Half-assed searched, and kind of confused.
I'm goign to be going with a 3L hybrid with SVT heads so I can use my existing LIM/UIM etc. Its been recommended that I put in 19# injectors.
SVT came with orange and green 19# injectors, did it also come with a bottom feed type? If I have to use top-fed, that means using a different return-style fuel rail. Will I have to change my injector wiring harness to use the other (probably early SVT) fuel rail? The early SVT's had a return-style rail right?
If I install the 19# injectors, can I get away with installing a SVT MAF and will it run ok? Or should I stick with my 17# injectors and stock MAF until just before I get the chip burned (like, through the break-in period of 1000 miles)?

you can use 17s for break-in, i would recommend to stay below 5K though, as they will lean out up top!
the svt injectors need a new fuel rail, they are cheap, i paid like $25 shipped or something for mine. keep in mind you gotta change the connectors for the injectors too!
i ran 19s with no tuning for a little bit, the car will throw a CEL for running rich!

Thats if you use the green injectors though, you don't have to change connections for the orange 19# injectors right?

Did you run the 19's with your stock MAF or did you try to use a SVT MAF (which would be calibrated for the 19s) to compensate?

So I'm wondering if I used a SVT MAF, which is calibrated for 19# injectors, if I would be just right. Might not even need a tuned chip?
Did they ever make the orange 19# injectors bottom feed though? If they did, I could use my existing fuel rail.

The injector size is controlled by the PCM and not the MAF or it's calibration.

you will also need the lim, if you have the side feed vs. the top feed injectors, the lowers are different,

If you're not strapped for time, you can find take out 19# injectors on Ebay for around $80 a set of 8 (Mustang). The electrical connector will be the same as your stock connectors. Just make sure your wires are in good shape as the coating can become brittle over time.
Get a fuel rail from a '98-'99 and a LIM from a '98-'00 2.5L as they will mount up the same. You will have to get creative and extend the fuel rail to meet your car's chassis fuel lines though, just FYI. Make sure to use fuel injection rated hose and connectors, or there will be a big fuel filled ballon popping party under your hood. 
No car came with 19# side feed injectors to match your pre'98 tour rail. The only other car that even has those style injectors that I know about are '93-'97 Ford Probes, and they were all 17#'s.
