Toyota’s 4A-GE engine is a jewel of a powerplant. The 16-valve, 1.6-liter four-cylinder made its way into many of the brand’s performance-oriented products in the ‘80s like the Celica, MR2, and sporty trims of the Corolla. Drivers loved the high redline and adequate power for an engine of this size at the time. If you ever wanted to see the guts of one of these fantastic mills, a user on Reddit put together a stop-motion video of the complete assembly process.

According to his post, he collected the parts for this build for two years. The engine comes from a 1987 MR2, which has a stock output of 115 horsepower. This builder has some upgrades that should provide a nice boost, though. The block is bored out 0.02 inches (0.5 millimeters), and the oversized pistons have domed tops for a 10.4:1 compression ratio. There are also new cams and upgraded valve springs. “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,” the owner writes.

The resulting video is quite fun to watch. The soundtrack fits the engine’s era, and it’s always cool to see how things fit together. We especially love the custom paint on the oil pan. Most people would never see the part, but the driver can take pride knowing that it’s there. You get a glimpse of the MR2 this mill gets to power at the end of the clip, too. We wish the owner many miles of joy when this revvy roadster is done.
