fuel system i plan on putting a fast 90/90 combo on my car. I am going to replace the maf with a slp 85mm maf and im going to replace the fuel rails and lines. my question is do i need to change the fuel pump right away or can i wait. plan on doing it just need to save some cash. car will be putting down about 500 rwhp when done. how much hp can a stock fuel pump support?
Thanks for any help

I am pretty sure the stock fuel pump is pretty much maxed out at around 400rwhp or so but Im not sure. I would replace the one in the tank first and then check and see how lean when you strap it to the dyno with a air fuel monitor/guage hooked up monitering to see if your lean at wide open throttle. You will need a set of injectors more than likely and it looks as if you already need them (478) because I dont see in your signiture that you have changed the injectors. The 1999- 2000 had the smallest injectors I am pretty sure also 26lb.
