EM would only raise the cost of this project. I don't see a problem with running a thicker head gasket to lower the compression ratio and I'm sure I could polish the inlet/outlet of the head without an issue but if I screw up the PnP, I would have more money in it. I'm not sure I have the patience for that anyway.
I could also do surgery myself, if I learned how. But, I'm sure I would suck at that too.
If the engine takes a dump, I can get one from the pull-a-part for $300 or less. I thought the same thing about the Escort when I put the turbo on the stock engine at 160,000 miles. It now has 240,000 miles on it with a base-tune sent to me via email. I realize that is EM, but the stock injectors were maxed out with just some bolt-on's so I had no option.
