English Translation:

Is it possible to change components to obtain a 2 to 1 rod/stroke ratio in a d15 motor?

Do the rod lengths or the deck height cause a problem with this particular combination?

I believe that it's beneficial to have the rods as long as possible.

I need more information

thanks

PS: Dave, leave that poor donkey alone!!!

I think Smokey Yunick was a big proponent of 2:1+ R\S Ratios....but you gotta remember this was on a Big Inch V8, so even if the 2:1 Ratio shifted your torque curve super-high, you would still have plenty of useable torque at low RPM.

It's possible with major destroking and/or deckplate.

I was able to use a destroked D15b6 crank to the value of 80mm, and a 137mm LS rod to achieve a 1.7 rod ratio. Of course, the rod journals had to be enlarged to LS diameters, and the ls rods narrowed to a civic rod thickness.
By the way, the LS rods did not like high rpm and significant power, thus I had to upgrade in 2001.
