I know it's 2X as much $, but check out the Super FMU at the bottom of the Jegs page. You don't need to specify 6:1 or 8:1, it's completely adjustable for your fuel curve. If you got a 6:1 unit it means the regulator will add 6psi of fuel pressure for every 1psi of boost it senses.

More fuel pressure is needed for turbo. I know that the SFMU is double the price but it's WAY better. You should seriously consider it man.

Are you speaking from turbo experience or something you read on the net?

On the FMU? Turbo experience, a friend had an turbo Integra I helped tune. We started with an FMU (8:1 I believe). It was pretty bad on gas, and didn't seem to have enough power. He picked up a SFMU and a Wideband O2 (I know $$), after we got it set up properly his car was making a lot better power and his gas mileage improved. Eventually he got rid of the SFMU and installed a re-programmed ECU. I do know that a turbo programmed ECU is not an option for us Neoner's, so that's why I suggested the SFMU as a better tuning option.

ok spud here's how it works-when on boost the fuel pressure should rise with the boost. 1 to 1 is exactly that 1 pound of boost=1 pound of fuel. this is usually done with a rising rate fuel pressure regulater. IT's connected to boost source(boost referenced). as boost comes up so does the fuel pressure it does this by not allowing as much fuel to return to the tank. they are also adjustable to set your off boost fuel psi-helpful when running larger injectors. aeromotive is just a brand. A 255 lph should flow more than enough fuel to support your combo-only thing is your supply line may be too small-i kinda doubt it though.
example....if you run 43 psi at idle you'll need 53 psi with 10 psi of boost this may be confusing at first but any questions i can help

ok, so can sumone please give me a good idea or a link or sumthing as to what EXACTLY i should get to do this....it just always seems that sumone says i should get sumthing because i need it, then i end up finding out its the wrong thing......i just want a solid answer to what i need....

i bought an agp adjustable wastegate because i was told it was the only way to lower the stock boost pressure....spent 80.00 on a used one, then come to find out that the stock wategate is only rated at what i need.....so it sux that i spent more money that i didnt need to, same with the fuel pumps....i am just getting tired of spending needed money on stuff that i dont need....

please help

From a guy I know who is running the SRT-4 turbo on his DOHC...
I'm using a 1:1 from aeromotive, so that is what I'd recommend.
