\"Subaru<\/a><\/p>\n

Prime Motoring<\/a> transformed this Subaru WRX STI into a monster. The engine bay now holds a destroked 3.2 L EZ36 flat-six built by Outfront Motorsports<\/a> backed by a six-speed sequential transmission. The motor uses a modified EZ30 crankshaft, forged rods and pistons, GSC S1 camshafts, ported heads, AJ’s Garage<\/a> intake manifold, and a Precision 7685 turbocharger. E85 fuel is fed by three Walbro pumps in a surge tank to six FIC 2150 injectors. The motor is tuned by Jr Tuned<\/a> on a Motec M150 ECU. The motor made 1281 hp (942 kW) and 1021 lb-ft (1384 Nm) of torque to the wheels on 52-55 psi (3.5-3.7 bar) of boost.<\/p>\n
