Toyota 2.7-Liter Specifications

by Justin Cupler

Toyota's 2.7-liter engine is one prolific powerplant: It has been in production since 1995 and was still in production as of the 2011 model year. There have been two variations of this motor. It was first used as an option in 1995 Tacoma; it continues as an option on the truck through 2011. It was also used in the 4Runner from 1996 through 2000 and the Highlander from 2009 through 2011.

Configuration

Both versions of the 2.7-liter were inline-four-cylinder (I-4) engines. They had 16 valves -- four valves per cylinder -- operated by double-overhead-cams. This meant that there were two camshafts that sat on top of the cylinder head.

Internals

The basic internals of the 2.7-liter -- in the Tacoma and 4Runner -- remained unchanged from 1995 through 2011. The 2.7-liter had a bore of 3.74 inches and a stroke of 3.74 inches, making it a "square" cylinder bore. The overall displacement was 2,694cc. The one component that did have a small change was the compression ratio; it was 9.5:1 from 1995 through 2004 and was increased to 9.6:1 from 2005 through 2011. The Highlander version of the 2.7-liter is a little different. It had a bore of 3.54 inches and a stroke of 4.13. The engine's total displacement was 2,672cc; it had a 10:1 compression ratio.

Horsepower

The 2.7-liter Toyota engine has seen a few variances in horsepower output over its production life. From 1995 through 2004, this engine produced 150 horsepower at 4,800 rpm. In 2005, it saw an increase to 164 hp at 5,200 rpm. From 2006 through 2011 -- in the Tacoma pickup -- it produced 159 hp at 5,200 rpm. In the Toyota Highlander -- from 2009 through 2011 -- it produced 187 hp at 5,800 rpm.

Torque

Just as with the horsepower, the torque varied slightly from year to year. From 1995 through 2004, this engine produced 177 pound-feet of torque at 4,000 rpm. There was an increase in 2005 to 183 pound-feet at 3,800 rpm. From 2006 through 2011 the 2.7-liter -- in the Tacoma pickup -- produced 180 pound-feet at 3,800 rpm. The Toyota Highlander -- with its different version of the 2.7 liter -- produced 186 pound-feet 4,100 rpm, from 2009 through 2011.
