Toyota 2JZ Engine Specs
If you’re searching for Toyota 2JZ Engine Specs, Performance, Cylinder Heads, and Cam Specs, We Realise how tough it may be to obtain all of the Requires information Online. To Help you Research the Toyota 2JZ Engine, Our team is Created a Step-by-step Tutorial. Let’s go into the Subject.
The 2JZ Engine was produced from 1991 until 2007. A 3.0-liter inline Six-cylinder gasoline Engine powers the vehicle. It is one of the most well-known Toyota Engines, Particularly the twin-turbo 2JZ engine utilised in the iconic Toyota Supra.
A common engine variant is the 2GZ-GE, a naturally aspirated motor seen in Toyota and Lexus automobiles (such as Toyota Altezza, Aristo, Soarer, Lexus IS300, GS300 as well as SC300). It is well-known for its high quality and long life.
Due to the 14.5mm stroke, 2JZ engine blocks are taller than 1JZ blocks (0.57 in.). The first 2GZ-GE had an aluminum cylinder head with an easy-to-use design, four valves per cylinder centrally positioned spark plugs and belt-driven double overhead camshafts.
The intake valve has a 33.5-millimeter diameter, While the exhaust valve has a 29.0-millimeter diameter. Specifications for the camshaft are as Follows: Valve lift of 8.26 mm for the intake and 8.41 mm for the exhaust.
The Engine was Outfitted with a Conventional ignition system consisting of an ignition distributor and a Single coil. An Aluminum intake Manifold and Toyota’s ACIS Technology make up The intake. The Compression Ratio on an aspirated 2JZ is 10.5:1.
