Hey guys. I'm planning on Rallycrossing in my Focus soon, and I'm planning the upgrades to my motor so I can be a contender. If I completely build the head and then add a JRSC or Stage I or II turbocharger, would I have to build the block right away? I plan on building it in the long run, but if I can wait a little while, that'd be great.

This should be in the FI/Forum, but with proper fuel management your stock block should go pretty far...
