Thoughts on a 225 rebuild

I don't understand why you would want to use the 198 rod and 2.2 turbo pistons. 198 rods are hard to find, then they would need "rebuilding"., and the pistons are still just a stock piston.
Just use a stock 225 rod, and piston. mill the block or head to get the CR in the range of 9.0 to 9.5 to 1, depending on what cam you run. We are talking a street engine, here. If you really want a "long rod" motor, do it right and get the Molner or K-1 rods and the Wiesco pistons.

By 198 rod, I'm referring to the length. I agree that the Molner rods would be the ones to source. As far as piston selection goes, unless you'll doing some wild things on the motor, why would you spend extra on a piston if the "stock" 2.2 turbo piston can handle it.

The reason for the change over isn't just for compression ratio increase as milling could handle this alone..your adding torque due to the longer rod and also improving the rod ratio which improves multiple areas on top of increase the compression ratio. This change would fall under the "Improve efficiency" category of motor building to use with add-on's such as intakes, cams, headers, etc.
