The Toyota ZZ engine family is a straight-4 piston engine series. The ZZ series uses an aluminum engine block and aluminum DOHC 4-valve cylinder heads, a first for Toyota. The camshafts are chain driven. The two 1.8 L members of the family, the 1ZZ and 2ZZ, use different bore and stroke. The former was optimized for economy and torque, while the latter is a "square" design optimized for high-RPM power. The ZZ family replaced the extremely popular cast-iron 4A engines.
The seemingly complicated names Toyota gives its engines is actually quite simple. The first number denotes the engine block's generation. The next one or two letters, followed by a hyphen, specify the engine family. The remaining letters following the hyphen list the engine's features. For example, the 2ZZ-GE can be decoded as being the second generation of the ZZ engine series and features a performance head - wide angle valves (G) and Electronic Fuel Injection (E)
1ZZ-FE
The 1ZZ-FE is a 1.8 L (1794 cc) version built in Buffalo, West Virginia. Its production in Cambridge, Ontario was discontinued in December 2007. Bore is 79 mm and stroke is 91.5 mm. Output is between 120 hp (89 kW) at 5600 rpm with 122 ft·lb (165 N·m) of torque at 4400 rpm, and 140 hp (104 kW) at 6400 rpm with 125.8 ft·lb (170.6 N·m) of torque at 4200 rpm. The cylinders of 1ZZ engines are lined with cast iron. It uses SFI fuel injection, has VVT-i (on later versions) and features fracture-split forged powder metal connecting rods, a one-piece cast camshaft, and either a cast aluminum intake manifold or a molded plastic one.[2]
A bolt-on TRD supercharger kit is available on the 2003–2004 Corolla, Matrix, and Vibe.

Toyota announced a voluntary recall of Toyota Corollas and Matrixes equipped with 1ZZ-FE engines. The issue, which affects units sold from 2005 to 2008, affects the engine control module, and includes the potential for it to develop a crack on the module's circuit board, which can result in the car not starting, the transmission shifting harshly, or the engine stalling. The companies will begin mailing official recall notices to owners in mid-September, and will replace the engine control modules on affected cars at no charge. Additionally, Pontiac announced a voluntary recall of Pontiac Vibes from years 2005 to 2008 for the same issue.
