Hey folks I'm looking for some info and wanted to see if anyone might have it. Working with a RB25DET Neo and I need some factory engine internal specs: 
deck height
Cylinder bore
Piston stroke
Crank collar specs..
Honestly any factory internal specs for the engine. I'm going over it with a fine tooth comb to make sure it's a solid block before I start building it.

I have found a manual but it's in JapaneseNissan Skyline R33 Service Manual.pdf

You won't need a crank collar unless the crank is damaged. Bore and stroke here:

There is only one set of specs on the wikipedia page for RB25DET Neo. Hardly matters. All RB25s have the same bore and stroke anyway.
