This 2007 Subaru Impreza WRX STi is powered by a replacement turbocharged 2.5-liter flat-four that was installed in 2023 and has reportedly been modified with a nitride-treated crankshaft, oversize pistons and valves, 272 camshafts, a Precision rotated turbocharger, and a front-mount intercooler. It is finished in Obsidian Black Pearl, and power is sent to all four wheels through a six-speed manual transaxle. Additional modifications include Aeromotive fuel system components, Injector Dynamics injectors, a TiAL external wastegate, an IAG header, P&L Motorsports exhaust pipes, TEIN coilovers, and a harness bar. The seller purchased the car in 2016, and the timing belt is said to have been replaced in May 2023. This modified STi has 95k miles and is offered in California with an accident-free Carfax report and a clean Alabama title in the seller’s name.
The car is finished in Obsidian Black Pearl (32J) and features an aluminum hood with a scoop as well as HID headlights, side skirts, power-adjustable mirrors, a roof spoiler, a rear wing, and a single exhaust outlet. Imperfections are noted in the paintwork.
Silver-finished 17″ 10-spoke BBS alloy wheels are mounted with Pirelli P Zero Nero tires measuring 245/45. Stopping power is provided by four-wheel disc brakes with Brembo calipers over slotted rotors. The seller states TEIN Street Basis coilovers have been added in addition to Kartboy subframe lockdown bolts and transaxle subframe bushings.
The front bucket seats are trimmed in black cloth with blue Alcantara inserts, and color-coordinated upholstery extends to the rear seats and the door panels. A blue-finished harness bar has been installed, and amenities include a CD stereo, cruise control, and automatic climate control. The trunk carpeted mat is missing.
The leather-wrapped steering wheel fronts a 160-mph speedometer, a tachometer, and supplementary readouts. An auxiliary gauge pod mounted atop the dashboard houses AEM readouts for boost pressure, air/fuel ratio, and oil pressure. The digital odometer indicates 95k miles.
The replacement turbocharged 2.5-liter flat-four was installed in April 2023 and has reportedly been modified with a nitride-treated crankshaft, CP .020″-oversize forged pistons, ACL Race bearings, ARP hardware, 33mm oversized valves, aftermarket springs and retainers, and 272 camshafts. The seller notes the car is tuned to run on 93-octane fuel via a COBB Tuning Accessport V2 and the engine’s redline is 7,800-rpm. Additional aftermarket components installed under previous ownership are said to include the following:
- Precision rotated 6266 ball-bearing turbocharger
- Aeromotive fuel pressure regulator with gauge
- Aeromotive top-feed fuel rails
- AEM fuel pump
- Injector Dynamics 1,000cc fuel injectors
- 4″ air intake
- 3.5″ front-mount intercooler with 2.5″ piping
- TiAL 44mm external wastegate
- TiAL 50mm blowoff valve
- Perrin four-bar MAP sensor
- Mishimoto aluminum radiator
- Moroso coolant expansion tank
- Oil catch can
- Killer B Motorsport oil pickup & baffle
- Cusco engine mounts
The seller states the timing belt was replaced in May 2023 along with an oil change and a fuel injector cleaning. Rust is noted on the exhaust manifold, and the hood prop is missing. The car has not passed a California emissions test.
Power is routed to all four wheels through a six-speed manual transaxle, a driver-controlled center differential, and limited-slip front and rear differentials. A Competition Clutch kit and a Cusco transaxle mount are noted to have been installed, and the seller reports the exhaust system has been modified with unequal-length headers as well as a P&L Motorsports rotated uppipe, downpipe, and Street Series exhaust system with a Vibrant muffler.
The Carfax report lists at least one open recall.
