If I upgrade my fuel injector to a larger size, do I need a larger fuel pump, or can the stock pump do it? I am replacing the injectors and I was also wondering what are the best injectors to buy, and much they cost.

 

i think it would be advantageous to spend a little more and get an upgraded fuel pump, to relieve the strain and stress from your stocker. i think the most popular fuel pumps are the bosch and 20b cosmo pump. i think the stock supra fuel pump is supposed to be compatible too, but i havent heard about too many people with this setup. what size/brand injectors are you popping in?

 

Nippodenso 1600cc. Basicly I think my injectors are going south, and need to be blueprinted or replaced. I figured I'd replace them so I could get more fuel into the car. Also, doesn't the Viper's fuel pump fit in the 7?

 

viper??? i havent heard about that one, but maybe...
that would be able to pump a lot of gas.

good luck with your fuel delivery project, anyway, whatever you decide on.
