Type 9's don't last long on the 24V if used hard.
Main and big end bearings are one bad point, the can go anytime after 100,000. I did a set at Donny on a 100,000mile BOA. BOA chain guide is another thing that goes, not a ford part anymore. BOB is better as it has 2 guides and these are still a ford part.

If i were to build another car up it would be Zetec turbo RWD. Oh and that would go in an Escort or Sierra
