Is it possible? I saw that there is a difference in metal. I have a decent n/a but a good turbo gasket in great shape. I wanted to know if I could use it.

 

The turbo exhaust gasket is designed to handle high pressures and temperatures. You can use it on an NA if you wish. If you use the NA gasket on a turbo car, it will eventually blow out.

Edit...But the emissions passages are different which may be a concern if you need to pass.

 

just buy another n/a gasket they are quite cheap
