Default Improving an old Legacy Outback

I own a '99 Legacy Outback and have been looking for aftermarket parts with no avail. I am not looking to go crazy but I would like to pick up some speed and improve mpg. Everywhere I call only tells me they carry impreza parts or my car is too old. Are there any compatible parts out there? Or does anyone know a good site that carries some parts? Also any recommendations on where to start with the car would be great, currently the car is completely stock. Thanks for your help!!!

I'm sure everyone would agree with me on this that our older model n/a legacy's are not made to make power even with aftermarket parts unless you go forced induction or rebuild the motor from internal - this way would mean much more expense/investing. Suggestion is to work on footwork (suspension) coilover/struts springs/swaybar and most important tires! for better cornering. If you want a boxer rumble you should get borla or borla replica off ebay (UEL header - unequal length header). It would give you slight power in the midrange. OR you can do Equal length header which would give you more gain overall (Cobb, OBX, MRT, etc) but they are more expensive and the exhaust would sound mean but it would be less of a boxer rumble. Check youtube or the sound / video gallery in N/a forums and you will learn alot. You can also look into putting intake, Hi flow cat, catback (nothing larger than 2.5") But if you dont want CEL (check engine light) you have to be careful how you mod your car. As for catback most of us did custom catback through exhaust shops which cost much less and you can choose what type of muffler you would like to choose out of many types out there whether you want it loud (N1 style) or quiet (stock sti or something with bigger canister to muffle things out). Other suggestion would be to do a good grounding mod, do regular maintenance for sluggishness. And Weight reduction. Other than that...cosmetics JDM tails projector headlights rims. etc. Hope this helps...I'm sure I saved you from doing tons of research. Ask questions. Everyone in the LEGACY part of nasioc is friendly. If you go elsewhere...people might be slightly b*tchy telling you to use search button.

My favorite mod so far has been my lightened flywheel. I'm getting an equal length header next. That SHOULD be a good performance boost.

I'm sure you have figured out by now that most parts for the n/a impreza will also fit the n/a legacy. Some suspension parts will also fit.

cheap and easy..

lightweight pulleys will add a few hp's,
tranny mount - wont add hp but will make your car feel faster as it takes up that tranny slop.
intake will add a few more hp's
full exhaust will add a bit more hp's
get that baby tuned and flashed with a piggyback ecu (rallitek's perfect power)

that all will run ya about $1500-2000 and you might get about 30 more hp total.

that PP6 is an awesome flash... on my old leggy outback i got 6whp and almost 2mpg better due to the fact our cars run rich on the gas... that was $600 installed and tuned.

you've got an outback, so you already have the 20mm front sway and the 18mm rear sway (mine's an older L model, so i had to upgrade to the sways that came on your car stock). those are pretty good already, but if you want to upgrade, Whiteline makes adjustable ones that can be had for a couple hundred $. you will want to upgrade the endlinks too though, which will up the price by a bit. you could also just put the Whiteline endlinks onto your stock sways, getting rid of the wimpy rubber bushings.

for suspension, i would just get springs/shocks and top hats that are meant for a WRX or Sti and just swap them on. support for our cars isn't that great anymore since Eibach stopped making sport lines in our fitment, but WRX and '04 STi springs/shocks will bolt right in. both will drop your car quite a bit though, so mind your rear fenders, and the STi suspension can get quite bumpy (i love mine though).

JDM front strut braces can be had fairly cheaply when they show up, or you can use '93-'01 Impreza front strut bars, and '02-'07 Impreza rear strut bars. then just pick up some good used 16" rims ('02-'04 WRX rims always look sharp, and they're very common. most people also don't sell them for very much unless they've got some killer tires on them.) and then splurge on tires.

you can also check the pictures threads and see what people have done. there's plenty of us BG/BK owners here, and we're all willing to give some advice.

keep in mind that if you use stock wrx suspension bits (springs and struts) you will lower the car at least 1.75''. the outback sits already more than an inch higher than the "L's" and using wrx stuff drops the "L's" by about an inch.

oh man, please read the FAQ i wrote on that subject.. i will strongly advise against using wrx stuff on our wagons... if you really want to improve/lower the ride get some ground control coilover sleeves and matching springs for $400 and do it right the 1st time.

as for "tranny slop" hmmm,, you know when you step on the gas and rev to above 4k and then shift and you get that jolt as the power hits the tranny then to the driveline before it hits the diffs, well thats tranny slop. with a harder tranny mount it removes that jolty movement from the shift. hope that helps.. but its well worth the money and its an easy install.

I have a 98 LOB and the first thing I did was the snorkelectomy (remove intake snorkel from inner passenger fender) and an e bay intake for a 2.5 RS. don't know any true hp number gains but the butt dyno likes the improvement (really climbs above 3k rpms instead of bogging). Next mod is a ACT streetlite flywheel and Exedy clutch.
