Here’s a stop motion time lapse video of a full assembly of the Toyota 4AGE 16v engine, as found in the ae86 trueno levin corolla, toyota mr2 aw11, as well as other toyota vechicles like the corona, sprinter, carina, and even the Chevrolet Nova and Geo Prizm.
This video and engine is a product of two years of collecting parts, learning things I previously knew nothing about, saving money and then finally putting it all together.
The 4age is a sporty 1600cc 124hp (116 with cat) 4 cylinder engine with a 7600 rpm redline and is one of the best sounding 4 cylinders out there. It’s a simple and reliable yet entertaining and exciting engine that loves to be revved and driven hard. By today’s standards its under-powered and outdated but it still has a faithful following due to its great character. It is also what Initial D protagonist Takumi Fujiwawa has in his famous ae86.
The particular engine assembled in this video is a 4age 16v bigport from my 1987 MR2 mk1. The engine has been lightly modded with some technotoytuning adjustable cam pulleys, HKS valve springs, mild catcams camshafts (2x 7105136 exhaust cams, with 8.0mm of lift and 244 degress of duration). It also has domed 4age smallport pistons and a very mild head and block cut, leading to a final compression ratio of about 10.4:1. The block has been bored 0.5mm and oversized cast pistons and rings fitted.
This is a street build and goal was to give the engine a small increase in power and make the engine more lively and exciting, but also keep it as reliable as possible. This is why the engine has remained non-interference. The crankshaft, flywheel, clutch pressure plate, pistons and conrods have all been balanced to ensure the engine revs as smooth as possible and copes well with high-rpm.

Crank bearings: OEM
