Pictures & Mods
Welcome to,

There are many great sites about Subarus and in particular the WRX and STi versions of the Impreza so I won't try to duplicate what they have already done. I'm just putting up this website to show the mods I've made to the car.

The main thing is changing the injectors & fuel pump to change over to 100% e85. I used the standard Walbro pump and 1100cc injectors. Access port allows tuning. Other than that and a KN air filter, nothing has been done to the engine.

Other mods: Volk Wheels, Coilovers, an X-Brace, a bunch of JDM trim pieces including the dash, door sills and front grill.

Best sites for e85 station location are:

Best fuel mileage with 100% e85 came on 3/12/15. A 161.7 mile trip took 8.6 gallons of e85. The car was driven 90% highway, one part hilly, the rest flat. No A/c, driving the speed limit and no rapid acceleration. This comes out to be 18.80mpg. Compare that to the official government number of 23mpg on gas and you see e85 doesn't have to mean plummeting mileage. That's only a 20% drop and that's assuming you believe the government's numbers. It's the tune and how you drive. Tune for max torque at very low boost, use that torque w/o getting into the boost heavy and upshift as soon as you can. Keeps the revs under 3K at all time. 2200-2500 seems to be a good spot to shoot for.

Things that helped get this number:

  • Coilovers put the car very low to the ground. Ground clearance from the bottom of the front spoiler to the ground is exactly 4". The car sits level so the back is pretty low too. I could drop it another 1/2" but getting into some places is already tough enough, so I'll stick to 4" of clearance.
  • Perfect weather: 68-72F, no A/c was used.
  • Perfect weather: Slightly overcast, no winds of any kind.
  • Goodyear F1 DS3 tires pressure set at 38psi.
  • Perfect weather: All windows and sunroof were kept closed for 80% of the trip. Only when I neared home did I roll down the windows and open the sun roof.
  • Driving like granny. Drove the speed limit almost everywhere, only exceeded it a few times and only by up to 5mph over.

    So the next time someone tells you e85 will kill your mileage you'll know they have their foot in it all the time. ;-)

    Highlight the features of the Limited edition in the hopes of generating more support for this type of vehicle. When you buy the Limited, you get the following changes and additions to the Impreza WRX Sti:
    • Leather Interior, really very nice leather too. Very soft, not hard like so many other japanese cars.
    • Heated front seats.
    • Sun Roof.
    • Front chin spoiler. (I think it's really sharp looking.)
    • Lustrous silver painted wheels.
    • Fog lamps.
    • Auto dimming rear view mirror with compass.
    • Fold down rear armrest with access to the trunk.
    • Emblem noting the number of the vehicle.
    • Pearl White or "Urban Gray" paint. The gray is more a rich, deep, dark silver color than gray to me.
    • Delete rear wing, IOW, "The Picnic Table" is gone. :-)
    • Delete roof mounted rear spoiler. Makes for a cleaner look.

    The total package creates a car that can stand out, or blend in, depending on your surroundings. By that I mean, on the standard STI, the big wing totally dominates the looks of the car. With the wing missing, now you can see the lines of the car and appreciate the ground effects, the fender flares, and the overall look of the vehicle. It has a European/Japanese hybrid look to me. One I very much appreciate. :) One thing they could do to clean up the lines of this car is remove the ugly front license plate mounting boss. - Drag Racing Timeslip Database
