In reading some of peoples comments here and reading the 911 engine rebuilt book im a little confused...I would like to built the "upgrading the 3.0sc engine" to his spec's...meaning the 964 cam and JE 9:8:1 pistons....but ive recently looked at je site and they dont make a 9:8 cr piston, and ive also heard that you can tweak here and tweak there to obtain this comp.ration...so does this mean you actually buy a lower comp/rat and tweak it to obtain this??? or do you have JE custom make you a 9:8 piston?? thanks---damian
