Well ive been looking for engine specs for the K20 motor.. All i could find on H-T was the Bore and the Stroke (86 x 86).. but find some new measurements that we could pass around now...
http://www.speedvisionwc.com/c...S.pdf
Bore: 86 mm
Stroke: 86 mm
Rod Length: 139 mm (C to C)
Deck Height: 212 mm
Rod Stroke Ratio: 1.6162 ~ 1.62 R/S
Compression Ratio: 9.8:1, 11:1, 11.5:1

edit: more of the same info

-"K20 is 22 lbs lighter then the B18C"
-"The K20 again uses an open-deck, die-cast aluminum block with cast-in iron cylinder liners, but at the bottom of the crankcase, where the B18 used a sturdy main bearing girdle for bottom-end strength, the K20 does one better, integrating the main bearing caps into a crankcase extension. This "split crankcase" design is becoming the standard for new engines, as it delivers noise, vibration and harshness benefits as well as improved strength."

I was wondering if anyone has any pictures of the Engine?
Preferably, the Rotating Assembly. Inside the engine.
Head, Combustion Chambers would be nice too.
Thanks for anything.

That is not a finish hone on the sleeves. Check the fit between the sleeves. Just beautiful. Note the full girdle. This is the future.

yeah, K20's come with heavy timimg chains now...
DAMN&lt;look at that crank/block girdle..!

 

here's the JDM DC5 bible I scanned back in '01...

Just some misc K-series info..
Not only does the K-series have a timing change but it uses a roller-rocker arm assembly unlike the B-series, which use roller-pads and in norcal speak is 'hella' dope. The motor also turns in the correct way, clockwise, rather than counter-clockwise ala B-series.

The K camshafts are interchangeable with the S2000/F20C engine....actually I think, the whole S2000 head assembly is intercheangeable with a K20-S/R series.

 

wow..kewl...!

thanks Katman, and everyone.
