i have b16 w/cams and most likely gonna stay na...im hoping for 200whp. Will the 190lph be sufficient or should i go with the 255lhp or the hp one? the bigger ones are only $10 more.

 

If the car will always be NA then the 190 LPH will do fine. The 190 LPH can handle up to 600-700cc injectors. The 255's can handle injectors as high as 1000cc's. So those fuel pumps are good for that much power. Your fuel requirements wont be anywhere near that, so 190LPH or maybe even a sotck pump in good working order. I think a stock EF fuel pump is like 90 LPH? which can handle a max of about 350cc's. But that's assuming it's in good working order.
