Yea, I've got 60lb. Mototrons, a racetronics pump, PnP harness, and a KB BAP sitting here waiting to go on my car as well (fuck you PTK...), but, I plan on adding to that as I don't think it'll support more than 600-650whp safely. I won't know for certain until: 1. I actually get my turbo kit, and 2. I start tuning to see when the fuel pressure starts to drop off.
Have you upgraded to a return style system yet? If not, I'd recommend doing so. Either that, or do like Sam did and go with a progressive controller so there isn't as much of a shock on the fuel system when the nitrous hits.
I eventually plan on going with twin pumps, 1:1 fuel pressure regulator, and a complete return system.
Good luck with your project. You get Eric's old kit hooked up yet?
p.s. Some folks over in the LS1tech vette section were asking about your car a few weeks back.
