Default Mods? What else while I am there

Unabomber and all,

Thanks for the post. I love it. I have worshiped Subies at a distance for ages and since late December I now have one. A seized 04 wagon. I just got the motor out and its off to the shop this Saturday. I will discover how bad the motor is. I have an up pipe and a 3in S/S exhaust (I hope its not too loud)
I am on a tight budget .... 2.0 stock rebuild, but while I am here what would be money well spent. If it was a Porsche 911sc you replace the oil pressure switch because its $15 and 10 hours labor, but now the motor is out its cheap prevention. With Subie's what a good idea? By this I mean all round. I obviously do the clutch and brakes. Do I go killer Bee and a 2.5 sump(is it worth it?) Anything else? The car isn't running so one more week isn't going to change anything. I am looking for what's wise long term. I am putting in a brand new motor after all.

Sorry for the long post.(noob)

Is there a faq for the next level or stage 2 upgrades?

Stage 2 is simply adding a downpipe with the correct tune. A few members have tried to start and continue a FAQ about Stage 2 and above.

So intercooler hoses, and an up-pipe are something that should be left alone for an 04 STi?
If someone could clarify that would be great

The biggest driver behind replacing the up pipe is to get rid of a catalytic converter, but the STI's and 06+ WRX's never had a cat in the up. Otherwise you'd upgrade your up pipe for an external wastegate.

Intercooler hoses wouldn't be a horrible, cheap mod, but if you're not having issues with yours then why bother.

Simply put, for first mods, I would do turbo back exhaust, short ram intake, Cobb stage 2, and maybe brake lines. You will notice a big difference there

Essentially. You'd have very little, if any gains for the money.

Question 3" Downpipe

I have a 12 STI Hatch and have wrapped some pipes and picked up a COBB Access port and have been very happy with it. I would like to start upgrading the exhaust to get to Stage 2. Is this possible to do in steps? What I am thinking is picking up a 3" downpipe for starters as it seems this is where a larger portion of the restriction is. Can this be done with effectiveness and could it get me to the stage 2 maps on my Access port? Any help is appreciated.

Thanks!

yes ^ with a 3" downpipe. you can use your stage 2 map. but i would recomend you also replace the stock muffler and other exhaust parts. do it once do it right. go with nvdia turboback exhaust setup. turbobacks is where no restriction occurs. slighty better than an catback setup. our stock uppipes (06 wrx+) still doesnt flow as good as a aftermarket uppipe so id suggest replacing that too. hope that helps a bit. do more research if you want answers!

A down pipe with the off the shelf tune will be real nice. Especially if your not looking to make too much noise. Your not going to really be able to tell a difference aside from the noise your car makes.( with a catback) There's a lot of stock subarus running around with a catback, making a lot if noise. not too many with just the downpipe and a tune, you'll put a lot of surprised looks on people faces (on closed roads, of course) As far as an up pipe, don't waste your money, your not moving that much air as it is and would be a complete waste of time money (labor) with a Cobb ots map. The stock catless Subaru up pipe will flow fine until you really start to make bigger power. And at that point, it's only beneficial to upgrade to a quality up pipe like grimmspeed or similar. I say find a used downpipe, flash the stage 2 map and enjoy. If you want to hear the boxer rumble, then find yourself a catback. I know it's not power related, but I always like replacing shifter bushings and even a short shifter if desired. It does not make the car any faster, but it is something that you touch every day and will make the car feel much better.
Good luck!

At first i had just a muffler replacement from nameless performance and it felt lacking. Sounded nice, but recently I had a shop finish the catback and its a great change. Sounds way better and I feel it gave me a little more oomph. If youre looking for off the bat power, sure a dp would be best. But my choice was to start from the tips

That's what makes modding anything great, individuals. I'm basically talking bang for buck.
Catback = car is louder (healthy Subaru motors sound like pure baby making)
Downpipe+tune= car is faster

Of course I am going to research this further, but this is what I was thinking. To be clear, I don't give a rats azz about the noise, other than I don't want to attract attention. So as close to stock as I can sound, the better. I am really just looking to get to that upper 300 hp/lbs-ft range without breaking the bank. Anyone else who has an opinion, I am all ears...personally I didn't think I would hear back same-day on a 7 -8 year old thread, you guys rock! Will definitely report back with results. BTW, stage 1 I am at 328 hp and 342 lbs-ft. Not quite enough for me, but enough to make you rexies cry...sorry, couldn't help it :P "I also have a NA 2001 Impreza RS, so I have done my time ". Really though, thanks a bunch and keep it comin'!

haha you must be new. 300 without breaking the bank. u gota pay to play. get a downpipe and full exhaust and a protune don't believe that dyno feature acesport tells u 348hp stage 1. on a real dyno it will probably read 200to the wheels.

You must be new at reading, I said 328Hp which is only a 23HP gain or just a shade under 5% above stock, so not exactly earth-shattering. And pay to play... Yeah, I am over 35K now, so easy there, my idea of not breaking the bank is probably a whole lot different than yours, hell the stereo, automatic start, car alarm and radar detector put me back more than $2,500.

and hudsonvalleybugeye, I did replace the shifter bushings and have been really happy with it. Just a very crisp feel and a super cheap upgrade.

Not to be a dick.... But. He did read correctly actually... To get a subraru running 300+ wheel horse power is pretty pricey. You car stock has roughly 190-220 wheel horsepower depending on elevation. Just bacause subaru says 300hp and your accessport says your magical 328 hp doesnt mean its true. Stay off a dyno if you dont want to shatter your believe in santa clause and horsepower.

Subaru estimates horse power at the crank. The access port estimates horse power at the crank. Adding a used downpipe to an existing ap that has an ots stage 2 map is "cheap" relatively speaking. This will put you in the "300 whp neighborhood". Different dyno's, altitudes, blah, blah, blah. Being a number chaser is where you will "break the bank"

i dont mean to be rude. but trus me. get a full turboback exhaust, fuel pump, new injectors (650cc+) and a good dyno tune . you will be near 300. then the fuel system leaves you enough room to do more upgrades like headers, tmic, turbo upgrade etc. once you start you cant stop
