Hey guys,
Car is an RX7 with forged LS6 (stock cubes), PRC stage 2.5 5.3L heads and TSP 228R cam, Nitrous Express EFI Single nozzle wet kit with the 175HP jetting.

Last year with the 125HP jetting the car made 551HP and 662 FT/lbs at the wheels.

Now that I am moving up to a 175 shot I want to make sure the walboro 255 can push enough fuel. If not is there another pump that I can swap easily to replace the walboro 255?

Thanks!

With the hotwire kit it should be enough, but the pump on its own might not be

I have seen the "hotwire kit" mentioned a few times but I don't know exactly what it is. I will take a quick look and do some research. Thanks!

No problem. Yeah it basically boosts the voltage to pump and allows it to pump more fuel. I think it's good for another 50-100 hp over the fuel pump alone
