Have you thought about doing an actual compression test on this engine to see if it's higher/lower than stock or that of a 4g63t? It won't tell you your exact CR but it will tell you something.

I did the math using this calculator:

According to my numbers I got 8.0:1 to 8.1:1 CR on the 4g67, which is not bad for boost and considering the abuse that has been getting at @25+psi it seems to be accurate...
