So i picked up a d16z6 engine and trans to build and swap into my ek hatch and i took it apart today. I found what looks to be small cracking in the bottom end and wanted to see if it was just normal wear or something that would prevent me from running this block. I plan on boosting this build so any input would be appreciated.

 

What you have pictured appears to be normal and as cast from the factory... not cracks at all.

 

Okay thank you that’s what I was thinking but i’m new to this so just wanted some feedback.

 

Looks like someone clearanced the bottom of the cylinders for H beam rods.
