4.6 injectors on 3.7
I read that someone put 3v 4.6 injectors onto the Dakota and got good power gains, enough to actually do a burn out from a stop which our trucks can't do with the 3.7. What injectors can we all use? How about 2v injectors? Those are cheaper and I have a crown vic that i can take them off, but not sure if anybody has done it with other ones.

i've done multiple burnouts with my dac on dry pavement at will on the stock tires. I have 3.92 gears in mine, so that helps i guess. All i did to my truck was E3 spark plugs and a K&N drop in filter.
Well, it's a one tire fryer as it's an open rear diff as well, but it's possible.
I even entered a burnout contest and everyone laughed at me when i pulled up, but i impressed them all... i didn't win or even come close, but everyone was impressed that my truck did so much smoke. It was billowing out from the other side of the bed when i finally stopped. Before i got my tires swapped, i found a nice patch of pavement (which is tough in Northern Ontario in January) and pretty much burned the tread off those crappy SR/A tires. The Grabbers i have on it now are too grippy to be able to do a burnout on dry pavement. I think warped my rotors by pressing my brakes so hard trying to get the rear loose. They weren't warped before i tried my last dry pavement burn out with my grabbers.

Oops, I forgot the second part of my post.
JKeaton is correct, it will do nothing to the truck other then make it throw codes. larger injectors would only be needed if doing something that required more fuel, like a turbo, or NOS. without the need for more fuel, you will kill and/or clog your catalytic converters in no time and in result, possibly the rest of the engine. and from what i hear, the 3.7 doesn't like power adders.

The computer will compensate for the rich condition, that not the point. Someone else on the forum did it with no issues. Go search for the other post, probably a few years old tho. They believe that it is the spray pattern that makes the difference. Just wondering if anybody else has done this and what injectors you have used because I want to use my 2v injectors while the other post used 3v injectors.

Nick Whalen did it on his, but he ran rich. But, yes the computer will eventually compensate for the extra fuel, and then it's really doing nothing by changing them in the first place. I bought a set for mine but never installed them after reading the various schools of thought. Seems like lots of opinions on the issue though.
