    Unless it's a OEM td04 it needs to be tuned. I would never attempt running a larger turbo without new injectors and fuel pump. If it adds power it requires more fuel, increasing IDC.. so there you go.

    Until you have replaced at least the following:
    Uppipe
    Downpipe
    Injectors
    Fuel pump
    Tuning appointment

    That car should be parked and not driven. Driving it in its current state will likely cause the motor to let go, leaving you with a pretty hefty bill.

    There isn't.

    Being in PA, you can either go to NJ/NY/CT/MD, depending on where about (N/S/E/W) you are.

    ^this.. all of those things are absolutely required to run a 16g. The engine should not be started until those parts are installed and the car is towed to a reputable Subaru tuner to at least get a base map put on it.

    Ebay and it said...
    I, on the other hand, can offer you a submarine. All wheels are still attached, it's in only 100ft deep, all you'd need is a bucket to take the water out. It should float just fine...
    You can't have everything - where would you put it?

    this is what it says on there DESCRIPTION: 02-06 subaru wrx / 04-07 subaru sti td05 big 16g turbo charger (direct bolt on for 02-06 wrx)

    THIS AUCTION WILL INCLUDE THE FOLLOWING:


    New TD05H big 16G turbo.

    TURBO SPEC:

    SYSTEM : JOURNAL BEARING

    COMPRESSOR :

    A/R 49

    WHEEL DIAMETER 48.3 / 68mm MM

    ACTUATOR 0.8 BAR

    TURBINE:

    WHEEL DIAMETER 49.2 /56MM

    It has a big 16G compressor wheel, Td05H turbine wheel, and a specially designed turbine housing. It is ported and has a bigger waste gate. It fits 02-06 subaru wrx without any modification. This is a good upgrade for stock or mild tuned wrx's. average gain is around 70hp on stock boost and stock injector.

    First off, what is already done to your car?

    Second, even a TBE and tune will max the stock injectors on a 2003 WRX. While you may run it on a 2006+ WRX (565cc injectors vs. 420cc injectors on 2003 WRX) with stock injectors, you MUST upgrade your injectors and fuel pump to run properly on a Bugeye.

    You will need (bare minimum) 565cc injectors, 3" exhaust, larger TMIC, and an uprated fuel pump to install this turbo.

    I can't believe you're arguing with senior members on this forum using "But ebay says __" as an argument. The Ebay advert even states "used with stock boost control." Well no ****. The stock boost control works with any turbo you want. I personally would have never bought that turbo given the mis-information. FYR, if you paid less than $800 for a new 16G, you've likely bought a Chinese knockoff and I doubt that will last more than a few thousand miles. Good luck.

    Exactly.. you can see right there in the description that the seller is lying their ass off. That should be a big red flag not to purchase the item. You potentially did irreversible damage to your engine substantially shortening the life of the car, but I guess you're right, that's not that bad.. someone could have been killed or something.

    I'd recommend getting that turbo off, then finding a good tuner who will advise you on how to properly mod the car.
