more details, what rods/pistons? assuming you are using a metal HG/ARP?

I would go for high compression, but thats just my personal preference.. better for the street IMO..

Re: compression

higher compression will have better low head response, and yes the turbo will spool faster. However, it will be more prone to detonation.

With proper tuning you'll be fine either way. For most people, the 9.0:1 is a better choice for FI
