Depends if you're going turbo or not. If you're not going forced induction a CR of 8.5:1 will lose you loads of power.
If you're going forced induction they look spot on  though it depends on whether the bore will need enlarging / honing... It says in the add
they have three sizes of pistons (presumably to compensate for small bore changes during engineering work)...

thats a nice deal! 8:5:1 doesnt mean laggy if you having a corect turbo.Fit GT28 and its gonna pull like train in all rpm and in any gear!

If you haven't decided on an ECU yet the guys at OEMX have done a lot of dev work with the Rotrex on a Duratec. They are also working with inlet
restrictors to shape the power delivery to suit your needs.
Also don't lower the CR of your engine too much as the Rotrex works very well with high CR.
