My 03 Evo hasn't ran in two years. It was taken apart to install a larger turbo setup, but due to personal issues, it was never completed, and I am currently returning it to (stock with minor bolt-ons). Are there any precautions I should take prior to turning the engine over?

To start. Ide make sure the oil and filter are fresh. Check/change the spark plugs. Drain the tank and put some fresh gas, or maybe a fuel stabilizer. Pull the fuel pump fuse and crank the engine for a bit to get the oil circulating before starting it up for the first time.

All i can think of off the top of my head.

I would be cautious and also change the transmission and transfer case fluids as well as the rear diff fluid. These fluids need to be replaced on a regular basis anyways for good maintenance of an Evo and right now would be a great time to start with all fresh and new fluids. Other then that I think biggiesacks covered it.

yes do plugs. my friend didnt start his for over a year and a half and he drove and had bad misfiring. we found the 3rd plug blown out stripping the threads. so yeah change them it wasnt worth the trouble lol

Is it necessary to drain the fuel tank when there's less than a quarter tank? I was planning on adding 5 gals of fresh gas.

Stripped the threads for the plug in the head? If so yikes, that's a huge fear of mine, hence why I use a lot of antiseize with new plugs every time lol

Absolutely! I consider fuel that's been sitting for 3 months old.

Definitely change the plugs, fluids, etc. I'd clean the injectors and check fuel pressure as an inexpensive precaution regardless of it sitting.

I'd log while it was at idle and if it looks good then take it on a cruise while logging. If everything checks out get it tuned (I'm assuming it needs a tune due to new turbo).

Just run a hot wire to the fuel pump and then put the return line in a bucket. Pump all the old gas out, reconnect the return line and start with a fresh tank of gas. Sounds hard, its not.

I left a 1/3 tank of gas in mine for years and the tank rusted and clogged every pump filter I put in. I dropped the tank and put a 16gal cell in the trunk. Sitting gas turns into water causing this.

Yikes, was the car sitting outside for all that time I assume? Just wondering.

Hope that doesn't happen to me.

sitting gas does not turn into water. It is the temperature change with the humidity that will cause condensation build up in the take which with enough accumulation with cause water to be in the tank.

You're right. I could see my gas tank rusting if it was sitting outside in the elements for 2 years. Fortunately that's not my case, it has been in an underground garage this whole time, but I am definitely going to drain it prior to starting it.

Timing belt should be examined and possibly replaced if it is dried and rotten, along with a new tensioner and water pump. Accessory belt as well.
