You're going to buy the focus short block? Why?
It has stock components, so why would you do that?

If you're really going to cryo treat your engine components, just do it to your current components, and hone your cylinders and get a new set of rings. ( if you need it).

Waste of money IMHO.

Now, if you could get a slightly used SVT focus block, then there would be a block worth spending some money on. Stronger components, increased C/R, and oil squirters. But you're going to need a tune, and that will cost you approximately $400 just for the flasher. That doesn't include tuning costs, which will be more than $200. So, you're going to be spending at least $600 on just tuning.
