The Toyota 22R In Review

22r engineIt has often been said that they don’t make them like they used to and in all likelihood the analogy being used here was for the Toyota 22r. This engine is part of a range of engines that have been serving the Toyota family of automobiles since the fifties. The first R engines were applied to vehicles like the Super, Crown and the Toyota Master. Decades later, the R engine is still what some like to think of as an indestructible beast and has evolved into the 22R.

The Evolving 22R

The tenure which began in 1981 with a 2.4 liter 8-valve engine and ended in 1997 proved very successful for Toyota, and the vehicles that it was used for. By this time, Toyota had already proven to the rest of the world that their R engines could march with the best so them which is why it was no surprise when the 22r gathered the same respect as its predecessors. With a history of blazing trails through reliable engines the 22r had its sights set on far greater achievements. By the third quarter of 1982 Toyota had determined that the world was ready for a fuel injected engine. This is when the company introduced the 22R-E.

Performance Goals

Whether it was a lack of achievable goals set by the manufacturers or simply a need to perform better than everyone else, the 22R-E was destined to face greater alterations. The 22R-E saw some major changes in its design in a clear attempt to make it more compatible with parts from prior designs. Some of the parts that were affected were the pistons, the cylinder head, timing chain and the water pump. With so many parts being reworked to the original 22R, in other words, a roll back of sorts, the question about which engine it more closely matched was constantly being brought up by onlookers.

The Required Boost

Toyota was not going to be outdone in the realm of high-powered motor vehicles and by the late 1980s, they introduced the 22R-TE. This was a turbo charged engine, which put out 135 hp at an rpm of 4,800. Most people who came it contact with these engines agreed that as far as fuel efficiency was concerned the 22R-TE was more than adequate. Unfortunately, the durability that this version of the 22r put forth came with its own set of challenges, and most of them were centered around the high-end power limitations.

Serving A Purpose

With six years of service, the 22r had its design changes and was used in a variety of different automobiles. In 1981 the Toyota Hilux, Celica, Toyota pickup, Cressida and Corona all benefited from the 22R. Some of those models went on to take advantage of the 22R-E during the second half of the decade. With a large displacement, the 22r is said to adapt better to certain performance applications. It is important to note that users who wish to modify the 22r for further use will have decent results with the 20r head.
