The 4A-FE DOHC engine

The 4A-FE DOHC engine is very simple, reliable, durable and economical. This engine will never give you a problem if you maintain it well.
1.8L 16 valve model 1ZZ-FE . It has lightweight aluminium block and aluminium head.
Tuned intake manifold allows the engine to perform more evenly.
No more timing belt - using the chain instead allows to reduce maintenance cost. Models after 2001 come with variable timing for better efficiency.
This engine also appears to be very reliable. It has impressive power (120 h.p) and really low fuel consumption. The engine runs very smooth at any speed range, I'd only mention that it's a little more noisy than previous model.
