Extreme performance modified 2005 Subaru Impreza WRX STi.


This Crystal Grey 2005 WRX STi has been performance modified to the 10^th degree and develops an astounding 530hp AT THE WHEELS! We have nearly $30,000 worth of performance upgrade receipts on file with this STi, as well as a dyno sheet documenting 530hp at 6350rpm and 453lb-ft at 5400rpm.

Not for the faint of heart, this STi is one of the most extreme performers we've had on our lot, hands down. The car is powered by a professionally built Maxwell Power "Power Factor" EJ25 2.5L engine that has been upgraded with a Kelford Cams cylinder head modification, upgraded Kelford cams, custom JE pistons, STi crankshaft, a Garrett GT35R turbocharger and TIAL blow-off-valve. Further upgrades include an MPS top feed fuel rail conversion, front-mounted intercooler, ceramic coated Agency Power unequal length headers and a Blitz NUR SPEC R exhaust -- among many other upgrades (see below).

To handle the extreme performance, the 6-speed transmission was upgraded with an ACT StreetLite flywheel and ACT Extreme Pressure Plate. Likewise, the factory STi performance suspension has also been upgraded with BC adjustable coilovers. Brembo HD performance brakes provide stopping power behind 5zigen FNO1R-C lightweight wheels. All performance upgrades were installed here in the Seattle area at a local Subaru specialist.

Factory features of this STi include HID head lamps, STi aero bodywork, driver controlled locking center differential, sport seats, auto climate control and a 6-disc CD changer.
