I am an Engineer who likes to rebuild engines as a hobby. Before I got a degree I was reconditioning cylinder heads in and engineering workshop.

I wish I had a resource like YouTube when I was building my first engine 25 years ago!

Hope this either encourages you to give it a go, or convinces you to get help from someone experienced to guide you through your first engine build.

There are many ways to skin a cat, but after building half a dozen Mitsubishi engines I thought I'd share some techniques and video of how I do it.

Enjoy!
