Toyota Engine Technical Specifications

2007 saw a major shift in the Toyota Tundra Engine lineup. Toyota went from two engines to three: the 5.7L 3UR-FE, the 4.7L 2UZ-FE, and the 4.0L 1GR-FE The last generation of Toyota Celica engines saw to 1.8L motors.

The eight cylinder 5.7L Toyota Tundra Engine is the largest Toyota engine in use in North America. This motor is DOHC with 32 valves, and makes use of dual VVT-I, which means the valve timing is variable both on the intake and exhaust valves. The bore size is 94mm and the stroke is 102mm. Should you need to replace this motor in your vehicle, I strongly recommend you buy a used engine, since a new one will set you back just under $20,000. There is unlikely to be a strong remanufacturing market for this engine, since the magnesium alloy head is difficult to work with. This engine is produced at Toyota's plant near Huntsville, AL.

The 2UZFE is a 4.7L Toyota Tundra engine also produced at the Huntsville plant. It also has a 94mm bore, but the stroke is reduce to 84mm. Again, we have a 32 valve DOHC. There is not dual VVT-I on this engine though – only variable valve timing. The 2UZFE utilizes a cast iron block and aluminum heads.

The 1GR-FE is a six cylinder, 32 valve DOHC 4.0L engine. This engine uses VVT-i, which mean that the valve on the intake cam is variable. Further, this engine cannot be bored out. Toyota has gone to an elliptical shape intake port. They claim that this is to reduce fuel consumption via more evenly distributed fuel, but the cynic in me feels that this is merely an attempt to make the engine nonrebuildable.

Getting into Toyota Celica engines, we first look at the 1ZZFE. This engine was built for US vehicles in Cambridge, Ontario, Canada and in Buffalo, West Virginia. It is a 1794 CC, 16 valve DOHC motor, with a bore of 79mm and a stroke of 84mm. All 2000-2005 GTs have the 1ZZFE. This engine utilizes a timing chain instead of a chain. A timing chain is considered to be of higher quality than a belt.

The upgrade of Toyota Celica engines is the 2ZZGE. Also a 16 valve DOHC engine, the bore is 82mm and the stroke is 85mm. Japanese produced only, this engine utilizes a 11.5:1 compression ratio requiring gasoline with a 91 octane minimum. This is a dual VVTL-i system, which means that the valve lift varies according to need on both the intake cams and the exhaust cams, greatly increasing performance.

Both Toyota Celica engines could be mated with either an automatic or manual transmission, though only the GTS could get the six speed manual transmission.

About the Author

Every Toyota Tundra engine I've encountered has been of the highest possible quality. The same goes for all Toyota Celica engines I've run into. Well maintained, these motors should run "forever."

Chevy guys N girls i have a 408 sbc i need carb advice?

this little mouse has aluminum heads with 2.05 intake and 1.625 exhaust valves a comp 294 degree cam with .560 lift it has 1.6 roller rockers and 10.89 compression the intake is a holley pro dominator dual highrise the bottom end is all lightened forged parts its in a 79 z28 with a 4 speed and 4.11 gears car weighs 3,550 lbs and needs carbs to be finished everything is matched to peak horse at 6800 rpm some street use but its main use is shutting up my cocky neibor and his 89 ford mustang thanks for your help

Most dual quad intakes were designed to use Holley 4160's because they have no metering block on the secondary side and are more compact than the 4150, giving more clearance.

If it were me, I'd use a pair of 525 cfm Barry Grant Road Demon Jr carbs. The secondary side has a fixed-jet metering plate, which in conjunction with the float bowl configuration allows for a shorter overall length. This allows the Road Demon Jr to fit on most inline dual quad manifolds originally designed for dual 4160 Holley carbs.
