Will I need bigger injectors?

[306Power]

After I do my PI swap and run a 100 shot of dry nitrous will I need bigger injectors? Or will a dyno tune do the trick? My engine mods would only be PI heads/cams/intake, 100 shot of dry nitrous, CAI, and a 75 mm throttle body. Im getting it tuned afterwards anyways, just didnt know if I would need bigger injectors or if it could be tuned to even out the a/f ratio and save that to a handheld tuner. Thanks for any help.

Yes you will need bigger injectors and a fuel pump. I ran out of both at 300RWHP NA. What year is your car?

The car is a 97, do you know what size I should go with on the fuel pump and injectors? Thanks for your help man.

Tyler, a set of 24lb injectors will me more than enough. That is what I had in the car when I had the 100 shot set up.

Oh and a focus fuel pump.

Thanks Nick I was thinking that a set of 24's would do it. I thought there was a difference on the Pre-1998 GT's on the fuel system that makes it hard for me to run an SVT Focus fuel pump. I could be completely wrong on that though.

[OrangeStang04]

Not sure on the pre-1998 gt's. But any 255lph pump would be ideal for what you are looking to do.

1996-97, 1998's, and 99+ all had different fuel pump set ups. 98 was the bastard year that had a mix of early and later parts. Walbro makes a drop in 255 lph replacement that runs about $120. 24 lb. injectors should be adequate but if you can pick up 30's it might not be a bad idea. If it were me and I were going with 24 lb injectors I would probably throw on an adjustable fuel pressure regulator as well.

I think Im going to wait a few weeks to get the fuel needs. Thanks anyways though.

I think Im going to go with a walbro 255 lph, a set of ford racing 24 lb injectors, a bbk adjustable fuel pressure regulator, and probably just a summit brand mass air flow sensor to compensate for 24 lb injectors. Thanks guys!

You don't need a maf. Stock one will surfice plenty. The maf can be fine tuned. You won't max out a stocker running na. The other stuff will be helpful though. Search around ebay and corral for some stuff.

So even though Im running a 100 dry shot I wont need a new maf? Saves me a few hundred.

[cstreu1026]

You should be fine but for $100 what that guy offered sounds like a good deal.

[306Power]

After looking around at the price of injectors and maf's it defenitly is a good deal, I'll have to get with him on that.
