Default Kob's 2004 WRX "Now SM" Build - 7/2/11 Lots of Updates

2004 Subaru WRX STX Build

Start Date: April 12, 2010
Updated: July 2, 2011

Plans: Supreme handling and a hoot on the street and track...

Background
So here we are, finally after being out of the car modding game for almost 2.5 years now, waiting for that perfect car to show up and I finally found it. On April 12, 2010 I picked up a 2004 Subaru WRX to setup as my fun daily/weekend car with a side of autocross and track in mind. The car as it sits right now is 100% stock and to my knowledge and how the car was use never really thrashed or abused, which for me was the selling point.

I should say at this point the WRX will mostly be prepared to compete in the STX or E-Street Prepared class of the SCCA Solo 2 program. It will probably receive a roll bar at some point as to be a little safer on the track and to be legal for hill climb action. Starting the build out I am not going to go too crazy, but would like to get the most out of the stock turbo as far as power is concerned. The car will be receiving a needed refresher first and foremost. From there we'll get it running tip top with some power adders and move on to a custom set of coilovers and some other little handling bits not yet disclosed.


Feel free at any point in the thread to pop a question or if you think I could benefit from something that you have a background in please let me know. I love criticism and it gives me motivation.


My Background
I also should throw a little about me in here as well, since I haven't been on here that much in the past you could say. I've been autocrossing since about 2004, I've won a few championships here and there along the way along with the 1 and only National Tour event I participated in. I started racing a 1993 Saturn SW2, which was setup for the at the time STS class, now ST. Bought a 1991 Honda Civic Si to run in STS in the winter of 2006 and ran it that season and swiftly sold it 8 months later to build a 1993 Saturn SC2 for STS. The Saturn was incredibly competitive and incredibly expensive to build, pretty much being that everything had to be custom made. It was a really fun project that I do not regret at all. Unfortunately it was still about a half second off a well prepped ST Civic Si and I was not happy with that. So now 2.5 years after parting the SC2, here I am in the new 2004 WRX that will be made into hopefully my Nationally Competitive STX car. It's going to be a fun ride!

Meet Boris - April 14, 2010

Just quick photos to get this show underway, as I said the car is all stock right now. I haven't really had a whole lot of time to go over it yet or start cleaning up the engine bay, but some before photos are always nice to have around.

General Maintenance Update - April 19, 2010

Today after I got home I got to tackling all of the fluid changes and getting ready to do some other little things tomorrow and Wednesday. I did transmission fluid, rear diff fluid, and engine oil today. Tomorrow I'll be getting to changing the spark plugs, fuel filter, bleeding the brakes, and also installing a much needed boost gauge. In general over the next 2 days I'll work on cleaning the engine bay up and trying to get it somewhat up to my standards.

Also the hand photo hahah, that was first blood that the car has dealt to me lol. Special moment after buying a new car no matter the size of the cut lawlz. Also as you can see, just because it's a Subaru does not make it immune to jackstands hahahah.

1st Autocross Event - April 25, 2010

So today I had my first event ever with the new car. I wanted to run it, even if it wasn't setup just to give the thing a little shakedown and make sure there would be no extra problem arising after the other parts went on. It was on stock all-season tires to boot. Anyway I still had a blast, it was fun, and I couldn't find anything single problem with the car mechanical wise. It was a really good day.

The results on the other hand sucked. I ended up getting 7th in STX and 37th PAX time. Probably the worst finish I've ever had, but as I said my excuse was the car being all stock hahah. That's the last time this is going to happen trust me. Anyway checkout the sweet video hahah.

The Coilover Install and New Rubbers - April 30, 2010

Well today was a ridiculously busy day. Got the car all setup handling wise for autocross. I think the only thing I still need to pickup are front endlinks for the 24mm Whiteline swaybar. That will come in due time along with a good set of brakes. It's pretty easy to overpower them right now with a set of 245 Dunlop Star Specs.

For the coilover and spring setup I went with a custom set of Ground Control/Koni's. They are setup with a 500lb front and 550lb rear spring. It feels incredibly good on the street, nice and neutral for the most part, but can enduce oversteer if wanted.

The alignment on the car is -3 degrees camber front, -1.7 degrees in the rear with 0 toe front and rear, and as much caster as I could get out of the Ground Control camber/caster plates in the front. And now for the eye candy.

The goods, 2nd photo is my rear helper spring setup, not standard but definitely needed for a decent amount of lowering.

5/2/2010 WDCR SCCA Autocross #2

So after not being down to DC Region myself in over 2 years I figured it was definitely over due, especially since they have such a strong STX following down there at the moment. John and Travis always put on a good show in their 03 WRX, and now another competitor of the region Chike is putting together a serious RX-8 STX build as well. I also wanted to get an event or two in with the car setup before the big divisional at the end of May.

We all went out for our first runs, on a brand new lot mind you, and I think all of us were pretty stunned and happy just how great it was and how much grip we had out there. I came across with a 43.595 on my first run, which put me in 2nd position, Chike 1st, Travis 3rd, and John 4th carrying a cone. I was blown away with how well the car performed and knew it was going to be a good day with how close we were all running. The car rotated really great, power came on at the right times, it was just going well.

Second run I wanted to really push the car and see where I could make up some time. Unfortunately in doing so I carried a cone on the 2nd run and pushed a little slower. All our positions pretty much stayed the same after this run set.

Third runs really got the blood pumping. I myself wanted to calm down a bit and get a nice composed run in. John ran first and threw down a 42.853, which Travis then bested with a 42.762, RX-8 came across with a 43.463 and I came in at a sub 43, 42.957. Absolutely thrilled that we were all running so closely and knew something had to be done in the final run.

Fourth run John was up first and absolutely demolished us throwing down a 42.644 to take over the lead from Travis who can only muster a 43.3 on the final run. RX-8 came through with a flying pass of 42.868 to take away 3rd place from me by .089 seconds. I couldn't not do a better time on the 4th run with the current tire temperatures and only managed a 43.097.

So at the end of the day only .3 seconds separated 1st through 4th place.
1st John - 42.644
2nd Travis - 42.762
3rd Chike - 42.868
4th Adam - 42.957

Absolutely the closest battle I think I've had in a few years and well worth the trip down there. I'm really looking forward to running with those guys again at Divisional towards the end of May. If you guys are somewhat local I suggest checking this event out, it's going to be so much fun. I'll leave you guys with a video (incar and spectator) and a few photos from Danny Kao.

Nice build thread Adam. I'm definitely hoping to build my RX-8 into a nationally competitive STX car over the next 1-2 years. I'm way down on power at the current moment though, which hurts me on lots with elevation changes like Fedex.

I'm definitely looking forward to the Divisional!

Thank ya. I'm especially interested in where the RX-8 build is going. I was a mere few signatures away from selecting one of those to put together myself and develop. I really think in a year or so it may be the car to have in that class. What I liked about the WRX and what sold me on it though is when I decide I want more power and I want to go faster, it's a heck of a lot easier then trying to get any more power out of an RX-8. That was the biggest turn off to me unfortunately.

Your car was under $600? The Koni/GC stuff is not that expensive.

I was in the very same boat several years ago. I went with a new '06 WRX at the time, but then traded it in for an '06 RX-8 less than 2 years later. While the WRX had power (and could easily make more), I wanted something that turned.

If/when I sell the RX-8, I want to buy an MX-5 or the next rotary car (hopefully they'll bring back the RX-7).

Question Adam - did you go with 16" RPF1's? Looks like the top 5 in STX were all on enkei wheels!!!!

They are the 17x8 RPF1's. There really aren't any other WRX offsets in a wheel that light, definitely the one to go with on them. I wish I could run the +35's like it appears you have on your car, but they are too much for the stock WRX fenders. The dish on the wheel looks much nicer then what I have imo.

I think the "dish" on my wheels are due to them being 17x9 RPF1's, but they're actually a +45 offset. I could have gone with the +35's though - they fit w/ no rubbing.

I guess I should have said "coilovers"

The car was very cheap, much less than a good set of AST coilovers.

Adam is a very fast driver he took 1st place in STX driving someone elses car 05' Blue WRX the month before let them know Adam! He beat me by a whole 8 seconds that day.

After I did my whole suspension "operation stiffy" before 4-25 event which I beat you by .3 RAW in your stock WRX. (but we are a different class since my Legacy has a 04' WRX swap)

Both of those events I was on 205/50/16 Sumitumo street tires. Well problem solved I picked up OZ 17x7.5 35+ and bought new 225/45/17 Falken Azenis for $386(thanks vulcantire) so I hope that helps me get out of the 5th-7th place hole like we both are in.

BTW, will you be at Hershey PCA this weekend? I registered already.
Also thinking about Philly Region on the 15th. Gotta break in these tires.

I noticed that little line about Rollbars. Do it! Ill be excited to have a friend in the Hillclimbing ranks with me.

Definitely Fingerlakes National again, I had a blast up there last season and would not miss out on it. Depending on how far along the car is Lincoln is not out of the question either.
