RalliSpec Race Spec Shortblock
So i'm going to purchase this block from Rallispec.com but need a little help choosing CR. I don't know if i should choose the 8.2:1 or the 9.4:1. Ive already got the cosworth ported heads ( Cosworth CNC Ported Cylinder Head Set w/ 20007395 Cams Subaru STI 2008-2015 20010140 at RallySportDirect.com ) but don't know what i should get. I'm kinda new into the boosted seen. I plan on running the Perrin rotated GTX3582R. while tracking the car id like to use VP race fuels C-10 mixture. If anyone has suggestions or pointers id like to hear them.
