Just curious what kind of vaccum I should see on my motor. It's a stock motor with 13b housings. Vaccum is -4.4. That doesn't sound to bad. My buddys fd with new motor was pulling -5. Shouldn't a larger motor pull more vaccum unless its a little worn? Also I was curious about my oil pressure. What should it be reading. My oil pressure sits at 3.5bar idling at 1500rpms when warmed up. Does that sound about right? Thanks.

Your oil pressure and vacuum sound good. I think the 20B pulls the same amount of vacuum though.

 

yeah mine doesnt pull anymore vacuum than anyother 13b

 

I think our NA pulls around 18 inches.
