Toyota Y engine

The Toyota Y engine is a series of overhead valve straight-four petrol engines that Toyota manufactured from 1982 through 1996, mostly used in commercial and off-road vehicles. The valve arrangement of the Toyota K engine is interchangeable with it. The 1Y is a 1.6 litre (1,626 cc) eight-valve unit with a bore and stroke of 86 mm by 70 mm and a reference output of 84 PS, and there is also a 1Y-J built to meet emission standards for light commercial vehicles. The 2Y has the same 86 mm bore and a longer 78 mm stroke for 1.8 litres (1,812 cc), with 2Y-J and 2Y-U variants for different emissions equipment. Applications include the HiAce truck, the first generation LiteAce, the ToyoAce and the TownAce.
