In the case of the OP. Your'e absolutely right. 9.5:1 ratio is not that high. It's actually my preffered CR so it not to lazy off boost. We just got to finish the same setup I sold to a friend running a reflashed S13 KA24DE ECU.

While it may not be significant in regards to the OP setup. Having high comp does assist on faster spooling a larger turbine turbo. My KA-T is on 11:1, E85 and Holset..

If your'e just refering to CR between 8-9.5 all you need is a solid tune on the best pump gas you can get 91-93.

You should be fine putting a turbo on an NA SR, a 9.5:1 CR is generally considered to be at the upper limit of conservative.

Agreed..
Here's a pic for the OP...
