what kind of slugs are better for turbo engines dished domed or flat

 

You'll find that when you choose the pistons with the compression ratio you want, you wont have a choice. That's how they make different compression ratio pistons, by dishing them, doming, etc.... Just figure out what size pistons you want, and what compression ratio, and order.

 

Depends on how good of a tuning system you have, and how well you can tune really. I'd say go with some high 9's low 10's c/r if you can tune good. But most people run 9.0-9.5c/r flat tops on boosted engines. Just dont drop into the 8's!
