Post New 2003 WRX. What are the best mods for daily driver and fun for the buck

Just got my 03 WRX Yellow (the Dealer customed order the front side and rear ground effects) so hopefully their won't be another yellow one with the factory effects. I ordered a cold air intake and was wondering what are some of the mods out their that work and wont kill the car in a year.

I've had my yellow 03 for about 2 months now and really love it. I'd like to see pix of yours with the ground effects on it.

As for best mods, catless uppipe and downpipe. I went with the TurboXS stealthback and it really freed the turbo up. I'm still waiting for my uppipe to be delivered. It's really important to get that cat out from in front of the turbo before you do much in the way of mods.

Do a search for the "3/16 mod". It makes a difference in how fast the turbo spools up.

Oh, a factory or Kartboy short shifter with the Kartboy bushings is an excellent addition, too.

The cold air intake is not really a good bang for the buck on these cars. The most you'll get is a lot more noise and the cool looks.

I have seen a few (at least two) Sonic Yellow with the factory ground effects. There is an i-clubber from Puerto Rico with them, an STI grill, and an STI hood scoop. They do look great. I only have my sides painted. As far as bang for your buck mods for a daily driver: I am on my second WRX and put over 42,000 miles on my first one before trading it in. For 100% reliability, go with either a good turbo or cat back and an STI shifter. Unless you race your car, either auto-X or drag race it at the track, I don't think there is much more you need (assuming you have ugraded wheels and tires).

I am using my 02 WRX as a daily driver... and i have to say that IMO tire upgrades are key... i think soa just didn't put on the right rubber. I would include new tires in any power mods you make.

Best overall mod is wheels and tires. Best bang for the buck is the 3/16 connector.

best mods for daily driver and fun for the buck. Go directly to suspension brakes wheels and tires forum. Do tires, do suspension, do brakes and then come back here, IMHO.

Get some good tires and suspension mods first. The car has
enough power to get you into trouble because the stock
tires suck arse. Also, go do some autocrossing, you'll really
learn alot about your car and it's limits.

I have an MR2 with full suspension, and I have WAY more
fun driving it than my WRX thay has a lot more power.

yeah, suspension is great... for me I needed a lil more power, but luckily the intake and axel back has satisfied me for now. i have my aerodynamics done and i'm just waiting on some suspension items sitting at the docks... then I need some rims and tires eventually/ at least tires. (the way i drive it shouldnt take long )

my last car was an integra, which is traction limited, but has more power than this car and handled better. the WRX can easily be a 12 sec car and still handle GREAT. it comes down to driver skill really. Learn how to drive and control your car at the limits and you'll be fine.

And if you have no worries about removing catalytic converters from your car, then throw on a turbo-back to compliment the intake and you will have PLENTY of power to play with. Just make sure that you know how to drive before you go crazy with it.

Also is the stock turbo gauge ok. It came from the dealer with a turbo gauge on the steering colum. Or should I ad a boost gauge or are they the same. Sorry first time for a turbo for me. Had a Z-28 before. I have upgraded my tires and rims to aluminum 17inch rims and Bridgestone Potenza RE011 215/45/R17.

I will post some pictures in two weeks win the tint and ground effects are done.

I really liked the 3/16 connector. Some people were getting boost spikes. I only spiked about .005Mpa.

I use to have a WRX :(

Thumbs up

Well I was on a budget and this is what I did.

Kart-Boy shifter and bushings $135
Amsoil airfilter,Snorkle remove,Summit velocity stack $55
Pro-Drive Axle back $385
Grounding mod $free
Instead of 3/16 fitting I replaced the whole hose to 3/16 hose$4
Boost Monkey set at 16psi $119
Autometer 2" gauge $free (got it from my buddy)
Full synthetics $100

I want to get some SSR wheels and some Mich Pilot A/S but I`m remodling my kitchen and want to build a garage So they`ll have to wait.

All I can say is the car screws and I really dont have big bucks into it.

Bill

Default Vishnu stage two (2) - in progress!

Hello:
I love this car (WRX, 2003 Sonic Yellow)!

This is my second WRX, since I gave my son the first, a midnight pearl (black) 2202 WRX (in college in Colorado).
Anyway, I did some factory mods to the previous car like- wheels/tires (SSR comps & Dunlop 9000's), STI suspension and factory ground effects, factory guage pack, STI exhaust muffler. MOMO air leather shifter, etc. Great car! Enjoyed it very much...
I enjoyed the car sooooo much that I had had post-partum (separation) depression ("blues"...and, bought a new 2003 WRX for myself!
I am now awaiting install-completion of Vishnu stage two (2) performance by Vishnu tuning in Pleasanton, CA. Shiv and Brett have been informative and quite helpful in coordinating this major project: (925-924-9800):

Vishnu Stage two (2) package includes ("not for the faint of heart";Note: I can't even imagine stage three (3)):

VF-30 Turbo
STI 530 cc injectors (I didn't get fuel rails)
Unichip ECU w/ custom program
Pulley kit
MBC
3" turbo back exhaust w/ dual tip muffler (I want to go incognito)
EMI harness
Defi guage surround and guage (to be determined, mayve HKS-water temp, fuel pressure, egt)-(I already have STI turbo guage)
321 Up pipe w/ new gaskets
Walboro fuel pump
NGK (cold) spark plugs

*plus (+) engine tuning/management by Shiv on an All wheel dyno (can't put a price on this, in my opinion!)...

I also opened my ($) wallet for: top mount Intercooler with STI under tray & Silicone hose kit, Stoptech front brake kit and rear lines with hawk HP pads, DMS Gold coilovers 40mm suspension, front STI top and rear top mounts, Cusco rear sway bar, front and rear aluminum lower control arms, MRT front strut (tower) brace ("yellow" matches Sonic Yellow color, more or less)...then, antracite SSR comps 17 X 7.5" wheels and S03 Pole position tires (225/45/17), and finally, short throw shifter bushings (factory installed short throw shifter), and greddy turbo timer (to be installed in ashtray area?). I have a MOMO shifter on already yellow and black leather (matches MOMO steering wheel appearance).
Vishnu is providing a (Vishnu) battery tie down...4 wheel alighnment and suspension tuning, test drive...Alot of labor costs...
The Boost will supposedly be kept to about 15-16, or so (to be determined-this will, after all, be my daily driver!). I asked about the following, for instance, but did NOT have recommended--> an intercooler spray kit, cold air intake (CAI) or removal of silencer, or blow off valve (BOV)-the arguments against seemed valid, cogent explanations as to why they either wouldn't contribute anything (substantially) to the performance of the above package, and/or might even be detrimental to reliability!
I hope this helps some of you out there...I wasn't on a specific budget so was able to do this! I have a firm belief that lots of exertise, experience and competence resides at Vishnu Performance and entrusted them with my "baby".
You might consider staging your mods, but they certainly should be progressive and integrated in some manner and in the hands of an expert tuner with engine management experience!
Did I say that I love this car!

Updates/More to follow...

Default Stock tranny and clutch

I looked at the Vishnu stage two but think I will wait for stage 3 or cobb tuning RT spec
I am worried about the stock tranny and clutch. I have read horror stories about the tranny not holding all of the HP are there any beefy aftermarket combos available? or any ideas to rebuild a stronger one?

If you're on a budget get an up-pipe and a manual boost controller. Best bang for the buck right there.

Add a downpipe down the line, maybe even a txs stealthback.

Yeah, the 2003 yellow is not that rare. Red might be more rare.

Yes, it's the same thing. I find the stock one OK except that the needle is very hard to see at night.


Will my car still pass inspection if I take out the pre-turbo cat? I'm in DC which I don't think requires California emission standards.
