slmgringo Posted April 27, 2008 Posted April 27, 2008 Soo, I'm curious of a rough budget and parts I would possibly need to get 200 HP out of my stock 02 Legacy gtl. I would like to not sacrifice much mpg if i can help it (tho from the research ive started so far performance sacrifices fuel economy). Im a newb when it comes to cars so just post up some ideas, and ill start researching. I want to learn, but just want a starting point, thanks, Brandon.
KnifeyMcShanker Posted April 28, 2008 Posted April 28, 2008 To be honest, you're probably not going to get 200 at the crank on a budget. That would require some engine internals modification and not just stuff you add on. You can get a short ram / cold air intake and a better exhaust system. It's not going to do a huge amount in terms of HP, but it'll make your car sound great and you'll feel a difference. That's what I did and I'd recommend it. Those two mods will actually get you a better mpg if I'm not mistaken. From there things get expensive for HP increases. You can go for cams next, I saw a STi set for sale in sl-i.net a few days ago for a reasonable price. That'll have a negative impact on mpg. There's a bunch of other things, that's just what came to me offhand, I'm sure you'll get a few different opinions here.
slmgringo Posted April 28, 2008 Author Posted April 28, 2008 cool thanks for the reply. From what ive read it seems like most NA owners opt for suspension mods rather than power (after exhaust and CAI). how much did your CAI and exhaust run you? Did you have it tuned, if so how much does it cost to have it done?
SLegacy99 Posted April 28, 2008 Posted April 28, 2008 As I recall my brother had about 180 comin outta his Impreza with an air intake and exhaust settup. He also had a lightweight carbon fiber hood.
Irrational Exuberance Posted April 28, 2008 Posted April 28, 2008 As I recall my brother had about 180 comin outta his Impreza with an air intake and exhaust settup. He also had a lightweight carbon fiber hood. how many hp from that?

slmgringo Posted April 28, 2008 Author Posted April 28, 2008 well guys, my minds made up. I just put in my order for some NOS. My friend with a civic swap said if i get a shot of NOS ill be able to keep up with him, should be here ina day or 2. Thanks again! Brandon ps yes..im jk.
whitetiger Posted April 28, 2008 Posted April 28, 2008 Let us know how quickly you blow up your engine. bet way to get over 200hp NA without an engine swap is inake exhaust and cams with a good tune. The tune being the key element.
Sarra Posted April 29, 2008 Posted April 29, 2008 You could run a constant 10 shot of nitrous if you're careful. Ummm... Intake, cams, exhaust, and EM are the key to 200 WHP NA. If you go Nitrous, you're no longer NA. If you want a quicker car, and have some cash, buy a set of Cusco front and rear diffs, but get them in 4.444 final drive, instead of the 4.111 you currently have. Believe me, a shorter final drive is noticeable, I had a BE with 3.9's and the difference to a 4.111 is astounding.
whitetiger Posted April 29, 2008 Posted April 29, 2008 rigt but a different gear rations wont increase engine power.
KnifeyMcShanker Posted April 30, 2008 Posted April 30, 2008 If you're looking for a long lasting engine, stay away from nos... My Short Ram was like $85 from cosmo racing. Dunno how much the exhaust was, came with the car from previous owner, but it's 2.75" from cat to a magnaflow muffler, sounds pretty.
whitetiger Posted April 30, 2008 Posted April 30, 2008 No, but it will increase th epower at the wheels. No, it increases torque at the wheels at the expense of top speed in each gear.
Long Island Legacy Posted April 30, 2008 Posted April 30, 2008 Do yourself a favor and dont mod an older legacy. If you want more speed gut the freakin thing. see if you could shave 100 lb/s for free that will deff make you faster. other then that say away from nos, its looks cheap and easy but wait till your motor blows and your out an entire car. Then the money you spend on fixing it if its even worth it will be outrageous.
Sarra Posted April 30, 2008 Posted April 30, 2008 No, it increases torque at the wheels at the expense of top speed in each gear. How often are you going to go 150 mph? I got a 2000 Legacy L to go that fast, believe me, it takes a long steep hill to get going that fast. I'm planning on converting to 4.444 FD in my BK6.
whitetiger Posted April 30, 2008 Posted April 30, 2008 I said top speed in each gear. If you are used to going 30mph at redline in 1st, well you wont be after the gear change. generally changing gears isnt the greatest idea because you affect your cruise rpm in 5th gear. you may be cruising at 60mph and the rpms will be over 3000rpm.
Sarra Posted April 30, 2008 Posted April 30, 2008 Going from a 4.111 to a 4.444 will cause me to run at 3,000 at 65 mph, as opposed to 2,750 rpm. I cruise at 60 on the freeway, so this wouldn't be an issue for me. 4.444's won't cause much of a difference at the top speed of each gear either, first will top out at 30 instead of 33, second will top out at 50, third at 75, fourth at 100, and fifth at 135. BTW, since horsepower is derived from torque, you cannot change the amount of torque without changing horsepower.
slmgringo Posted April 30, 2008 Author Posted April 30, 2008 Sup everyone. Thanks for all the replies. First of all, this Legacy is my daily driver and what not..i was strictly JK about the NOS shot:-p. On another note, Ive been researching some intakes...Cobb seems to be the name of choice but damn the setup i found is 300USD after shipping ( http://www.subaruparts.com/catalog/?section=867#2810 )..would i just be buying the name or what? Also, when it comes to cars, I'm pretty much a newb, however I would like to be more involved w/ this car...so would it be a stretch to try to install an intake myself? Interesting point about some weight reduction. What could i scarp to loose 100lbs? I mean the extra weight on the BE's had to come from something :-p. On the flip side though, I dont mind having a slow car if it means i have to keep in my back seats, trim, etc :-p (I cant rice out such a nice interior) Also, my 02 is coming up on the 30k mark. Again would it be a stretch to change my own transfluid or should i have it done @ the dealership? I didnt see it done on the dealership inspection reciete or another option "if its not broke dont fix it" Though this thread was initially started to get some information on possible power (thanks again for the info), i think i want to know more about getting better mpg. From what ive read, intake and exhaust, as well as grandma driving will help increase the mpg..anything else? the weight reduction? car lower to the ground? I used to run mobile 1 syn in my 95 Grand AM and from what i understand better oil can help fuel economy as well (though we wont get into the M1 debate here, as ive found some through the search) I think thats all the questions I've got for now, thanks again, brandon. PS I appreciate you also not flammin a newb :-p
Sarra Posted May 1, 2008 Posted May 1, 2008 I know what you mean about interior, I keep persuading myself not to tear the interior out of my BK because it's in such good condition. Get light weight wheels, that's one of the best weight reduction mods you can do.
deadlydave Posted May 5, 2008 Posted May 5, 2008 A lot of the weight of the BE's comes from a stiffer chassis (more metal) and a different rear suspension than earlier legacies. If you're dead serious about dropping some pounds, remove the sunroof and electric motor and have a metal panel welded in. Replace the seats with lighter ones. Replace all exhaust components with lighter after-market ones. Light wheels, aluminum brake calipers. Taking off stuff is the cheapest way, but there's only so much you can remove before you take a nice legacy and make it not-so-nice.

Any opinions on the Cobb Intake? Just seems like alot of money. Has anyone made their own from aluminum piping, etc?

I figure its gona be exhaust and CAI for me..and that should hold me over for a while. This Legacy stock already is faster than my old car was stock, and already more fun to drive. These mods should be good for now, as well as some new wheels n tires .
Svenerachi Posted May 10, 2008 Posted May 10, 2008 Cobb is expensive, IMO you're paying for the name and I know i'm going to get flamed hard for this, but screw you all its the truth. If done correctly and not skimped, nitrous oxide is a perfectly viable option for upgrading our engines, you just can't be a moron and drive around with the nitrous going 24/7 I've got a 1999 LGT 4EAT and have had an 85 wet nitrous system for the last 50K miles atleast. I've got an SAFC2, PLX WB02 sensor and guage, 1 step colder spark plugs, a dyno tune, msd rpm window switch, NOS-brand WOT switch, msd tach driver, etc etc etc.... my car has 189,466 miles, I just walked outside to double check, thought I might have crossed that 190K mark, but not yet. bottle is not hooked up at the moment(since last oil change), had an issue with the fuel line connector forming a super slow leak and didn't want to chance it, gotten busy with graduating college and now looking at drivetrain swaps after student loan money comes in so, let the flaming begin.... oh, and to kick it off, I was told via my tuner that every knowledgable subaru tuner said that my engine would grenade after 5K miles on the 35 shot.... and one last point, my engine runs better now that Ive been running the nitrous than it did before without, must have cleaned out some carbon deposits or else its just getting fast the closer to its death it comes
Svenerachi Posted May 10, 2008 Posted May 10, 2008 as for cheap upgrades, my custom Cold-Air Intake (CAI- replacing torque box with a larger diameter metal tube, bore out the stock intake box, remove snorkus and replace stock filter with K&N panel filter) was 75 dollars total (I installed, very easy in 2 hours taking my time and drinking) my Cat-Back Exhaust (CBE) was 250 dollars for mandrel bent 2.25in tubing connected to a magnaflow muffler(60 series maybe?) also cheap upgrades are lightweight crank pulley, makes engine rev a lil easier, reduces rotational mass of the engine, might make +1-2mpg best mpg increaser was the SAFC2 for me, allowed me to lean out my AFR and gave me alot of power that running rich was robbing me of
