Nippondesno makes a nice pump rated at 500hp. A lot of RX7 guys are using these. SRMotorsports says it is a direct swap for our stock pump. http://www.rx7store.net sells them for about $100 cheaper than SR Motorsports.TDK said:What options do we have in regards to in-tank fuel pumps for the P5. I currently have a Walbro 255. I want to change it because it doesn't sound like it will last too long. Does Bosch make a pump?
