S4 Streetport fuel needs
 

So I might be acquiring a 86 FC with an Atkins streetport. It may be a great deal, but it has fuel needs. It is running on the stock 460s, not exactly enough for the car; stock pump, computer and S4 Fuel Injection system.

What I am asking is what would be the best route for upgrading the fuel?

1. Get larger injectors, pump, reprogramed computer and a SAFC. In that case what size injectors would I need?

2. Get rid of the Fuel Injection and get a Weber setup, with a pump.

Also what gph of pump would I need?

Thanks for the input,

you could get away with a pump and an safc, a reprogrammed ECU is essentially a mapped richer but is not tuned, you can tune an SAFC so i would say go that route or go standalone if you got the money. you can't run out of room to work with stock injectors on an n/a so don't bother upgrading the injectors just the pump.

Cool, thanks for the input any fuel pump recommendations?

I forgot, the car would come with a Jakobs rotary master ignition, not installed but that is not difficult to remedy.

What other mods besides the streetport? I wasn't aware that atkins did any porting large enough to need more fuel than stock. An s-afc would help fine tune things, but I doubt you need any larger injectors, *maybe* a TII fuel pump or something, but with just a streetport and mild mods I don't see you needing more fuel.

How do you know it needs more fuel?

exhaust, high flow cat, header, k&N.

The seller says it the TPS might need adjusting and timing too.

At the very most you might need a TII pump, but even that's doubtful. The best fuel mod you could put on would be a fuel controller, so you can tailor the mixtures to the engine's mods. Most likely you will be removing fuel, not adding it.
