It's time for a new episode of Project Underdog. Today we tear into the 4AFE engine to see what's it like inside and to prepare it for machining. The future of this humble 1.6 liter from the 90s looks interesting as it will be turbocharged to 300 hp and then installed into my Toyota MR2 mk1.

This engine teardown is more than that, because we will also be analyzing some design aspects of the 4AFE, inevitably comparing it a bit to the more famous 4AGE engine and we will also do a bit of engine forensics to see what kind of life the engine has lead so far. I tried to keep this video relaxing and even a bit ASMR -ish, don't know it worked - let me know if it did :)

We start the engine disassembly by removing the intake manifold and opening it up to see inside. This is followed up by the removal of the exhaust manifold. The valve covers come off next, followed by the distributor and camshafts. Next comes off the cylinder head and we finish things off by removing the pistons, connecting rods and the crankshaft. Along the way we see if this engine was take care of and we also discover some peculiarities.

A special thank you to my patrons:
