I have a walbro 190 fuel pump in my car and im looking to get 300whp when i go boosted out of a 57 trim on my b16 with gsr cams. Will this hold up or will i have to get the walbro 255hp pump. I will be using a b16 with pistons and rods soon with a built head and want to run e85 that ill be looking for 450whp or so with a 60-1 or t70. i have 780cc injectors for the pump gas for stock and will have 1000cc for the e85 on biult. Will the pump handle the 300whp on stock with 93 pump or should i just put in the 255hp pump now. thanks
