08u rb25de with rb30e pistons?

[Mr cooper]

Hello people. I have a couple of engines sitting around and I would like to know if putting rb30e pistons in a 08u engine will fit and lower the cr

I have done some research and only found people doing rb30de builds with 25 pistons. But they have to mil the block 1mm aparntly. 

Hope someone can clear this up for me cheers.

Slightly different pin Heights may make the piston sit proud of the block

dam I thought that could of been a issue. Do you know if r33 25det pistons fit ?
