I just did a compression test on my 92 B18A, and I got
195 195 185 200
are these good enough numbers for forced induction?

also, when doing a compression test does it matter if the enging is warm or cold? and does it matter how long you crank the enging?

 

To your question yes it matter if the negine is cold or hot. Try to do the compression on a motor thats avg heat temp. cranking also effect how the compression is.

IF you keep both consistent then you dont have nothing to worry about. By the numbers everything looks good.

 

Those are damn good numbers for a b18a that old.
