AKWIKZ Posted November 26, 2006 Share Posted November 26, 2006 Guys, I am looking for a way to get a higher C/R using pistons I have already ordered. I had planned to build 2 RB30's, one turbo and one N/A. I am now looking to build just the N/A. The problem is that I already ordered a set of 9:1 C/R pistons. I want to get closer to 11:1. The calculated head gasket thickness is 1.2mm. I can get 1mm or even .8mm to start with. The combustion chamber of the RB26 head is 66.5cc. How can I safely get more compression without having to buy new pistons? CAn I get away with decking the head? Or possibly the block? Thanks Brian Quote Link to comment Share on other sites More sharing options...
greenmonster80 Posted November 29, 2006 Share Posted November 29, 2006 I have never looked at doing this but I would look at decking the block if the headgasket change won't give you enough of a drop. That way the head is still capable of future mods if needed. Quote Link to comment Share on other sites More sharing options...
