Do a bit of reading there. ZBum's site has the stock info, whereas redz31.net has the modifications info. Both are worth the time to read.

Oh, and redz31.net used to be redz31.com... the old domain name expired and Jason (site owner) wasn't able to renew it for whatever reason. So if any of the links don't work, just replace the ".com" with a ".net". You may or may not have to do this, I'm not sure how far he has gotten with changing these links. And I sure as hell aren't going to go through all the links to check for you.

But to find the answer to your question, go to ZBum's site and click on "Z31 Information". Look around for something about the turbos specifically... click "Basic Z31 Information" and look in there. Well, nothing on what boost levels there are, but there were apparently "three" different turbos on the car. Go back to the last page. There is a link called "Differences", so you click that since there were different turbos. Amazingly, the info you seek is in the first four lines of that page. Just find your year car (85) and look at the stock boost (6.7psi).http://www.az-zbum.com/informa...shtml

^That's pretty much how that site works though.
