The Toyota GR engine family is a V6 piston engine series. The GR series has a 60° aluminum block and aluminum DOHC cylinder heads. Some versions use MFI fuel injection, some have direct gasoline injection, and some have a combination of direct injection and MFI. This engine series also has 4 valves per cylinder, features forged steel connecting rods, one-piece cast camshafts, and a cast aluminum lower intake manifold.

Note: Horsepower ratings have changed due to SAE measurement changes.

[edit] 2GR-FE

The 2GR-FE is a 3.5 L (3456 cc) version. Bore remains at 94 mm but stroke is reduced to 83 mm. Output is 268 hp (200 kW) at 6200 rpm with 248 ft.lbf (336 Nm) of torque at 4700 rpm. This version features Toyota's "dual-VVT-i", variable valve timing on both the intake and exhaust cams.

Applications:

[edit] 2GR-FSE

The 2GR-FSE engine used in the 2006 Lexus IS 350 incorporates Toyota's D4-S twin injection system. This system combines gasoline direct injection with traditional port injection. Using direct injection and port injection simultaneously facilitates more precise mixing of air and fuel under low and medium load conditions for greater efficiency, while high load conditions dictate the use of direct injection alone for maximum power. The 2GR-FSE engine is rated at 315 hp (232 kW) at 6400 rpm and 377 N·m (277 ft·lbf) at 4800 rpm. The 2GR-FSE has also been slated for possible use in the upcoming 2008 Toyota Supra (which is to be released October 2007) but tuned to the output of 350 hp (261 kW) at 7000 rpm and 290 ft·lbf (393 N·m) at 5000 rpm.

The 2GR-FSE was on the Ward's 10 Best Engines list for 2006 and 2007.

Applications:

[edit] 3GR-FE

The 3GR-FE is a 3.0 L (2994 cc) version with dual VVT-i. Bore is 87.5 mm while stroke is shared with the 2GR at 83 mm.

Applications:

[edit] 3GR-FSE

The 3GR-FSE used in the 2006 Toyota Mark X adds gasoline direct injection(Its name is "D-4") engine.

Applications:

[edit] 4GR-FSE
