Hi guys,

2014 Nismo 370z here with 34k miles. I’ve been contemplating selling it for a while and think I’ll just hold on to it for now. Still having a lot of fun with it. I figured if I’m keeping it then I want to do a compression and leak down test. I don’t have a service manual so I’m not sure what psi range the compression should be aside from the universal rule that all cylinders should be within 10% of each other. What is the range I should be shooting for?

For leak down I’m hoping for 7% or less. It’ll be real interesting to see what numbers I get!

Thanks in advance
