I am the original owner of a 92 S13 coupe with a KA24de motor I wanted to check the condition of the engine, so I had a leak-down compression check performed. It was rebuilt 6yrs ago and is mildly driven the results were 140, 140, 130, 145 the mechanic said the engine checked out to be in good shape with no issues but I've seen posted here on this site that say that the correct numbers should be around 175psi or slightly lower what do you guys think? Thank you all for your help.
