Character

2ZZ-GE

"Yamaha-designed 1.8 for the Corolla T-Sport, Celica and Lotus Elise: VVTL-i switches to a high-lift cam around 6,000 rpm and it revs past 8,000. Early engines wore the lift bolts so the high cam stopped engaging (no engine damage; revised bolt from late 2002). No hydraulic lifters - valve clearance is a shim job. Not the 1ZZ with more power: a different, more highly strung engine."

1NZ-FE

"Toyota's 1.5 petrol for the Yaris/Echo and Asian-market Corolla (1999 on). Timing chain, port injection, no turbo. Its known wear points arrive late: oil consumption with age from about 150,000 km, chain and sprocket wear, and a VVT-i actuator that can rattle on cold starts."
