Interested in this project as I am also building a cheap zetec turbo to lump in the Orion for a time pass...but I'm keeping it bone stock 1.8 and not running big boost...even if I see 150-160hp ill be more than happy...anything more than the 1.3OHV engine can currently churn out will be a bonus!

Do you have the Finish/part number for the thicker head gaskets? I was contemplating going down this route, but I haven't looked into it too much...one thing you have reminded me on though is to buy a new timing belt kit and water pump just for the sake of doing it!
