Hondata

I am planning on purchasing the hondata upgrade package for the JRSCand eventually increasing the boost. It's going on a D16Y8 from an EX and I was curious to see if there are others on this forum that have increased the boost from the standard 6psi. What I'd like to know is whether or not the stock block and pistons are going to be able to handle the additional boost to 8psi and beyond or am I going to have to get work done on the internals? Does anyone else have any experience in tuning the D-series? Thanks for any input you might have.
