Going to supercharge my 93GT over the winter,low boost 6-8psi only, and I have a friend who will give me a used Walbro 190gph fuel pump. Will this pump supply enough fuel for me or do I need to go 225gph? Car has Typhoon upper/lower, Steeda 18 cam, ported e7's, 1.7rr, 65mmtb, 70mm maf. I know I will need to upgrade injectors and get matching maf.

Also, can I go 30lb on injectors or 42lb? Car is just a weekend/nice weather cruiser.

You'll need a 255 in tank made for a blower operation. If that's all the boost you're sure you're gonna run, 30's will be plenty. But if you're like most, you'll end up wanting more and will have to spend the money again. be sure of what you want, spend money once.

Thanks for the info Pro. So I guess what your saying is go with a 255lph High pressure in-tank pump? I was looking on Walbro's site and they offer a 255lph in-tank pumps in standard and high pressure.

Get the 255 high pressure pump with the 42lb injectors. Driveability is going to be a little rough until you get it tuned with the 42's. So I've heard at least. My driveability with my 36's is just like stock and I'm untuned with a S/C set up running 5-6 lbs of boost.

I ran 7psi with a 190lph fuel pump, 30lb injectors and an FMU with 0 detonation or fuel problems. It would be wise to run a 255lph pump and 42lb'ers, but you can get away with with smaller IF you have an FMU.
