[GnArKiLl]

what is the stock compresion ratio i was told it was 8:5:1 then 8:0:1 then somthin else but i forgot.... so what is it?

[DSM_421]

For a 1g or 2g?

Edit - I will go ahead and just tell you both...

2G turbo pistons are a higher compression ratio than 1G turbo pistons

8.5:1 instead of 7.8:1
