invest in your tuning (no cheaping out here with a fmu), keep the hp to a reasonable amount (200-220whp) on stock internals, forged you can run a lot more. I've run as high as 10.2:1 compression and boost just fine, i've seen people run upwards of 11:1 compression (street cars) with boost. itr's love to make tons of power with a mild turbo set-up and their compression is on the high side.
IMO for a street car 9.5:1 up to about 10.6:1 compression is perfect, run lower then that if you plan to run lots of boost and make lots of power.
