chain. The turbocharged 22R-TE (sold from late 1985 through 1988) produced at 4,800 rpm and at 2,800 rpm. These engines are extremely well known for their durability, decent fuel efficiency and good low to mid range torque. However, its weakness is high-end power. The 22R has a large displacement and a strong block, but its comparatively long stroke and restrictive head limit its use in high revving applications. Thus, the Toyota 18R-G, 2T-G, 4A-GE and 3S-GE 4-cylinder engines are better suited for performance applications. A popular modification to the early 22R is to use a 20R head. Unlike popular lore, the 20R head does not have smaller combustion chambers. The misunderstanding originated when the 22R came out and an advantage was its higher compression ratio, so swapping a 20R block with a 22R, there was a compression increase. The 20R head has straight ports, so can flow better than the 22R head, improving high RPM power. The 20R head is a simple bolt-on modification for the pre-1985 block, but also requires the use of the 20R intake manifold, making it almost impossible (there's a lot of matching necessary) to use with the 22R-E EFI system. For blocks 1985 and onwards, further modifications are required.
