feel free to add any. thought it was cool how with a different stroke and piston pin compression height nsx rods could be used. just widen the k series rod journal width to b series instead of the h/f series. And oem titanium connecting rods. what could be better?:dance:

not direct plug and play. for the nsx rods. but very doable. widening of the rod crank journal. and different compression height pistons.
the toda nsx stroker rods are same length as k24 but crank rod journals will have to be widened.

Excellent post! Back from the dead. :)

I can confirm the K24 center to center length for the rods. Checked it against my Manley catalog.
