leave it as is
I'm installing my BT on my 1.8t very soon and Im running IE drop in rods with stock pistons. I believe the 1.8ts sit at 9:5:1 ratio now, Going to run around 25lbs of boost so I was thinking if it would be a great help or increase running a low compression head gasket? How much power will I see? I think its a .7 drop ratio gasket.
