Just to be safe, you should probably upgrade your fuel pump. Even getting the somewhat pricey Nippon Denso (rx7.com, SR motorsports, other places) fuel pump is only about $250. And it's a direct drop-in replacement. Just consider it extra insurance.

With your mods no problem at all.Remember your only above the factory specs by a 1lb or two of boost
Always run the highest octane gas you can find.Plenty of guys run 13lbs on the street all the time
without problems.14lbs.seems to be the magic # not because of the apex seals or eng.but
because of the fuel system and injector duty cycle which becomes maxed out. With proper fuel and
tuning stock apex seals can be good for 16-17 lbs boost
