Anyone know S2000 rod lengths?
I'm looking for stock rod lengths for the 84mm S2000 crank 1998cc motor
Also the new 90.7mm crank 2157cc motor
I just cannot find these specs anywhere including the Helms manual
Thanks

Center line to center line of the small and big holes.
Why can't I find good tech info on the S2000 motor? No one seems to do internal modifications on them. Maybe it is because of those funky fiber cylinder walls they have. At Bensons, we replace them with the prelude style sleeves so they can be boosted on harder. However, we do at least 100 B blocks for every S2000

Thanks Mase, I have some of those stock units laying around also. That was going to be my last resort to answer my own question. I didn't think it was going to be this hard to find out.

Re: Anyone know S2000 rod lengths? (earl)
Well I finally got my answer. In case anyone cares, they are 5.984 in length.
That would give that motor a 1.81-1 rod stroke ratio. No wonder that motor rpm's so high. That is the biggest ratio I have ever seen.

<TABLE WIDTH="90%" CELLSPACING=0 CELLPADDING=0 ALIGN=CENTER><TR><TD>Quote, originally posted by devoid »</TD></TR><TR><TD CLASS="quote">that's for the 2.2..
the 2.0 is 6.023622047244094
</TD></TR></TABLE>Actually the 5.984 and the 6.023 are both available in the 2.0 engine, based on the height of the block. Apparently they had 2 blocks available with only a .04" height difference. I don't have a clue why.
If the 2.2 does have the the 5.984's also, they must have changed the pin height in the 2.2 piston.
Where did you get your info from?
