Swapping a 4.0 sohc into a 99 ranger with 3.0 v6

[lil_Blue_Ford]

Turbo is out of the question as they are stupid expensive and I’m pretty sure I would need a separate intake to go with it.
This shift kit you speak of how does it work? My knowledge of automatic transmissions is limited all I know is there is more to go wrong. I thought a “shift kit” was just for replacing the solenoid springs and some clutches springs… . Not sure how that would affect your ability to spin the tires, unless it changes the shift pints or the gear ratios. Besides that you are talking about the 4.0. Of course it’s got power.

Ehh, if you can weld and fabricate, a turbo isn’t stupid expensive, and you would just dump it right down the throat of your stock intake assuming it’s aluminum and not plastic.

Shift kits go in the valve body mostly. At least with the TransGo kits. Drop the pan, filter, and remove the valve body. Changes springs and valves in the valve body, plus you usually drill out a couple holes in the valve body and separator plate. Firms up the shifts and remedies issues with the stock design. I didn’t expect a whole lot out of it when I did it to the A4LD, but it was night and day. My manual transmission 3.0 would have spanked that 92 4.0 auto before the shift kit. After? Not so much…

I have some video I’ve been fighting with trying to get in a useable format from when I did the shift kit in the 92. One of these days I’ll get it handled. I’m getting ready to do a Stage 2 shift kit combined with a Jmod in my green Ranger, but that is a 4R70w trans. I will get video of that. My buddy Paul is talking about doing a shift kit in his 98 Ranger and I intend to get video of that, which will use the same shift kit you would.

Unless the ranger intakes are more fragile than others for whatever reason.. plastic can take boost just fine. Loads of LS guys running 21+ lbs through stock intakes

I stand corrected on the plastic intake then.

Also, you’re not going to be able to put 21+ lbs of boost through a stock Ranger bottom end unless you’re not worried about it lasting. Realistically you’re probably 10 psi or less to be on the safe side.

 

[I support common sense]

I like the idea of a turbo or supercharger, and if you could point to me a cheap one I might try it, but I don’t want to be running high octane fuel, this is still my only vehicle making it my daily driver.

The one junkyard local to me sells turbos for like $50. I know there’s some YouTube videos about doing it to Rangers with the 3.0, apparently the flex fuel variety is the most ideal because you can mix pump gas and E-85 and it’s supposed to work like higher octane gas. I honestly haven’t dug into it yet since that project is a little ways off for me, I need to fix my green Ranger, Choptop and dump truck before I worry about anything like that.

swap a 4.0 into your truck is essentially the same as swapping in a 5.0... so a guy really oughtta just go full ham on the v8 swap..

Any idea how a 302 plays with TTB? I know Ford didn't bother.

Huh?

Ford only put the 302 in explorers with IFS. I believe this to be true.

He has a ttb ranger with a 302

Found the article in the tech library.

TLDR: fox oil pan, log manifolds, and an oil filter relocation kit is necessary.
