lowering compression

[fukenricen]

Here is what i would recommend didnt read all the replys but if you want to lower it then do it right and purchase a cometic headgasket they have thick ones and even spacer ones to help you lower it but were talking about dramatic lowering aswell. to tell you the truth i wouldnt lower it to much or you will be driving a lag slug. What compression are you at right now?

9:3:1

What are you currently using to get to 9.3:1?

I'd say that's a good place to be for boost. Response will be great, just have to make sure the tune is good.

lol if youre going to do something, do it right. Don't cheap out and just buy a head gasket, lower compression with the pistons.
