It's a motor from a toyota levin or trueno. It has 20 valves with VVT so it works like the honda VTEC, but starts after 4400 and adjusts the cams so you can go up to 7800 redline, peak HP is at 7400. The hondas start at 5500 I believe. This type of motor is also used in the Toyota Formula Atlantic Series, That version goes up to 12-16K rpm and 240HP N/A. Real nice if you have 15K to spend on it. But the motor was the most economical choice for me to swap into my car. There is not much demand for this motor besides those with older corollas (AE86) to use for drifting, I.E. Japanese cartoon called Initial D which feature's a trueno with the 20v. This motor is almost a direct drop in to my celica, bieng as the 4A-FE comes in my car I don't have to change motor mounts. Just some extension to the 20V wire harness. Which I have to modify anyway to use with my ECU.
