Actually, I'm pretty sure Sean is 3.8, when you're swapping liners and rods might as well add pistons and go bigger! I don't think he's posted much in the way of graphs yet, he's still tweaking and developing 
Edit: I'm wrong, 100mm pistons and not sure where that lands you with stock crank. Yup, looks like 100mm is stock! He did bump compression a bit.

I would run 10:1 only if E85 would be available in my area, I raised CR of my GTR from 9.0 to 9.5 and gained 30hp @stock boost (0.9bar), better spool etc...
I imagine that built engine with cams and valves that runs 10:1 CR is very powerful, I guess a similar setup on a stock engine with rods only would do 80-100whp less at the same boost

Hey guys
Iam installing turbos , the turbos are not even , one is sitting lower than the other , your kind support please . The right one looks higher, what do you think? Headers new . On my old headers and k24 , I had the same problem ( as I have been told when I installed my muffler ) is that normal ?
