Toyota 2JZ Engine (Everything You Need to Know)
Updated: Feb 2
✔ This article has been fact checked.
Since 1991, the 2,997 cc (3 litre) 2JZ has been manufactured, first released in the 1991 Toyota Aristo. The cylinder has an 86 mm stroke and an 86 mm diameter. VVT-i variable valve timing was introduced for the 1998 model year.
While maintaining the same bore size, bore pitch, and general architecture, this engine has a higher block deck and longer connecting rods to suit the 14.5 mm (0.57 in) stroke increase.
In the US, the 2JZ-GTE was only offered in Supra Turbo models from 1993 to 1998. It was a brand-new design that was entirely independent of the 7M-GTE from the previous Supra.
The 2JZ-GTE was first released in Japan in 1991 under the hood of the Toyota Aristo and continued to run in a few Japanese Supras until 2002, when the car was completely phased out.
The 2JZ-GE, a naturally aspirated engine that is more accessible and built on the same short-block and almost similar but higher-compression rotating assembly as the 2JZ-GTE, is only capable of producing roughly 230 horsepower.
In this article, we will discuss the 2JZ engine and everything there is to know about it.

The 2JZ-GE is a well-liked variation. The engine produces 209-220 lb-ft (283-298 Nm) of torque at 4800-5800 rpm and 215-230 PS (158-169 kW / 212-227 bhp) at 5800-6000 rpm.
An aluminium head with four valves per cylinder and, in certain models, a cast-iron cylinder block with VVT-i are used with sequential electronic fuel injection. The distributor system of the 1JZ-traditional GE was replaced by the DIS, which was included into the VVT-i variant.
It used a single coil to ignite two cylinders, one of which was ignited by spark plug wire, hence it wasn't a genuine COP (Coil-On-Plug, also known as Plug-top coil) ignition system.
