I have had my B13 on the track many times. I note that you have a B14 but what I am about to share should apply to your chassis as well.
I usually follow advice that I found here on the Forum to run roughly 38psi front and 35psi rear HOT pressures when the car comes off the track. Optimal pressure will depend on the tires and the car, as well as the track and the driver, but this is the general area you should be in.
I monitor the interface between the tread and the sidewalls to watch for excessive rolling over and generally found that these pressures are in the ballpark for my car and driving. Most performance tires have several little ">" marks on the sidewall pointing to the outer circumference of the tire near the tread interface. If you have these marks, you can see if you are running over them after you come off the track from your first run. If you are, then you might add a few psi to that wheel and see if it helps. Some drivers use a little white shoe polish or chalk to help monitor tire rollover. I find it easy enough to see what's going on without the visual aid.
Another observation that I have made is that starting at the Nissan COLD tire pressure recommendations (33 front and 29 rear) usually causes me to come back into the pits after my first run with HOT pressures greater than 38/35, especially in the front, where all the action is on our cars.
So, for your application, I would recommend starting ar 33/29. Then visually check your tires for roll over after each run. Also check your HOT pressures right after coming off the track with an eye toward possibly letting some air out of your front tires if it seems appropriate.
Following this approach should keep you safe from a tire pressure perspective and let you focus on learning to drive the car.
Have fun and be safe.
