a rod Posted October 12, 2009 Share Posted October 12, 2009 hey guys I am new to the site and was wondering if you could help me. I own a 1998 2.5 gt and was wondering what i could do to give it a little more. I was also wondering how to get rid of transmission lag. Any suggestions?

one bad bg Posted October 13, 2009 Share Posted October 13, 2009 ya. and i have high flows but not the ones i showed you and 2.5 inch pipe all the way to the muffler and took out the resonator cause, well, screw those things lol Link to comment Share on other sites More sharing options...
a rod Posted October 16, 2009 Author Share Posted October 16, 2009 Anything else I can do and what do you think about short ram intakes Link to comment Share on other sites More sharing options...
kaz98gt Posted October 16, 2009 Share Posted October 16, 2009 I've done some intake work with getting rid of the snorkle up in the engine bay. It's actually pretty cool when it all gets finished and it gives great throttle response and some noticeable torque. There's a page on another legacy forum that gives step-by-step instructions for rerouting the intake, but I don't remember the page now. If u find it, I threw a cold air intake down by the fog light I have yet to remove the airbox though Link to comment Share on other sites More sharing options...

a rod Posted October 17, 2009 Author Share Posted October 17, 2009 So did you pretty much make a ram air system. Link to comment Share on other sites More sharing options...

kaz98gt Posted October 22, 2009 Share Posted October 22, 2009 http://www.sl-i.net/FORUM/viewtopic.php?f=39&t=11765 here's the link to the page. what I ended up doing is instead of a fixed pipe running from the box to a mesh at the end, I threw a spectre cold air filter on the end down by the fog light. I'm working on getting the airbox out, because that's causing the most issues as far as flow goes. Then it's on to the torque box, and trying to re-rout the scoop to feed even more air into the engine Good luck! Link to comment Share on other sites More sharing options...
fatboy1214 Posted October 23, 2009 Share Posted October 23, 2009 how much did you pay for those borla headers i founds them for $160 shipped but i dont know about them cause its one of those things from ebay Link to comment Share on other sites More sharing options...
one bad bg Posted October 23, 2009 Share Posted October 23, 2009 if your asking me, it was about 180 for me on ebay Link to comment Share on other sites More sharing options...

one bad bg Posted October 23, 2009 Share Posted October 23, 2009 i have those headers, catco high flows, 2.5" pipe all the way back and a magnaflow, if you want to hear what is sounds like here it is. by the way i seafoamed it lol [ame=http://www.youtube.com/watch?v=teulvrddfmY]YouTube - Subaru legacy seafoam[/ame] Link to comment Share on other sites More sharing options...
rmb2485 Posted October 23, 2009 Share Posted October 23, 2009 I'd be interesting in hearing that exhaust without the Seafoam going through the intake. Care to make another short video? Also, if anyone else is thinking of using Seafoam you're supposed to keep the engine rpms elevated (3,000ish) while you pour it down the throttle body or suck it up through a vacuum hose, not rev the engine up and down like in the video. Water actually works just as well too; think of it as 'steam cleaning' your combustion chambers. Link to comment Share on other sites More sharing options...
one bad bg Posted October 23, 2009 Share Posted October 23, 2009 acually that after the seafoam went in and the car sat off to 5 to 10 mins, that was the start up to clear it all out.... and i could make another short vid for you but it sounds the same Link to comment Share on other sites More sharing options...

Can you make a video and hold the rpms up for a few seconds, rather than just revving it? Link to comment Share on other sites More sharing options...
one bad bg Posted October 23, 2009 Share Posted October 23, 2009 ya, its raining now but its not supposed to tommaro so ill do it then, and then it takes about a day to load on youtube, so sunday you should be able to hear it, and ill do a couple variations, and an in car for you Link to comment Share on other sites More sharing options...
a rod Posted October 24, 2009 Author Share Posted October 24, 2009 What gains should I expect from my 2.5 gt Link to comment Share on other sites More sharing options...
one bad bg Posted October 24, 2009 Share Posted October 24, 2009 on the butt dyno, not much of anything, if yours is auto then you wont notice anything performance wise. mines a 5speed and i noticed a little bit more torque in the lower rpm range, i don have to downshift so much to go up steep hills now. and on flat land it picks up a little quicker. but its not like its gonna shave a second or 2 off your quater time Link to comment Share on other sites More sharing options...
one bad bg Posted October 24, 2009 Share Posted October 24, 2009 Ah, ok. Can you make a video and hold the rpms up for a few seconds, rather than just revving it? wow. this is the quickest ive seen youtube upload a vid, took like 5 min, but anyway, ask and yee shal recieve. btw, the slight smoke is just a fuel system cleaner i have in the gas tank lol. kinda freaked me out when i watched the vid seeing as how my engine was just rebuilt but then i remembered that its prolly just crap in my injectors burning off, so here it is. i didnt do an in car but if you want that i can do that too. [ame=http://www.youtube.com/watch?v=5uQPSTn8xEA]YouTube - Borla headers on 98 legacy[/ame] EDIT: thats with borla headers, catco high flows, 2.5 inch pipe straight back, and a magnaflow. if you keep the stock midpipe, the only difference will be it wont be as deep of a rumble.

kaz98gt Posted October 25, 2009 Share Posted October 25, 2009 that's sweet! I'd want to try that for mine once I get some cash haha Link to comment Share on other sites More sharing options...
scoobydoobie Posted October 25, 2009 Share Posted October 25, 2009 I had a similar setup on my 99' SF. Borla replica header-> Stromung HFC pipe-> Stromung catback. It sounded awesome and definitely gained a bit of HP/TQ and throttle response. Better mpg as well. Had some delta cams out of an 05' RS to go on, but ended up selling the car and getting the LGT. Anyways here's a couple clips of the set up: [ame=http://www.youtube.com/watch?v=yS_K2qHl6lU]YouTube - 99 Forester exhaust clip[/ame] [ame=http://www.youtube.com/watch?v=NfibIenOu5g&feature=channel]YouTube - 99 forester exhaust clip 2[/ame] Link to comment Share on other sites More sharing options...
lunatech Posted October 29, 2009 Share Posted October 29, 2009 As far as transmission lag, I've read that this works on 1st gen leggys, however I don't know if it is the same for 2nd gen. http://www.alcyone.org.uk/ssm/powermode.html I hope this helps.
