I’ve searched in this forum but haven’t really been able to answer my questions. I’m building an ls/vtec right now and I’m considering adding a 50 or 75 shot to it once it’s completed(14’s would be nice but 13’s would be oh-so-sweet). If I do decide to do it, I want to make sure that the engine can handle it. The car will have around 170-180whp when I’m done with it without the nitrous. My main concern is that I was planning to use shotpeened LS rods and stock b16a valves. I know the rods could handle the extra power of just the ls/vtec, but with even a 50 shot on top of the 170whp I am worried they wouldn’t hold up. And I’m not sure if the valves would hold up either or if the compression is too high. And I think I’ll also need to mess with my fuel system like new pump, injectors, etc, since I’m going to be running 11:1 compression.
So basically the more research I do on nitrous oxide the more expensive I find it is. Here’s a list of everything I could think of so far to safe guard my engine and rough prices. Please let me know if you think a price is too high or too low or if something I listed is unnecessary or if I forgot something. And the nitrous will only be used on the strip(ok maybe once or twice on the street just for a smile).
stainless steel valves ~ $300
Eagle rods ~ $350
VAFC(or similar fuel controller) ~ $300
colder spark plugs ~ $40
bigger injectors ~ $350 (didn’t I hear somewhere that prelude injectors will work and are a good upgrade?)
adjustable FPR ~ $120
A/F, temp, etc. gauges ~ $150
2-3 hours on the dyno ~ $200
and of course the kit itself ~ $500
BTW, are there any nitrous kits out there that come with a lot of the stuff I listed above? Like the spark plugs, injectors, fuel pumps, gauges, FPR, etc…??
