3RotorRocket

Im sending my car away this winter to get a turn key job done.I don't have the time or tools to do it myself.I really want to but can't because im working so much and have a little daughter to look after now.All my time is taken.Anyway im getting these engine options done.3mm apex seal upgrade,corner seal spring upgrade,rotor housing cooling modification,polished rotors and maybe ceramic coated also.
What are the best apex seals to use when running nitrous?Im stuck as to what porting to get.I am deciding from these three port jobs.Street port (Extreme),Half bridge port and Full bridge port.This car will not be driven daily and won't see the road much.
