When buying pistons, how do I know what size I need? I hear people saying they need .20 over bore or something.

 

If your block was over bore you would know since you would have sent it out to a machine shop to have that work done.

 

i've read about those. if you went overbore then get overbored pistons. what exactly is your question, cause i would like to get informed myself. like, do you need them for a certain block? be a little more specific. the shape, size, wieght, those have always something to do with compression

 

Well, I just want to lower my compression in my b16.

very informative

i'd say get thinner gasket. i haven't came across threads wanting help o lowering compressions. it'll be good to know.

yeah. lols. that's what i meant, "thicker" not "thinner".

To lower the comp you need a thicker head gasket or lower comp pistons.
We can also lower the comp by massaging the chambers too.

 

i hear inlinepro makes a thicker head gasket that is good if your looking to lower your comp
