Does your 22RE need to be freshened up Check out the Evergreen Toyota 2.4L SOHC Enigne Rebuild Kit. The differences between 3VZ-E and 3VZ-FE are the new DOHC heads with two camshafts for each. Many that drove this engine say that it was the best Toyota every built, despite the fact that it was not an overpowering engine. I'm going to test mine this weekend and would have likely not thought about it and assumed the engine was screwed. In 1992, the production of a more modern 3VZ-FE engine has started.
Thank you SO much for the reminder about altitude affecting pressure. Note: Other manufacturers may modify the engine after it has left the Toyota. The company follows a naming system for their engines: The suffix (separated by a dash) specifies the features of the engine: After 2000 indicates E85 Ethanol fuel. Here in front range Colorado, at 5000 feet, 125-135 psi is typical of a good engine. Toyota has produced a wide variety of automobile engines, including four-cylinder and V6 engines. If you don't do the test exactly as the FSM specifies, you'll get different results.Īlso note that the target compression numbers drop by about 4-5% per thousand feet of elevation, since there's less air to compress at higher altitudes.
What the low compression calculator does is to find out what the 15 difference compression value is from the highest compression value you got. The number in the factory service specs is empirically determined by testing a known good engine under a specific set of conditions. If a compression value varies by more than 15 of the highest compression value, then that engine cylinder will cause a misfire and/or rough idle. Finally, throttle opening determines to some degree how much air gets pulled in during the test and will also affect the numbers.īottom line, it's very difficult to compute the proper value. From 1989 to 1995, Toyota made the engine a little more powerful.
#COMPRESSION SPECS FOR 1992 TOYOTA 3L ENGINE SERIES#
The M Series engine was built into most of the Toyota six-cylinder vehicles produced during its. The 7M-GE launched in 1986 in the MA-70 Supra and was the only M Series with a four-valve cylinder head. The compression of the engine was 9.3 to 1, with an bore of 92 mm and a stroke of 89 mm. The 7M-GE engine was the last of the M Series, produced for top-of-the-line Toyotas from the 1960s to the 1990s. The maximum torque reached 137 at 2800 rpm. All of this stuff has more or less effect depending on cranking speed. From 1985 to 1988, the 22RE was produced with a maximum output of 105 horsepower at 4800 rpm. It also gets modified by how fast the compressed air dumps heat to the cylinder walls, and by valve timing. However, that gets modified by the adiabatic constant of the intake charge, which changes with air fuel mixture. To a first approximation, the pressure should be equal to the (compression ratio -1) times the local atmospheric pressure. Keep in mind that there is nothing precision about the normal compression test on an engine.
