mass results in better performance.

Grounding Kit – Smooth out idle and ride, reduce noise, and free up some HP.

Engine Management – Optimize engine performance by controlling aspects such as fuel mixture and ignition timing.

Port and Polished Heads - Reduce the restriction in the engine's intake and exhaust chambers to allow more air into the system, gaining power.

Engine Pitch Stop - A mount that’s stiffer than stock will reduce the amount of forward and backward movement the engine has.

Roll Center Adjuster – For lowered cars, this replaces ball joints ad returns the control arm angle closer to stock to help bring roll center closer to CG.

Phenolic Intake Manifold Spacer - Greatly reduces the transfer of heat from engine to intake manifold thus reducing heat soak. Every 5° temp. drop = 1% power gain

[ame=http://www.amazon.com/Subaru-Mounts-Legacy-Listing-Fitment/dp/B00ANOV24G]Engine Mounts[/ame] - Less sway and flex in engine components helps put more efficient power down to the ground.

 

Transmission Mounts - Transmission Mounts Make the transmission more solid. They will give you better feel for your transmission and easier shifting.

4EAT / 5MT

Transmission Oil Cooler – Improve overall performance, and lengthen the life of both the fluid and tranny

Engine Oil Cooler - Reduces oil temperature for extended engine life

Coil Pack Upgrade –(*Important Info!) Provide a more complete combustion with a powerful spark in your ignition system which translates into more power and better MPG.

WRX Brake Swap – increase braking power with 2pot calipers and larger, 11.5” diameter rotors from the Impreza WRX

Outback H6 Rear Brake Swap - Note: OEM 05-09 LGT Rotors are ventilated and wider, providing an extra boost to this upgrade (290x10mm vs 290x18mm)

great list man, I would like to help add some stuff such as sterring wheel selection and to add/change the seating, wrx changed its seats for the 04-09 models, they look just like the sti ones but they are all black same direct bolt on like all the other subaru seats. I will have these installed next week and I can take a picture for you.

 

Can you make a Steering wheel section as people would might like to upgrade to wrx steering wheels or sti steering wheels or even the jdm steering wheel if u can find the clock spring for it.

Great job bro!! All those strut tower braces fit? I will need to change my rear strut mount studs to longer ones. I have the 3/8 spacers on there. I thought I was looking at 100 each for those bars!!! You are the man dude! Edited by 98quiksilvergt

I gotta find someone who will make a cold air intake for me. As far as exhaust im definately getting those hi flow cats and borla replica headers. Really gotta make that boxer engine rumble

 

Cosmoracing.com has cold air intakes for our cars. you might have fitment issues from what i heard on this board though.

Ok now im a little confused, and am not sure which to buy. There are so many companies that are making the same thing, just not sure which to go with. For instance, crossmember bushing, some made by kartboy,AVO,TiC. Same with the rear diff outterrigger bushings, Whiteline,KArtboy etc.. Shifter bushings, kartboy,perrin,rallitek,cusco etcc....Now which are better, or do some just not fit our cars?

Personally I prefer a company that’s US based and makes everything so I would opt for Kartboy or Whiteline. Cusco is never in stock and it’s pricey. Perrin isn't bad but they don’t make everything and I am not a fan of the red. Whitleine is great, they make almost everything (not a fan of the Yellow though).

Most Impreza/ WRX stuff will work on our cars. Some may be legacy specific but I have 90% WRX/STi parts for my engine/ drivetrain so I doubt it. I am also a fan of Whiteline because they make a race and comfort line so it’s nice.
