    What did your brother say about the 04?

    The cars differ in mapping and aero.

    The 2,5L cars (06+ WRX and 04+ USA STi) are more torquey and quicker.

    See the link in my signature but before that, see the sticky threads in the Purchasing forum for how to buy a used WRX.

    Here's one, but the other threads in that forum are more informative so don't stop there:

    The only differences in the motors between 2002-2003 WRX and 2004 is the following:

    - Shim-over-bucket retainers changed to shimless buckets in late 2004
    - ECU Mapping
    - Crankshaft oil journals changed from drilled to cross-planar drilled for improved crankshaft lubrication

    Output remained at 227bhp and 217ft-lbs of peak torque.

    Neither model (stock) is "quick" by today's standards.

    How much do you think it will cost to push it to 300?

    Crank or wheel?

    Very different measurements here.

    Probably more than what you would pay for the car.

    Nah, not necessarily. Here's what I payed to get 300+whp:

    1. Tactrix --> $150
    2. AEM WBO2 --> $150
    3. Blouch TD05-18G --> $600
    4. DW 750cc injectors --> $350
    5. BPM TMIC --> $300
    6. TGV deletes and Phenolic spacers --> $75
    7. Custom 73mm intake --> $70
    8. Hybrid boost control --> $160
    9. Cobb Downpipe + Catback (new) --> $1225
    10. Walbro FP --> $90

    Total: $3170

    Now: If you subtract the price of the Cobb DP and Catback (for which I payed a premium), the price is under $2000. However, I self-tune, so you'll need to add in a $500 pro-tune to the mix.

    FYR, this is ONLY engine modifications. You'll want to balance engine mods with suspension and braking modifications.

    Also, a tuner can make a dyno read anything he/she wants by manipulation of the correction factors... just a thought. 300whp is a 130whp bump from stock.

    Just some info for the future. My oldest brother has a 2011 Mazda Speed 3 and my middle brother has a 2010 Gt(4.6). They told me that a wrx would be a great buy. Even with high miles! Thanks everyone.

    Right and that is also assuming he does all the installs himself and doesn't have to pay for that labor (not cheap).
