I have the japnz translated engine manual for the r33 skyline motors, to include the 25 and 26, and was just wondering if the info for the bottom end was the same. I am wanting to rebuild the bottom end, but need the clearances and torque specs, and engine component specs. the manual covers the 26, but doesn't get into the internals (block or head) of the 25. I was hoping that info was the same, which is why they didn't cover it.

The r33 jpnz manual does have the Torque specs for the head. The r32 manual has the specs for the head and bottom for the Rb25de. I would use those.

it has torque specs for the head, but nothing on the internals of the head, ie the valve sizes etc.
