Hi

I have a erst s2 mfi, and its time to rebuild my engine, but i want to know if i really need forged pistons?

the spec will be :

-full mongoose exhaust
-standard cam
-standard head
-turbo T3 or hybrid T3
-actuator -31
- ahmed bayjoo chip
-big frount mount intercooler
-magnecor leads

to this spec i need forged pistons?
what is the standard compression ratio on a cvh 1.6 turbo?
