im wanting to upgrade my fuel system, i plan on walbro 255, 720cc secondaries, and SAFC so far... the main reason is i have some nitrous stuff, i plan to finish getting all the nitrous stuff i need together and putting it on the car, is there anything else i should look into for upgrading my fuel system?....mods in sig

Maybe an aftermarket FPR. And I would scrap the SAFC, go to a "real" stanalone, that way you have some control of ignition timing.

 

so theres no need for an SAFC whe you have standalone? explain, ive never looked into standalone...

 

I dont think you need 720s if you have an NA, even if you have nos. :S

 

I agree...you could always use the stock 550cc TII injectors. I'm sure you could find some used ones cheap. Just make sure you send them out to be professionally cleaned before installing them.

 

if you have as5 t2 how much hp can get until you need to upgrade the fuel with bigger injectors and fuel pump

 

You don't need injector upgrades for N2O. You just use a wet kit and it injects the right amount of gas with the N2O. The only thing you may want to do is get a Walbro fuel pump. DO NOT run a dry kit.

As far as my understanding, SAFC's are piggyback fuel management. As in, they piggyback on your stock computer system in your car. A standalone just replaces those computers and serves as fuel management along with a lot of other functions.

I might of explained that badly... or I might be retarded. Feel free to correct me someone.
