I would recommend doing turning after doing turbo. You won't get much out of while being N/A

 

With 136000 miles do you think that putting turbo on it will be worth it still. Everything is clean no leaks or anything

 

You could clean the block, sand blast it or walnut blast it. Get some piston and rods. Do any maintenance related things like timing chain anything that has worn out while you have the engine out.
As long the block is not crack, you should be good.
