Yes, it does have internals, and Tripoint sells all of them, from what I gather. They were selling a set of rods for the WSC Protege here. I can't remember the make... Perhaps Eagle rods? Dunno. Anyway, they also have custom pistons running 13:1 or so compression, and the wrist pin was pushed up into the piston as far as it could go to allow for a much better rod ratio. Ask SpicyMcHaggis; His P5 has a head done up by Tripoint, and he's talked with them a lot about the amount of N/A power they're pushing, and what it's taken.
