    What are your goals, and what is your budget?




    I could make a very compelling argument that the best turbo is the stock one and the best FMIC is the one that isn't ever installed.

    vf39, sti top feed blue injectors, walbro fuel pump, sti tmic, and a way to tune it (cobb AP) Total w/o AP roughly $900 or less and with used AP can be around $1200 or new AP for around $1400.

    Don't forget the exhaust..




    $2500 isn't going to get you the "best" anything. Although the term best itself is widely open to interpretation. The best spooling turbo for your car is the stock one. And unless you're going with a 20g or larger sized turbo, a FMIC is going to reduce your performance. Most of the decent FMICs cost between $1200 and $1600. A good quality turbo is going to cost between $1200 and $2000 alone.. injectors are in the $500 range. Exhaust is going to be $500-$1200.

    Assuming you got a turbo large enough to warrant switching to a FMIC your stock engine isn't going to last long, maybe not even long enough to finish the tune.


    So if you want the turbo, FMIC, and engine built to handle it you're already pushing $10,000.. and you won't be able to use that power without breaking your transmission, so there's another $1600-$6000.





    The "best" you can do for $2500 IMO would be a VF39, like yamaha_rider619 said.. buy all used parts and hope they're in good condition. Also be sure your engine is in good condition and up to date on scheduled maintenance before upgrading anything. Depending on your mileage and the condition of the car you could easily spend all of that $2500 just on routine maintenance alone.

    im a bit confused are you saying that putting a larger turbo on the car without beefing up everything else wont work. or are you saying that the engine just cant handle that much at all.

    also once again excuse my ignorance but who makes the vf39?

    ok nevermind im dumb its the turbo off the sti? i think

    VF Turbos are made by IHI...they're factory STI Turbochargers and later year WRX factory turbochargers. The VF39 I can't remember which car that is off of.

    Both. Putting a larger turbo on a car without proper supporting mods is not only pointless, it's dangerous. The turbo introduces more air to the engine, so you will need to be able to supply it with more fuel as well. Not only that, but you will have to upgrade the exhaust first and foremost. Even on a totally stock car the factory uppipe on your car is a hazard because of the pre turbo catalytic converter that can potentially break apart, ruining your turbo and probably engine too.


    Luckily, there's little that can go wrong with a used exhaust system (as long as it's stainless steel). So you can probably find a decent aftermarket exhaust that's used and affordable. I bought my first 2002 WRX when they were first released so I had to buy new. If I remember correctly I spent nearly $1000 on the turboback exhaust (which still looks practically new), and I gutted my factory uppipe for free. Now days you can probably find sufficient used exhaust parts for around $300.


    As far as the turbo goes, when you upgrade you need to get larger injectors and a higher flowing fuel pump. Without those things your car will never be able to supply enough fuel to use the turbo. Going to a slightly larger turbo (like the VF39) will probably be okay as long as your engine doesn't have a ton of miles on it and it has been well maintained. It's always a good idea to do a compression test before hand just to make sure the engine is healthy. And if you're not up to date on all your maintenance it would be very poor decision making to spend money on upgrades while neglecting what needs to be done in the first place. After 100,000 miles you not only need to do the full service including spark plugs and flushing and replacing all fluids, but you also need to change the timing belt, tensoner, water pump, cam seals, etc. This service can easily cost over $1200, but is essential to ensure your car continues running as it should.


    Even if the engine is low mileage/good condition, there is only so much power it can make before you break something. On the ej205 that's around 330-350whp. And don't forget that the brightest flame burns quickest.. meaning the more power you make, the shorter the lifespan of the engine.



    On top of all that, when you increase the power output of your engine you are going to be much more likely to break other drivetrain components, namely the transmission. Assuming you have addressed that issue, you also need to improve the suspension and brakes as well, otherwise you're going to end up in a ditch, or wrapped around a telephone pole somewhere, and no one wants that.

    i was just wondering if any of you have any 02 bugeyes, and if they still run good with atleast 100,000 miles on them.

    Mine runs great. Frankly, if the car did not run well with only 120,000 miles, there is no reason to buy another Subaru. Any car should be able to do this routinely at this point.

    Here's the catch though: My car is maintained by the maker's schedule using authentic Subaru parts or at the very least, OEM parts (the difference being that the parts may be labeled variously but the supplier is the same whether the part says "Subaru" or not). No unauthorized, no imitation, no aftermarket parts. YMMV.

    I have a 2002 bugeye. It had 139psi on all 4 cylinders at 115k and runs perfectly now with 123k. first gear syncro on the tranny is a little worn but other than that the drive train is in great shape.

    I think mine is showing ~108,000 miles on the odometer and it's running good.. of course there's hardly anything original left on the car.


    There's a 200,000 mile club around here somewhere.
