Whipple vs 4.0SOHC
I need more power outta my truck, for about the same amount of money i could find a wrecked 4.0 ranger and part it out from what i need and sell whatevers good and still be ahead of supercharger, as far as reliability is concerned. Anybody know of a good info site on the 4.0SOHC?

Also, you will need to swap the PCM, engine/trans wiring harness and Y-pipe. In all likelihood, your 02 Edge already has an 8.8 axle that you will need to handle the output of the 4.0L.
The most logical donor would be a 2002 but a 2001~2003 should be very compatible. 2003's have no EGR which is a reliablility plus, IMO. Supposedly, the 2003-up have the tensioner problem completely fixed ... The 2004+ have wiring and intake differences but could be adapted if necessary.

I've been weighing this same choice myself. The 4.0 gets terrible fuel milage, but the whipple dictates high-octane fuel. The dark-horse 3rd candidate is a 5.0 swap. That would afford me more power than a 4.0, with fuel economy comparable to a mildly modded 3.0, but the initial expense and difficulty would be greater on an order of magnitude.

It weighed about the same as my porker Level II. I don't know if it would be a good idea to go all the way to 3.08 but 3.31 should be about right on a Ranger with 31" tires.

What kind of mileage do you see these days Bob? I suppose you should qualify that w/ how you drive it..
I've been baybing it lately (early shifts, no more than 2k except on the Interstate, and never more than 70 MPH). I'm seeing mileage as high as 18-20 MPG. .. Which I find a pleasant surprise..

Well selling it is out of the question, I love my truck, plus i couldn't get the tremor system with a 4.0. Also a 4.0 would be better bet for me over supercharger, I was just curious of any write ups on the swap, found alot for the ohv engine, and a few for the ohv to sohc but none 3.0 to sohc.
thanks for the tips bob, rwenzing

With 3.73's I was averaging 240Miles per tank ( about 16 gallons ).. 15mpg. I put in 3.55's about 2 weeks ago and now average 290 ( 18mpg )over the 3 tanks that I have drained ( Empty usually requires 16 gallons for me. ).
I didn't notice any ' loss of launch ' to be honest. I MIGHT try some 3.31's over the winter to see what happens.
To reply back on topic.. I've helped with a 3.0 to 4.0 swap in an 02 tremor. Its a time consuming process ( would be faster at it now havign learned ) but it did take the 4 of us a whole day and the next morning.
Price comparrison speaking, If your states emissions are lienient, a good v8 swap is the best way to go. Its time consuming but the tunability and rewards are worth it.
