Having a problem with starting my FD. I'm not sure its the pump but thats on my list of things to check so I figured I'd ask the question before I got started. I know people recommend an upgrade to the Supra TT fuel pump because it performs better and it's not crazy expensive but my question is this: With no mods other than an intake (for now) will putting on the Supra pump adversely affect the car? ie Flooding and running rich.

 

I would suggest the RX7.com pump: http://www.rx7.com/store/rx7/fdfuel.html


As far as adverse effects, the FPR controls the flow. As long as you don't select a pump which can overrun the stock FPR, then your fuel supply will remain stock. As an added benefit, it's been noted that the stock fuel pump sort of runs a little light as boost increases even at moderate levels of 12 PSI. Have an aftermarket fuel pump can help in those situations making sure you are able to supple the amount of fuel your car needs.
