Guys,

	I have a very classic 1980 Corona "Luxury Edition" wagon (sport
utility - ha !) with a 20R engine.  What's amazing is the car is
un-killable.  Car has around 220K miles and even the 3 speed auto trans
still works fine.  Rust, however, is another matter.......  The Corona
wagon has little styling, but IMHO that's a lot better than the new cars
with the high doors (beltline) and big asses.
	Good scoop here on Toyota engines in general.

straight from wikipedia.....

20R
The 2-valve SOHC 2.2 L (2189 cc) 20R was produced from 1975 through
1980.
Cylinder bore was 88.4 mm (3.48 in) and stroke was 88.9 mm (3.5 in). 
Aluminum alloy heads were used.

Initial output was 96 hp (72 kW) at 4800 rpm (90 hp in California) and
120 ft?lbf (162 N?m) at 2800 rpm. Power was down slightly from 1978
through 1979 at 95 hp (71 kW) at 4800 rpm and 122 ft?lbf (165 N?m) at
2400 rpm. The final version, from 1979 through 1980, was down again at
90 hp (67 kW) at 4800 rpm and 122 ft?lbf (165 N?m) at 2400 rpm.

Applications:

1975-1980 Toyota Hi-Lux
1975-1981 Toyota Celica U.S. Version
1975 Toyota Corona U.S. Version

21R
The 2-valve SOHC 2.0 L (1972 cc) 21R was produced from 1978 through
1987.
Cylinder bore was 84 mm (3.31 in) and stroke was 89 mm (3.5 in).

Output in 1978, constrained by emissions, was 105 hp (78 kW) at 5200 rpm
and
116 ft?lbf (157 N?m) at 3600 rpm. Air injection and California emissions
equipment for the 21R-C (1982-1985) dropped power down to 90 hp (67 kW)
at 5000 rpm. The air-injected Japanese version, the 21R-U, produced 105
hp (78
kW) at 5200 rpm and 120 ft?lbf (162 N?m) at 3600 rpm but dropped to 101
hp
(75 kW) at 5400 rpm and 114 ft?lbf (154 N?m) at 4000 rpm in 1986.


22R
The 2-valve SOHC 2.4 L (2366 cc) 22R was produced from 1981 through
1995.
Cylinder bore was 91.9 mm (3.62 in) and stroke was 88.9 mm (3.5 in).

Initial output was 97 hp (72 kW) at 4800 rpm and 129 ft?lbf (174 N?m) at
2800 rpm.
By 1990 the 22R was producing 108 hp (81 kW) at 5000 rpm and 138 ft?lbf
(187
N?m) at 3400 rpm.

The first fuel injected 22R-E engines appeared in 1983.
Output of these engines is commonly rated at 105 hp (78 kW) at 4800 rpm
and
137 ft?lbf (185 N?m) at 2800 rpm.

In 1985, the engine was significantly reworked, output was up to 112 hp
(84
kW) at 4600 rpm and 142 ft?lbf (192 N?m) at 3400 rpm. Many parts from
the newer 22R-E are not compatible with those from the older pre-1985
engine.

The turbocharged 22R-TE (sold from 1986 through 1988) produced 135 hp
(101
kW) at 4800 rpm and 173 ft?lbf (234 N?m) at 2800 rpm.

However, its weakness is high-end power. Thus, most performance
enthusiasts usually prefer the Toyota 18R-G, 3T-G, 4A-GE and 3S-GE
4-cylinder engines, even though the 22R has a bigger displacement and a
strong block.

The engines are extremely well known for their durability, high gas
mileage and low to mid range torque.

Applications:

22R
1981 Toyota Corona
1981-1988 Toyota Hi-Lux
1982-1984 Toyota Celica
1981-1996 Toyota Pickup
1984 Toyota 4Runner
22R-E
1985-1995 Toyota Hi-Lux
1983-1985 Toyota Celica
1985-1995 Toyota Pickup
1985-1995 Toyota 4Runner
22R-TE
1986-1988 Toyota Hi-Lux, 135 hp (101 kW)
1987 Toyota 4Runner
