# Toyota RZ engine
The Toyota RZ engine family is a series of inline-four gasoline engines that Toyota introduced in 1989 for commercial vehicles, beginning with the fourth-generation Hiace van. The family comprises the 2.0-liter 1RZ and 1RZ-E, the 2.4-liter 2RZ, 2RZ-E, and 2RZ-FE, and the 2.7-liter 3RZ-F and 3RZ-FE, and it powered vans, pickups, and sport utility vehicles through 2004.

## Development and launch
Toyota developed the RZ series as the engine lineup for its new generation of commercial vehicles. The company's own history records the 1RZ as an in-line, four-cylinder gasoline engine developed for commercial vehicles[1](https://www.toyota-global.com/company/history_of_toyota/75years/data/automotive_business/products_technology/technology_development/engines/index.html). The launch vehicle was the fourth-generation Hiace, released in August 1989, whose revised mechanical components included the newly developed gasoline engines, the 2-liter 1RZ-E and 1RZ units and the 2.4-liter 2RZ-E unit, together with a 2.8-liter diesel engine (3L) fitted to all 4WD models[2](https://www.toyota-global.com/company/history_of_toyota/75years/vehicle_lineage/car/id60001935/index.html).
The development work was documented by Toyota engineers in the company's technical journal. A paper titled "Development of TOYOTA 1RZ, 1RZ-E, 2RZ and 2RZ-E type engines" by four Toyota Motor Corporation authors including Toru Kawase (河瀬徹) appeared in *Toyota Engineering* (トヨタ技術), volume 39, number 2, pages 224 to 231, in December 1989[7](https://jglobal.jst.go.jp/detail?JGLOBAL_ID=200902037484829597).
## The 1RZ and 2RZ: the van engines
**1RZ and 1RZ-E.** The 2.0-liter 1RZ and its fuel-injected 1RZ-E variant served in the Hiace and the Hilux. Australian import listings show the Hilux of 1997 to 2002 taking the 1RZ-E, a 2.0-liter four with a five-speed manual transmission and rear-wheel drive[8](https://www.gearboxengine.com.au/toyota/).
**2RZ and 2RZ-E.** The 2.4-liter 2RZ-E was produced from 1989 to 2004 in Japan and only for commercial vehicles, fitted to the HiAce H100 from 1989 to 2004[4](https://mymotorlist.com/engines/toyota/2rz-e/). Parts catalogs for the 1989 Hiace Van Commuter (chassis RZH113R) list the 2RZ engine in Australian-market standard-type vans with a five-speed floor-shift manual transmission[9](https://partsouq.com/en/catalog/toyota/diagram/GENERAL/1989/HIACE-VAN-COMMUTER/RZH113R-RBMRSQ/catalog/711340/category/1/diagram/1501/illustration/150457C). The carbureted 2RZ served the Hiace from 1989 to 2005 in Australian listings as a 2.4-liter four with rear-wheel drive[8](https://www.gearboxengine.com.au/toyota/).
**2RZ-FE.** In the 2.4-liter 2RZ-FE only the No. 1 timing chain is used, whereas the larger 3RZ-FE adds a second chain driving balance shafts[10](https://diagnostdata.com/toyota/tacoma/i-facelift-2000-2004/remont/mechanical/engine-mechanical-2rz-fe-and-3rz-fe/other/).
## The 3RZ: the 2.7-liter truck engine
The 3RZ-FE is a 2.7-liter gasoline engine produced from 1994 to 2004 in Japan for pickups and SUVs[3](https://otoba.ru/dvigatel/toyota/3rz-fe.html). One owner-experience survey lists output of 182 hp for the 3RZ-FE 2.7[11](https://www.autohints.com/toyota-3rz-fe-27l-182hp-inline-4-cylinder-engine-15070).
Toyota fitted the 2RZ-FE and 3RZ-FE across its truck line, including the Tacoma, 4Runner, T100, and Hilux[6](https://cargeek.org/engines/toyota-rz). The 3RZ-FE appeared in the 1996 T100 alongside the 5VZ-FE V6[12](https://assets.sia.toyota.com/publications/en/om/OM34410U/pdf/omsource/1996om/96t100om/sect8/81.pdf), and in the Land Cruiser Prado (120 series) and fourth-generation Hilux Surf listed in Toyota's own engine lineage chart[5](https://www.toyota.co.jp/jpn/company/history/75years/vehicle_lineage/engine/gasoline/rz.html).
## Mechanical design
The 3RZ-FE repair manual shows a chain-driven valvetrain with a two-chain layout: a primary chain between the crankshaft timing gear and camshaft timing gears, and a No. 2 chain driving balance shafts. Service limits in the manual include a maximum chain elongation of 147.5 mm (5.807 in) over 16 links for the main chain and 123.6 mm (4.866 in) for the balance-shaft chain, with replacement required beyond those limits[13](https://toyotamanuals.gitlab.io/PZ471-Z00W0-CA/htmlweb/rm/rm991e/m_14_0004.pdf). The cylinder block houses two balance shafts, installed with thrust spacers, thrust washers, sliding keys, and driven gears[14](https://toyotamanuals.gitlab.io/PZ471-Z00W0-CA/htmlweb/rm/rm991e/m_14_0051.pdf).
Head fastening follows Toyota's torque-to-yield practice of the period: the 2RZ-FE cylinder head bolts are tightened to 39 N·m and then turned a further 90 degrees twice, and the connecting rod and main bearing caps use the same 45 or 39 N·m plus 90 degrees sequence[15](https://www.todomecanica.com/component/k2/download/2135_08f3aba9c5a37cf35d423d504583d8fb.html).
## Service life and reputation
The RZ engines built a durable reputation in truck duty.
## End of production
Production of the RZ family ended in 2004, with the 2RZ-E and 3RZ-FE both ceasing that year[4](https://mymotorlist.com/engines/toyota/2rz-e/) • [3](https://otoba.ru/dvigatel/toyota/3rz-fe.html). Toyota's technology chronology records that in August 2003 the company developed a new inline-four gasoline engine of the TR series for commercial vehicles, the family that took over the RZ's van and truck roles[1](https://www.toyota-global.com/company/history_of_toyota/75years/data/automotive_business/products_technology/technology_development/engines/index.html).
