Antti Holtinkoski built his Toyota Corolla (E110) to race. In the engine bay they swapped a turbocharged 998 cc Toyota 1SZ-FE inline-four. In our previous article the motor produced 301 hp (221 kW) at 8831 rpm and 298 Nm (219 lb-ft) at 5883 rpm to the hubs on E85 fuel. In the offseason Antti rebuilt the 1SZ-FE for more power. It is now making 365 hp at 9809 rpm and 304 Nm at 7412 rpm to the hubs. Behind the motor is a Motor Design Sweden MD5 Ultralight five-speed sequential transmission and Volvo 760/780 independent rear differential.
