those are replacement sleeves you notice how they still have the aluminum outter liner on them? i am pretty sure all aftermarket sleeves are full ductile iron without any aluminum, and those look pretty thick actually more so than stock iron liners so the might be good for 500+whp

 

THose are DARTON Sleaves for a D Series, i have been told they hold a good amount of boost, my friend is making 300whp on them, they are alot thicker then stock.
His Looks just like yours

If they are stockers I sure as hell wouldnt put more than 14psi......now here comes the H-Tech wrath about how everybody does it....

I will say those look nothing like my dartons, mine look much thicker and were not shiny like that

 

hold boost?

psi has nothing to do with it and is irrelevant

 

what kind of pistons are those?

 

my darton sleeves didn't look like that, those look like honda sleeves to me.

 

If those are stock sleeves, then my b18a sleeves are made in china, not japan!!! Those are aftermarket, look at how much thicker the iron sleeve is, the stock sleeves are much thinner. In fact, the iron too aluminum ratio on a stock sleeve is about the same, these have almost no aluminum at all. Aftermarket

Whether or not they are darton is no matter, they are much thicker than stock.

 

look like iron liners and not full sleeve replacements...but as im not a metallurgist...its simply my uneducated opinion

 

These are darton sleeves that have been bored out .5mm, look much thicker than those shiny things above.

 

either way, the sleeves he has, look thicker than stock. But you sleeves are much larger!
