Hello. I wouldnt worry about "Option 2". Basically you would only need to change your fuel rail if you changed your 39psi fuel pressure regulator for the 49psi one. I tried both the 39 and 49psi ones in my own Jeep and really noticed no difference performance or MPG wise to make it worth worrying about. The injectors for both Option 1 and Option 2 are the same it's just the psi at the fuel rail which changes. You can find the #703 injetors in a variety of Dodge/Chyrsler cars from the mid-90's as well as a few minivans. But be careful of the 740's which look exactly like the 703's but are about 1/2" shorter as they won't work. If you strike out getting the 703's there are always the Ford #710 "yellow stick" ones which will be a nice upgrade as well.

I got the "703" dodge stratus injectors... known as "neon injectors". I have them in my 89 I6 with a 5 speed and i love them! I didn't have to put on a new fuel pressure regulator, and it made my jeep run SO much smoother.... and it gave me a bit more power too! i would recommend them!

When I went looking for my injectors, the list I had didn't help me at all. I resorted to checking every chrysler vehicle in the lot. I was looking for 784s. But its pretty easy to see the numbers on the side of the injector. I know its frustrating not knowing exactly which vehicle(s) to look for but it doesn't take that long to look through them. I do remember seeing the 703's on alot of neons. and plymouth breezes.

As was mentioned the years and models are listed on the chart where you saw the "Option 1 & 2" stuff. However not ALL of the cars of each year/model will have the 703 injectors as only specific engines did. But that will narrow your searching down a lot. Just memorize what they look like from the photos and look for the part # on the side when you are at the junkyard

for option 2, yes. The only reason I suggested option 2 is so you can get better pressure, but it's not necessary. Option 1 will work fine , which is just the injectors. Most 97-01 dodge stratus' with the 2.0 4 cyl have 703's, as do most 97-02 neons. If you can't find them, you can buy a set from guys on here that get them, clean and test them, then sell them in the "for sale" section (Programbo sells 'em, as do I).
