Default Any Mods Remaining?

Hey Guys,

Must start off by saying that Nasioc.com has been my ultimate resource in modding my daily driver 2.5i to a nice small fun car to drive. I've had plenty of help and suggestions that i greatly appreciate. Mods ive done so far are

Engine:
-Willity Hybrid Intake
-Avg performance air filter
-Stromung catback
-93 octane tune by Phat Botti tuning
-Transmission cooler

Must say a significant performance increase. Engine has also been maintained with mobil 1 synthetic oil since day and spark plug change every 30k miles as well as purolater oil filter. Engine rides like a charm

Electrical and Audio

-Paranoid Fabrication Upgrade grounding kit
-Paranoid Fabrication "Big 3 upgrade"
-Alpine cda 9800 (think thats the model number) with tuning kit
-4 Polk 6.5 Dba 650 speakers 60 watts rms 91 db sensitivity
-12" kenwood sub forgot the specs
-Bazooka ela 500.1 monoblock amp
-blaupunkt pca 250 4 channel amp 60 watts rms per channel
-Completely changed interior to blue



Sound is nothing crazy, but definately loud and clear, windows go up quite fast with the grounding kit, and i feel its definately a smoother ride perhaps a hp or 2 gain no hesitation.

Suspension:

-20mm rear sway bar
-kyb gr2 wrx struts
-stock sti springs

Exterior:
-Added wrx spoiler
-sti bbs gold rims
-rally armor mud flaps
-wrx hood scoop (i love the looks although no purpose)
-NX beam 8000k HID
-led fog lights




Must say happy with all the mods, was curious any other engine mod we can add to the list that are affordable and worthy...

I know theres, headers, hi-flow cat, pulleys, but car is loud enough as it is really would change headers to unequal but not worth it to me, and pulleys in an automatic arent really worth it so ive heard...

Any suggestions or comments or questions please or any additional pics feel free to ask, thanks guys

There's ALWAYS something you can upgrade I guess in your case it depends on what you think is "affordable and worthy". As always, the best answer will take into consideration what you want to use the car for and how much your budget is, which you haven't told us yet.

Sorry for not supplying that, um I guess either beneficial engine upgrades perhaps some power gaining. Well I have 300 to spend as of now but I could save but it's very gradual.

I say go for a set of headers. The borla knockoffs on ebay seem to do pretty well for the price. You'll probably pick up a couple HP and some more boxer rumble!

I agree go with the headers...actual borla you can get around 350$ (check out boxer4racing) (I hear the ebay ones cause problematic oil changes cause they are so close to the filter.) Save for them and also go catless midpipe or high flow cat. Really does make a difference. I was full headerback catless exhaust on my 02rs and I loved it. Although it was a bit loud...it had the boxer rumble and sounded like a modified wrx.

unequal. It shouldn't be too loud...you might see slight performance gains but also a slight louder sound...but not overly loud. My buddy has an 07 2.5i with headers, high flow cat and catback and its not loud in the car while driving, it just sounds good and is only really loud when he gets on it...sorry kinda hard to explain but hope this helps. long story short it shouldn't be too loud. you should be good to go.

When you got tuned, did they tune your drive-by-wire system as well? I hear that there is a lot to be gained there.

I'd look into the exhaust, lightweight pulley, and cams. They each have their costs/benefits. I think you'd notice the biggest difference with cams, but you'd have to save up more money. I've never tried a lightweight pulley, but some people like them on automatics. I did an upgraded exhaust and didn't notice a difference really, but some people do. Those are the 3 (well, 4 if you didn't get your DBW tuned) that I'd say are worth researching a bit more.

I believe the tune included the drive by wire component, yeah I saw cams but 650 but if I send my stock ones I get 400 off.. But I heard install is expensive... Yeah same lightweight pulley I heard some mixed reviews...it's only 119.00 so it's not that bad

Yeah, install may be expensive, but I thought it would be a good one to add to the list of things to look into.

If you don't like the lightweight pulley, you could always sell it and get a chunk of the money back.

Very good point and I appreciate the suggestions, I wonder if the pulley install is difficult or expensive

the crank pulley is an easy upgrade and drops 4lbs of rotating mass (the perrin website has a video on it). However you should stay with a stock clutch and flywheel if you go that route.

See that's the thing I've heard the lightweight crank pulley is good but is a pain in the ass on a automatic which is what I have =(

It's not that hard. Grab a breaker bar and shove a big screwdriver in one of the holes in the flex plate. The hardest part is dealing with the inspection plug on the transmission. Of course if you actually remove the stuff that's above it, you will probably have an easier time.

Errr.. I'm assuming they still have a flex plate inspection cover on the new ones.

Anyway, just don't put it on expecting to be able to feel anything different.

If you want something significant I'd go with cams if you're ok with doing them/getting them done. If you're not having someone else install them though, you're quickly moving out of the bolt-on territory.

Installing a lw pulley on an automatic is silly. Save your money for cams or buy a FSB or some motor/tranny mounts. Shouldn't be too expensive.


Best advice: Lose the LED "fog lights" to save weight.














lol wut?

Make sure you have a mean security system to go along with that.

TWE headers if you want power gains, Borla headers if you just want sound.

Cams and a new tune for them would be another thing.

A further step may be switching to E85, if you're willing and feel like you can get it on a regular basis, just injectors, fuel pump, and tune.

I would also step to lightening the car, upgrading the suspension more, going more aggressive on alignment, better tires, etc. Power makes it get up to speed fast, but competent suspension and grip lets you stay fast.

What he said...I know several people that have put lightweight pulleys on their 2.5i's and N/A Saabs, and they all say that it was a worthless mod. They couldn't feel any difference at all...They have even offered to trade their lightweight pulleys for my stock ones. Heck, if you want to save 4lbs, clean out your car. It's alot cheaper.

Headers are an iffy thing in my book. Of course I ran into numerous issues with my install. It's also going to cost more than just the price of the headers. You have to buy a cat or a track pipe, and get it plumbed in by an exhaust shop...not to mention o2 extenders and if something breaks...like a head stud. So add another $250-$350 onto the price of the headers. Also, headers will move your powerband to the right. I immediately noticed the loss of low end power after my header install...although I have great power at highway speeds now.

Cams will definitely net you the most bang for the buck out of all of them. They will net you somewhere along the lines of 15-20whp, but again, it shifts your powerband to the right. If you're ok with having to rev to 4,000rpms to get the same power you made at 3,000rpms before the cams then go for it.

Have you thought about phenolic spacers?

Not all cams. Some cams move power to the "left".

Once those struts wear out:
Tokico D-specs and RCE Yellows, and a 22mm Front Swaybar

Because this isn't the suspension forum, I won't go into details as to why this is a better idea.

And cams.

Can anyone tell me exactly why a LW flywheel doesn't do anything on 4EATs? Rotational mass is rotational mass...
