The 2JZ engine was an engine manufactured by Toyota. There are 3 2jz of the engine that came from the factory, 2jz.

With its two sequential turbochargers, this 3. But it wasn't just what Toyota itself did with this engine that sealed the Supra's place in history. It didn't take long for the aftermarket to realize that this engine could be tuned to make way more than horsepower with seemingly no detriment to reliability. It's not uncommon to see modified Supras pushing out well over horsepower with no problems. Even a conservative tune can turn a Supra into a supercar-rival with relative ease.

The 2, cc 2. The 1JZ-GE is a common version, with a compression ratio. All of these models only came with a 4-speed automatic transmission; no manual gearbox option was offered. The first generation 1JZ-GTE employs twin CT12A turbochargers arranged in parallel and blowing through a side-mount or front mount air-to-air intercooler. With an 8. The early generation 1JZ-GTEs combined the inherent smoothness of an inline 6-cylinder engine with the revving capacity of its short stroke and early power delivery of its small, ceramic wheeled turbochargers. The ceramic turbine wheels are prone to delamination in the setting of high impeller rpm and local temperature conditions, usually a result of higher boost. The first generation 1JZs were even more prone to turbo failure due to there being a faulty one-way valve on the head, specifically on the intake cam cover causing blow-by gases to go into the intake manifold. On the exhaust side, a decent amount of oil vapor flows into the turbos causing premature wear on the seals. The later second generation engines had this problem fixed. In Japan, there was a recall made in order to repair the first generation engines, however this does not apply to 1JZs imported into other countries. The single turbo is in part made more efficient by the use of smaller exhaust ports in the head, this allows the escaping exhaust gasses to have more velocity as they exit the head, which in turn, spools the turbo faster and at lower RPM.

The 2JZ engine was produced from to The general architecture of the 2JZ is similar to the 1JZ , but it is not just a simple stroked version. The cylinder block is made of cast iron, strong and durable material. The 2JZ engine block is taller than 1JZ due to increased stroke by A new crankshaft with increased stroke also required longer connecting rods they are hot-forged. The first generation 2GZ-GE had an aluminum cylinder head with a straight forward design - four valves per cylinders, centrally located spark plugs, and belt driven double overhead camshafts.

In the hands of the right tuners, decimation is what the Supra was all about. It was a high point for the Japanese auto industry, and the 2JZ was a high-point for big, tough, iron-block straight sixes in passenger cars. Toyota only puts big straight sixes into trucks now, and its big rear-drive sedans have V6s. Any couple schmucks can drop a few thousand dollars to buy a 2JZ to cram into some old Nissan if they want to and make a high-horsepower car in their garage. The 3. Those high performance GTE models received different aluminum cylinder heads with unique intake and exhaust manifolds, higher-flowing injectors, recessed pistons offering lower compression ratios which allowed the engines to handle more boost , and oil squirters to keep the pistons cool. Because of these differences, the GE models, which you can find all day in Lexus GSs, are not as desirable in the tuning scene. That was a brazen lie.

Even a conservative tune can turn a Supra into a supercar-rival with relative ease. That's not great where weight is concerned, but for ultimate strength, it's ideal. Tools Tools. It's a fascinating look inside a legend, and full of valuable information if you ever take one apart yourself. Views Read Edit Edit source View history. The 2, cc 3. Then, there's the forged steel crankshaft, which is particularly strong. With an 8. Engineers also added oil spray nozzles for additional cooling of the pistons. Categories : Toyota engines Straight-six engines. There are 3 versions of the engine that came from the factory. The cylinder block is made of cast iron, strong and durable material. Surprisingly Affordable s Dream Cars. Fuel type. Production years.

The engine replaced the past Toyota 7M. The 2JZ is a simple sort of a straight 6 cylinder motor with a hard cast iron cylinder block and 3 liter displacement.

It also offers a great opportunity for tuning, showing outstanding power outputs for a small number of upgrades and modifications. In Japan, there was a recall made in order to repair the first generation engines, however this does not apply to 1JZs imported into other countries. Chris Perkins Senior Reporter. Valvetrain layout. The first generation 2GZ-GE had an aluminum cylinder head with a straight forward design - four valves per cylinders, centrally located spark plugs, and belt driven double overhead camshafts.

He street-parks a Porsche Boxster in Brooklyn, New York, much to the horror of everyone who sees the car, not least the author himself. This engine is not merely a stroked version of the 1JZ although they share a common bore size, bore pitch, and general architecture , but has a taller block deck and longer connecting rods to accommodate the It's almost as if Toyota designed the 2JZ with boost-hungry tuners in mind from the outset.
