I would start with a 50 or 75 shot anyways to make sure the car takes it alright before going right to a 100 shot. You should upgrade your fuel pump for a 100 shot to be safe. People have done 100 shot on stock pump but it isn't recommended. People have also ran up to a 125 shot on stock tunes, but again if you can't monitor KR and such tht isn't a good thing to be doing a lot of. Maybe find someone locally around you to take out like 2* of timing or so.

Get TR6 spark plugs gapped at .035 too. Also make sure you have intake and cat-back exhaust so the car can breathe with the extra power increase.

I too recommend a new fuel pump, tune and start with a smaller shot to see how the car reacts then bump it up.

Don't forget to use the nitrous calculator too!

your 75 shot could be like a .044 jet (measured in thousandths).
according to the calculator, if you put in a 1.00 (one inch) jet, you would be putting over 38,000HP to the rear wheels. You might want to upgrade your injectors if you were going to shoot for a 38,000shot though.
