VIN: JF1GD70666L505750
3rd owner of this car, 2nd owner after the motor rebuild. Noticed that the old owner:
Previous owner built this from the ground up, and I've done a more work making this thing a bit more "streetable" for daily driving. I've never been heavy into modded cars, so when I bought this it was a trial by fire. Needless to say I learned a ton, had a ton of fun, but man there is still so much to learn. In the 3 years I've owned this I've only put about 18k miles on it (and half that in cash into the car :/). I always lived close to work so my milage is super low.
I'm not going to say this car is perfect. Its 11 years old. Small dings, small a couple small plastic pieces are missing on the body. When the ECU is reset, its a bit of a slow learner. I don't really want to take **** apart and part, so I'm going to include everything I have related to the car. (fuel filters, 10w-60 Oil, fuel hoses, old injectors, old fuel pumps, old headlights, sound system)
The reason I'm selling is my wife and i bought a new truck and our family cabin. Her car is newer, and worth less than mine, so this toy's got to go.
All new work has been done by BK industries .

Professional Tune by BK industries
Here is what I've done to the car since I've bought it.
timing belt and water pump, fixed up some loose parts on the motor
New all terrain tires
2 mbquart 12's, with a 500x2 (rms) Rockford amp
Eclipse 75X4 (rms) amp
Kenwood deck that can support 6 channels of output.
After market headlight replacement. (Old headlights had the faded look)
New fuel pressure regulator.
New Spark plugs
Toned back the injectors from original 2150cc to 1000cc (still have the old injectors)
New Fuel Pump
Full re-tune from bk industries
Front spoiler
Wheel crack fix
Clutch master cylinder re-build. (O-ring blew out)
Added the spoiler support stabilizers (little plastic pieces easily removable)
New EXEDY Hyper Carbon-d twin plate clutch ($1700 in parts alone)
Replaced rear diff.
Just fixed front lip due to high levels of snow this year causing some damage
NOTE: This car is a two parts and a re-tune away from 600hp. The previous owner had 490whp on 92 and 600whp on E85
with the 2150cc injectors with dual walbro 255lph fuel pumps, which will include with the car. With those big injectors, the idle could never become stable, and E85 is a pain in the ass to get in Boise, which is why i toned it back a bit.
