Question Fuel pump rewire for N/A...

Okay, I pland to rewire the fuel pump for my N/A. I have heard that N/A cars dont change the voltage at idle like Turbo cars do. Is this true? If I wanted to rewire the fuel pump, could I just send a 12 guage wire and relay to the back and have the old power for the fuel pump engage the relay? Or should I still move the stock relays and such? Anyone have a good writeup on a N/A specific fuel pump rewire? Thanks.

I plan on doing this over thanksgiving holiday. Where is a good write up on this. Hopefully it will fix my big power drop at 3800rpm.

that is exacly what you need to do, just make sure you have a fuse near the battery on the wire.

I don't think that has anything to do with it. add a ground from the battery to body. and one from body to engine. you might also have to reground the ecu and boost sensor.

N/A do not have the voltage drop, so why would you want to do it? Puzzled.

I hear that this has helped with the mysterious left hand turn fuel cutout... as well as replacing the in-tank filter.
