open deck on the left closed deck on the right closed deck is a stronger block and can handle big power due to having less space around the bores if that makes sense

Thanks Craig. I would assume a std Wrx would be an open type and sti closed?

Surely though piston and rod quality would be the bigger deciding factor up to a point?

A well put together open deck block is good for 450 bhp anyway.
