turbo motor compression
turbo motor compression hey guys/gals...here is my situation
I'm picking up a 98Z from my buddy. The car has an LME built 347. I believe the compression is in the 11s...I think it is 11:1. To date the car has been a beast in NA forum. The car has run a best of 11.50 @ 118 with a 4l60 that was overshooting 3rd gear. The guys at LME said that the motor will handle a 200shot with no problem, and originally that was the plan, but I want to boost it.
I'm planning on doing a custom turbo set up, most likely I am going with dual 60-1s. I'm shooting for 600whp.
My question is this: Is this compression too much for turbo? Even in low boost?
My options are to just yank this motor and sell it as it is and build a new motor starting with a 6.0 block....or.....trying to lower the compression on this motor and boosting it.
Also, what can I do to lower the compression on the current motor without changing pistons out.
anybody have any suggestions? I appreciate any help in advance.

On pump gas, that is a bit too high compression. Get some heads with a 72cc chamber (317,035 LQ9/LQ4 or swap to the L92s w/L76mani) have them ported out a bit and use a thicker head gasket.
