I have the following and am running the stock fuel pump and injectors. It is a 98 WS6

LME ported FAST 90/90
230/234 595/585 114 +2 futral cam
TSP PRC 5.3 2.5R heads
FLP LT's w/catted y pipe
pulley

Will I be ok? What if I put a 100 shot of nitrous on it?

 

wet or dry? a better fuel pump is always good

 

i'm not sure yet

 

when you decide that we can talk about injectors

 

I have read other threads similar to this where multiple commented on their setups. It's seems to be hit or miss at around 400rwhp and over. Some people run their stock setups over 80%, some immediately upgraded, and others were right at 80% which is the recommended limit. Of you are planning on any future upgrades most people would say upgrade your system, if around 400rwhp is your limit then you could probably get away with the stock setup for a while unless you run WOT often. A good alternative for an upgrade with an occasional small nitrous hit would be upgrading to used 03-04 Cobra 39lb injectors with. Search for threads about this, they can be had for around $100 and you can make your own wiring adapters easily.
