This issue was cured in the 2003+ versions of the 1ZZ. The main components that cause this oil burning issue are the piston rings just like 2AZ, and the valve stem seals. The main being excessive oil consumption which many Toyota four cylinders are known for. Just like the 2AZ engine, the 1ZZ does have a couple of known issues. Their larger applications received larger engines with more horsepower and torque. You’ll notice that most of these applications are fairly small. Toyota put this engine in so many different vehicles because of its reliability and good performance, especially with the later ZZ engines. The 1ZZ engine was equipped in various automobiles ranging from sedans, coupes, small SUVs, and mid-engined sports cars. Because the 1ZZ uses a long stroke and a low redline, total horsepower is relatively low compared to something like a Honda B18C. Horsepower and torque are typically very unbalanced on small four-cylinder engines since most small engines focus on creating horsepower through a high redline. It’s worth mentioning that while total horsepower isn’t particularly high, it’s very well balanced with torque. Valvetrain: Dual Over Head Cams – Four Valve per Cylinder.For the most part, though, this engine is designed to run on standard quality gasoline. Some versions of this engine are specifically designed to run on E100, which is a popular fuel in some South American countries like Brazil. Toyota increased power output on the later versions of this engine through ECU tuning and a lightweight rotating assembly. You can still find some of these superchargers used on eBay, but they’re getting harder to find by the day. The only models that received the TRD Supercharger kit were the Corolla, Matrix, and Pontiac Vibe. This engine features technologies such as multipoint fuel injection, VVT-i, forged connecting rods, and an optional supercharger for some models. Thanks to the high 10:1 compression ratio, the 1ZZ also provides great efficiency. Unfortunately, a long stroke can make it much more difficult to create high RPM performance, but the large amounts of torque help cover that up. You can tell from those specifications alone that this engine is fairly torquey, thanks to the long stroke. It’s a 1.8L with a 79mm bore, 91.5mm stroke, and a 10:1 compression. The Toyota 1ZZ-FE is rather obviously the first engine in the Toyota ZZ family.

The ZZ engines are so good that Lotus used them in their Elise. Their previous performance engine family, the 4A engine family, used a cast-iron block design. The ZZ engine family was the first four-cylinder engine family from Toyota to use both an aluminum block and an aluminum cylinder head, which saves a ton of weight. As a whole, the ZZ engine family includes a few different variants, each with its own pros and cons. But, unlike the AZ engine family, Toyota built the ZZ engine family for excellent performance. Toyota designed the AZ for great fuel economy, and it’s still in production today. The 2007 model year no longer offered a GT or all-wheel-drive option due to poor sales and new federal emissions standards.Ģ005 Pontiac Vibe specs, photos, mpg, towing capacity, size - Photos, Pics, Wallpapers, Images.If you’re a Toyota enthusiast, you may have heard of the Toyota AZ engine. Engine power claims were decreased for 2006 as a result of Toyota's re-testing of its engines for the new Society of Automotive Engineers ratings standard. Power ratings for the first three model years were slightly higher, with the GT up to 180hp (134kW), the base model rated at 130hp (97kW), and the all-wheel drive model rated at 126hp (94kW). The Vibe was first produced in 2002 and went on sale as a 2003 model. There have been some minor changes between model years. The Vibe is currently the most fuel efficient vehicle sold by GM in North America, but this will not be the case with the revised United States Environmental Protection Agency testing procedures in 2008. Powertrains available for this car are a Toyota-built 1.8L straight-4 16-valve engine producing 126hp (94kW) on the base model (manual or automatic transmission), 118hp on the all-wheel drive model (automatic only), or a version with VVTL-i producing 164hp (122kW) for the GT (manual 6-speed only). The 2007 model year only offered the base model. The 2003-2006 Vibe was available in an economical base trim, an all-wheel drive mid-trim, or a "sporty" GT with more power.
