You can't look at a "estimated rod length" and stroke and say This engine can't make XXXXrpm reliably..Just doesn't work like that...

As it sits power production from fueling becomes an issue due to piston in cylinder speeds

we don't know the type of rod angles we're dealing with if it's working off of ej or fb architecture.....we don't know what kind of sideloads it'll have or if the pistons can deal with that type of constant G's due to lack of material etc etc etc
Of course, that's why I said we need to wait for more detailed specs. HomemadeWRX/3MI Racing already has rod specs apparently (but probably can't say), and may have offset already. However I'm just pointing out a few things about the engine that generally aren't good. The engine is very wide already so it can't really grow to accomodate longer rods or a more sophisticated valvetrain (no hope of variable lift or anything). At the same time we have a latest generation combustion chamber and fuel delivery design, which is nice.

I do believe in low levels of boost though.
