Default Need help with new 2011 2.5i impreza, N/A

I have recently become the proud owner of a new 2011 2.5i Impreza. It is N/A and i've been having a hard time finding out good information for a starting point as far as mods go. I've done some searching and have been fairly unsuccesful. I know since my car is N/A that makes things a little bit more difficult. I'm not very knowledgable about the mechanics of a car, but I am a quick learner. My ultimate goal with this car is to one day have a turbo in it, along with all the necessary parts for the car to run safely. Although that could take some time. I've heard that I should start with a catback or a CAI, but seeing as I live in CO a short ram would be more practical. Any and all information would be great, and thank you in advance. Even if it's just a link to some other information, it would be very appreciated. Like I said, i'm new to this world, but i've been in love with subaru ever since I first test drove one at 16 (sadly the family went with a honda instead), but now that I own the car of my dreams, I want it to run like one too.
thank you again in advance

Well let me tell you what I've learned....
Move some investments around, you will need money.

Our engines stock can handle about 7lbs. Safely.. stock (the numbers are somewhere around their... I may be incorrect)
you engine will get about 75000 miles off of that

If you want to go engine-able turbo mods.
Get ready to shell out close to 10-12 g's in just parts.
Look at places like rallitek.com very thorough

Also our engines are not honda's they are extremely bratty when it comes to mods... get ready to tune the **** out of your car (my suggestion.. wait till warranty expires, obtain ALL parts, and then install and tune)

Basically it all comes down to how much you're willing to shell out on a brand new car....

Go to rallitek.com

And browse the suspension parts they have
Sway bars
Bushings
Mount
Strut tower bars
Those won't give you hella improved power, but it will allow you to have a tighter feeling car

Look at some things as well like,
Lightned pulleys and such

And a lot of the diy mods, you can make your car look nice without spending a lot.... spend some time here, it will help you in the long run

You should search and look at a lot of the stick faq posts... so much great info... look for the username of unibomber... he's a great asset to the community

Also learn to take everything with a grain of salt... the natives get restless

And like all the other nasiocer's will say....
Shoulda bought a wrx lol

Haha good luck and good hunting, remember, we are all in this together

I've looked through the sticky posts and things like unibomber but most of the stuff is pertaining to the WRX or STI. yea I know I should have gotten one, but I couldn't get a loan and had no one to cosign (blah blah blah, right?), and I really wanted the car. Like I said though, couldn't be happier with it anyway
I went with the 5mt
thank you for all your help

It's basically pointless to turbocharge a car which has a factory supported turbo model.

Moreover, power mods on an N/A subaru motor (especially the newer ones in 2.5i models) are pretty much entirely worthless.

You couldn't get a loan because nobody in their right mind would offer a loan to a high risk applicant for a purchase with no ROI. Just throwing that out there.

No problem. Lol I was just saying what I'm sure everyone would have said

Lol and don't explain yourself... I had 9 g's I put down ( I wanted a new car that I wouldn't have to worry about any major maintenace for a while) I coulda gotten a wrx or sti. They want 710 for 0% I had 701 , I begged my dad to cosign to get the rate, and he eventually agreed lol

Also insurance is balls expensive already so having a turbo car when I was under 25 was just not in the cards!

I love my 2.5I though.

And I like you know very little about cars, but I figure this car is great to begin to learn and study how things work and get a great understanding to cars, so when one does buy a wrx or better, you have your **** together lol.

You don't have to be a dick about it. Just throwing that out there.

That was kind of harsh man. no one but the owner knows what situation one is in when they go for a loan...

Maybe people don't have credit, maybe people don't have good credit, maybe someone went through a divorce, maybe someone got sued for something, you never know. Keep those sort of comments in your head.

Believe it or not some people take offense to personal matters like that, for some people its also embarassing

General consensus: Stick to suspension. Engine isn't worth spending a cent in mods. Do general preventative maintenance, take care of it, and upgrade the suspension/tires so it'll be fun to drive. No one needs a 265 HP car when they're so young. NO one.

Sorry, wasn't trying to be a dick. But the "blah blah blah" comment made the OP sound pretty whiny, so we're even.

Anyway; if you had to get it cosigned you're a bad risk. Doesn't matter why. More importantly, a car that is anything more than just something needed to get to work has no ROI (unless you can show them a business plan...), so the bank is going to be very, very timid when somebody asks for a loan to buy one. Taking a giant loan out on a car is a pretty bad idea anyway.

Furthermore, I forgot this is the newbie section.





Back to the point though, engine mods are still pointless on his motor. Leave it stock, enjoy full warranty coverage should something go wrong, and play with the suspension to make it handle well.

dont turbo it unless you rebuild the engine with low compression pistons, dont do the short ram because the resonance will make the maf read a **** ton of air coming through when its not and make the car run uber rich, unibomber i believe has a faq on this, and from what ive read from this forum is if you have a 2.5i just do suspension

like everybody else has said so far, sticking to the suspension is going to be the best use of your money.

but there are a few others things that can do to really "awaken" your N/A without braking the bank, i.e cams and messing with internals to boost compression. now, doing a CAI, exhaust and tuning can help, but until you have a turbo system you won't be able to make enough power to really make them worth it.

first thing I would get is a light weight crank pulley and maybe lighter accessory pulleys too. if your car is a DD then I would probably stick with a stock diameter crank pulley.

then I would look into a light weight flywheel and maybe a little better clutch. don't get too much clutch or you will hate yourself later. check out Unabomber's FAQ on clutches. I learned a lot from him.

and last but not least, a short-throw shifter can add a lot more enjoyability too.

and then mod the hell out of the suspension. (coilovers, swaybars, end-links, etc.)

I did these things on my 98 N/A impreza, and although I didn't really gain more (if any) power, it sure made the power more available and noticeable. I plan to do some of the same things on my new 2011 impreza too.

hope this helps and welcome to the cult.

I know you said your ultimate goal is to add turbo, but what is your goal for the car overall? Most people have the endgame in their head based on what that car is to them: daily driver, weekend whip, track day, rally cross etc. Sometimes the answer to that question determines where you should spend your money or save your cash. Judging on your OP, its your DD, and I would shy away from the turbo just from a reliability standpoint. Suspension and tires would be my first focus and you'd be surprised how much faster you'll feel you're going just by upgrading how the car grips the ground.

Wow it has been a long time since I've posted. To all (if any) who are interested, I have begun working on making this imp a bit more fun. Purchased a grimmspeed lightweight crank, cosmo racing CAI and an spt short throw shifter. Pics will come soon. The CAI isn't on yet more based on laziness than anything. The short throw was a fairly simple install and if course it was worth it. The crank pulley install took longer than expected but that was due to lack of research on my part. It has made (to me) a significant improvement in available power. Not anything ridiculous but I definitely see the revs climb and fall much more quickly. I've had a lot if help from these forums and thank you all for the input

Not worth your money to drop a turbo into a 2.5i. Do suspension and tires and enjoy what a 2.5i can do. It is what I am doing right now while I wait patiently for my chance to eventually own a wrx.

I scrapped the turbo idea a while ago. while it is possible, it would require to much effort and to much money. So I'm sticking to the basics

Like said above, I would stick with basic bolt on power adders, and put most attention to suspension, tires, wheels. Your friends will say its not fast, but throw the car into some turns and such after suspension tuning with them riding along I for one, think a grippy, suspension tuned car is more fun than a highway speeder. regardless of car brand/make/model.

everyone has their own opinion about different brands and such. First gotta know Whats your budget? Suspension thats cheap will generally ride pretty hard and can have problems. Thats like cxracing and megan and racelands. If you spend more, you get more with bilstein and k and w thats quality stuff but its prettty expensive. Most of these companies also make springs Are you looking to be herraflush or simply handle better? If your trying to dump it why not do bags? As for wheels once again its about the $$$ as well as your own personal choice Also have you done strut bars and bushings and sway bars yet?

I don't want to dump it just a nice height with no wheel gap. As of right now I want work cr Kai's. My boyfriend says they will be a waste of money because they aren't a great size to fit flush with my car. I don't want to spend a ridiculous amount of money but I'm willing to put a good amount in. I don't know how I feel about coils vs. springs tho. I'm looking into t tein and the ebachi springs. Haven't looked into coils too much. Haven't done strut bars or bushings yet. I do plan on doing sway bars tho. I wanted to trade for a wrx but right now it's not really an option so I just want to make some improvements style wise. I know there isn't really anything to do performance wise so.

eh in my opinion add some plasti dip drop it with cheap coils do an exhaust maybe a short shifter and call it a day baisically stuff you can trade to your wrx. Why spend money on something your gonna trade eventually just hold off.
