by reading board, i see alot of jeep/ford crossover

with the 8.8 rear ends, the 5.0 injectors, and other various cross-overs

is this just happen stance or is there a reason for this?

can someone go more in-depth in what ford stuff works?

I think it's just that they are plentiful, and therefore cheap. There are so many explorers and 5.0 motors in the junkyards and on Craigslist, that the parts are relatively cheap and readily available.

You can use Neon injectors which are supposed to be just as good if not better than 5.0 injectors, but you're more likely (like I was) to come across a mustang guy selling his stock injectors cheap because he upgraded.

I believe a Subaru e-fan may work also, but there are way more 3.8L fords around here.

There are a bunch of junkyard axles to use, but not many as plentiful and with little to no off-road use as the 8.8 from a 95-01 explorer.

So I think it's just that there are so many around, it's easier and cheaper to use ford parts.

Here's a shot of my 5.0 injectors, I also have a Taurus E-fan.

So I know this is the YJ section but I'm looking to do the same with my TJ. Did the ford injectors make a big difference? What happen to fuel economy? (not looking for an increase but defiantly not a large drop) did you end up changing out the throttle body? Did you need hotter plugs to run it right?

I don't think they made a huge difference but it seems like a lot of little things that make it drive a little better.
-improved idle
-improved mpg
-improved acceleration

Those are the things that you notice. It was a $80 install for me including everything (injectors, o rings, fpr). I think it was well worth it. And I have 2 extra injectors.

I didn't change the throttle body. You just install the injectors and the appropriate FPR. It was easy as all hell. I did it at the same time I changed my exhaust manifold. Running the same plugs, same everything. All you are doing is using a 4 pintle injector instead of the stock single pintle injector. The idea is that with 4 pintles the gas comes out as more of a mist, rather than a stream. The mist should help in a more complete burn, rather than a squirt from the injector where not all the gas gets burned. That's really it. Not forcing more gas. Just using the gas more efficiently. In theory. I think it works.

What FPR did you use? Also any tips on removal and instal on the injectors? Have had mine for over a year, and need to get them in.

Absolutely right. Generally if there are a million of something out there, the prices drop fast and they are plentiful for parts. I know that's a low of why I went with the 8.8.

I used a 90s Town and Country FPR. I don't remember exactly what year or engine. I'll look it up in a second.

As for advice on replacing injectors. KEEP THE WIRES IN ORDER. The last thing you want is to button the fuel rail up and realize that you crossed wires and you have to start over. I changed them one at a time so there was no doubt about what wire and slot the injector was supposed to be attached to. It wasn't hard but you don't want to have to do a job twice.

Slow is smooth and smooth is fast.

P.S.
Have a few rags ready and don't smoke. I had a bunch of gas in the rail and it got everywhere.
