im gonna be building a b16 or maybe d16 but is sleeving a must if pushing 20-25 psi. I'm obviously putting pistons and rods in but don't know if I need sleeves. I can't find any info on sleeving a block so if someone can help out that would be great. Also if anyone has the link to the b16 turbo thread can you please post that, I can't find it since I don't know the title. Thanks

 

its been done without sleeves.

thanks for the info. if just installing pistons and rods what should i do before that, just get it honed to clean it up and make sure it's a smooth surface.
