i have a built ls motor and am getting rc precision 310cc fuel injectors installed on monday. i was wondering if i need to upgrade my fuel pump or my stock ls one will be ok for my setup. one more question is that i was reading posts and i saw a discussion on rev limiters and how hitting they are set for a reason and hitting them can and will cause damage. well i was wondering since my stock redline is 6800 and i'm upping my redline to 8000rpm if going past 6800 which was my revlimiter would cause any damage? thanks for your help once again.
