Toyota made many changes to the 22R in 1985, often referred to as a Late 22R. Deck height of the block was decreased to 11.062 (281mm). The decrease in height is only 14mm so it can at times be difficult to spot the difference between the early and late blocks even when side by side. The single roller timing set up remained but the shorter block required shorter guides and timing chain. The links on the timing chain were reduced from 98 links to 96 links. Many other changes were made and Toyota stuck with the design from 1985 thru to the end of production in1995. The E seen on the end of the engine classification signifies that the engine has electronic fuel injection instead of being carbureted.

The block is hot tanked, surfaced, and torque plate bored and honed. Head bolt holes are tapped out to ensure proper torque readings. New freeze plugs installed. Crankshaft is turned to next size. Crank is installed with TaiHo(O.E.M.) bearings. Connecting rods are re-sized on large end, cleaned, honed, re-bushed with new pistons and pins. All bearing clearances are measured and documented on a build sheet. Ring end gaps are all checked and recorded. Rebuilt engine w/out head, includes timing cover that was surfaced with the block.
Longblock
Our rebuilt Toyota 22R and 22RE engines have the block hot tanked, surfaced, and torque plate bored and honed. Head bolt holes are tapped out to ensure proper torque readings. New freeze plugs installed. Crankshaft is turned to next size. Crank is installed with TaiHo(O.E.M.) bearings. Connecting rods re-sized on large end, cleaned, honed, re-bushed with new pistons and pins. All bearing clearances are measured and documented on a build sheet. Ring end gaps are all checked and recorded. Installed timing set is O.S.K.(what Toyota uses). Includes new timing chain, tensioner, sprockets, and guides. Japanese head gasket with new head bolts. Head is a new casting, new valve guides, new valve seats, OSVAT valves and polished stock camshaft. Rocker shafts and arms are replaced with new arms and shafts. Oil pump is new Aisin(O.E.M.) with oil clearances checked and documented. *Now all 22R/RE Long Block engines come with an OEM Aisin water pump installed.
