OT, Shaun, and a couple of STI (one EVO) guys seem to agree that dropping to 9:1 is a good medium for our engines. It will only decrease the stock 230bhp by ~4% (or ~9bhp) and I probably will not notice since the block will be bored, have head work, etc to improve flow.

This compression what what I will choose on my EZ30R going in my Impreza when I turbo it later down the road for the same reason. Though I have my mind set on a single GT40R twinscroll with a light hot side to spool somewhere in the 4-4.5Krpm range to have it when I want but not have to boost all day. I'd love to twin turbo a second SVX if I got one as I'd like to leave this one as an NA build so I'll be eager to see how you route things and what does/doesnt' work. GOOD LUCK!
