Default Performance on an Auto (gasp)

Well, I've been thinking pretty hard about what I want to do in terms of modifying my MY02 2.5 Impreza RS. It's....an....AUTO. <shudder>

I drive in traffic a lot, and I can't drive a stick (yet), and I need the better traction control of a 4EAT. I like the Automatic Tranny. My question is, is it worth trying to make my car a really fast AT car, or should I just save my money so I can buy a MT Impreza and mod that?

I just want to be able to do some Auto-X events and maybe enter some car shows.

Any advice would be greatly appreciated

There are alot of people on this board who put up good times with an auto, do a search, I am sure you will find tons of info. Plus, if you are looking for a show car, it doesn't matter if it is an auto or manual.

You aren't going to be racing it that much, so it won't really matter. If you already have the auto car, then just deal with it.

Granted you won't be as fast as the manual guys mod for mod, but it'll be fun anyway.

And in an autocross it won't really matter much because there won't be much shifting involved anyway (for my local races anyway).

Do a search for my "everyone give props to your 4EAT" thread in the tranny forum. several pages of people talking about the reasons they like their auto.

welcome. another automatic 2002 RS.

Well I recietly got a 16.8 at the race track. I will list my N/A mods.

Cobb N/A/Turbo cams
proECM chip
Tranny cooler
Cobb CAI

Stock quartermile times for these cars are around 18.2. so as you can tell. I shaved off a little time.

Now I believe if I had a full header back exaust I would have been able to shave a half second or more off my times because of the CAI and cams. The cams IMO need a full exaust to realy feel the true power they are making.

Don't feel like because you got an auto your screwed. if you end up going AFI, like myself. You will relise that you are ahead of the game in some aspects. (no worries on snapping the tranny till the 250-300hp mark).
I will not say I am anywhere near knowing anything subaru related. I just know what I have done and will be doing but if you would like to chat about the 2k2 2.5 4eat. Feel free to IM me on AIM or PM me on i-club.

good luck

i think iirc the tranni can handle more than 300HP....and as far as times go, i think you should be doing a bit better.....i have a udr pulley, stromung muffler/ custom mid, heat shielded cone filter on TB, NGK plugs, and well thats about it, i have a best time of 15.8, but i only did that once so i am not gonna say that is myt fastest time...my fastest consistent time is 16.2.....thats .6 secs off of yours, albeit the 2k2's are heavier i dont know that it would be THAT much.....

i think with some practive you should easily run quicker than that ...i love having an auto, plus when i beat people at the track or on the street and they ask" what do you got in there"...once word...."automatic" the look is classic....

so yes spend money and make the auto faster

good luck

NO PROBLEM WITH AUTOS IN AN AUTOCROSS...JUST LEAVE IT IN 3RD AND DRIVE..WE HAVE AN ADVANTAGE IN YOU CAN DRIVE TWO FOOTED (LEFT FOOT BRAKE) IT'S SO FUN! IT'S ALSO NICE IN THE CANYONS AS WELL. ALTHOUGH NOT ALWAYS IN 3RD.

ah, well that was my first run on a 90 degree day after 2 hours on the highway driving to the track with a 30 car subaru pack. So my fuild wasn't that cool. So my shifts were taking a little longer. BTW. are you gutted? Because I also had everything in my car. Even the Mc-d's bag from that morning. My cars quick for a CAI, Cams and stock "motor chokeing" exaust.

I run a 16.1 the last time I was at the strip, but I'm saying that my car could run a 15.5 or so.

All I got done is:

Full 3 in cat back with DynaMax 3 in straight through Race muffler
TCII
SFC-hyper R
Intake on throttle body
Polished Trhottle body
Rerouted coolant line around throttle body in stead of thorugh it

I also have reduced the weight of my car down to 2640 lbs instead of the stock 2900 lbs(both with full tanks of gas.)

I ran a 16.796 @81.09 last friday with my 4EAT. I definitely think I could run better, because it was incredibly hot and humid. I just have a Ganzflow, ProECM chip, and a lightened crank pulley.

DocterNick- You times do seem kind of slow, for what you have. Did you launch your car, or is that time from starting from idle?

my car is not gutted it was actually at about 1/2 tank and still stocked....ie spare, junk in da trunk...i always vary the launching techniques to see what works better....

vacculock the brakes, rev and launch...
dstraight dry lauch....
using D or 3 or "speed" shift......
neutral drops from 6K.......
plus sometimes my brother drives...he is 10lbs lighter

Andres
ust kidding of course about the neutral drop

Are torque converters available on all-wheel drive cars like the Subaru's?? As a Trans Am owner (M6), I can tell you that a TC can shave about 0.5 sec off a quarter mile.

Minor update on my project!

So far, I've done the following:

-> Ganzflow intake w/ K&N Filter
-> Stromung 2.25" Dual-tip SS muffler & SS midpipe
-> Switched over to synthetic motor oil (Mobil1)
-> Grounding mod

I notice a small increase in power down low, and some pretty significant gaints in the mid/high range (and it sounds like a beast). However, after doing some road tests, I've determined that my car lacks power in the high RPM range.

Any suggestions or recommendations on what I should do next, keeping in mind my 4EAT limitation?

Minor Edit:

Upon second thought, I decided that it would probably be helpful if I provided you all with more information about my goals and limitations. The object of my project is to gain about +25-40 WHP over stock while ensuring drivability and reliability. Cosmetically, I already know what I'm going to do (Lumar stealth tint all around, debadge, painted WRX sideskirts, & clear corners), but as for power, I don't know what will be the best bang for the buck at this point.

Financially, I'm not in very good shape. I just bent a control arm (!) in a minor accident involving a curb and snowy road conditions, so I have to pay for that. Otherwise, I'm a college student, and I make about $300/month, counting all the bills and expenses I have.

What would be my best bet for the next mod to do in a month or two?

I think your best bet is to save up for a turbo. The auto can handle the power of a turbo better than the manual so you have an advantage there. If turbo isn't something you want to do then you could always get a UDP, header, high flow cat. Then Cams would be your next step. In the long run you are going to spend more money if you go NA. 25 to 40 whp is going to be hard without forced induction.

The problem with a turbo is the automatic voiding of my warranty

I was thinking an item under $1k, like headers, cams, pulleys...?

4EAT limitations?
The 4EAT can handle more power than the 5spd
Spend some money at Level 10 and you'll shift just as fast or faster than a 5spd

My 4EAT makes a great auto-x car
I love stomping WRX's too

Ask Cobreth about trying to keep up with my auto in his 5spd RS

Well, I figure that Level10 work would cost $1k+, and that's outta my price range

Well, I'm thinking of doing one of two things when I get home in March:

1) ProECM (let's hope it works for me!).

2) Tranny Cooler & Flush/fill w/ Redline synthetic AT fluid.

This in addition to a pair of 6.5" JL XR-series components up front and a 4-channel amp install :P

Definitely ProECM chip & pulleys, then cams before headers...

Cool

Bone stock my baby ran a 16.7 and I haven't run it since, so maybe I should take it out to the track.
DrBoy do not waste your money on a chip, get a AFC and someone with a wideband o2 to tune it for you, or take it to a dyno, AT can goto any dyno.
The cooler with Synth Fluid will help with the shifting a bit. Definatly speed shift and break lock those help a ton too.
Pullies do not to anything but look cool, this is from someone who has them on his car.
