HISTORY

In 2004, I got a 2000 Impreza OBS which was not only my first car, but also my first subaru. However, I only had that for 4-5 months until I wrecked it. Very minimal mods on it (KB short shifter, etc)





After waiting (and looking) for 6 more months, I finally came across a '99 RS coupe. I picked it up from a local Honda stealership for $9,500 in August of '05. Right after buying it, I put on an L hood and took off the rear wing. I ran it like that for a while.





And this is where everything really started to take off. I'm going to do the best I can to summarize what happened in the best detail possible between when I bought the car and now. After that, I will continue to update this thread as time goes along.

2005/2006 UPDATE

I got a set of STi wheels/tires, Prodrive P1 springs, kyb agx's, jdm V7 WRX seats then later a Corbeau forza, and a lot more. Got rear ended by a dump truck this year and got a lot of fresh paint and JDM tails out of it.










Later I traded for a set of Gold STi wheels.

newbie ? but how did you get the sti wheels to fit on your car?
'04 STi wheels are 5x100 and the right offset. It's the tires that won't fit. 225's will rub. I've had all 4 fenders rolled. You only need the rear two rolled to fit 225's unless you're reaaallllly low. I rolled the fronts since I'm going to run 245's next summer.

I started this journal a while back, but didn't do a very good job. I started updating everything today. By tonight, I should have updated everything up until the current state of my RS with descriptions and pictures.

05/01/08: rear MLSD

A week or so back, I installed a JDM V2 or V3 (seller didn't know which) JDM WRX rear Mechanical LSD with matching axle shafts. I also threw in KB rear diff/crossmember bushings. Here's some pictures from that install.

Just getting set up.


My brother lending a hand with the new JDM mLSD


The new unit.


Old open rear diff coming out.


Completely out.


MLSD set up to be lifted into place.


Picture of the whole mess.




Right now, I'm waiting to get my hood vents, bumper vents, and fog covers back from Subajay. He's repainting them since last time he got PSM instead of STM. I'm also scheduling an apt. at Fastrack Auto in Peabody, MA to get cornerweighted and aligned (with rear camber bolts).

Should be getting cornerweighted and aligned this saturday. Can't wait! I'm super pissed though. I just found out that my CC got a lot of charges yesterday that I never made. I'm just glad I caught it before too long. Just cancelled the card and am waiting to hear back from my CC company. This sucks.

I think I've decided to go a different route than a swap. I think I'm going to do a mild N/A build. I just posted an ad for a spare motor. This is a rough idea of the setup I'm aiming to start putting together.

EJ251 (phase II SOHC)
Cobb spicy cams or delta regrinds
head work (valvejob, port, polish)
lightweight flywheel, upgraded clutch
EL headers
high flow cat pipe
Rallitek PP6 piggyback
TB spacer
maybe extrudehone the Intake manifold
LW pulley
group N motor/tranny mounts (might go with cusco ones)
remove AC system
I'm thinking about ditching all the ABS eqpt. and installing new hard lines everywhere.

already have: COBB CAI, stromung CBE


plus lots of little things like gaskets, seals, timing belt, tensioner, etc. to bring the motor back to a healthy state. Still deciding on a lot of parts/things. Been reading up and doing my homework. I thought about building up the bottom end and valvetrain, but I don't really want to spend that much money right now on my RS.

I only need ~152ish WHP to have the stock power : weight ratio of a stock WRX and this setup should get me in that neighborhood. :)
