    Ok, I have another set of questions (03 WRX 2.0)-
    The car came with a aftermarket turbo-back, cold air intake, and a manual boost controller. I don't know if it has been tuned, but I doubt it considering the codes it throws.
    I plan to get an up-pipe and an Accessport before getting it back on the road (replacing the transmission and FL axle now). Should I remove the MBC and reinstall the stock piece? I plan to use the Stage 2+ from the Accessport when I get it due to the car's existing modifications.

    Cobb's map notes clearly state what can and can not be used with their AP maps. Both the MBC and the intake need to be removed unless you get a custom map made for those particular mods.

    I was thinking that I'd need to, but wanted to check first.
    I'll start looking for stock pieces to replace them. Hope they aren't an wallet buster.
    How would I go about getting a map made for it? I know a local guy with tuning software who has (a lot) experience tuning turbo Hondas and the Eagle Talons. Would he be trustworthy to tune the car?

    Easy works for me, thanks. I'm not wanting to continue modding the car, just make it work with as much power and reliability as I can with the current mods.

    Welcome to the club

    I'd recommend starting a new thread in "engine modifications" as you will get more specific feedback that way.

    first mods

    Hey guys my wrx is pretty much stock i have only added the cobb cat back exhaust and a short shifter, I was thinking about doing a little more to it but im not looking to spend a huge amount of money on it. I was thinking of maybe getting a downpipe and the accessport and stage 2ing it. any other suggestions?

    I just got a stock 2002 wrx only thing I've done to
    is a full 3" turboback exhaust.Upgraded Inlet tube andEpoc prokit springs. Also fixing to
    get a nice cold air intake. I'm
    new to
    subies. I'm embarassed to say this but I
    was riding with the
    hondas I had a built prelude. But
    how much hp do
    you think
    I'm
    pushing after the intake. And
    what minor things can
    u do
    without getting into the head and stuff to get some
    good torque and hp gains. also
    thought about tuning the stock turbo to more
    boost. What would
    be safe? Thanks for everyone help

    Hondas are among the best cars in the world.

    The intake will not add power to your car. It is also unlikely to filter air better than the correct part.

    See the links in my signature for info on all components and what's what.

    Old thread bump...

    I'm trying to figure out if it is a BAD thing to have an intake with a COBB stage 1 map? I'm looking get an AcessPort and go stage 2 next summer once I get a TBE setup. Only thing is, my car had a Fujita F5 SRI installed on it when a bought it, along with a GReddy Profec B series II boost controller that I have turned off because I know better.

    Any opinions or first hand experience? I'm thinking it may be because the car can run lean since the map is not accounting for an intake?

    Always refer to the map notes - cobb . wrx accessport . map listing

    "Hardware Requirements: Otherwise stock vehicle with a STOCK INTAKE
    SYSTEM ONLY."

    It is about running lean. Some intakes are thought to be OK but I don't know about Fujita and am pretty skeptical.

    I've heard Fujita does make decent quality parts, but I have never heard anything about them on Subarus.

    Accessport maps will work ok with a SPT SRIs, K&N SRIs, and Cobb SRIs as they all still flow relatively close to stock, since the stock airbox is actually pretty efficient. Anything else, especially CAIs...I wouldn't use.
