This is a B18a1 block I recently purchased from a friend. I took the head off to check the condition of the cylinder walls and need to figure out what type/compression these pistons are. Please disregard all the crud in cylinder #2 and #3, they will be clean prior to installation.

Here's a picture of the block:

Did you clean them or is that a coating?

Judging from the valve reliefs, look like they could be 9:1 CP's

I didnt clean them, all I did was just removed the head. Thanks for the quick replys!!

Ask your friend ?

look like ~9:1 compression, if u want to know the brand for sure remove the oil pan and windage tray and look at the underside of them

eg:R

look like old gen. cp's 9:1

looks like someone didnt want to plane the head for that motor and used crappy rtv instead?

they look like the 9:1 CP's that i had for my GSR....except mine were shiny

if they are 9:1 cp pistons, then they should be paired with some aftermarket rods correct? Will removing my oil pan help me see if I have aftermarket rods and rod bolts?
