Compression Ratio


New Member
Hi guys and girls,

Below is my list of current purchased parts for my build which will be started pretty soon. My concern is the compression ratio I'm going to achieve with the selected Pistons/head gasket combo. I was told it should be fine and I should be able to throw some good boost in there however probably creating more lag than usual which I'm ok with. Can any of you pulsar gods shed any more light on this and if I'm going in the right direction.
Many Thanks
