I'm still considering staying with 3.0. I have both the original 95mm SC cylinder and also 95mm Carrera cylinders (Kolbenschmidt). My local machine shop guy - who has been working with Porsche engines for a lifetime - does not really like the idea of a 98mm bore and a re-plate of the old Carrera cylinders. He strongly recommends a new complete C/P set which is mucho dineros.
Apparently, he's afraid os heating issues and reliability in stressed situations (track time etc).
What are your thoughts on that?
