Are you running an R32 or an R33 RB25DE ? I'm not sure about the internals of the R32 block. The R33 DE crank and rods are the same as the DET. The pistons have a hair larger dome, and are not really strong enough to support a lot of boost. The DE heads have a slightly smaller combustion chamber, but are otherwise identical to the DET. DE compression ration is 10:1 as you know, but that is fine for a turbo car that is well tuned. Most people reduce compression ratios for ease of tunning, and to reduce the risk of detonation. Detonation kills, but with proper tunning higher compression makes a ton of power.
