New pistons or shorter rods are the best way to lower compression.
You'd be surprised how much power you can make a .5 bar and 10:1 CR.
BMW runs 10.2:1 CR on the production N54 and N55 motors with .6+ bar boost.
Dinan cranks the boost up to .95 bar and gets 400+ HP and 440+ torque.
Most important, regardless of CR is that you have optimum control of your AFR's and ignition if you are looking at very high boost.

Hi Ed,
The rods are about as short as they can go without hitting the crank, they are 143mm h-beam type ment for a honda.
400hp is what I would like to see out of this project, if that can be achieved with 10.1 cr I'd be happy.
I've got an emerald standalone ecu for the engine management, with a ford edis6 coil pack setup to give a decent spark.
