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

This 2004 Audi S4 (B6) arrived at BrG Motors<\/a> for a motor swap. Auditography<\/a> reports the company swapped the factory naturally aspirated 4.2 L V8 for a twin-turbo 2.7 L V6 from an Audi RS4 (B5) Avant. BrG Motors stroked the motor to 2.9 liters and installed naturally aspirated-spec camshafts. It also received two Garrett G25-550 turbochargers and titanium exhaust. The V6 produces 715 hp (525 kW) and 880 Nm (649 lb-ft) of torque. Behind the motor is a PTB Racing twin-disc clutch and six-speed manual transmission and Quattro AWD drivetrain. The modified powertrain allows the car to reach 0-100 km\/h (0-62 mph) in 3.5 sec and 100-200 km\/h (62-124 mph) in 6.8 sec. <\/p>\n
