I have a NX wet kit and was wondering why they tell me not to run a 75 shot on a LS motor. They said the fuel pump couldn't handle the load of all that fuel (from the nozzle and my fuel regulator. Now I know that if not enough fuel is getting in there then it will lean out. I have heard a lot of people running 75 shots in there honda's and just wondering is it that bad to run a 75 shot instead of a 50 shot. Also what plugs can I get that are colder than the stock ngk's (non platunm).

any help?

 

Search the forced induction forum.

 

anything higher than a 65 shot u should upgrade fuel pump to 190 or even a 255 for future mods. I would also upgrade to some bigger injectors maybe 270 or 310's as the stock 240 would be border line. u can get some ngk racing plugs.

 

i used to do 75 in my GSR, no problem. i had Zex dry kit, 75 shot, -4 degree timing(about 12-14) and NGK ZFR7F-11(<--- these are i think 2 steps colder plugs). with this small setup, i was fine, no problems.

 

a 190 should be just fine, I'm pretty sure it will support ~500hp. Just nab a walbro off ebay, they're fairly cheap, like around $85 + S&H. Not nearly as loud as the 255, either.
