Till today, I though that k series sleeves were made from the same material as the b series ones... I was wrong. A member of my site, posted this info that I think should be passed along

Please comment.

thanks,

cool stuff....

 

I did not see anywhere in the report where they mentioned the K Series. They did mention the S2000 (F20C). What am I missing?

 

s2000 was mentioned on the first page..

They do mention about the new accord (k24a) on the right column....

We need to have this confirmed by Golden Eagle or someone in the sleeve industry but it seems like K series blocks are NOT iron, they are MMC. Really hard to bore that material..they are hard as nails, hence why people pull them out and replace them with iron (read much cheaper/easier)

MMC" or metal matrix which incorporate amounts of silicon and carbide to improve or permit piston ring abrasion resistance however, machining of this type of material is difficult and expensive.

BAR’s engine partner Honda has produced an uprated power unit for its home grand prix at Suzuka this weekend.

The latest development of the RA004E V10 is believed to develop a staggering 960 HP, making it the most powerful engine in Formula 1. It uses advanced metal matrix composite (MMC) components to increase revs and consequently horsepower.

Honda’s F1 project leader Takeo Kiuchi believes the power output of F1 cars could exceed the magic 1,000 HP threshold next season.

“It’s within reach,” he told Autosport. “That level will not be easy - there are several difficulties to conquer first. But it could be possible.”

good info

 

Let me go out on a limb and say the K sleeves are not matrix metal. The reason I say this is that matrix metal blocks require a special piston also.

Several aftermarket piston manufacturers, CP for one, offer aftermarket pistons for the K but NOT the S2000. These pistons can be used with the stock K block. If the K was a fiber block, you could not use these pistons without re-sleeving the block. That fact would be noted in the piston catalog.

On the other hand, no off the shelf pistons available for the s2000 because of the material that piston would have to be made of.

 

so how do you add after market pistons to the f20c?

 

you sleeve it.

 

oh ok , whats the advantage to the stock sleeves ?

Thank you Earl...

I guess the "new accord" the article was referring to was the euro R one with the h22a type S motor....

IRON IT IS

What the advantage of aftermarket sleeves to stock sleeves?
You can run pistons.

 

i can run pistons in my d series with stock sleeves , im talking about why not with stcok f20c sleeves.

 

Cause the scratch the sleeves, I will see if I can find the link where someone posted pics.

 

IMO, the aftermarket companies should experiment with making pistons/rings compitable with the fiber-sleeves, not the other way around. Guess they are more interrested in sleeving blocks than spending thousands of dollars on R&D.

Wouldn't you do the same?

Everyone just re sleeves the H series fiber sleeve Prelude block with ductile iron ones and runs aftermarket pistons. The same thing is now being done with the S2000.
