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."
1KR-FE
"Toyota three-cylinder in the Aygo, Citroen C1, Peugeot 107/108 and Yaris. Simple, light and cheap to run with a maintenance-free chain. Watch two things: the water pump on 2005-2009 cars (an uprated pump came in 2009) and the oil level, which owners report dropping on some engines."
